49 | });
50 |
51 | // WRONG! Missing autoDispose, family, etc.

173 |
174 | ### 2. Add to Your AI Assistant
175 |
176 | <details open>
177 | <summary><strong>Claude Desktop</strong></summary>
178 |
179 | Edit `~/Library/Application Support/Claude/claude_desktop_config.json`:
180 |
181 | ```json
182 | {
183 | "mcpServers": {
184 | "flutter-docs": {
185 | "command": "npx",
186 | "args": ["flutter-mcp"]
187 | }
188 | }
189 | }
190 | ```
191 |
192 | Or if you installed globally:
193 |
194 | ```json
195 | {
196 | "mcpServers": {
197 | "flutter-docs": {
198 | "command": "flutter-mcp"
199 | }
200 | }
201 | }
202 | ```
203 |
204 | Restart Claude Desktop after saving. The server will automatically install dependencies on first run.
205 |
206 | </details>
207 |
208 | <details>
209 | <summary><strong>Claude Code (claude.ai/code)</strong></summary>
210 |
211 | Create a `.mcp.json` file in your Flutter project root:
212 |
213 | ```json
214 | {
215 | "mcpServers": {
216 | "flutter-docs": {
217 | "command": "npx",
218 | "args": ["flutter-mcp"]
219 | }
220 | }
221 | }
222 | ```
223 |
224 | Then run Claude Code in your project directory:
225 | ```bash
226 | cd your-flutter-project
227 | claude
228 | ```
229 |
230 | Flutter MCP will automatically provide documentation for all packages in your `pubspec.yaml`.
231 |
232 | **Alternative: Global npm install**
233 |
234 | If you installed globally with `npm install -g flutter-mcp`:
235 |
236 | ```json
237 | {
238 | "mcpServers": {
239 | "flutter-docs": {
240 | "command": "flutter-mcp"
241 | }
242 | }
243 | }
244 | ```
245 |
246 | **Important:** Don't use the `--dangerously-skip-permissions` flag when running Claude Code, as it prevents MCP servers from being loaded.
247 |
248 | </details>
249 |
250 | <details>
251 | <summary><strong>Cursor / Windsurf</strong></summary>

265 |
266 | <details>
267 | <summary><strong>MCP SuperAssistant</strong></summary>
268 |
269 | MCP SuperAssistant requires HTTP transport. Configure it with:
270 |
271 | 1. Start the server with HTTP transport:
272 | ```bash
273 | npx flutter-mcp --transport http --port 8000
274 | ```
275 |
276 | 2. In MCP SuperAssistant, add a new server:
277 | - **Name**: Flutter MCP
278 | - **URL**: `http://localhost:8000`
279 | - **Type**: HTTP MCP Server
280 |
281 | 3. The server will now be available in your MCP SuperAssistant client.
282 |
283 | </details>
284 |
285 | <details>
286 | <summary><strong>VS Code + Continue</strong></summary>
287 |
288 | In your `.continuerc.json`:
289 |
290 | ```json
291 | {
292 | "models": [
293 | {
294 | "provider": "claude",
295 | "mcp_servers": {

300 | }
301 | }
302 | ]
303 | }
304 | ```
305 |
306 | </details>
307 |
308 | ### 3. Start the Server (Optional for Testing)
309 |
310 | <details>
311 | <summary>Manual server control and transport options</summary>
312 |
313 | ```bash
314 | # Default STDIO mode (for Claude Desktop)
315 | npx flutter-mcp
316 |
317 | # HTTP transport (for MCP SuperAssistant)
318 | npx flutter-mcp --transport http --port 8000
319 |
320 | # SSE transport
321 | npx flutter-mcp --transport sse --port 8080
322 |
323 | # Custom host binding
324 | npx flutter-mcp --transport http --host 0.0.0.0 --port 3000
325 |
326 | # If installed globally
327 | flutter-mcp-server --transport http --port 8000
328 | ```
329 |
330 | **Transport Options:**
331 | - Default (no flag) - STDIO for Claude Desktop and most MCP clients
332 | - `--transport http` - For HTTP-based clients like MCP SuperAssistant
333 | - `--transport sse` - For Server-Sent Events based clients
334 | - `--port PORT` - Port for HTTP/SSE transport (default: 8000)
335 | - `--host HOST` - Host to bind to (default: 127.0.0.1)
336 |
337 | Note: When configured in Claude Desktop, the server starts automatically using STDIO transport.
338 |
339 | </details>
340 |
341 | ### 3. Use It!
342 |
343 | Flutter MCP now features simplified tools following Context7's successful pattern - just 2 main tools instead of 5!
344 |
345 | #### 🎯 New Simplified Usage (Recommended)
346 |
347 | The AI assistant can now use Flutter MCP more intelligently:
348 |
349 | ```
350 | # Universal search
351 | "Search for Flutter animation widgets"
352 | "Find state management packages"
353 | "Look for HTTP clients in pub.dev"
354 |
355 | # Smart documentation fetching
356 | "Show me Container widget documentation"
357 | "Get the docs for provider package"
358 | "Explain dart:async Future class"
359 | ```
360 |
361 | #### 💫 Natural Language Support
362 |
363 | Your AI will automatically detect Flutter/Dart content and fetch relevant docs:
364 |
365 | ```
366 | "How do I implement infinite scroll with infinite_scroll_pagination?"
367 | "Show me dio interceptors for auth tokens"
368 | "What's the difference between bloc and riverpod?"
369 | ```
370 |
371 | #### 🔧 Legacy Support
372 |
373 | The `@flutter_mcp` mentions still work for backward compatibility:
374 |
375 | ```
376 | "Explain @flutter_mcp freezed code generation"
377 | "Show me all @flutter_mcp get_it service locator patterns"
378 | ```
379 |
380 | ### 🎯 Version-Specific Documentation (NEW!)
381 |
382 | Get documentation for specific package versions using familiar pub.dev syntax:
383 |
384 | ```
385 | # Exact versions

400 | ## 📚 Available Tools
401 |
402 | ### 🎯 NEW: Simplified Tools (Context7-style)
403 |
404 | Flutter MCP now provides just 2 main tools, making it easier for AI assistants to use:
405 |
406 | ### 1. `flutter_search` - Universal Search
407 |
408 | Search across Flutter/Dart documentation and pub.dev packages with intelligent ranking.
409 |
410 | ```json
411 | {
412 | "tool": "flutter_search",
413 | "arguments": {
414 | "query": "state management",
415 | "limit": 10 // Optional: max results (default: 10)
416 | }
417 | }
418 | ```
419 |
420 | Returns multiple options for the AI to choose from, including Flutter classes, Dart libraries, pub packages, and concepts.
421 |
422 | ### 2. `flutter_docs` - Smart Documentation Fetcher
423 |
424 | Get documentation for any Flutter/Dart identifier with automatic type detection.
425 |
426 | ```json
427 | {
428 | "tool": "flutter_docs",
429 | "arguments": {
430 | "identifier": "Container", // Auto-detects as Flutter widget
431 | "topic": "examples", // Optional: filter content
432 | "max_tokens": 10000 // Optional: limit response size
433 | }
434 | }
435 | ```
436 |
437 | Supports various formats:
438 | - `"Container"` - Flutter widget
439 | - `"material.AppBar"` - Library-qualified class
440 | - `"provider"` - pub.dev package
441 | - `"dart:async.Future"` - Dart core library
442 |
443 | ### 3. `flutter_status` - Health Check (Optional)
444 |
445 | Monitor service health and cache statistics.
446 |
447 | ```json
448 | {
449 | "tool": "flutter_status",
450 | "arguments": {}
451 | }
452 | ```
453 |
454 | ---
455 |
456 | ### 📦 Legacy Tools (Deprecated but still functional)
457 |
458 | The following tools are maintained for backward compatibility but internally use the new simplified tools:
459 |
460 | <details>
461 | <summary>View legacy tools</summary>

506 | ```json
507 | {
508 | "tool": "health_check",
509 | "arguments": {}
510 | }
511 | ```
512 |
513 | </details>
514 |
515 | ## 🎯 Features
516 |
517 | - **✨ NEW: Simplified Tools**: Just 2 main tools instead of 5 - following Context7's successful pattern
518 | - **📦 Real-Time Documentation**: Fetches the latest docs for any pub.dev package on-demand
519 | - **🎯 Version-Specific Docs**: Request exact versions, ranges, or use keywords like `latest`/`stable`
520 | - **🚀 Zero Configuration**: Automatically detects packages from your `pubspec.yaml`
521 | - **⚡ Lightning Fast**: Intelligent caching means instant responses after first fetch
522 | - **🔒 100% Private**: Runs locally - your code never leaves your machine
523 | - **🎨 Smart Context**: Provides constructors, methods, examples, and migration guides
524 | - **♾️ Unlimited Packages**: Works with all 50,000+ packages on pub.dev
525 | - **🤖 AI-Optimized**: Token limiting and smart truncation for efficient LLM usage
526 |
527 | ## 💡 How It Works
528 |
529 | Flutter MCP is a local MCP server (think of it as a "RAG sidecar" for Flutter) built on the battle-tested Python MCP SDK. It enhances your AI with real-time documentation:
530 |
531 | ```mermaid
532 | graph LR
533 | A[Your Prompt] --> B[AI Assistant]
534 | B --> C{Flutter/Dart Content?}
535 | C -->|Yes| D[Query Flutter MCP]
536 | D --> E[Check Local Cache]
537 | E -->|Hit| F[Return Cached Docs]
538 | E -->|Miss| G[Fetch from pub.dev]

540 | H --> F
541 | F --> I[Enhanced Context]
542 | I --> J[AI Generates Accurate Code]
543 | C -->|No| J
544 | ```
545 |
546 | ### The Magic Behind the Scenes
547 |
548 | 1. **MCP Integration**: Your AI assistant automatically detects when you're asking about Flutter/Dart packages
549 | 2. **Smart Detection**: No special syntax required - just mention package names naturally
550 | 3. **Lightning Cache**: First request fetches from pub.dev (1-2 seconds), subsequent requests are instant
551 | 4. **Context Injection**: Documentation is seamlessly added to your AI's knowledge before it responds
552 | 5. **Privacy First**: Everything runs locally - your code and queries never leave your machine
553 |
554 | ### Performance Notes
555 |
556 | - ⚡ **First Query**: 1-2 seconds (fetching from pub.dev)
557 | - 🚀 **Cached Queries**: <50ms (from local SQLite cache)
558 | - 💾 **Cache Duration**: 24 hours for API docs, 12 hours for packages
559 | - 🧹 **Auto-Cleanup**: Expired entries cleaned on access
560 |
561 | ### Error Handling
562 |
563 | If documentation isn't available or a fetch fails, Flutter MCP gracefully informs your AI, preventing it from generating incorrect or hallucinated code based on missing information. Your AI will let you know it couldn't find the docs rather than guessing.
564 |
565 | ## 📊 What Gets Indexed
566 |
567 | When you request a package, Flutter MCP extracts:
568 |
569 | - ✅ **API Documentation**: Classes, methods, properties with full signatures
570 | - ✅ **Constructors**: All parameters, named arguments, defaults
571 | - ✅ **Code Examples**: From official docs and README files
572 | - ✅ **Migration Guides**: Breaking changes and upgrade paths
573 | - ✅ **Package Metadata**: Dependencies, platform support, versions
574 |

606 |
607 | ## 🛠️ Troubleshooting
608 |
609 | <details>
610 | <summary><strong>Error: spawn flutter-mcp ENOENT</strong></summary>
611 |
612 | This error means the system cannot find the `flutter-mcp` command. Solutions:
613 |
614 | 1. **Use npx (recommended):**
615 | ```json
616 | {
617 | "mcpServers": {
618 | "flutter-docs": {
619 | "command": "npx",
620 | "args": ["flutter-mcp"]
621 | }
622 | }
623 | }
624 | ```
625 |
626 | 2. **Install globally first:**
627 | ```bash
628 | npm install -g flutter-mcp
629 | # Then use:
630 | {
631 | "mcpServers": {
632 | "flutter-docs": {
633 | "command": "flutter-mcp"
634 | }
635 | }
636 | }
637 | ```
638 |
639 | 3. **Check Node.js installation:**
640 | ```bash
641 | node --version # Should be 16+
642 | npm --version # Should be installed
643 | ```
644 |
645 | </details>
646 |
647 | <details>
648 | <summary><strong>MCP server failed to start</strong></summary>
649 |
650 | 1. Check if Node.js 16+ is installed: `node --version`
651 | 2. Try running manually to see errors: `npx flutter-mcp`
652 | 3. The npm package will auto-install Python dependencies on first run
653 | 4. Check if Python 3.8+ is available: `python3 --version`
654 | 5. View detailed logs: `DEBUG=true npx flutter-mcp`
655 |
656 | </details>
657 |
658 | <details>
659 | <summary><strong>Documentation not found errors</strong></summary>
660 |
661 | - Some very new packages might not have documentation yet
662 | - Private packages are not supported
663 | - Try using the package name exactly as it appears on pub.dev
664 |
665 | </details>
666 |
667 | <details>
668 | <summary><strong>Cannot connect from MCP client</strong></summary>
669 |
670 | Different MCP clients require different transport protocols:
671 |
672 | 1. **Claude Desktop**: Uses STDIO transport (default)
673 | - No port/URL needed
674 | - Just use: `npx flutter-mcp`
675 |
676 | 2. **MCP SuperAssistant**: Requires HTTP transport
677 | - Start with: `npx flutter-mcp --transport http --port 8000`
678 | - Connect to: `http://localhost:8000`
679 |
680 | 3. **Custom clients**: May need SSE transport
681 | - Start with: `npx flutter-mcp --transport sse --port 8080`
682 | - SSE endpoint: `http://localhost:8080/sse`
683 |
684 | If connection fails:
685 | - Verify the correct transport mode for your client
686 | - Check if the port is already in use
687 | - Try binding to all interfaces: `--host 0.0.0.0`
688 | - Ensure Node.js and npm are properly installed
689 |

3 | This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
4 |
5 | ## Project Overview
6 |
7 | This is a Flutter/Dart documentation MCP (Model Context Protocol) server project designed to provide AI assistants with seamless access to Flutter and Dart documentation. Following Context7's proven approach, the project uses on-demand web scraping with Redis caching to ensure users always get the most current documentation while maintaining fast response times.
8 |
9 | ## Key Architecture Components
10 |
11 | 1. **MCP Server**: FastMCP server with on-demand documentation fetching
12 | 2. **Redis Caching**: Fast in-memory cache for processed documentation
13 | 3. **Web Scraping**: Respectful fetching from api.flutter.dev and api.dart.dev
14 | 4. **Pub.dev API**: Official API for package documentation
15 | 5. **Processing Pipeline**: Parse → Enrich → Clean → Cache (Context7-style)
16 | 6. **Rate Limiting**: 2 requests/second to respect server resources
17 |
18 | ## Development Commands
19 |
20 | ```bash
21 | # Project setup (using uv package manager)
22 | uv init mcp-server-flutter-docs
23 | cd mcp-server-flutter-docs
24 | uv add "mcp[cli]" httpx redis beautifulsoup4 structlog
25 |
26 | # Start Redis (required for caching)
27 | redis-server # In a separate terminal
28 |
29 | # Development server with MCP Inspector
30 | mcp dev server.py
31 |
32 | # Run the server
33 | uv run server.py
34 |
35 | # Alternative with traditional Python
36 | python -m venv venv
37 | source venv/bin/activate # On Windows: venv\Scripts\activate
38 | pip install "mcp[cli]" httpx redis beautifulsoup4 structlog
39 | python server.py
40 | ```
41 |
42 | ## Core Implementation Guidelines
43 |
44 | 1. **On-Demand Fetching**: Fetch documentation only when requested, like Context7
45 | 2. **Redis Caching**: Cache processed docs with appropriate TTLs (24h for APIs, 12h for packages)
46 | 3. **Smart URL Resolution**: Pattern matching to resolve queries to documentation URLs
47 | 4. **Rate Limiting**: RateLimiter class ensuring 2 requests/second max
48 | 5. **Error Handling**: Graceful fallbacks when documentation isn't found
49 | 6. **User Agent**: Always identify as "Flutter-MCP-Docs/1.0" with GitHub URL
50 |
51 | ## Transport and Distribution
52 |
53 | - **Primary Transport**: STDIO for local Claude Desktop integration
54 | - **Configuration Path**: `~/Library/Application Support/Claude/claude_desktop_config.json`
55 | - **Distribution Size**: <10MB lightweight package
56 | - **Dependencies**: Redis required (local or external service)
57 | - **Distribution Methods**: PyPI package, npm package, Docker image
58 | - **Versioning**: Semantic versioning (MAJOR.MINOR.PATCH)
59 |
60 | ## Implementation Timeline
61 |
62 | 1. **MVP (4 hours)**: Basic server with Flutter API docs
63 | 2. **Week 1**: Add pub.dev support, search functionality
64 | 3. **Week 2**: Polish, documentation, and launch
65 | 4. **Future**: Stack Overflow, cookbook, version-specific docs
```

123 | ruff check src/ tests/
124 | ```
125 |
126 | ### 🧪 Testing Guidelines
127 |
128 | All code changes should include tests:
129 |
130 | ```bash
131 | # Run all tests
132 | pytest
133 |
134 | # Run with coverage
135 | pytest --cov=flutter_mcp
136 |
137 | # Run specific test file
138 | pytest tests/test_server.py
139 |
140 | # Run tests in watch mode
141 | pytest-watch
142 | ```
143 |
144 | We aim for at least 80% test coverage. Write tests that:
145 |
146 | - Cover both happy paths and edge cases
147 | - Are isolated and don't depend on external services
148 | - Use mocks for Redis and external API calls
149 | - Have descriptive names that explain what they test
150 |

1 | # Quick Fix for MCP SuperAssistant Users
2 |
3 | ## For Users Who Already Installed from Source
4 |
5 | 1. **Pull the latest changes**:
6 | ```bash
7 | cd flutter-mcp # or wherever you cloned it
8 | git pull
9 | ```
10 |
11 | 2. **Reinstall with new features**:
12 | ```bash
13 | pip install -e .
14 | ```
15 |
16 | 3. **Start with HTTP transport**:
17 | ```bash
18 | flutter-mcp start --transport http --port 8000
19 | ```
20 |
21 | 4. **Configure MCP SuperAssistant**:
22 | - URL: `http://localhost:8000`
23 | - Type: HTTP MCP Server
24 |
25 | That's it! The HTTP transport support is now available.
26 |
27 | ## Alternative: Direct GitHub Install
28 |
29 | If you haven't cloned the repo:
30 | ```bash
31 | pip install git+https://github.com/flutter-mcp/flutter-mcp.git
32 | flutter-mcp start --transport http --port 8000
33 | ```
34 |
35 | ## Troubleshooting
36 |
37 | If `flutter-mcp` command not found:
38 | ```bash
39 | python -m flutter_mcp.cli start --transport http --port 8000
40 | ```
41 |
42 | Or from the source directory:
43 | ```bash
44 | cd src
45 | python -m flutter_mcp start --transport http --port 8000
46 | ```
```

/docs/DEVELOPMENT.md:
--------------------------------------------------------------------------------
```markdown
1 | # Flutter MCP Server Development Guide
2 |
3 | ## Quick Start
4 |
5 | 1. **Install Redis** (required for caching):
6 | ```bash
7 | # macOS
8 | brew install redis && brew services start redis
9 |
10 | # Ubuntu/Debian
11 | sudo apt-get install redis-server
12 |
13 | # Docker (alternative)
14 | docker run -d -p 6379:6379 --name flutter-mcp-redis redis:alpine
15 | ```
16 |
17 | 2. **Run the test script**:
18 | ```bash
19 | ./test-server.sh
20 | ```
21 |
22 | This will:
23 | - Check if Redis is running
24 | - Start the MCP Inspector
25 | - Open a web interface at http://localhost:5173
26 |
27 | 3. **Test the tools** in MCP Inspector:
28 |
29 | **Get Flutter documentation:**
30 | ```json
31 | {
32 | "class_name": "Container",
33 | "library": "widgets"
34 | }
35 | ```
36 |
37 | **Search Flutter docs:**
38 | ```json
39 | {
40 | "query": "material.AppBar"
41 | }
42 | ```
43 |
44 | **Get pub.dev package info:**
45 | ```json
46 | {
47 | "package_name": "provider"
48 | }
49 | ```
50 |
51 | ## Development Commands
52 |
53 | ```bash
54 | # Install dependencies
55 | uv sync
56 |
57 | # Run server directly
58 | uv run server.py
59 |
60 | # Run with MCP Inspector (recommended)
61 | uv run mcp dev server.py
62 |
63 | # Run without uv
64 | python server.py
65 | ```
66 |
67 | ## Testing with Claude Desktop
68 |
69 | 1. Add to Claude Desktop config:
70 | ```json
71 | {
72 | "mcpServers": {
73 | "flutter-mcp": {
74 | "command": "uv",
75 | "args": ["--directory", "/path/to/flutter-docs-mcp", "run", "server.py"]
76 | }
77 | }
78 | }
79 | ```
80 |
81 | 2. Restart Claude Desktop
82 |
83 | 3. Test with queries like:
84 | - "How do I use the Container widget in Flutter?"
85 | - "Show me the documentation for material.Scaffold"
86 | - "What's the latest version of the provider package?"
87 |
88 | ## Architecture
89 |
90 | - **FastMCP**: Handles MCP protocol and tool registration
91 | - **Redis**: Caches processed documentation (24h for APIs, 12h for packages)
92 | - **Rate Limiter**: Ensures respectful scraping (2 requests/second)
93 | - **HTML Parser**: Converts Flutter docs to clean Markdown
94 | - **Structured Logging**: Track performance and debug issues
95 |
96 | ## Common Issues
97 |
98 | 1. **Redis not running**: Server works but responses are slower
99 | 2. **Rate limiting**: First requests take 1-2 seconds
100 | 3. **404 errors**: Check class name and library spelling
101 |
102 | ## Next Steps
103 |
104 | - [ ] Add pub.dev README parsing
105 | - [ ] Implement @flutter_mcp activation
106 | - [ ] Add Flutter cookbook integration
107 | - [ ] Support version-specific docs

--------------------------------------------------------------------------------
```markdown
1 | # Flutter MCP Ingestion Strategy
2 |
3 | ## Content Extraction Priorities
4 |
5 | When we say we "support" a Flutter/Dart package, we extract and process the following content in priority order:
6 |
7 | ### 1. Essential Content (MVP)
8 | - **Doc Comments (`///`)**: Primary source of API documentation
9 | - **Class/Method Signatures**: Full signatures with parameter types and return values
10 | - **Constructor Parameters**: Named parameters, required vs optional, default values
11 | - **README.md**: Package overview, getting started, basic examples
12 | - **pubspec.yaml**: Dependencies, Flutter/Dart SDK constraints
13 |
14 | ### 2. High-Value Content (Week 1)
15 | - **Example Directory**: Complete runnable examples showing real usage
16 | - **CHANGELOG.md**: Recent version changes, breaking changes, migration guides
17 | - **Type Definitions**: Enums, typedefs, extension methods
18 | - **Export Statements**: Understanding the public API surface
19 |
20 | ### 3. Context-Enhancing Content (Week 2+)
21 | - **Test Files**: Understanding expected behavior and edge cases
22 | - **Issue Templates**: Common problems and their solutions
23 | - **Migration Guides**: Version-specific upgrade instructions
24 | - **Platform-Specific Code**: iOS/Android/Web specific implementations
25 |
26 | ### What We DON'T Extract
27 | - **Full Method Bodies**: Too much noise, not helpful for LLM context
28 | - **Private Implementation Details**: Focus on public API only
29 | - **Generated Code**: Skip `.g.dart`, `.freezed.dart` files
30 | - **Build Configuration**: Detailed build settings aren't useful for API questions
31 |
32 | ## Semantic Chunking Strategy
33 |
34 | Instead of naive text splitting, we chunk semantically:
35 |
36 | ```
37 | CHUNK 1: package:provider, version:6.1.1, type:class
38 | # ChangeNotifierProvider<T>
39 | A widget that creates a ChangeNotifier and automatically disposes it.
40 | Constructor: ChangeNotifierProvider({required Create<T> create, bool? lazy, Widget? child})
41 | ...
42 |
43 | CHUNK 2: package:provider, version:6.1.1, type:method, class:ChangeNotifierProvider
44 | # static T of<T>(BuildContext context, {bool listen = true})
45 | Obtains the nearest Provider<T> up its widget tree and returns its value.
46 | ...
47 | ```
48 |
49 | ## Metadata Enrichment
50 |
51 | Each chunk includes:
52 | - Package name and version
53 | - Source file path
54 | - Content type (class/method/example/changelog)
55 | - Null safety status
56 | - Platform compatibility
57 | - Last updated timestamp
58 |
59 | This approach ensures high-quality, relevant context for LLMs while keeping storage and processing costs manageable.

/docs/planning/project-summary.md:
--------------------------------------------------------------------------------
```markdown
1 | # Flutter MCP Project Summary
2 |
3 | ## Vision
4 | Create the Context7 of Flutter - an MCP server that gives AI assistants real-time access to Flutter/Dart documentation, positioning it as the essential tool for Flutter developers using Claude, Cursor, or Windsurf.
5 |
6 | ## Key Innovation: On-Demand Package Support
7 | Instead of pre-indexing 35,000+ packages, we use an on-demand model:
8 | - User requests `@flutter_mcp provider`
9 | - System fetches, processes, and caches package docs in ~30 seconds
10 | - Future requests are served instantly from cache
11 |
12 | ## Technical Architecture
13 | - **Core**: Python FastMCP with Redis caching
14 | - **Fetching**: On-demand from api.flutter.dev, pub.dev API
15 | - **Processing**: HTML → Clean Markdown with semantic chunking
16 | - **Activation**: `@flutter_mcp package_name` in prompts
17 |
18 | ## Marketing Strategy
19 |
20 | ### Positioning
21 | "The first AI companion that supports ANY pub.dev package on-demand"
22 |
23 | ### Key Messages
24 | 1. **End the State Management Wars** - Impartial expert on all approaches
25 | 2. **Beyond the README** - Full source analysis, not just documentation
26 | 3. **Always Current** - Real-time fetching, never outdated
27 |
28 | ### Launch Plan
29 | - **Platform**: r/FlutterDev "Show-off Saturday"
30 | - **Demo**: LLM failing → add @flutter_mcp → perfect answer
31 | - **Engagement**: Live package request fulfillment during launch
32 | - **Influencers**: Reach out to top Flutter YouTubers
33 |
34 | ### Viral Tactics
35 | - Developer testimonials with specific problems solved
36 | - "Powered by @flutter_mcp" badges
37 | - Community-generated before/after demos
38 | - Flutter package maintainer partnerships
39 |
40 | ## Success Metrics
41 | - 1,000+ GitHub stars in first month
42 | - 100+ packages indexed in first week
43 | - 50%+ cache hit rate after first month
44 | - 10+ developer testimonials
45 | - Coverage in Flutter Weekly
46 |
47 | ## Timeline
48 | - **MVP (4 hours)**: Basic server with Flutter API docs
49 | - **Week 1**: Add pub.dev support, search, polish
50 | - **Week 2**: Launch preparation and marketing push
51 | - **Launch Week**: Coordinated multi-platform release
52 |
53 | ## Files Created
54 | 1. `project-tasks.csv` - 60 detailed tasks with priorities
55 | 2. `ingestion-strategy.md` - What content to extract from packages
56 | 3. `context7-marketing-analysis.md` - Marketing tactics analysis
57 |
58 | The project is designed to solve a real problem (outdated AI knowledge of Flutter) with a simple solution (@flutter_mcp activation) that can be built quickly and marketed effectively to the Flutter community.

1 | # Flutter MCP vs Context7: Installation Simplicity Achieved! 🎉
2 |
3 | ## Installation Comparison
4 |
5 | ### Context7
6 | ```bash
7 | npx -y @upstash/context7-mcp
8 | ```
9 |
10 | ### Flutter MCP (After Improvements)
11 | ```bash
12 | pip install flutter-mcp-server
13 | flutter-mcp start
14 | ```
15 |
16 | Or even simpler with executables:
17 | ```bash
18 | # Download and run - no Python needed!
19 | curl -L https://github.com/flutter-mcp/releases/latest/flutter-mcp-macos -o flutter-mcp
20 | chmod +x flutter-mcp
21 | ./flutter-mcp
22 | ```
23 |
24 | ## What We Changed
25 |
26 | ### Phase 1: Removed External Dependencies ✅
27 | - **Before**: Required Python + Redis server
28 | - **After**: Just Python (SQLite built-in)
29 | - **Impact**: 50% reduction in setup complexity
30 |
31 | ### Phase 2: Single Executable Distribution ✅
32 | - **Before**: pip install + dependencies
33 | - **After**: Download one file and run
34 | - **Impact**: Zero dependencies for end users
35 |
36 | ## Key Improvements Made
37 |
38 | 1. **Replaced Redis with SQLite**
39 | - No external services to install/manage
40 | - Automatic cache directory creation
41 | - Platform-aware storage locations
42 | - Same performance for single-user tool
43 |
44 | 2. **Added PyInstaller Packaging**
45 | - Creates standalone executables
46 | - Bundles Python runtime
47 | - Works on Windows, macOS, Linux
48 | - ~30MB download vs multi-step install
49 |
50 | 3. **Simplified Configuration**
51 | - Removed all Redis configuration options
52 | - Works with zero config out of the box
53 | - Optional cache directory override only
54 |
55 | 4. **Multiple Distribution Options**
56 | - PyPI: `pip install flutter-mcp-server`
57 | - Docker: `docker run ghcr.io/flutter-mcp/flutter-mcp`
58 | - Executable: Download and run
59 | - Source: Clone and develop
60 |
61 | ## Performance Impact
62 |
63 | - **First query**: Same (1-2 seconds to fetch)
64 | - **Cached queries**: <50ms (SQLite nearly as fast as Redis)
65 | - **Startup time**: PyInstaller adds ~1 second (acceptable)
66 | - **Memory usage**: Slightly lower without Redis
67 |
68 | ## User Experience Wins
69 |
70 | 1. **Zero Configuration Required**
71 | - No Redis URLs
72 | - No service management
73 | - No port conflicts
74 |
75 | 2. **Works Everywhere**
76 | - macOS, Windows, Linux
77 | - No admin rights needed
78 | - Portable executables
79 |
80 | 3. **Graceful Degradation**
81 | - Cache automatically created
82 | - Works offline with cache
83 | - Clear error messages
84 |
85 | ## Conclusion
86 |
87 | Flutter MCP now matches Context7's installation simplicity while maintaining all functionality. Users can choose their preferred installation method:
88 |
89 | - **Developers**: `pip install` for easy updates
90 | - **Non-technical users**: Download executable
91 | - **Teams**: Docker for consistency
92 | - **Contributors**: Clone and develop
93 |
94 | The key insight from Context7: **Hide complexity, not functionality**. By replacing Redis with SQLite and adding executable distribution, we achieved the same "it just works" experience! 🚀

23 | "args": ["start"],
24 | "env": {}
25 | }
26 | }
27 | }
28 | ```
29 |
30 | Or using npx:
31 | ```json
32 | {
33 | "mcpServers": {
34 | "flutter-mcp": {
35 | "command": "npx",
36 | "args": ["@flutter-mcp/server", "start"],
37 | "env": {}
38 | }
39 | }
40 | }
41 | ```
42 |
43 | ## MCP SuperAssistant
44 |
45 | **Transport**: HTTP
46 |
47 | 1. Start the server:
48 | ```bash
49 | flutter-mcp start --transport http --port 8000
50 | ```
51 |
52 | 2. In MCP SuperAssistant:
53 | - Click "Add Server"
54 | - Name: `Flutter MCP`

61 |
62 | ### Global Configuration
63 |
64 | Install globally and Claude Code will auto-detect:
65 | ```bash
66 | pip install flutter-mcp-server
67 | ```
68 |
69 | ### Per-Project Configuration
70 |
71 | Create `.mcp.json` in your project root:
72 | ```json
73 | {
74 | "mcpServers": {
75 | "flutter-mcp": {
76 | "command": "/path/to/flutter-mcp/venv/bin/flutter-mcp",
77 | "args": ["start"]
78 | }
79 | }
80 | }
81 | ```
82 |
83 | ## VS Code + Continue
84 |
85 | **Transport**: STDIO
86 |
87 | In `.continuerc.json`:
88 | ```json
89 | {
90 | "models": [
91 | {
92 | "provider": "claude",
93 | "mcp_servers": {
94 | "flutter-mcp": {
95 | "command": "flutter-mcp",
96 | "args": ["start"]
97 | }
98 | }
99 | }
100 | ]
101 | }
102 | ```
103 |
104 | ## Custom HTTP Client
105 |
106 | **Transport**: HTTP
107 |
108 | ```python
109 | import httpx
110 |
111 | # Start server: flutter-mcp start --transport http --port 8000
112 |
113 | client = httpx.Client(base_url="http://localhost:8000")
114 |
115 | # Make MCP requests
116 | response = client.post("/mcp/v1/tools/list")
117 | tools = response.json()
118 |
119 | # Call a tool
120 | response = client.post("/mcp/v1/tools/call", json={
121 | "name": "get_flutter_docs",
122 | "arguments": {
123 | "query": "StatefulWidget"
124 | }
125 | })
126 | ```
127 |
128 | ## Custom SSE Client
129 |
130 | **Transport**: SSE
131 |
132 | ```javascript
133 | // Start server: flutter-mcp start --transport sse --port 8080
134 |
135 | const eventSource = new EventSource('http://localhost:8080/sse');
136 |
137 | eventSource.onmessage = (event) => {
138 | const data = JSON.parse(event.data);
139 | console.log('Received:', data);
140 | };
141 |
142 | // Send requests via POST to the same server
143 | fetch('http://localhost:8080/mcp/v1/tools/list', {
144 | method: 'POST',
145 | headers: { 'Content-Type': 'application/json' }
146 | })
147 | .then(res => res.json())
148 | .then(console.log);
149 | ```
150 |
151 | ## Docker Configurations

159 | "command": "docker",
160 | "args": [
161 | "run", "-i", "--rm",
162 | "ghcr.io/flutter-mcp/flutter-mcp:latest"
163 | ]
164 | }
165 | }
166 | }
167 | ```
168 |
169 | ### HTTP Server with Docker
170 |
171 | ```bash
172 | # Run with HTTP transport exposed
173 | docker run -p 8000:8000 ghcr.io/flutter-mcp/flutter-mcp:latest \
174 | flutter-mcp start --transport http --host 0.0.0.0 --port 8000
175 | ```
176 |
177 | ## Environment Variables
178 |
179 | All transport modes support these environment variables:
180 |
181 | ```bash
182 | # Cache directory
183 | export CACHE_DIR=/path/to/cache
184 |
185 | # Debug logging
186 | export DEBUG=1
187 |
188 | # Transport settings (when not using CLI args)
189 | export MCP_TRANSPORT=http
190 | export MCP_PORT=8000
191 | export MCP_HOST=0.0.0.0
192 | ```
193 |
194 | ## Troubleshooting Connection Issues
195 |
196 | ### STDIO Transport
197 | - Ensure the command path is correct
198 | - Check Python is installed: `python3 --version`
199 | - Verify installation: `flutter-mcp --version`
200 |
201 | ### HTTP/SSE Transport
202 | - Check port availability: `lsof -i :8000`
203 | - Try different port: `--port 8080`
204 | - Bind to all interfaces: `--host 0.0.0.0`
205 | - Check firewall settings
206 |
207 | ### Common Issues
208 |
209 | 1. **"Connection refused"**
210 | - Server not running
211 | - Wrong port
212 | - Firewall blocking connection
213 |
214 | 2. **"Command not found"**
215 | - Package not installed
216 | - Wrong path in configuration
217 | - Virtual environment not activated
218 |
219 | 3. **"Transport mismatch"**
220 | - Client expects different transport
221 | - Check client documentation
222 | - Use correct transport flag
223 |
224 | ## Testing Connection
225 |
226 | ### Test STDIO
227 | ```bash
228 | echo '{"method": "mcp/v1/tools/list"}' | flutter-mcp start
229 | ```
230 |
231 | ### Test HTTP
232 | ```bash
233 | # Start server
234 | flutter-mcp start --transport http --port 8000
235 |
236 | # Test with curl
237 | curl -X POST http://localhost:8000/mcp/v1/tools/list
238 | ```
239 |
240 | ### Test SSE
241 | ```bash
242 | # Start server
243 | flutter-mcp start --transport sse --port 8080
244 |
245 | # Test with curl
246 | curl http://localhost:8080/sse
247 | ```
```

1 | # Flutter MCP Server - Implementation Summary
2 |
3 | ## 🎯 Project Overview
4 |
5 | We've successfully built a complete Flutter MCP (Model Context Protocol) server that provides real-time Flutter/Dart documentation to AI assistants. The server supports ALL 50,000+ packages on pub.dev through on-demand fetching.
6 |
7 | ## ✅ Completed Features
8 |
9 | ### Core Functionality
10 | - ✅ **FastMCP Server**: Built with Python using the FastMCP framework
11 | - ✅ **5 MCP Tools**:
12 | - `get_flutter_docs` - Fetches Flutter/Dart API documentation
13 | - `get_pub_package_info` - Gets package info with full README from pub.dev
14 | - `search_flutter_docs` - Intelligent search across documentation
15 | - `process_flutter_mentions` - Parses @flutter_mcp mentions in text
16 | - `health_check` - Monitors scraper and service health
17 | - ✅ **Redis Caching**: 24h for APIs, 12h for packages with graceful fallback
18 | - ✅ **Rate Limiting**: 2 requests/second to respect server resources
19 | - ✅ **HTML to Markdown Converter**: Clean documentation for AI consumption
20 | - ✅ **Smart URL Resolution**: Pattern matching for Flutter/Dart libraries
21 |
22 | ### Developer Experience
23 | - ✅ **CLI Interface**: `flutter-mcp start/dev/help/version` commands
24 | - ✅ **Multiple Installation Options**:
25 | - PyPI: `pip install flutter-mcp-server`
26 | - Docker: `docker run ghcr.io/flutter-mcp/flutter-mcp`
27 | - Docker Compose with Redis included
28 | - ✅ **Works Without Redis**: Graceful degradation with warnings
29 | - ✅ **Structured Logging**: Using structlog for debugging
30 |
31 | ### Testing & Quality
32 | - ✅ **Integration Tests**: 80% pass rate (4/5 tests)
33 | - ✅ **Tested with Popular Packages**: provider, bloc, dio, get, riverpod
34 | - ✅ **Health Check System**: Real-time monitoring of scraper status
35 | - ✅ **Error Handling**: Graceful failures with helpful messages
36 |
37 | ### Documentation & Distribution
38 | - ✅ **Comprehensive README**: Quick start, features, tool reference
39 | - ✅ **CONTRIBUTING.md**: Community guidelines and development setup

1 | # Token Management Implementation Plan
2 |
3 | ## Overview
4 |
5 | This document outlines the implementation of token management for Flutter MCP, inspired by Context7's simple approach but adapted for our client-side architecture.
6 |
7 | ## Goals
8 |
9 | 1. **Simple API**: Add optional `tokens` parameter to all documentation tools
10 | 2. **Smart Truncation**: Preserve most important content when limits are reached
11 | 3. **Performance**: Fast token counting without impacting response times
12 | 4. **Transparency**: Clear indication when content is truncated
13 | 5. **Context7-like UX**: Sensible defaults, no required parameters
14 |
15 | ## Implementation Phases
16 |
17 | ### Phase 1: Basic Token Management (Status: In Progress)
18 | - [ ] Add `tokens` parameter to all documentation tools
19 | - [ ] Implement basic token counting (word-based approximation)
20 | - [ ] Simple truncation at section boundaries
21 | - [ ] Update response format with token metadata
22 |
23 | ### Phase 2: Smart Truncation (Status: Pending)
24 | - [ ] Create priority-based content classification
25 | - [ ] Implement Flutter-aware section detection
26 | - [ ] Add intelligent truncation algorithm
27 | - [ ] Preserve markdown formatting during truncation
28 |
29 | ### Phase 3: Cache Integration (Status: Pending)
30 | - [ ] Update cache schema to store token counts
31 | - [ ] Modify cache read/write operations
32 | - [ ] Ensure backward compatibility with existing cache
33 |
34 | ### Phase 4: Testing & Documentation (Status: Pending)
35 | - [ ] Unit tests for token counting
36 | - [ ] Integration tests for truncation
37 | - [ ] Update API documentation
38 | - [ ] Add usage examples
39 |
40 | ## Technical Design
41 |
42 | ### Token Counting Strategy
43 |
44 | **Approximation Method** (Default):
45 | ```python
46 | def approximate_tokens(text: str) -> int:
47 | """Fast token approximation: ~1.3 tokens per word"""
48 | return int(len(text.split()) * 1.3)
49 | ```
50 |
51 | **Accurate Counting** (Optional):
52 | - Use tiktoken for GPT models
53 | - Lazy-loaded to avoid startup overhead
54 | - Configurable via environment variable
55 |
56 | ### Default Token Limits
57 |
58 | | Tool | Default | Minimum | Rationale |
59 | |------|---------|---------|-----------|
60 | | get_flutter_docs | 8,000 | 1,000 | Single class documentation |
61 | | search_flutter_docs | 5,000 | 1,000 | Multiple search results |
62 | | get_pub_package_info | 6,000 | 1,000 | Package info + README |
63 | | process_flutter_mentions | 4,000 | 500 | Per mention |
64 |
65 | ### Truncation Priority
66 |
67 | 1. **CRITICAL**: Class description, constructor signatures
68 | 2. **HIGH**: Common methods (build, setState), essential properties
69 | 3. **MEDIUM**: Secondary methods, code examples
70 | 4. **LOW**: Inherited members, see also sections
71 | 5. **MINIMAL**: Related classes, external links
72 |
73 | ### Response Format
74 |
75 | ```json
76 | {
77 | "content": "# Widget Name\n...",
78 | "source": "live|cache",
79 | "truncated": true,
80 | "token_count": 2000,
81 | "original_tokens": 5234,
82 | "sections_included": ["description", "constructors"],
83 | "sections_truncated": ["methods", "examples"],
84 | "truncation_note": "Documentation limited to 2000 tokens."
85 | }
86 | ```
87 |
88 | ## Implementation Progress
89 |
90 | ### ✅ Completed
91 | - Created implementation plan document

110 | - Fast word-based approximation (default)
111 | - Optional accurate counting with tiktoken
112 | - Environment variable configuration
113 | - ~1.3 tokens per word ratio
114 |
115 | 2. **DocumentTruncator** (`src/flutter_mcp/truncation.py`)
116 | - Smart section detection for Flutter docs
117 | - Priority-based content preservation
118 | - Maintains markdown formatting
119 | - Graceful degradation for edge cases
120 |
121 | 3. **Server Integration**
122 | - All tools now accept optional `tokens` parameter
123 | - Automatic truncation when limits exceeded
124 | - Token metadata in all responses
125 | - Transparent to existing users (backward compatible)
126 |
127 | 4. **Cache Enhancement**
128 | - Stores token counts with content
129 | - Avoids re-counting for cached docs
130 | - Schema migration for existing databases
131 | - Statistics tracking for cached tokens
132 |
133 | 5. **Testing & Documentation**
134 | - Comprehensive test suite
135 | - Interactive demo script
136 | - Usage examples
137 |
138 | ### Key Features
139 |

141 | - **Fast**: Approximation takes <1ms for typical docs
142 | - **Smart**: Preserves most important content when truncating
143 | - **Transparent**: Users see token counts and truncation status
144 | - **Cached**: Token counts stored to avoid recalculation
145 |
146 | ### Usage
147 |
148 | ```python
149 | # Default usage - no change needed
150 | docs = await get_flutter_docs("Container")
151 |
152 | # With token limit
153 | docs = await get_flutter_docs("Container", tokens=2000)
154 |
155 | # Response includes token info
156 | {
157 | "content": "...",
158 | "token_count": 1998,
159 | "truncated": true,
160 | "truncation_note": "Documentation limited to 2000 tokens."
161 | }
162 | ```
163 |
164 | ## Notes
165 |
166 | - Using word-based approximation for performance (1.3 tokens/word)
167 | - Optional tiktoken integration for accuracy
168 | - Cache stores both content and token count
169 | - Backward compatible with existing cache entries

1 | # Flutter MCP Server Project - Complete Summary
2 |
3 | ## Background: MCP Server Configuration Journey
4 |
5 | ### Initial Setup - Three Main MCP Servers
6 |
7 | 1. **Firebase MCP** (Account-wide access)
8 | - Official Firebase CLI MCP server
9 | - Access to all Firebase projects
10 | - No `--dir` flag for unscoped access
11 | - Authentication via `firebase login`
12 |
13 | 2. **Supabase MCP** (Account-wide access)
14 | - Uses Personal Access Token (NOT project API keys)
15 | - Token from Account Settings → Access Tokens
16 | - `--read-only` flag recommended for safety
17 | - Access to all Supabase projects without `--project-ref`
18 |
19 | 3. **ZEN MCP Server**
20 | - Docker-based multi-AI orchestration
21 | - Connects Claude with Gemini, O3, GPT-4o
22 | - Enables AI-to-AI conversations
23 | - Already running as Docker container
24 |
25 | ### Configuration Files
26 |
27 | **Claude Desktop** (`~/Library/Application Support/Claude/claude_desktop_config.json`):
28 | ```json
29 | {
30 | "mcpServers": {
31 | "firebase-all": {
32 | "command": "npx",
33 | "args": ["-y", "firebase-tools@latest", "experimental:mcp"]
34 | },
35 | "supabase-all": {
36 | "command": "npx",
37 | "args": [
38 | "-y",
39 | "@supabase/mcp-server-supabase@latest",
40 | "--read-only"
41 | ],
42 | "env": {
43 | "SUPABASE_ACCESS_TOKEN": "sbp_YOUR_TOKEN_HERE"
44 | }
45 | },
46 | "zen": {
47 | "command": "docker",
48 | "args": [
49 | "exec",
50 | "-i",
51 | "zen-mcp-server",
52 | "python",
53 | "server.py"
54 | ]
55 | }
56 | }
57 | }
58 | ```
59 |
60 | **Claude Code** (stored in `~/.claude.json`):
61 | ```bash
62 | # Add globally with user scope
63 | claude mcp add firebase-global -s user -- npx -y firebase-tools@latest experimental:mcp
64 | claude mcp add supabase-global -s user -e SUPABASE_ACCESS_TOKEN=your_token -- npx -y @supabase/mcp-server-supabase@latest --read-only
65 | claude mcp add zen -s user -- docker exec -i zen-mcp-server python server.py
66 | ```
67 |
68 | ## Context7 and Deepwiki Research
69 |
70 | ### Context7 (by Upstash)
71 | - **Purpose**: Real-time library documentation
72 | - **Problem Solved**: Outdated API information in LLMs
73 | - **Coverage**: 50+ JavaScript/Python libraries
74 | - **Key Feature**: Dynamic documentation fetching
75 | - **Cost**: Completely FREE, no API keys needed
76 | - **Usage**: Add "use context7" to prompts
77 | - **Architecture**: Local Node.js execution
78 |
79 | ### Deepwiki (by Cognition Labs)
80 | - **Purpose**: GitHub repository understanding
81 | - **Problem Solved**: Quick codebase comprehension
82 | - **Coverage**: 50,000+ indexed repositories
83 | - **Key Feature**: AI-analyzed repository documentation
84 | - **Cost**: Free for public repos
85 | - **Architecture**: Remote SSE server
86 |
87 | ### Why They Don't Work for Flutter
88 | - Context7: Only supports JavaScript/Python libraries
89 | - Deepwiki: Works for Flutter repos but doesn't understand Dart/Flutter APIs specifically
90 |
91 | ## Flutter MCP Server Project Plan
92 |
93 | ### Vision
94 | Create a Context7-like MCP server specifically for Flutter/Dart ecosystem that provides:
95 | - Real-time Flutter/Dart API documentation
96 | - Pub.dev package documentation on-demand
97 | - Flutter cookbook and samples
98 | - Stack Overflow Flutter solutions
99 |
100 | ### Technical Decisions
101 |
102 | 1. **Inspiration**: Context7's approach (real-time docs > static knowledge)
103 | 2. **Language**: Python (easier for Claude Code to write)
104 | 3. **Architecture**: On-demand fetching (better for marketing "supports ALL pub.dev packages")
105 | 4. **Distribution**: Public GitHub/npm package
106 |
107 | ### Data Sources to Integrate
108 | - **Official APIs**: api.flutter.dev, api.dart.dev
109 | - **Package Registry**: pub.dev (on-demand fetching)
110 | - **Examples**: Flutter cookbook, official samples
111 | - **Community**: Stack Overflow Flutter tags
112 |
113 | ### MVP Scope
114 | - Start with official Flutter/Dart API documentation only
115 | - Estimated time: 2-4 hours with Claude Code
116 | - Focus on working prototype first
117 |

/docs/VERSION_SPECIFICATION.md:
--------------------------------------------------------------------------------
```markdown
1 | # Version Specification System
2 |
3 | The Flutter MCP server now supports advanced version specifications for pub.dev packages, allowing AI assistants to fetch documentation for specific package versions based on various constraint formats.
4 |
5 | ## Overview
6 |
7 | When referencing packages with `@flutter_mcp`, you can now specify version constraints similar to how they work in `pubspec.yaml` files. This ensures AI assistants get documentation that matches the exact version requirements of a project.
8 |
9 | ## Supported Formats
10 |
11 | ### 1. Exact Versions
12 |
13 | Specify an exact version to fetch documentation for that specific release:
14 |
15 | ```
16 | @flutter_mcp riverpod:2.5.1
17 | @flutter_mcp provider:6.0.5
18 | @flutter_mcp dio:5.3.2
19 | ```
20 |
21 | ### 2. Caret Syntax (^)
22 |
23 | The caret syntax allows compatible updates according to semantic versioning:
24 |
25 | ```
26 | @flutter_mcp provider:^6.0.0 # Allows >=6.0.0 <7.0.0
27 | @flutter_mcp bloc:^8.1.0 # Allows >=8.1.0 <9.0.0
28 | @flutter_mcp get:^4.6.5 # Allows >=4.6.5 <5.0.0
29 | ```
30 |
31 | For packages with 0.x.x versions, the caret is more restrictive:
32 | - `^0.2.3` allows `>=0.2.3 <0.3.0`
33 | - `^0.0.3` allows `>=0.0.3 <0.0.4`
34 |
35 | ### 3. Version Ranges
36 |
37 | Specify explicit version ranges using comparison operators:
38 |
39 | ```
40 | @flutter_mcp dio:>=5.0.0 <6.0.0 # Any 5.x version
41 | @flutter_mcp http:>0.13.0 <=1.0.0 # Greater than 0.13.0, up to and including 1.0.0
42 | @flutter_mcp provider:>=6.0.0 # 6.0.0 or higher
43 | @flutter_mcp bloc:<9.0.0 # Any version below 9.0.0
44 | ```
45 |
46 | ### 4. Special Keywords
47 |
48 | Use keywords to fetch specific version types:
49 |
50 | ```
51 | @flutter_mcp provider:latest # Absolute latest version (including pre-releases)
52 | @flutter_mcp riverpod:stable # Latest stable version (no pre-releases)
53 | @flutter_mcp bloc:dev # Latest dev version
54 | @flutter_mcp get:beta # Latest beta version
55 | @flutter_mcp dio:alpha # Latest alpha version
56 | ```
57 |
58 | ### 5. No Version (Current Behavior)
59 |
60 | When no version is specified, the system fetches the latest stable version:
61 |
62 | ```
63 | @flutter_mcp provider # Latest stable version
64 | @flutter_mcp riverpod # Latest stable version
65 | ```
66 |
67 | ## Examples in Context
68 |
69 | ### Example 1: Upgrading Dependencies
70 |
71 | ```
72 | I'm upgrading from @flutter_mcp provider:^5.0.0 to @flutter_mcp provider:^6.0.0.
73 | What are the breaking changes I need to be aware of?
74 | ```
75 |
76 | ### Example 2: Testing Pre-release Features
77 |
78 | ```
79 | I want to try the new features in @flutter_mcp riverpod:beta.
80 | Can you show me what's new compared to @flutter_mcp riverpod:stable?
81 | ```
82 |
83 | ### Example 3: Version Compatibility
84 |
85 | ```
86 | My project uses @flutter_mcp dio:>=5.0.0 <6.0.0 for networking.
87 | Is this compatible with @flutter_mcp retrofit:^4.0.0?
88 | ```
89 |
90 | ### Example 4: Legacy Code
91 |
92 | ```
93 | I'm maintaining legacy code that uses @flutter_mcp provider:5.0.0.
94 | Can you help me understand the API from that specific version?
95 | ```
96 |
97 | ## How It Works
98 |
99 | ### Version Resolution
100 |
101 | 1. **Parsing**: The system parses the version specification to understand the constraint type
102 | 2. **Resolution**: For constraints (not exact versions), the system queries pub.dev to find all available versions
103 | 3. **Selection**: The highest version that satisfies the constraint is selected
104 | 4. **Fetching**: Documentation for the selected version is retrieved and cached
105 |
106 | ### Caching
107 |
108 | Version-specific documentation is cached separately:
109 | - Cache key includes the package name and resolved version
110 | - Different version constraints that resolve to the same version share the cache
111 | - Cache duration: 12 hours for package documentation
112 |
113 | ### Error Handling
114 |
115 | The system provides helpful error messages:
116 | - If a version doesn't exist: Lists available versions
117 | - If constraint can't be resolved: Explains why
118 | - If package doesn't exist: Standard package not found error
119 |
120 | ## Implementation Details
121 |
122 | ### Version Parser
123 |
124 | The `VersionParser` class handles parsing of version specifications:
125 | - Regex patterns for different constraint formats
126 | - Semantic version comparison logic
127 | - Support for pre-release versions
128 |
129 | ### Version Resolver
130 |
131 | The `VersionResolver` class interfaces with pub.dev API:
132 | - Fetches available versions from pub.dev
133 | - Applies constraint logic to find best match
134 | - Handles special keywords (latest, stable, etc.)
135 |
136 | ### Integration
137 |
138 | The version system is fully integrated with:
139 | - `process_flutter_mentions`: Parses mentions with version specs
140 | - `get_pub_package_info`: Fetches version-specific documentation
141 | - Cache system: Version-aware cache keys
142 |
143 | ## Best Practices
144 |
145 | 1. **Use Caret for Flexibility**: `^` allows compatible updates
146 | ```
147 | @flutter_mcp provider:^6.0.0
148 | ```
149 |
150 | 2. **Exact Versions for Reproducibility**: When you need specific behavior
151 | ```
152 | @flutter_mcp riverpod:2.5.1
153 | ```
154 |
155 | 3. **Ranges for Compatibility**: When working with multiple packages
156 | ```
157 | @flutter_mcp dio:>=5.0.0 <6.0.0
158 | ```
159 |
160 | 4. **Keywords for Exploration**: Testing new features
161 | ```
162 | @flutter_mcp bloc:beta
163 | ```
164 |
165 | ## Limitations
166 |
167 | 1. **Flutter/Dart Classes**: Version specifications only work with pub.dev packages, not Flutter framework classes
168 | - ✅ `@flutter_mcp provider:^6.0.0`
169 | - ❌ `@flutter_mcp material.AppBar:^3.0.0`
170 |
171 | 2. **Version Availability**: Only versions published on pub.dev are accessible
172 |
173 | 3. **Rate Limiting**: Version resolution requires additional API calls, subject to rate limits
174 |
175 | ## Future Enhancements
176 |
177 | Potential future improvements:
178 | 1. Flutter SDK version-specific documentation
179 | 2. Git commit/branch references for packages
180 | 3. Local path references for development
181 | 4. Version comparison tools
182 | 5. Migration guide generation between versions

1 | # Flutter MCP Server - Error Handling & Resilience
2 |
3 | This document describes the comprehensive error handling and resilience features implemented in the Flutter MCP Server.
4 |
5 | ## Overview
6 |
7 | The Flutter MCP Server is designed to be highly resilient and provide a good user experience even when external services are unavailable or experiencing issues. The server implements multiple layers of error handling, retry logic, and graceful degradation.
8 |
9 | ## Error Handling Features
10 |
11 | ### 1. Retry Logic with Exponential Backoff
12 |
13 | All HTTP requests implement automatic retry with exponential backoff:
14 |
15 | - **Max retries**: 3 attempts
16 | - **Base delay**: 1 second
17 | - **Max delay**: 16 seconds
18 | - **Jitter**: Random 0-1 second added to prevent thundering herd
19 | - **Smart retries**: Only retries on network errors and 5xx server errors, not 4xx client errors
20 |
21 | ```python
22 | @with_retry(max_retries=3)
23 | async def fetch_data():
24 | # Automatic retry on network failures
25 | pass
26 | ```
27 |
28 | ### 2. Comprehensive Error Types
29 |
30 | The server categorizes errors for better handling:
31 |
32 | - `NetworkError`: Connection failures, timeouts
33 | - `DocumentationNotFoundError`: Resource not found (404)
34 | - `RateLimitError`: Rate limit exceeded (429)
35 | - `CacheError`: Cache operation failures
36 |
37 | ### 3. User-Friendly Error Responses
38 |
39 | All errors return structured responses with:
40 |
41 | ```json
42 | {
43 | "error": true,
44 | "error_type": "not_found",
45 | "message": "Documentation not found for widgets.NonExistentWidget",
46 | "suggestions": [
47 | "Check if 'NonExistentWidget' is spelled correctly",
48 | "Verify that 'NonExistentWidget' exists in the 'widgets' library",
49 | "Common libraries: widgets, material, cupertino, painting, rendering",
50 | "Try searching with: search_flutter_docs('NonExistentWidget')"
51 | ],
52 | "context": {
53 | "class": "NonExistentWidget",
54 | "library": "widgets",
55 | "status_code": 404
56 | },
57 | "timestamp": "2024-01-20T10:30:00Z"
58 | }
59 | ```
60 |
61 | ### 4. Circuit Breaker Pattern
62 |
63 | Prevents cascading failures when external services are down:
64 |
65 | - **Failure threshold**: 5 consecutive failures
66 | - **Recovery timeout**: 60 seconds
67 | - **States**: CLOSED (normal), OPEN (failing), HALF-OPEN (testing)
68 |
69 | ```python
70 | flutter_docs_circuit = CircuitBreaker(
71 | failure_threshold=5,
72 | recovery_timeout=60.0
73 | )
74 | ```
75 |
76 | ### 5. Graceful Degradation
77 |
78 | The server continues operating even when some components fail:
79 |
80 | - **Cache failures**: Continue without caching
81 | - **README fetch failures**: Return package info without README
82 | - **Enrichment failures**: Return search results without full documentation
83 |
84 | ### 6. Health Monitoring
85 |
86 | Comprehensive health check system:
87 |
88 | ```python
89 | # Health check with timeout protection
90 | async def health_check():
91 | # Tests Flutter docs API
92 | # Tests pub.dev API
93 | # Tests cache functionality
94 | # Returns detailed status for each component
95 | ```
96 |
97 | ### 7. Timeout Protection
98 |
99 | All operations have configurable timeouts:
100 |
101 | - **Default timeout**: 30 seconds
102 | - **Connection timeout**: 10 seconds
103 | - **Health check timeout**: 10 seconds
104 |
105 | ### 8. Rate Limiting
106 |
107 | Respectful rate limiting for external APIs:
108 |
109 | - **Default rate**: 2 requests/second
110 | - **Adjustable during high load**
111 | - **Per-service rate limiters**
112 |
113 | ## Error Scenarios Handled
114 |
115 | ### Network Errors
116 |
117 | - Connection timeouts
118 | - DNS resolution failures
119 | - Connection refused
120 | - Network unreachable
121 |
122 | **User Experience**: Clear message about network issues with retry suggestions
123 |
124 | ### API Errors
125 |
126 | - 404 Not Found: Helpful suggestions for correct names/formats
127 | - 429 Rate Limited: Advises waiting and provides retry timing
128 | - 500-599 Server Errors: Indicates external service issues
129 | - Invalid responses: Handles malformed JSON/HTML
130 |
131 | ### Input Validation
132 |
133 | - Invalid class names
134 | - Invalid package names (must be lowercase with underscores)
135 | - Malformed queries
136 | - Empty inputs
137 |
138 | ### Cache Errors
139 |
140 | - Cache initialization failures: Falls back to no-cache mode
141 | - Cache read/write errors: Logged but don't fail requests
142 | - Corrupted cache entries: Automatic cleanup
143 |
144 | ## Testing Error Handling
145 |
146 | Run the error handling test suite:
147 |
148 | ```bash
149 | python test_error_handling.py
150 | ```
151 |
152 | This tests:
153 | 1. Invalid Flutter class names
154 | 2. Invalid library names
155 | 3. Non-existent packages
156 | 4. Invalid package name formats
157 | 5. Search with no results
158 | 6. Mention processing with errors
159 | 7. Health check functionality
160 | 8. Graceful degradation
161 |
162 | ## Logging
163 |
164 | Structured logging with contextual information:
165 |
166 | ```python
167 | logger.error(
168 | "http_error",
169 | status_code=404,
170 | url="https://api.flutter.dev/...",
171 | class_name="NonExistentWidget",
172 | library="widgets"
173 | )
174 | ```
175 |
176 | ## Recovery Mechanisms
177 |
178 | ### Automatic Recovery
179 |
180 | 1. **Cache clearing**: After 3 consecutive failures
181 | 2. **Connection pool reset**: After 5 consecutive failures
182 | 3. **Rate limit reduction**: After 7 consecutive failures
183 |
184 | ### Manual Recovery
185 |
186 | - Restart server to reset all circuit breakers
187 | - Clear cache directory to remove corrupted data
188 | - Check logs for specific error patterns
189 |
190 | ## Best Practices
191 |
192 | 1. **Always check for errors** in responses:
193 | ```python
194 | result = await get_flutter_docs("Widget", "widgets")
195 | if result.get("error"):
196 | # Handle error
197 | ```
198 |
199 | 2. **Use suggestions** provided in error responses
200 | 3. **Implement backoff** when seeing rate limit errors
201 | 4. **Monitor health endpoint** for service status
202 |
203 | ## Configuration
204 |
205 | Error handling can be configured via environment variables:
206 |
207 | ```bash
208 | # Retry configuration
209 | MAX_RETRIES=3
210 | BASE_RETRY_DELAY=1.0
211 | MAX_RETRY_DELAY=16.0
212 |
213 | # Timeout configuration
214 | DEFAULT_TIMEOUT=30.0
215 | CONNECTION_TIMEOUT=10.0
216 |
217 | # Circuit breaker
218 | FAILURE_THRESHOLD=5
219 | RECOVERY_TIMEOUT=60.0
220 |
221 | # Rate limiting
222 | REQUESTS_PER_SECOND=2.0
223 | ```
224 |
225 | ## Monitoring
226 |
227 | Monitor these metrics for service health:
228 |
229 | - Error rates by type
230 | - Circuit breaker state changes
231 | - Cache hit/miss rates
232 | - Response times
233 | - Retry counts
234 |
235 | ## Future Improvements
236 |
237 | - [ ] Implement request queuing during rate limits
238 | - [ ] Add fallback to cached documentation during outages
239 | - [ ] Implement progressive retry delays based on error type
240 | - [ ] Add webhook notifications for circuit breaker state changes
241 | - [ ] Implement request deduplication

1 | # Smart Truncation Algorithm for Flutter/Dart Documentation
2 |
3 | ## Overview
4 |
5 | The smart truncation algorithm is designed to intelligently reduce Flutter and Dart documentation to fit within token limits while preserving the most critical information for developers. This algorithm uses a priority-based system to ensure that essential information is retained even under severe token constraints.
6 |
7 | ## Key Features
8 |
9 | ### 1. Priority-Based Content Classification
10 |
11 | The algorithm classifies documentation content into five priority levels:
12 |
13 | - **CRITICAL (1)**: Must always be retained
14 | - Class descriptions
15 | - Constructor signatures
16 |
17 | - **HIGH (2)**: Retained whenever possible
18 | - Primary method signatures (build, createState, initState, dispose)
19 | - Common properties (child, children, padding, margin, etc.)
20 | - Constructor descriptions
21 |
22 | - **MEDIUM (3)**: Retained if space allows
23 | - Secondary methods
24 | - Less common properties
25 | - First 2 code examples
26 |
27 | - **LOW (4)**: First to be removed
28 | - Private methods
29 | - Verbose method descriptions
30 | - Additional code examples (3+)
31 |
32 | - **MINIMAL (5)**: Removed first
33 | - Inherited members
34 | - See also sections
35 | - Related classes
36 |
37 | ### 2. Intelligent Section Parsing
38 |
39 | The algorithm parses Flutter documentation into semantic sections:
40 |
41 | ```python
42 | sections = [
43 | "description", # Class overview
44 | "constructors", # Constructor signatures and docs
45 | "properties", # Widget properties
46 | "methods", # Class methods
47 | "examples" # Code examples
48 | ]
49 | ```
50 |
51 | Each section is further broken down into sub-components with individual priorities.
52 |
53 | ### 3. Flutter-Aware Prioritization
54 |
55 | The algorithm has built-in knowledge of Flutter's widget hierarchy and common patterns:
56 |
57 | #### High-Priority Widgets
58 | ```python
59 | HIGH_PRIORITY_WIDGETS = {
60 | "Container", "Row", "Column", "Text", "Image", "Scaffold",
61 | "AppBar", "ListView", "GridView", "Stack", "Positioned",
62 | "Center", "Padding", "SizedBox", "Expanded", "Flexible",
63 | # ... and more
64 | }
65 | ```
66 |
67 | #### High-Priority Methods
68 | ```python
69 | HIGH_PRIORITY_METHODS = {
70 | "build", "createState", "initState", "dispose", "setState",
71 | "didChangeDependencies", "didUpdateWidget", "deactivate"
72 | }
73 | ```
74 |
75 | #### High-Priority Properties
76 | ```python
77 | HIGH_PRIORITY_PROPERTIES = {
78 | "child", "children", "width", "height", "color", "padding",
79 | "margin", "alignment", "decoration", "style", "onPressed",
80 | "onTap", "controller", "value", "enabled", "visible"
81 | }
82 | ```
83 |
84 | ### 4. Truncation Strategies
85 |
86 | The algorithm supports multiple truncation strategies:
87 |
88 | #### Balanced (Default)
89 | Maintains a good mix of all documentation types:
90 | - Keeps description, main constructors, key properties, and primary methods
91 | - Includes 1-2 code examples if space allows
92 | - Best for general-purpose documentation
93 |
94 | #### Signatures
95 | Prioritizes method and constructor signatures:
96 | - Maximizes retention of code signatures
97 | - Reduces or removes descriptions
98 | - Ideal when the user needs API reference information
99 |
100 | #### Examples
101 | Prioritizes code examples:
102 | - Keeps more code examples than other strategies
103 | - Useful for learning and implementation guidance
104 |
105 | #### Minimal
106 | Keeps only the most essential information:
107 | - Class description
108 | - Primary constructor
109 | - build() method for widgets
110 | - child/children properties
111 |
112 | ### 5. Smart Code Truncation
113 |
114 | When truncating code blocks, the algorithm:
115 | - Preserves syntactic validity when possible
116 | - Balances braces and brackets
117 | - Truncates at line boundaries
118 | - Adds ellipsis comments to indicate truncation
119 |
120 | Example:
121 | ```dart
122 | Container(
123 | width: 200,
124 | height: 200,
125 | child: Column(
126 | children: [
127 | Text('Line 1'),
128 | // ...
129 | ],
130 | ),
131 | )
132 | ```
133 |
134 | ### 6. Progressive Truncation
135 |
136 | The algorithm applies truncation progressively:
137 |
138 | 1. Calculate total token count
139 | 2. If under limit, return unchanged
140 | 3. Remove MINIMAL priority content
141 | 4. Remove LOW priority content
142 | 5. Reduce MEDIUM priority content
143 | 6. Trim HIGH priority content (descriptions only)
144 | 7. CRITICAL content is never removed
145 |
146 | ## Usage Examples
147 |
148 | ### Basic Usage
149 |
150 | ```python
151 | from flutter_mcp.truncation import truncate_flutter_docs
152 |
153 | # Truncate to 4000 tokens with balanced strategy
154 | truncated_doc = truncate_flutter_docs(
155 | content=original_documentation,
156 | class_name="Container",
157 | max_tokens=4000,
158 | strategy="balanced"
159 | )
160 | ```
161 |
162 | ### Advanced Usage with Metadata
163 |
164 | ```python
165 | from flutter_mcp.truncation import AdaptiveTruncator
166 |
167 | truncator = AdaptiveTruncator(max_tokens=2000)
168 | truncated_doc, metadata = truncator.truncate_with_strategy(
169 | doc_content=original_documentation,
170 | class_name="ListView",
171 | library="widgets",
172 | strategy="signatures"
173 | )
174 |
175 | print(f"Compression ratio: {metadata['compression_ratio']:.1%}")
176 | print(f"Was truncated: {metadata['was_truncated']}")
177 | ```
178 |
179 | ### Integration with MCP Server
180 |
181 | ```python
182 | # In the MCP tool
183 | @mcp.tool()
184 | async def get_flutter_docs(
185 | class_name: str,
186 | library: str = "widgets",
187 | max_tokens: int = None # Optional truncation
188 | ) -> Dict[str, Any]:
189 | # Fetch documentation...
190 |
191 | # Apply smart truncation if requested
192 | if max_tokens:
193 | content = truncate_flutter_docs(
194 | content,
195 | class_name,
196 | max_tokens=max_tokens,
197 | strategy="balanced"
198 | )
199 | ```
200 |
201 | ## Token Limits and Recommendations
202 |
203 | | Use Case | Recommended Token Limit | Strategy |
204 | |----------|------------------------|----------|
205 | | Quick reference | 500-1000 | minimal |
206 | | API overview | 2000-4000 | signatures |
207 | | Learning/Tutorial | 4000-8000 | examples |
208 | | Full documentation | 8000+ | balanced |
209 |
210 | ## Implementation Details
211 |
212 | ### Token Estimation
213 |
214 | The algorithm uses a simple but effective token estimation:
215 | - English text: ~4 characters per token
216 | - Code: ~3 characters per token
217 |
218 | This provides a good approximation for planning truncation without requiring actual tokenization.
219 |
220 | ### Section Preservation
221 |
222 | When a section must be truncated:
223 | 1. Code sections are truncated at line boundaries
224 | 2. Text sections are truncated at sentence boundaries
225 | 3. Lists are truncated at item boundaries
226 | 4. A truncation notice is always added
227 |
228 | ### Example Output
229 |
230 | Original documentation: 15,000 characters (~3,750 tokens)
231 | Truncated to 1,000 tokens:
232 |
233 | ```markdown
234 | # Container (Truncated Documentation)
235 |
236 | ## Description
237 | A convenience widget that combines common painting, positioning, and sizing widgets.
238 |
239 | ## Constructors
240 | ### Container({Key? key, AlignmentGeometry? alignment, ...})
241 | ```dart
242 | Container({
243 | Key? key,
244 | this.alignment,
245 | this.padding,
246 | this.color,
247 | this.decoration,
248 | double? width,
249 | double? height,
250 | this.child,
251 | })
252 | ```
253 |
254 | ## Properties
255 | - **child**: The child contained by the container
256 | - **padding**: Empty space to inscribe inside the decoration
257 | - **color**: The color to paint behind the child
258 | - **width**: Container width constraint
259 | - **height**: Container height constraint
260 |
261 | ## Methods
262 | ### build(BuildContext context)
263 | ```dart
264 | @override
265 | Widget build(BuildContext context) {
266 | // ... (truncated)
267 | }
268 | ```
269 |

271 | *Note: This documentation has been intelligently truncated to fit within token limits. Some sections may have been removed or shortened.*
272 | ```
273 |
274 | ## Performance Considerations
275 |
276 | The truncation algorithm is designed to be efficient:
277 | - O(n) parsing of documentation
278 | - O(n log n) sorting of sections by priority
279 | - O(n) reconstruction of truncated documentation
280 |
281 | Typical truncation takes <50ms for large documents.
282 |
283 | ## Future Enhancements
284 |
285 | Potential improvements to the algorithm:
286 |
287 | 1. **ML-based importance scoring**: Use machine learning to determine section importance based on usage patterns
288 | 2. **Context-aware truncation**: Adjust priorities based on the user's query context
289 | 3. **Cross-reference preservation**: Maintain links between related classes when truncating
290 | 4. **Incremental loading**: Support progressive disclosure of truncated content
291 | 5. **Custom priority profiles**: Allow users to define their own priority preferences
292 |
293 | ## Conclusion
294 |
295 | The smart truncation algorithm ensures that Flutter/Dart documentation remains useful even under severe token constraints. By understanding the structure and importance of different documentation sections, it preserves the most critical information while gracefully degrading less essential content.
