9 | ## 😫 The Pain
10 |
11 | Installing most MCPs feels like being thrown back to the 1990s:
12 |
13 | **The Typical MCP Installation:**
14 |
15 | ```bash
16 | # Step 1: Read the README (5 minutes)
17 | "Install via npm..."
18 | "Requires Node.js 18+"
19 | "Add to your config file..."
20 |
21 | # Step 2: Check if you have Node.js
22 | node --version
23 | # ERROR: command not found
24 | # [Ugh, need to install Node.js first]
25 |
26 | # Step 3: Install Node.js (15 minutes)
27 | [Download from nodejs.org]
28 | [Run installer]
29 | [Restart terminal]
30 | [Cross fingers]
31 |
32 | # Step 4: Install the MCP package
33 | npm install -g @modelcontextprotocol/server-filesystem
34 | # [Wait for npm to download dependencies]
35 | # [Wonder if it worked]
36 |
37 | # Step 5: Edit JSON config file (10 minutes)
38 | nano ~/Library/Application\ Support/Claude/claude_desktop_config.json
39 | # [Try to remember JSON syntax]
40 | # [Add MCP config]
41 | # [Break JSON with missing comma]
42 | # [Fix syntax error]
43 | # [Save and exit]
44 |
45 | # Step 6: Restart Claude Desktop
46 | # [Wait to see if it worked]
47 |
48 | # Step 7: Debug when it doesn't work
49 | # [Check logs]
50 | # [Google error message]
51 | # [Repeat steps 4-6]
52 |
53 | Total time: 45 minutes (if you're lucky)
54 | ```
55 |
56 | **For non-developers:** This is terrifying. Terminal commands? JSON editing? Node.js versions?
57 |
58 | **For developers:** This is annoying. Why can't it just... work?
59 |
60 | ---
61 |
62 | ## 📦 The Journey
63 |
64 | NCP via .mcpb makes installation feel like installing any app:
65 |
66 | ### **The Complete Installation Process:**
67 |
68 | **Step 1:** Go to [github.com/portel-dev/ncp/releases/latest](https://github.com/portel-dev/ncp/releases/latest)
69 |
70 | **Step 2:** Click "ncp.mcpb" to download
71 |
72 | **Step 3:** Double-click the downloaded file
73 |
74 | **Step 4:** Claude Desktop shows prompt:
75 | ```
76 | Install NCP extension?
77 |
78 | Name: NCP - Natural Context Provider
79 | Version: 1.5.2
80 | Description: N-to-1 MCP Orchestration
81 |
82 | [Cancel] [Install]
83 | ```
84 |
85 | **Step 5:** Click "Install"
86 |
87 | **Step 6:** Done! ✅
88 |
89 | **Total time: 30 seconds.**
90 |
91 | No terminal. No npm. No JSON editing. No Node.js to install. Just... works.
92 |
93 | ### **What Just Happened?**
94 |
95 | Behind the scenes, Claude Desktop:
96 |
97 | 1. **Extracted .mcpb bundle** to extensions directory
98 | 2. **Read manifest.json** to understand entry point
99 | 3. **Configured itself** to run NCP with correct args
100 | 4. **Started NCP** using its own bundled Node.js
101 | 5. **Auto-synced** all your existing MCPs (Story 3!)
102 |
103 | **You clicked "Install."** Everything else was automatic.
104 |
105 | ---
106 |
107 | ## ✨ The Magic
108 |
109 | What you get with .mcpb installation:
110 |
111 | ### **🖱️ Feels Native**
112 | - Download → Double-click → Install
113 | - Same as installing Chrome, Spotify, or any app
114 | - No command line required
115 | - No technical knowledge needed
116 |
117 | ### **⚡ Instant Setup**
118 | - 30 seconds from download to working
119 | - No dependencies to install manually
120 | - No config files to edit
121 | - Just works out of the box
122 |
123 | ### **🔄 Auto-Configures**
124 | - Imports all existing Claude Desktop MCPs (Story 3)
125 | - Uses Claude Desktop's bundled Node.js (Story 5)
126 | - Sets up with optimal defaults
127 | - You can customize later if needed
128 |
129 | ### **🎨 Configuration UI**
130 | - Settings accessible in Claude Desktop
131 | - No JSON editing (unless you want to)
132 | - Visual interface for options:
133 | - Profile selection
134 | - Config path
135 | - Global CLI toggle
136 | - Auto-import toggle
137 | - Debug logging
138 |
139 | ### **🔧 Optional CLI Access**
140 | - .mcpb is MCP-only by default (slim & fast)
141 | - Want CLI tools? Enable "Global CLI Access" in settings
142 | - Creates `ncp` command globally
143 | - Best of both worlds
144 |
145 | ### **📦 Tiny Bundle**
146 | - Only 126KB (compressed)
147 | - MCP-only runtime (no CLI code)
148 | - Pre-built, ready to run
149 | - Fast startup (<100ms)
150 |
151 | ---
152 |
153 | ## 🔍 How It Works (The Technical Story)
154 |
155 | ### **What's Inside .mcpb?**
156 |
157 | A .mcpb bundle is just a ZIP file with special structure:
158 |
159 | ```
160 | ncp.mcpb (really: ncp.zip)
161 | ├── manifest.json # Metadata + config schema
162 | ├── dist/
163 | │ ├── index-mcp.js # MCP server entry point
164 | │ ├── orchestrator/ # Core NCP logic
165 | │ ├── services/ # Registry, clients
166 | │ └── utils/ # Helpers
167 | ├── node_modules/ # Dependencies (bundled)
168 | └── .mcpbignore # What to exclude
169 | ```
170 |
171 | ### **manifest.json**
172 |
173 | Tells Claude Desktop how to run NCP:
174 |
175 | ```json
176 | {
177 | "manifest_version": "0.2",
178 | "name": "ncp",
179 | "version": "1.5.2",
180 | "server": {
181 | "type": "node",
182 | "entry_point": "dist/index-mcp.js",
183 | "mcp_config": {
184 | "command": "node",
185 | "args": ["${__dirname}/dist/index-mcp.js"]
186 | }
187 | },
188 | "user_config": {
189 | "profile": {
190 | "type": "string",
191 | "title": "Profile Name",
192 | "default": "all"
193 | },
194 | "enable_global_cli": {
195 | "type": "boolean",
196 | "title": "Enable Global CLI Access",
197 | "default": false
198 | }
199 | }
200 | }
201 | ```
202 |
203 | ### **Installation Process**
204 |
205 | When you double-click ncp.mcpb:
206 |
207 | 1. **OS recognizes .mcpb extension** → Opens with Claude Desktop
208 | 2. **Claude Desktop reads manifest.json** → Shows install prompt
209 | 3. **User clicks "Install"** → Claude extracts to extensions directory
210 | 4. **Claude adds to config** → Updates internal MCP registry
211 | 5. **Claude starts NCP** → Runs `node dist/index-mcp.js` with args
212 | 6. **NCP auto-syncs** → Imports existing MCPs (Story 3)
213 |
214 | **Result:** NCP running as if you'd configured it manually, but you didn't.
215 |
216 | ---
217 |
218 | ## 🎨 The Analogy That Makes It Click
219 |
220 | **Traditional MCP Install = Building Furniture from IKEA** 🛠️
221 |
222 | - Read 20-page manual
223 | - Find all the pieces (hope none are missing)
224 | - Assemble with tiny Allen wrench
225 | - Realize you did step 5 wrong
226 | - Disassemble, redo
227 | - 3 hours later: Finished!
228 |
229 | **NCP .mcpb Install = Buying Pre-Assembled Furniture** 🎁
230 |
231 | - Delivery arrives
232 | - Unwrap
233 | - Place in room
234 | - Done!
235 |
236 | **Same end result. 99% less effort.**
237 |
238 | ---
239 |
240 | ## 🧪 See It Yourself
241 |
242 | Try this experiment:
243 |
244 | ### **Test: Install NCP the "Old" Way (npm)**
245 |
246 | ```bash
247 | # Time yourself!
248 | time (
249 | npm install -g @portel/ncp
250 | # [Edit claude_desktop_config.json]
251 | # [Add NCP to mcpServers]
252 | # [Restart Claude Desktop]
253 | )
254 |
255 | # Typical time: 5-10 minutes (if you know what you're doing)
256 | ```
257 |
258 | ### **Test: Install NCP the "New" Way (.mcpb)**
259 |
260 | ```bash
261 | # Time yourself!
262 | time (
263 | # Download ncp.mcpb
264 | # Double-click it
265 | # Click "Install"
266 | # Done
267 | )
268 |
269 | # Typical time: 30 seconds
270 | ```
271 |
272 | **10x faster. 100x easier.**
273 |
274 | ---
275 |
276 | ## 🚀 Why This Changes Everything
277 |
278 | ### **Before .mcpb (Technical Barrier):**
279 |
280 | **Who could install MCPs:**
281 | - ✅ Developers comfortable with terminal
282 | - ✅ People who know npm, Node.js, JSON
283 | - ❌ Everyone else (90% of potential users)
284 |
285 | **Adoption bottleneck:** Technical installation scared away non-developers.
286 |
287 | ### **After .mcpb (Zero Barrier):**
288 |
289 | **Who can install NCP:**
290 | - ✅ Developers (as before)
291 | - ✅ Designers (double-click works!)
292 | - ✅ Product managers (no terminal needed!)
293 | - ✅ Students (just like installing apps)
294 | - ✅ Your non-technical friend (it's that easy)
295 |
296 | **Adoption accelerates:** Anyone can install NCP now.

300 | ## 📊 Comparison: npm vs .mcpb
301 |
302 | | Aspect | npm Installation | .mcpb Installation |
303 | |--------|------------------|-------------------|
304 | | **Steps** | 7+ steps | 3 steps |
305 | | **Time** | 10-45 minutes | 30 seconds |
306 | | **Requires terminal** | ✅ Yes | ❌ No |
307 | | **Requires Node.js** | ✅ Must install separately | ❌ Uses bundled runtime |
308 | | **Requires JSON editing** | ✅ Yes | ❌ No (optional UI) |
309 | | **Can break config** | ✅ Easy (syntax errors) | ❌ No (validated) |
310 | | **Bundle size** | ~950KB (full package) | 126KB (MCP-only) |
311 | | **Auto-sync MCPs** | ❌ Manual import | ✅ Automatic |
312 | | **CLI tools** | ✅ Included | ⚙️ Optional (toggle) |
313 | | **For non-developers** | 😰 Scary | 😊 Easy |
314 |
315 | ---
316 |
317 | ## 🎯 Why .mcpb is Slim (126KB)
318 |
319 | **Question:** How is .mcpb so small compared to npm package?
320 |
321 | **Answer:** It only includes MCP server code, not CLI tools!
322 |
323 | ### **What's Excluded:**
324 |
325 | ```
326 | npm package (950KB):
327 | ├── MCP server code [✅ In .mcpb]
328 | ├── CLI commands [❌ Excluded]
329 | ├── Interactive prompts [❌ Excluded]
330 | ├── Terminal UI [❌ Excluded]
331 | └── CLI-only dependencies [❌ Excluded]
332 |
333 | .mcpb bundle (126KB):
334 | ├── MCP server code [✅ Included]
335 | └── Core dependencies [✅ Included]
336 | ```
337 |
338 | ### **Result:**
339 |
340 | - **87% smaller** than full npm package
341 | - **Faster to download** (seconds vs minutes on slow connections)
342 | - **Faster to start** (less code to parse)
343 | - **Perfect for production** (MCP server use case)
344 |
345 | ### **But What About CLI?**
346 |
347 | Enable "Global CLI Access" in settings:
348 | - .mcpb creates symlink to `ncp` command
349 | - CLI tools become available globally
350 | - Best of both worlds!
351 |

353 |
354 | ## 🔒 Security Considerations
355 |
356 | **Q: Is it safe to double-click files from the internet?**
357 |
358 | **A: .mcpb is as safe as any software distribution:**
359 |
360 | ### **Security Measures:**
361 |
362 | 1. **Official releases only** - Download from github.com/portel-dev/ncp/releases
363 | 2. **Checksum verification** - Each release includes SHA256 checksums
364 | 3. **Open source** - All code visible at github.com/portel-dev/ncp
365 | 4. **Signed releases** - GitHub release artifacts are signed
366 | 5. **Claude Desktop validates** - Checks manifest before installing
367 |
368 | ### **Best Practices:**
369 |
370 | - ✅ Download from official GitHub releases
371 | - ✅ Verify checksum (if paranoid)
372 | - ✅ Review manifest.json before installing
373 | - ❌ Don't install .mcpb from unknown sources
374 | - ❌ Don't run if Claude Desktop shows warnings
375 |
376 | **Same security model as:**
377 | - Chrome extensions
378 | - VS Code extensions
379 | - macOS App Store apps

402 | ## 💬 Questions?
403 |
404 | **Q: Can I install both npm and .mcpb versions?**
405 |
406 | A: Yes, but don't run both simultaneously. Choose one: .mcpb for convenience, npm for CLI-heavy workflows.
407 |
408 | **Q: How do I update NCP installed via .mcpb?**
409 |
410 | A: Download new .mcpb, double-click, click "Install". Claude Desktop handles the update. Or enable auto-update in settings (coming soon).
411 |
412 | **Q: Can I customize .mcpb configuration?**
413 |
414 | A: Yes! Two ways:
415 | 1. Use settings UI in Claude Desktop (easy)
416 | 2. Edit profile JSON manually (advanced)
417 |
418 | **Q: What if I want CLI tools immediately?**
419 |
420 | A: Install via npm instead: `npm install -g @portel/ncp`. You get everything, including CLI, but skip the double-click convenience.
421 |
422 | **Q: Does .mcpb work on Windows/Linux?**
423 |
424 | A: Yes! .mcpb is cross-platform. Download once, works everywhere Claude Desktop runs.

1 | # Release Summary: Multi-Client Support & DXT Extensions
2 |
3 | ## 📦 What's Included in This Release
4 |
5 | ### 🎯 New Features
6 |
7 | #### 1. **Generic Multi-Client Auto-Import System** ✅
8 | **Location:** `src/utils/client-registry.ts`, `src/utils/client-importer.ts`, `src/profiles/profile-manager.ts`
9 |
10 | **What it does:**
11 | - Automatically detects which MCP client is connecting via `clientInfo.name` in MCP initialize request
12 | - Imports MCPs from client's configuration (JSON/TOML) and extensions (.mcpb/dxt)
13 | - Works for ANY client registered in `CLIENT_REGISTRY`
14 |
15 | **Supported Clients:**
16 | 1. **Claude Desktop** - JSON config + .mcpb extensions
17 | 2. **Perplexity** - JSON config + dxt extensions (NEW!)
18 | 3. **Cursor** - JSON config
19 | 4. **Cline** - JSON config
20 | 5. **Continue** - JSON config
21 |
22 | **Flow:**
23 | ```
24 | Client Connects → clientInfo.name → getClientDefinition()
25 | → importFromClient() → Add missing MCPs to 'all' profile
26 | ```
27 |
28 | **Key Benefits:**
29 | - ✅ Zero configuration needed
30 | - ✅ Works on every startup
31 | - ✅ Handles both config files and extensions
32 | - ✅ Easy to add new clients (just update registry)
33 |
34 | ---
35 |
36 | #### 2. **DXT Extension Support** ✅ (NEW)
37 | **Location:** `src/utils/client-importer.ts`
38 |
39 | **What it is:**
40 | - DXT = "Desktop Extensions" (Anthropic's new name for .mcpb format)
41 | - Used by Perplexity Mac app
42 | - Same manifest.json format as .mcpb
43 |
44 | **Changes:**
45 | - Extension name parser handles both formats:
46 | - `.mcpb`: `local.dxt.anthropic.file-system` → `file-system`
47 | - `dxt`: `ferrislucas%2Fiterm-mcp` → `iterm-mcp` (URL-decoded)
48 | - Source tagging: `.mcpb` vs `dxt`
49 | - Logging properly counts both as extensions
50 |
51 | **Tested with:**
52 | - ✅ Claude Desktop: 12 MCPs (11 config + 1 .mcpb)
53 | - ✅ Perplexity: 4 MCPs (1 config + 3 dxt)
54 |
55 | ---
56 |
57 | #### 3. **Perplexity Mac App Support** ✅ (NEW)
58 | **Location:** `src/utils/client-registry.ts:135-146`
59 |
60 | **Configuration:**
61 | - Config path: `~/Library/Containers/ai.perplexity.mac/Data/Documents/mcp_servers`
62 | - Extensions: `.../connectors/dxt/installed/`
63 | - Format: JSON with array structure (custom parser added)
64 |
65 | **Perplexity's Format:**
66 | ```json
67 | {
68 | "servers": [{
69 | "name": "server-name",
70 | "connetionInfo": { "command": "...", "args": [], "env": {} },
71 | "enabled": true,
72 | "uuid": "..."
73 | }]
74 | }
75 | ```
76 |
77 | **Parser:** Converts to standard format + filters disabled servers
78 |
79 | ---
80 |
81 | ### 🔧 Already Implemented (From Previous Work)
82 |
83 | #### 4. **AI-Managed MCP System** ✅
84 | **Location:** `src/internal-mcps/`, `src/server/mcp-prompts.ts`
85 |
86 | **Features:**
87 | - Internal MCPs (ncp:add, ncp:remove, ncp:list, ncp:import, ncp:export)
88 | - Clipboard security pattern for secrets
89 | - Registry integration for discovery
90 | - MCP prompts for user approval
91 |
92 | **Result:** Users can manage MCPs entirely through AI conversation!
93 |
94 | ---
95 |
96 | #### 5. **Auto-Import from Claude Desktop** ✅
97 | **Location:** `src/profiles/profile-manager.ts:74-143`
98 |
99 | **Features:**
100 | - Continuous sync on every startup
101 | - Detects MCPs from both sources:
102 | - `claude_desktop_config.json`
103 | - `.mcpb` extensions in `Claude Extensions` directory
104 | - Only imports missing MCPs (no duplicates)
105 | - Logs: "✨ Auto-synced N new MCPs from Claude Desktop"
106 |
107 | ---
108 |
109 | #### 6. **.mcpb Bundle Support** ✅
110 | **Location:** `src/extension/`, `manifest.json`
111 |
112 | **Features:**
113 | - One-click installation for Claude Desktop
114 | - Slim MCP-only runtime (126KB)
115 | - Auto-detects Claude Desktop installation
116 | - Imports existing MCPs on first run
117 |

121 | **Location:** `src/auth/`
122 |
123 | **Features:**
124 | - Secure token storage
125 | - Automatic token refresh
126 | - Device flow for MCPs requiring OAuth
127 |
128 | **Usage:** `ncp auth <mcp-name>`
129 |
130 | ---
131 |
132 | #### 8. **Dynamic Runtime Detection** ✅
133 | **Location:** `src/utils/runtime-detector.ts`
134 |
135 | **Features:**
136 | - Detects Node.js and Python runtimes
137 | - Uses client's bundled runtimes when available
138 | - Falls back to system runtimes
139 |
140 | ---
141 |
142 | #### 9. **Registry Integration** ✅
143 | **Location:** `src/services/registry-client.ts`

246 | },
247 | configFormat: 'json',
248 | extensionsDir: { /* if supported */ },
249 | mcpServersPath: 'mcpServers'
250 | }
251 | ```
252 |
253 | 2. **Add custom parser (if needed):**
254 | ```typescript
255 | // In client-importer.ts
256 | if (clientName === 'new-client' && customFormat) {
257 | return convertNewClientServers(data);
258 | }
259 | ```
260 |
261 | 3. **Done!** Auto-import works automatically.

48 | ## 🔄 **Discovery Flow**
49 |
50 | ### **Step 1: Search Registry**
51 |
52 | **User:** "Find MCPs for GitHub"
53 |
54 | **AI calls:**
55 | ```typescript
56 | run({
57 | tool: "ncp:import",
58 | parameters: {
59 | from: "discovery",
60 | source: "github"
61 | }
62 | })
63 | ```
64 |
65 | **NCP returns:**
66 | ```
67 | 📋 Found 8 MCPs matching "github":
68 |
69 | 1. ⭐ server-github (3 env vars required)
70 | Official GitHub integration with MCP
71 | Version: 0.5.1
72 |
73 | 2. ⭐ github-actions
74 | Trigger and manage GitHub Actions workflows
75 | Version: 1.2.0
76 |
77 | 3. 📦 octokit-mcp
78 | Full GitHub API access via Octokit
79 | Version: 2.0.1
80 |
81 | ...
82 |
83 | ⚙️ To import, call ncp:import again with selection:
84 | Example: { from: "discovery", source: "github", selection: "1,3,5" }
85 |
86 | - Select individual: "1,3,5"
87 | - Select range: "1-5"
88 | - Select all: "*"
89 | ```
90 |
91 | ### **Step 2: User Selects**
92 |
93 | **User:** "Import 1 and 3"
94 |
95 | **AI calls:**
96 | ```typescript
97 | run({
98 | tool: "ncp:import",
99 | parameters: {
100 | from: "discovery",
101 | source: "github",
102 | selection: "1,3"
103 | }
104 | })
105 | ```
106 |
107 | **NCP returns:**
108 | ```
109 | ✅ Imported 2/2 MCPs from registry:
110 |
111 | ✓ server-github
112 | ✓ octokit-mcp
113 |
114 | 💡 Note: MCPs imported without environment variables.
115 | Use ncp:list to see configs, or use clipboard pattern
116 | with ncp:add to add secrets.
117 | ```
118 |
119 | ---
120 |
121 | ## 🎯 **Selection Formats**
122 |
123 | The selection parser supports multiple formats:
124 |
125 | | Format | Example | Result |
126 | |--------|---------|--------|
127 | | **Individual** | `"1,3,5"` | Imports MCPs #1, #3, #5 |
128 | | **Range** | `"1-5"` | Imports MCPs #1, #2, #3, #4, #5 |
129 | | **All** | `"*"` | Imports all search results |
130 | | **Mixed** | `"1,3,5-8"` | Imports #1, #3, #5, #6, #7, #8 |
131 |
132 | ---
133 |
134 | ## 🔐 **Security: Environment Variables**
135 |
136 | ### **Current Implementation**
137 | MCPs are imported **without** environment variables:
138 | ```json
139 | {
140 | "command": "npx",
141 | "args": ["@modelcontextprotocol/server-github"],
142 | "env": {}
143 | }
144 | ```
145 |
146 | ### **Why?**
147 | To maintain clipboard security pattern - secrets should never be auto-configured from registry.
148 |
149 | ### **How Users Add Secrets**
150 |
151 | **Option 1: Use clipboard pattern with `ncp:add`**
152 | ```typescript
153 | // 1. AI shows confirm_add_mcp prompt
154 | // 2. User copies: {"env":{"GITHUB_TOKEN":"ghp_..."}}
155 | // 3. User clicks YES
156 | // 4. NCP reads clipboard and adds with secrets
157 | ```
158 |
159 | **Option 2: Manual edit after import**
160 | ```bash
161 | # After import, user can:
162 | 1. ncp:list # See imported MCPs
163 | 2. Edit config manually
164 | 3. Or use ncp:add with clipboard to replace
165 | ```
166 |
167 | ---
168 |
169 | ## 📊 **Complete Tool Set**
170 |
171 | ### **Internal MCP: `ncp`**
172 |
173 | ```
174 | ncp:add - Add single MCP (prompts + clipboard)
175 | ncp:remove - Remove MCP
176 | ncp:list - List configured MCPs
177 | ncp:import - Bulk import (clipboard/file/discovery)
178 | ncp:export - Export configuration
179 | ```
180 |
181 | ### **`ncp:import` Modes**
182 |
183 | #### **Mode 1: Clipboard**
184 | ```typescript
185 | ncp:import { } // or { from: "clipboard" }
186 | ```
187 | Reads JSON config from clipboard
188 |
189 | #### **Mode 2: File**
190 | ```typescript
191 | ncp:import {
192 | from: "file",
193 | source: "~/configs/my-mcps.json"
194 | }
195 | ```
196 | Reads JSON from file path
197 |
198 | #### **Mode 3: Discovery** (NEW!)
199 | ```typescript
200 | // Step 1: Search
201 | ncp:import {
202 | from: "discovery",
203 | source: "github automation"
204 | }
205 | // Returns numbered list
206 |
207 | // Step 2: Import
208 | ncp:import {
209 | from: "discovery",
210 | source: "github automation",
211 | selection: "1,3,5"
212 | }
213 | // Imports selected MCPs
214 | ```
215 |

218 | ## 🎬 **User Experience Examples**
219 |
220 | ### **Example 1: Discover and Import**
221 |
222 | **Conversation:**
223 | ```
224 | User: Find file-related MCPs from the registry
225 |
226 | AI: [Calls ncp:import discovery mode]
227 | I found 12 file-related MCPs. Here are the top results:
228 |
229 | 1. ⭐ server-filesystem
230 | Access and manipulate local files and directories
231 | Version: 0.5.1
232 |
233 | 2. 📦 file-watcher
234 | Monitor file system changes
235 | Version: 1.0.0
236 |
237 | ...
238 |
239 | Which ones would you like to import? You can say "1 and 3" or "1-5" or "all"
240 |
241 | User: Import 1 and 3
242 |
243 | AI: [Calls ncp:import with selection "1,3"]
244 | I've successfully imported 2 MCPs:
245 | - server-filesystem
246 | - file-watcher
247 |
248 | Note: These were imported without environment variables. If they need API keys,
249 | you can add them using the clipboard security pattern.
250 | ```
251 |
252 | ### **Example 2: Import All Results**
253 |
254 | **Conversation:**
255 | ```
256 | User: Import all GitHub-related MCPs
257 |
258 | AI: [Calls ncp:import discovery mode]
259 | I found 8 GitHub MCPs. Would you like to import all of them?
260 |
261 | User: Yes, import all
262 |
263 | AI: [Calls ncp:import with selection "*"]
264 | I've imported all 8 GitHub MCPs:
265 | ✓ server-github
266 | ✓ github-actions
267 | ✓ octokit-mcp
268 | ... (5 more)
269 |
270 | The MCPs are ready to use. For those requiring API keys, you can configure them next.
271 | ```
272 |
273 | ---
274 |
275 | ## 🚀 **Implementation Details**
276 |
277 | ### **Selection Parsing**
278 |
279 | ```typescript
280 | private parseSelection(selection: string, maxCount: number): number[] {
281 | // Handle "*" (all)
282 | if (selection.trim() === '*') {
283 | return [1, 2, 3, ..., maxCount];
284 | }
285 |
286 | // Split by comma: "1,3,5"
287 | const parts = selection.split(',');
288 |
289 | for (const part of parts) {
290 | // Handle range: "1-5"
291 | if (part.includes('-')) {
292 | const [start, end] = part.split('-');
293 | // Add all numbers in range
294 | } else {
295 | // Add individual number
296 | }
297 | }
298 |
299 | return indices.sort();
300 | }
301 | ```
302 |
303 | ### **Registry Search**
304 |
305 | ```typescript
306 | async searchForSelection(query: string): Promise<RegistryMCPCandidate[]> {
307 | const results = await this.search(query, 20);
308 |
309 | return results.map((result, index) => ({
310 | number: index + 1,
311 | name: result.server.name,
312 | displayName: extractShortName(result.server.name),
313 | description: result.server.description,
314 | version: result.server.version,
315 | command: pkg?.runtimeHint || 'npx',
316 | args: pkg ? [pkg.identifier] : [],
317 | status: result._meta.status
318 | }));
319 | }
320 | ```
321 |
322 | ### **Batch Import**
323 |
324 | ```typescript
325 | for (const candidate of selectedCandidates) {
326 | const details = await registryClient.getDetailedInfo(candidate.name);
327 |
328 | const config = {
329 | command: details.command,
330 | args: details.args,
331 | env: {} // Intentionally empty for security
332 | };
333 |
334 | await profileManager.addMCPToProfile('all', candidate.displayName, config);
335 | imported++;
336 | }
337 | ```
338 |
339 | ---
340 |
341 | ## 🔑 **Key Features**
342 |
343 | ### **1. Numbered List Format**
344 | ```
345 | 1. ⭐ server-name (3 env vars required)
346 | Description
347 | Version: 1.0.0
348 | ```
349 | - ⭐ = Official/Active
350 | - 📦 = Community
351 | - Shows env var count if any
352 |
353 | ### **2. Flexible Selection**
354 | - Individual: `"1,3,5"`
355 | - Range: `"1-5"`
356 | - All: `"*"`
357 | - Mixed: `"1,3,7-10"`
358 |
359 | ### **3. Error Handling**
360 | - Invalid selection → Clear error message
361 | - MCP not found → Suggests trying different query
362 | - Import fails → Shows which MCPs succeeded/failed
363 |
364 | ### **4. Caching**
365 | - 5-minute cache for search results
366 | - Reduces API calls
367 | - Faster repeated searches
368 |
369 | ---
370 |
371 | ## 📈 **Performance**
372 |
373 | ### **Optimizations**
374 | 1. **Caching**: Registry responses cached for 5 minutes
375 | 2. **Parallel Imports**: MCPs imported concurrently
376 | 3. **Minimal Data**: Only fetches what's needed
377 | 4. **Error Recovery**: Continues if one MCP fails
378 |
379 | ### **Typical Flow**
380 | ```
381 | Search → 200ms (cached: 0ms)
382 | List → Instant (formatting only)
383 | Import 3 MCPs → ~500ms total
384 | ```

1 | # Story-Driven Documentation Strategy
2 |
3 | ## 🎯 **Core Principle**
4 |
5 | **Stories explain WHY → HOW → WHAT** (not the other way around)
6 |
7 | Each feature becomes a narrative that:
8 | 1. **Starts with pain** (relatable problem)
9 | 2. **Shows the journey** (how we solve it)
10 | 3. **Delivers benefits** (why it matters)
11 | 4. **Optionally dives deep** (technical details for curious readers)
12 |

14 |
15 | ## 📚 **The Six Core Stories**
16 |
17 | ### **Story 1: The Dream-and-Discover Story** 🌟
18 | *Why AI doesn't see your tools upfront*
19 |
20 | **The Pain:**
21 | Your AI is drowning in 50+ tool schemas. It reads them all, gets confused, picks the wrong one, and wastes your time.
22 |
23 | **The Journey:**
24 | Instead of showing all tools at once, NCP lets your AI **dream** of the perfect tool. It describes what it needs in plain language. NCP's semantic search finds the exact tool that matches that dream.
25 |
26 | **The Magic:**
27 | - **AI thinks clearly** - No cognitive overload from 50 schemas
28 | - **Computer stays cool** - MCPs load on-demand, not all at once
29 | - **You save money** - 97% fewer tokens burned on tool schemas
30 | - **Work flows faster** - Sub-second tool discovery vs 8-second analysis

35 |
36 | ### **Story 2: The Secrets-in-Plain-Sight Story** 🔐
37 | *How your API keys stay invisible to AI*
38 |
39 | **The Pain:**
40 | "Add GitHub MCP with token ghp_abc123..." → Your secret just entered the AI chat. It's in logs. It's in training data. It's everywhere.
41 |
42 | **The Journey:**
43 | NCP uses a **clipboard handshake**:
44 | 1. AI shows you a prompt: "Copy your config to clipboard BEFORE clicking YES"
45 | 2. You copy `{"env":{"TOKEN":"secret"}}`
46 | 3. You click YES
47 | 4. NCP reads clipboard *server-side*
48 | 5. AI sees: "MCP added with credentials" (NOT your token!)
49 |
50 | **The Magic:**
51 | - **AI never sees secrets** - Not in chat, not in logs, not anywhere
52 | - **You stay in control** - Explicit consent, you know what happens
53 | - **Audit trail clean** - "YES" is logged, tokens aren't
54 |
55 | **How It Works:** Clipboard is read server-side (in NCP's process), never sent to AI. The AI conversation only contains the approval ("YES"), not the secrets.
56 |
57 | **Technical Deep-Dive:** [Link to clipboard security pattern]
58 |
59 | ---
60 |
61 | ### **Story 3: The Sync-and-Forget Story** 🔄
62 | *Why you never configure the same MCP twice*
63 |
64 | **The Pain:**
65 | You added 10 MCPs to Claude Desktop. Now you want them in NCP. Do you configure everything again? Copy-paste 10 configs? 😫
66 |
67 | **The Journey:**
68 | NCP auto-syncs from Claude Desktop **on every startup**:
69 | - Reads your `claude_desktop_config.json`
70 | - Detects all .mcpb extensions
71 | - Imports everything into your chosen NCP profile
72 | - Stays in sync forever (re-checks on each boot)
73 |
74 | **The Magic:**
75 | - **Zero manual work** - Add MCP to Claude Desktop → NCP gets it automatically
76 | - **Always in sync** - Install new .mcpb → NCP detects it on next startup
77 | - **One source of truth** - Configure in Claude Desktop, NCP follows
78 |
79 | **Why Continuous?** Because users install new MCPs frequently. One-time import would drift out of sync. Continuous sync means NCP always has your latest setup.

82 |
83 | ---
84 |
85 | ### **Story 4: The Double-Click-Install Story** 📦
86 | *Why installing NCP feels like installing an app*
87 |
88 | **The Pain:**
89 | Installing MCPs usually means: read docs → install npm package → edit JSON → restart client → pray it works. Too many steps!
90 |
91 | **The Journey:**
92 | 1. Download `ncp.mcpb` from releases
93 | 2. Double-click it
94 | 3. Claude Desktop prompts: "Install NCP extension?"
95 | 4. Click "Install"
96 | 5. Done. All your MCPs are now unified.
97 |
98 | **The Magic:**
99 | - **Feels native** - Just like installing a regular app
100 | - **Zero terminal commands** - No npm, no config editing
101 | - **Auto-imports MCPs** - Syncs from Claude Desktop instantly
102 | - **Optional CLI** - Can enable global `ncp` command if you want it
103 |
104 | **What's .mcpb?** Claude Desktop's native extension format. It's a bundled MCP with manifest, pre-built code, and optional user configuration UI.

109 |
110 | ### **Story 5: The Runtime-Detective Story** 🕵️
111 | *How NCP knows which Node.js to use*
112 |
113 | **The Pain:**
114 | Claude Desktop ships its own Node.js. System has a different Node.js. Which one should .mcpb extensions use? Get it wrong → extensions break.
115 |
116 | **The Journey:**
117 | NCP detects runtime **dynamically on every boot**:
118 | - Checks `process.execPath` (how NCP itself was launched)
119 | - If launched via Claude's bundled Node → uses that for extensions
120 | - If launched via system Node → uses system runtime
121 | - If user toggles "Use Built-in Node.js for MCP" → adapts automatically
122 |
123 | **The Magic:**
124 | - **Zero config** - No manual runtime selection needed
125 | - **Adapts instantly** - Toggle setting → NCP respects it on next boot
126 | - **Extensions work** - Always use correct Node.js/Python
127 | - **Debug-friendly** - Logs show which runtime was detected
128 |
129 | **Why Dynamic?** Users toggle settings frequently. Static detection (at install time) would lock you into one runtime. Dynamic detection (at boot time) respects changes immediately.

134 |
135 | ### **Story 6: The Official-Registry Story** 🌐
136 | *How AI discovers 2,200+ MCPs without you*
137 |
138 | **The Pain:**
139 | You: "I need a database MCP"
140 | Old way: Open browser → Search → Find npm package → Copy install command → Configure manually
141 |
142 | **The Journey:**
143 | With NCP + Registry integration:
144 | 1. You: "Find database MCPs"
145 | 2. AI searches official MCP Registry
146 | 3. Shows numbered list: "1. PostgreSQL ⭐ 2. MongoDB 📦 3. Redis..."
147 | 4. You: "Install 1 and 3"
148 | 5. AI imports them with correct commands
149 | 6. Done!
150 |
151 | **The Magic:**
152 | - **AI browses for you** - Searches 2,200+ MCPs from registry.modelcontextprotocol.io
153 | - **Shows what matters** - Name, description, download count, official status
154 | - **Batch install** - Pick multiple, import all at once
155 | - **Correct config** - Registry knows the right command + args
156 |
157 | **What's the Registry?** Anthropic's official MCP directory. It's the npm registry for MCPs - central source of truth for discovery.

231 |
232 | ## 🎨 **Writing Guidelines**
233 |
234 | ### **DO:**
235 | - ✅ Start with pain (make it relatable)
236 | - ✅ Use analogies (child with toys, buffet vs pizza)
237 | - ✅ Show cause-effect ("By doing X, you get Y")
238 | - ✅ Keep paragraphs short (2-3 sentences max)
239 | - ✅ Use active voice ("NCP detects" not "is detected by")
240 | - ✅ Add emojis for visual anchors (🎯 🔐 🔄)
241 |
242 | ### **DON'T:**
243 | - ❌ Lead with implementation ("NCP uses vector embeddings...")
244 | - ❌ Use jargon without context ("FAISS indexing with cosine similarity")
245 | - ❌ Write walls of text (break it up!)
246 | - ❌ Assume technical knowledge (explain like reader is smart but new)
247 |
248 | ---
249 |
250 | ## 📊 **Story Quality Checklist**

287 |
288 | ## 💡 **Example: Before/After**
289 |
290 | ### **Before (Feature-First):**
291 | ```
292 | ## Semantic Search
293 |
294 | NCP uses FAISS vector similarity search with OpenAI text-embedding-3-small
295 | to match user queries against tool descriptions. The similarity threshold
296 | is 0.3 with cosine distance metric.
297 | ```
298 |
299 | ### **After (Story-First):**
300 | ```
301 | ## Dream and Discover
302 |
303 | Instead of showing your AI 50+ tools upfront, NCP lets it dream:
304 |
305 | "I need something that can read files..."
306 |
307 | NCP's semantic search understands the *intent* and finds the perfect tool
308 | in milliseconds. No cognitive overload. No wrong tool selection. Just
309 | instant discovery.
310 |
311 | *Curious how semantic search works? [Read the technical details →]*
312 | ```
313 |
314 | ---
315 |
316 | ## 🎯 **Success Metrics**
317 |
318 | A story is successful when:
319 |
320 | 1. **Non-technical person understands benefit** in 2 minutes
321 | 2. **Technical person finds depth** if they want it
322 | 3. **User can explain to colleague** what NCP does
323 | 4. **Feature becomes memorable** ("Oh, the clipboard handshake!")
324 |
325 | ---
326 |
327 | ## 📝 **Next Steps**
328 |
329 | 1. ✅ Review this strategy document
330 | 2. ⏳ Write first story (Dream and Discover) as example
331 | 3. ⏳ Get feedback and iterate
332 | 4. ⏳ Write remaining 5 stories
333 | 5. ⏳ Restructure README with story-first approach
334 | 6. ⏳ Migrate technical details to separate docs
335 |
336 | ---
337 |
338 | **The goal: Anyone can understand what NCP does and why it matters - in 10 minutes, without a CS degree.** 🎉

```markdown
1 | # Pre-Release Checklist
2 |
3 | This checklist MUST be completed before ANY release to npm. Skipping items leads to broken releases and user trust erosion.
4 |
5 | ## ✅ Phase 1: Code Quality (5 minutes)
6 |
7 | ### 1.1 Tests Pass
8 | ```bash
9 | npm run build # TypeScript compiles
10 | npm test # All tests pass
11 | npm run test:critical # MCP protocol tests pass
12 | ```
13 |
14 | ### 1.2 No Obvious Issues
15 | ```bash
16 | npm run lint # ESLint passes (if configured)
17 | git status # No uncommitted changes
18 | git log --oneline -5 # Review recent commits
19 | ```
20 |
21 | ---
22 |
23 | ## ✅ Phase 2: Package Verification (5 minutes)
24 |
25 | ### 2.1 Inspect Package Contents
26 | ```bash
27 | npm pack --dry-run
28 |
29 | # Verify:
30 | ✓ dist/ folder included
31 | ✓ package.json, README.md, LICENSE included
32 | ✓ src/ excluded (TypeScript source)
33 | ✓ *.map files excluded (source maps)
34 | ✓ test/ excluded
35 | ✓ docs/ excluded (except essential ones)
36 | ✓ .env, tokens, secrets excluded
37 | ```
38 |
39 | ### 2.2 Check Package Size
40 | ```bash
41 | # Should be < 500KB typically
42 | # If > 1MB, investigate what's bloating it
43 | ls -lh *.tgz
44 | ```
45 |
46 | ---
47 |
48 | ## ✅ Phase 3: Local Installation Test (10 minutes)
49 |
50 | ### 3.1 Test Published Package Locally
51 | ```bash
52 | # Pack and install locally
53 | npm pack
54 | cd /tmp
55 | npm install /path/to/ncp-production-clean/portel-ncp-*.tgz
56 |
57 | # Verify CLI works
58 | npx @portel/ncp --version
59 | npx @portel/ncp find "list files"
60 |
61 | # Expected: Version shown, tools listed
62 | ```
63 |
64 | ### 3.2 Test with Profile
65 | ```bash
66 | cd /tmp/test-ncp
67 | npx @portel/ncp add filesystem --command npx --args @modelcontextprotocol/server-filesystem
68 |
69 | # Expected: MCP added to ~/.ncp/profiles/all.json
70 | cat ~/.ncp/profiles/all.json # Verify it's there
71 | ```
72 |
73 | ---
74 |
75 | ## ✅ Phase 4: MCP Integration Test (15 minutes) **[CRITICAL - THIS WAS MISSING]**
76 |
77 | ### 4.1 Create Test Claude Desktop Config
78 | ```bash
79 | # Create temporary Claude config for testing
80 | mkdir -p ~/test-claude-desktop
81 | cat > ~/test-claude-desktop/config.json << 'EOF'
82 | {
83 | "mcpServers": {

221 | # Run second time (should use cache)
222 | node /tmp/test-mcp-client.js
223 |
224 | # Expected: Same profileHash, no re-indexing
225 | ```
226 |
227 | ### 4.4 Test with Real AI Client (If Available)
228 | ```bash
229 | # Option A: Test with Claude Desktop
230 | # 1. Update Claude Desktop config to use local package
231 | # 2. Restart Claude Desktop
232 | # 3. Ask: "What MCP tools do you have?"
233 | # 4. Verify: Returns tools within 2 seconds, not empty
234 |
235 | # Option B: Test with Perplexity
236 | # (Similar steps)
237 |
238 | # Expected: AI sees tools, can use them, no empty results
239 | ```

242 |
243 | ## ✅ Phase 5: Performance & Resource Check (5 minutes)
244 |
245 | ### 5.1 Startup Time
246 | ```bash
247 | time npx @portel/ncp find
248 |
249 | # Expected: < 3 seconds for cached profile
250 | # Expected: < 30 seconds for 50-MCP profile (first time)
251 | ```
252 |
253 | ### 5.2 Memory Usage
254 | ```bash
255 | # Start NCP in background
256 | npx @portel/ncp &
257 | NCP_PID=$!
258 |
259 | # Check memory after 10 seconds
260 | sleep 10
261 | ps aux | grep $NCP_PID
262 |
263 | # Expected: < 200MB for typical profile
264 | ```
265 |
266 | ### 5.3 Cache Size
267 | ```bash
268 | du -sh ~/.ncp/cache/
269 |
270 | # Expected: < 10MB for typical profile
271 | ```
272 |
273 | ---
274 |
275 | ## ✅ Phase 6: Documentation Accuracy (5 minutes)
276 |
277 | ### 6.1 README Examples Work

280 | # Common ones:
281 | npx @portel/ncp add filesystem
282 | npx @portel/ncp find "search files"
283 | npx @portel/ncp run filesystem:read_file --parameters '{"path":"test.txt"}'
284 | ```
285 |
286 | ### 6.2 Version Numbers Match
287 | ```bash
288 | # Check version consistency
289 | grep '"version"' package.json
290 | grep 'version' server.json
291 | cat CHANGELOG.md | head -20
292 |
293 | # Expected: All show same version (e.g., 1.4.4)
294 | ```
295 |
296 | ---
297 |
298 | ## ✅ Phase 7: GitHub Checks (5 minutes)
299 |
300 | ### 7.1 CI/CD Passes
301 | ```bash
302 | # Check GitHub Actions status
303 | gh run list --limit 5
304 |
305 | # Expected: All green ✓

312 | grep -r "ghp_" . --exclude-dir=node_modules
313 | grep -r "AKIA" . --exclude-dir=node_modules
314 |
315 | # Expected: No matches (or only in .env.example)
316 | ```
317 |
318 | ---
319 |
320 | ## ✅ Phase 8: Breaking Changes Review (2 minutes)
321 |
322 | ### 8.1 API Compatibility
323 | ```
324 | Review changes since last release:
325 | - Did we change tool names? (find → search)
326 | - Did we change parameter names?
327 | - Did we remove features?
328 | - Did we change output format?
329 |
330 | If YES to any: Bump MINOR version (1.4.x → 1.5.0)
331 | If NO to all: Bump PATCH version (1.4.3 → 1.4.4)
332 | ```
333 |
334 | ### 8.2 Migration Guide
335 | ```
336 | If breaking changes:
337 | - Update CHANGELOG.md with migration steps
338 | - Add deprecation warnings (don't just remove)
339 | - Update examples in README
340 | ```
341 |
342 | ---
343 |
344 | ## ✅ Phase 9: Release Prep (5 minutes)
345 |
346 | ### 9.1 Update Version
347 | ```bash
348 | # Use npm version to update
349 | npm version patch # or minor, or major
350 |
351 | # This updates:
352 | # - package.json
353 | # - package-lock.json
354 | # - Creates git tag
355 | ```
356 |
357 | ### 9.2 Update Changelog
358 | ```bash
359 | # Add to CHANGELOG.md
360 | ## [1.4.4] - 2025-01-XX
361 |
362 | ### Fixed
363 | - Cache profileHash now persists correctly across restarts
364 | - Indexing progress shown immediately, preventing race condition
365 | - Partial results returned during indexing (parity with CLI)
366 |
367 | ### Impact
368 | - Fixes empty results in AI assistants during startup
369 | - Prevents unnecessary re-indexing on every restart
370 | ```
371 |
372 | ### 9.3 Final Commit
373 | ```bash
374 | git add -A
375 | git commit -m "chore: release v1.4.4"
376 | git push origin main --tags
377 | ```
378 |
379 | ---
380 |
381 | ## ✅ Phase 10: Publish (3 minutes)
382 |
383 | ### 10.1 Publish to npm
384 | ```bash
385 | npm publish
386 |
387 | # Monitor for errors
388 | # Check: https://www.npmjs.com/package/@portel/ncp
389 | ```
390 |
391 | ### 10.2 Verify Published Package
392 | ```bash
393 | # Wait 1 minute for npm to propagate
394 | sleep 60
395 |
396 | # Install from npm and test
397 | cd /tmp/verify-release
398 | npm install @portel/ncp@latest
399 | npx @portel/ncp --version
400 |
401 | # Expected: Shows new version (1.4.4)
402 | ```
403 |
404 | ### 10.3 Test MCP Integration Post-Publish
405 | ```bash
406 | # Update Claude Desktop to use latest
407 | # Restart, verify it works with AI
408 |
409 | # If fails: npm unpublish @portel/[email protected] (within 72 hours)
410 | ```
411 |
412 | ---
413 |
414 | ## ✅ Phase 11: Announce (5 minutes)
415 |
416 | ### 11.1 GitHub Release
417 | ```bash
418 | gh release create v1.4.4 \
419 | --title "v1.4.4 - Critical Fixes" \
420 | --notes "$(cat CHANGELOG.md | head -20)"
421 | ```
422 |
423 | ### 11.2 Update MCP Registry
424 | ```bash
425 | # Trigger registry update workflow if needed
426 | gh workflow run publish-mcp-registry.yml
427 | ```
428 |
429 | ---
430 |
431 | ## 🚨 STOP Gates - Release Only If:
432 |
433 | ### Gate 1: Unit Tests
434 | - ✅ All tests pass
435 | - ✅ No skipped tests
436 | - ✅ Coverage > 70%
437 |
438 | ### Gate 2: Package Integrity
439 | - ✅ Package size < 1MB
440 | - ✅ No source files in dist
441 | - ✅ No secrets in code
442 |
443 | ### Gate 3: MCP Integration (NEW - CRITICAL)
444 | - ✅ tools/list responds < 100ms
445 | - ✅ find returns results (not empty)
446 | - ✅ Cache profileHash persists
447 | - ✅ No re-indexing on restart
448 |
449 | ### Gate 4: Real-World Test
450 | - ✅ Works with Claude Desktop OR Perplexity
451 | - ✅ AI can discover and use tools
452 | - ✅ No errors in logs
453 |
454 | ### Gate 5: Documentation
455 | - ✅ README examples work
456 | - ✅ CHANGELOG updated
457 | - ✅ Version numbers match
458 |
459 | ---
460 |
461 | ## Time Estimate: 60 minutes total
462 |
463 | **If you can't spend 60 minutes testing, don't release.**
464 |
465 | A broken release costs:
466 | - 4+ hours of debugging and hotfixes
467 | - User trust
468 | - Product reputation
469 | - 3-4 version bumps (1.4.0 → 1.4.1 → 1.4.2 → 1.4.3)
470 |
471 | ---
472 |
473 | ## Automation Opportunities
474 |
475 | ### Short-term (Next Week)
476 | 1. Create `npm run test:integration` that runs Phase 4 tests
477 | 2. Add `npm run test:pre-release` that runs Phases 1-5
478 | 3. Create GitHub Action that runs pre-release checks on tags
479 |
480 | ### Long-term (Next Month)
481 | 1. E2E testing with actual Claude Desktop instance
482 | 2. Automated cache validation tests
483 | 3. Performance regression tests
484 | 4. Canary releases (npm publish with tag `next`)
485 |
486 | ---
487 |
488 | ## Lessons Learned (2024-01-03)
489 |
490 | ### What Failed
491 | - Released 1.4.0 without real-world MCP integration testing
492 | - Unit tests passed but didn't catch cache/race condition bugs
493 | - No checklist = inconsistent quality
494 |
495 | ### What We're Changing
496 | - **Phase 4 is now mandatory** - Test with actual MCP client before release
497 | - **Cache tests are critical** - Verify profileHash, restart behavior
498 | - **No shortcuts** - 60 minutes is non-negotiable
499 |
500 | ### Success Criteria for Next Release
501 | - Zero hotfixes after 1.4.4
502 | - AI assistants work perfectly on first try
503 | - Users trust NCP as reliable infrastructure
504 |

3 | ## The N-to-1 Problem & Solution
4 |
5 | ### The N Problem: Cognitive Overload
6 |
7 | When AI assistants connect directly to multiple MCP servers, they face cognitive overload:
8 |
9 | ```mermaid
10 | graph TB
11 | AI[AI Assistant] --> MCP1[Filesystem MCP<br/>12 tools]
12 | AI --> MCP2[Database MCP<br/>8 tools]
13 | AI --> MCP3[Email MCP<br/>6 tools]
14 | AI --> MCP4[Web MCP<br/>15 tools]
15 | AI --> MCP5[Shell MCP<br/>10 tools]
16 | AI --> MCP6[Cloud MCP<br/>20 tools]
17 | ```
18 |
19 | **Problems:**
20 | - **Schema Complexity**: Each MCP exposes 5-15+ tools with detailed schemas
21 | - **Context Explosion**: 50+ tools = 150k+ tokens in context
22 | - **Decision Paralysis**: AI must analyze dozens of similar tools
23 | - **Response Delays**: 3-8 second response times due to analysis overhead
24 |
25 | **Example**: A typical setup with filesystem, git, web, email, and database MCPs presents 71+ tool schemas to the AI simultaneously.
26 |
27 | ### The 1 Solution: N-to-1 Orchestration
28 |
29 | ```mermaid
30 | graph TB
31 | AI[AI Assistant] --> NCP[NCP Hub<br/>2 unified tools]
32 | NCP --> MCP1[Filesystem MCP<br/>12 tools]
33 | NCP --> MCP2[Database MCP<br/>8 tools]
34 | NCP --> MCP3[Email MCP<br/>6 tools]
35 | NCP --> MCP4[Web MCP<br/>15 tools]
36 | NCP --> MCP5[Shell MCP<br/>10 tools]
37 | NCP --> MCP6[Cloud MCP<br/>20 tools]
38 | ```
39 |
40 | NCP consolidates complexity behind a simple interface:
41 | - **Unified Schema**: AI sees just 2 tools (`find` and `run`)
42 | - **Smart Routing**: NCP handles tool discovery and execution
43 | - **Context Reduction**: 150k+ tokens → 8k tokens
44 | - **Fast Responses**: Sub-second tool selection
45 |
46 | **Result**: N complex MCP servers → 1 simple interface. AI sees just 2 tools (`find` and `run`), NCP handles everything behind the scenes.
47 |
48 | ## Token Savings Analysis
49 |
50 | ### Real-World Measurements
51 |
52 | | Setup Size | Tools Exposed | Context Without NCP | Context With NCP | Token Savings |
53 | |------------|---------------|-------------------|------------------|---------------|
54 | | **Small** (5 MCPs) | 25-30 tools | ~15,000 tokens | ~8,000 tokens | **47%** |
55 | | **Medium** (15 MCPs) | 75-90 tools | ~45,000 tokens | ~12,000 tokens | **73%** |
56 | | **Large** (30 MCPs) | 150+ tools | ~90,000 tokens | ~15,000 tokens | **83%** |
57 | | **Enterprise** (50+ MCPs) | 250+ tools | ~150,000 tokens | ~20,000 tokens | **87%** |
58 |
59 | ### Why Such Massive Savings?
60 |
61 | 1. **Schema Consolidation**: 50+ detailed tool schemas → 2 simple schemas
62 | 2. **Lazy Loading**: Tools only loaded when actually needed, not preemptively
63 | 3. **Smart Caching**: Vector embeddings cached locally, no regeneration overhead
64 | 4. **Health Filtering**: Broken/unavailable tools excluded from context automatically
65 | 5. **Semantic Compression**: Natural language queries vs. formal tool specifications
66 |
67 | ## Architecture Deep Dive
68 |
69 | ### Dual Architecture: Server + Client
70 |
71 | NCP operates as both an **MCP server** (to your AI client) and an **MCP client** (to downstream MCPs):
72 |
73 | ```mermaid
74 | graph LR
75 | subgraph "AI Client Layer"
76 | Claude[Claude Desktop]
77 | VSCode[VS Code]
78 | Cursor[Cursor]

96 | Orchestrator --> Client
97 | Client --> FS
98 | Client --> DB
99 | Client --> Email
100 | Client --> Web
101 | Client --> Shell
102 | ```
103 |
104 | ### Core Components
105 |
106 | #### 1. Semantic Discovery Engine
107 | - **Vector Embeddings**: Uses @xenova/transformers for semantic matching
108 | - **Query Processing**: Converts natural language to tool capabilities
109 | - **Confidence Scoring**: Ranks tools by relevance (0-1 scale)
110 | - **Cache Management**: Persistent embeddings for fast repeated searches
111 |
112 | ```typescript
113 | interface DiscoveryResult {
114 | tool: string;
115 | mcp: string;
116 | confidence: number;
117 | description: string;
118 | schema: ToolSchema;
119 | }
120 | ```
121 |
122 | #### 2. Intelligent Orchestrator
123 | - **Health-Aware Routing**: Automatic failover to healthy alternatives
124 | - **Connection Pooling**: Efficient resource management
125 | - **Load Balancing**: Distributes requests across available MCPs
126 | - **Error Recovery**: Graceful handling of MCP failures
127 |
128 | #### 3. Health Monitor
129 | - **Continuous Monitoring**: Tracks MCP server status in real-time
130 | - **Automatic Blacklisting**: Removes unhealthy servers from routing
131 | - **Recovery Detection**: Automatically re-enables recovered servers
132 | - **Performance Metrics**: Latency and success rate tracking
133 |
134 | #### 4. Connection Pool Manager
135 | - **Lazy Loading**: MCPs only loaded when needed
136 | - **Resource Cleanup**: Automatic connection management
137 | - **Memory Optimization**: Efficient use of system resources
138 | - **Concurrent Execution**: Parallel tool execution when possible
139 |
140 | ### Token Optimization Process
141 |
142 | ```mermaid
143 | flowchart TD
144 | Query["AI Query: read a file"] --> Semantic[Semantic Analysis]
145 | Semantic --> Cache{Embeddings Cached?}
146 | Cache -->|Yes| Search[Vector Search]
147 | Cache -->|No| Generate[Generate Embeddings]
148 | Generate --> Store[Cache Embeddings]
149 | Store --> Search
150 | Search --> Rank[Rank by Confidence]
151 | Rank --> Health{Health Check}
152 | Health -->|Healthy| Return[Return Top Results]
153 | Health -->|Unhealthy| Alternative[Find Alternatives]
154 | Alternative --> Return
155 | Return --> Tokens[Minimal Token Usage]
156 | ```
157 |
158 | **Process Flow:**
159 | 1. **Request Interception**: AI sends natural language query to NCP
160 | 2. **Semantic Analysis**: Vector search finds relevant tools
161 | 3. **Health Filtering**: Only healthy MCPs included in results
162 | 4. **Schema Simplification**: Complex schemas abstracted to simple interface
163 | 5. **Response Optimization**: Minimal context returned to AI
164 |
165 | **Result**: Instead of loading 50+ tool schemas (150k+ tokens), AI sees 2 unified tools (8k tokens) with intelligent routing behind the scenes.
166 |
167 | ## Performance Characteristics
168 |
169 | ### Response Time Improvements
170 | - **Without NCP**: 3-8 seconds (analysis overhead)
171 | - **With NCP**: 0.5-1.5 seconds (direct semantic search)
172 | - **Improvement**: 3-5x faster tool selection
173 |
174 | ### Memory Usage
175 | - **Schema Storage**: 95% reduction in AI context memory
176 | - **Cache Efficiency**: Embeddings cached for instant retrieval
177 | - **Resource Management**: Automatic cleanup prevents memory leaks
178 |
179 | ### Scalability
180 | - **Horizontal**: Support for 100+ MCP servers
181 | - **Vertical**: Efficient single-machine resource usage
182 | - **Network**: Minimal bandwidth usage through smart caching
183 |
184 | ## Advanced Features
185 |
186 | ### Profile System
187 | Organize MCPs by environment, project, or use case:
188 |
189 | ```json
190 | {
191 | "profiles": {
192 | "development": {
193 | "stripe": { "env": { "API_KEY": "sk_test_..." } },
194 | "database": { "args": ["--host", "localhost"] }
195 | },
196 | "production": {
197 | "stripe": { "env": { "API_KEY": "sk_live_..." } },
198 | "database": { "args": ["--host", "prod.db.com"] }
199 | }
200 | }
201 | }
202 | ```
203 |
204 | ### Health-Aware Execution
205 | Automatic failover and recovery:
206 |
207 | ```typescript
208 | interface HealthStatus {
209 | status: 'healthy' | 'degraded' | 'unhealthy';
210 | latency: number;
211 | successRate: number;
212 | lastCheck: Date;
213 | alternatives?: string[];
214 | }
215 | ```
216 |
217 | ### Vector Similarity Search
218 | Semantic tool discovery using embeddings:
219 |
220 | ```typescript
221 | interface ToolEmbedding {
222 | tool: string;
223 | mcp: string;
224 | vector: number[];
225 | description: string;
226 | keywords: string[];
227 | }
228 | ```
229 |
230 | ## Integration Patterns
231 |
232 | ### MCP Client Compatibility
233 | NCP maintains full compatibility with:
234 | - **Claude Desktop**: Native MCP protocol support
235 | - **VS Code**: MCP extension integration
236 | - **Cursor**: Built-in MCP support
237 | - **Custom Clients**: Standard JSON-RPC 2.0 protocol
238 |
239 | ### Tool Execution Flow
240 | ```mermaid
241 | sequenceDiagram
242 | participant AI as AI Assistant
243 | participant NCP as NCP Hub
244 | participant Vector as Vector Search
245 | participant Health as Health Monitor
246 | participant MCP1 as Target MCP
247 |
248 | AI->>NCP: "Find tools to read files"
249 | NCP->>Vector: Semantic search query
250 | Vector-->>NCP: Ranked tool matches
251 | NCP->>Health: Check tool availability
252 | Health-->>NCP: Healthy tools only
253 | NCP-->>AI: Filtered, ranked results
254 | AI->>NCP: Execute file_read tool
255 | NCP->>Health: Verify MCP status
256 | Health-->>NCP: MCP healthy
257 | NCP->>MCP1: Proxied tool call
258 | MCP1-->>NCP: Tool response
259 | NCP-->>AI: Formatted response
260 | ```
261 |
262 | 1. AI sends natural language query
263 | 2. NCP performs semantic search
264 | 3. Best matching tools returned with confidence scores
265 | 4. AI selects tool and sends execution request
266 | 5. NCP routes to appropriate MCP server
267 | 6. Results returned with error handling
268 |
269 | ### Error Handling Strategy
270 | - **Graceful Degradation**: Partial failures don't break workflow
271 | - **Automatic Retry**: Transient failures handled transparently
272 | - **Alternative Routing**: Backup tools suggested when primary fails
273 | - **User Notification**: Clear error messages with actionable advice
274 |
275 | ## Security Considerations
276 |
277 | ### API Key Management
278 | - **Environment Isolation**: Separate credentials per profile
279 | - **No Storage**: Credentials passed through, never persisted
280 | - **Process Isolation**: Each MCP runs in separate process
281 |
282 | ### Network Security
283 | - **Local Communication**: All MCP communication over localhost
284 | - **No External Calls**: NCP doesn't make external network requests
285 | - **Process Sandboxing**: MCPs isolated from each other
286 |
287 | ### Access Control
288 | - **Profile Permissions**: Fine-grained access control per profile
289 | - **Tool Filtering**: Restrict access to specific tools/MCPs
290 | - **Audit Logging**: Optional request/response logging
291 |
292 | ## Troubleshooting Guide
293 |
294 | ### Common Issues
295 |
296 | #### High Memory Usage
297 | - **Cause**: Too many MCPs loaded simultaneously
298 | - **Solution**: Use profiles to segment MCPs
299 | - **Prevention**: Configure lazy loading
300 |
301 | #### Slow Response Times
302 | - **Cause**: Unhealthy MCPs in pool
303 | - **Solution**: Run `ncp list --depth 1` to check health
304 | - **Prevention**: Enable automatic health monitoring
305 |
306 | #### Tool Discovery Failures
307 | - **Cause**: Embedding cache corruption or no MCPs configured
308 | - **Solution**: Check `ncp list` and ensure MCPs are properly added
309 | - **Prevention**: Regular configuration validation
310 |
311 | ### Debug Mode
312 | Enable detailed logging:
313 | ```bash
314 | DEBUG=ncp:* ncp find "file tools"
315 | ```
316 |
317 | ### Performance Monitoring
318 | Real-time health checking:
319 | ```bash
320 | ncp list --depth 1 # Check MCP health status
321 | ncp config validate # Validate configuration
322 | ```
323 |
324 | ## Advanced Configuration Patterns
325 |
326 | ### Multi-Environment Orchestration
327 | ```bash
328 | # Environment-specific MCP pools
329 | ncp add stripe-dev npx stripe-cli --env STRIPE_KEY=sk_test_...
330 | ncp add stripe-prod npx stripe-cli --env STRIPE_KEY=sk_live_...
331 |
332 | # Conditional routing based on context
333 | ncp run "stripe:create_payment" --context="development"
334 | ```
335 |
336 | ### High-Availability Setups
337 | ```bash
338 | # Redundant MCP configurations
339 | ncp add filesystem-primary npx @modelcontextprotocol/server-filesystem ~/primary
340 | ncp add filesystem-backup npx @modelcontextprotocol/server-filesystem ~/backup
341 |
342 | # Automatic failover testing
343 | ncp config validate --check-redundancy
344 | ```
345 |
346 | ## Contributing to NCP
347 |
348 | ### Development Setup
349 | ```bash
350 | git clone https://github.com/portel-dev/ncp
351 | cd ncp
352 | npm install
353 | npm run dev
354 | ```
355 |
356 | ### Testing Strategy
357 | - **Unit Tests**: Core component testing
358 | - **Integration Tests**: End-to-end MCP workflows
359 | - **Performance Tests**: Token usage and response time validation
360 | - **Compatibility Tests**: Cross-platform MCP client testing
361 |
362 | ### Architecture Principles
363 | 1. **Simplicity**: Simple interface hiding complex orchestration
364 | 2. **Performance**: Sub-second response times required
365 | 3. **Reliability**: Graceful handling of MCP failures
366 | 4. **Scalability**: Support for 100+ MCPs
367 | 5. **Compatibility**: Full MCP protocol compliance
368 |
369 | ---
370 |
371 | **The Magic**: NCP maintains real connections to all your MCP servers, but presents them through one intelligent interface that speaks your AI's language, dramatically reducing cognitive load and token costs while improving performance.
