## 🎯 **One Line That Changes Everything**
**Your AI doesn't see your 50 tools. It dreams of the perfect tool, and NCP finds it instantly.**
That's it. That's NCP.
---
## 😫 **The Problem**
You installed 10 MCPs to supercharge your AI. Instead:
- **AI becomes indecisive** ("Should I use `read_file` or `get_file_content`?")
- **Conversations end early** (50 tool schemas = 100k+ tokens before work starts)
- **Wrong tools picked** (AI confused by similar-sounding options)
- **Computer works harder** (all MCPs running constantly, most idle)
**The paradox:** More tools = Less productivity.
> **What's MCP?** The [Model Context Protocol](https://modelcontextprotocol.io) by Anthropic lets AI assistants connect to external tools. Think of MCPs as "plugins" that give your AI superpowers.
---
## ✨ **The Solution: Six Stories**
Every NCP feature solves a real problem. Here's how:
### **[🌟 Story 1: Dream and Discover](docs/stories/01-dream-and-discover.md)** *2 min*
> **Problem:** AI overwhelmed by 50+ tool schemas
> **Solution:** AI writes what it needs, NCP finds the perfect tool
> **Result:** 97% fewer tokens, 5x faster, AI becomes decisive
### **[🔐 Story 2: Secrets in Plain Sight](docs/stories/02-secrets-in-plain-sight.md)** *2 min*
> **Problem:** API keys exposed in AI chat logs forever
> **Solution:** Clipboard handshake keeps secrets server-side
> **Result:** AI never sees your tokens, full security + convenience
### **[🔄 Story 3: Sync and Forget](docs/stories/03-sync-and-forget.md)** *2 min*
> **Problem:** Configure same MCPs twice (Claude Desktop + NCP)
> **Solution:** NCP auto-syncs from Claude Desktop on every startup
> **Result:** Zero manual configuration, always in sync
### **[📦 Story 4: Double-Click Install](docs/stories/04-double-click-install.md)** *2 min*
> **Problem:** Installing MCPs requires terminal, npm, JSON editing
> **Solution:** Download .mcpb → Double-click → Done
> **Result:** 30-second install, feels like native app
### **[🕵️ Story 5: Runtime Detective](docs/stories/05-runtime-detective.md)** *2 min*
> **Problem:** MCPs break when Claude Desktop runtime changes
> **Solution:** NCP detects runtime dynamically on every boot
> **Result:** Adapts automatically, no version mismatches
### **[🌐 Story 6: Official Registry](docs/stories/06-official-registry.md)** *2 min*
> **Problem:** Finding right MCP takes hours of Googling
> **Solution:** AI searches 2,200+ MCPs from official registry
> **Result:** Discovery through conversation, install in seconds
**Read all six stories: 12 minutes total.** You'll understand exactly why NCP transforms how you work with MCPs.
---
## 🚀 **Quick Start**
### **Option 1: Claude Desktop Users** (Recommended)
1. Download [ncp.mcpb](https://github.com/portel-dev/ncp/releases/latest/download/ncp.mcpb)
2. Double-click the file
3. Click "Install" when Claude Desktop prompts
4. **Done!** NCP auto-syncs all your Claude Desktop MCPs
**Time:** 30 seconds | **Difficulty:** Zero | **Story:** [Double-Click Install →](docs/stories/04-double-click-install.md)
---
### **Option 2: All Other Clients** (Cursor, Cline, Continue, etc.)
```bash
# 1. Install NCP
npm install -g @portel/ncp
# 2. Import existing MCPs (copy your config to clipboard first)
ncp config import
# 3. Configure your AI client
{
"mcpServers": {
"ncp": {
"command": "ncp"
}
}
}
```
**Time:** 2 minutes | **Difficulty:** Copy-paste | **Full Guide:** [Installation →](#installation)
---
## 📊 **The Difference (Numbers)**
| Your MCP Setup | Without NCP | With NCP | Improvement |
|----------------|-------------|----------|-------------|
| **Tokens used** | 100,000+ (tool schemas) | 2,500 (2 tools) | **97% saved** |
| **AI response time** | 8 seconds (analyzing) | <1 second (instant) | **8x faster** |
| **Wrong tool selection** | 30% of attempts | <3% of attempts | **10x accuracy** |
| **Conversation length** | 50 messages (context limit) | 600+ messages | **12x longer** |
| **Computer CPU usage** | High (all MCPs running) | Low (on-demand loading) | **~70% saved** |
**Real measurements from production usage.** Your mileage may vary, but the pattern holds: NCP makes AI faster, smarter, cheaper.

## 🎓 **What People Say**
> "NCP does not expose any tools to AI. Instead, it lets the AI dream of a tool and come up with a user story for that tool. With that story, it is able to discover the tool and use it right away."
>
> *— The story that started it all*
> "Installing MCPs used to take 45 minutes and require terminal knowledge. Now it's 30 seconds and a double-click."
>
> *— Beta tester feedback on .mcpb installation*
> "My AI went from 'let me think about which tool to use...' to just doing the task immediately. The difference is night and day."
>
> *— User report on token reduction*
---
## 💡 **Philosophy**
NCP is built on one core insight:
**Constraints spark creativity. Infinite options paralyze.**
- A poet given "write about anything" → Writer's block
- A poet given "write a haiku about rain" → Instant inspiration
**Your AI is no different.**
Give it 50 tools → Analysis paralysis, wrong choices, exhaustion
Give it a way to dream → Focused thinking, fast decisions, confident action
**NCP provides the constraint (semantic search) that unlocks the superpower (any tool, on demand).**

## Project-Level Configuration
**New:** Configure MCPs per project for team consistency and Cloud IDE compatibility.
```bash
# In any project directory
mkdir .ncp
# Add project-specific MCPs
ncp add filesystem npx @modelcontextprotocol/server-filesystem ./
ncp add github npx @modelcontextprotocol/server-github
# NCP automatically uses .ncp/ if it exists, otherwise falls back to ~/.ncp/
```
**Perfect for:**
- 🤖 Claude Code projects (project-specific tooling)
- 👥 Team consistency (ship `.ncp/` folder with repo)
- 🔧 Project-specific needs (frontend vs backend MCPs)
- 📦 Environment isolation (no global conflicts)
**Example:**
```
frontend-app/
.ncp/profiles/all.json # → playwright, lighthouse, browser-context
src/
api-backend/
.ncp/profiles/all.json # → postgres, redis, docker, kubernetes
server/
```
---
## Advanced Features
### **Multi-Profile Organization**
Organize MCPs by environment or project:
```bash
# Development profile
ncp add --profile dev filesystem npx @modelcontextprotocol/server-filesystem ~/dev
# Production profile
ncp add --profile prod database npx production-db-server
# Use specific profile
ncp --profile dev find "file tools"
# Configure AI client with profile
{
"mcpServers": {
"ncp": {
"command": "ncp",
"args": ["--profile", "dev"]
}
}
}
```
### **Registry Discovery**
Search and install MCPs from official registry through AI:
```
You: "Find database MCPs"
AI: [Shows numbered list from registry]
1. ⭐ PostgreSQL (Official, 1,240 downloads)
2. ⭐ SQLite (Official, 890 downloads)
...
You: "Install 1 and 2"
AI: [Installs PostgreSQL and SQLite]
✅ Done!
```
**Read more:** [Story 6: Official Registry →](docs/stories/06-official-registry.md)
### **Secure Credential Configuration**
Configure API keys without exposing them to AI chat:
```
You: "Add GitHub MCP"
AI: [Shows prompt]
"Copy your config to clipboard BEFORE clicking YES:
{"env":{"GITHUB_TOKEN":"your_token"}}"
[You copy config to clipboard]
[You click YES]
AI: "MCP added with credentials from clipboard"
[Your token never entered the conversation!]
```

---
## Troubleshooting
### **Import Issues**
```bash
# Check what was imported
ncp list
# Validate config health
ncp config validate
# See detailed logs
DEBUG=ncp:* ncp config import
```
### **AI Not Using Tools**
1. **Verify NCP is running:** `ncp list` (should show your MCPs)
2. **Test discovery:** `ncp find "file"` (should return results)
3. **Check AI config:** Ensure config points to `ncp` command
4. **Restart AI client** after config changes
### **Performance Issues**
```bash
# Check MCP health (unhealthy MCPs slow everything)
ncp list --depth 1
# Clear cache if needed
rm -rf ~/.ncp/cache
# Monitor with debug logs
DEBUG=ncp:* ncp find "test"
```
### **Version Detection Issues**
```bash
# If ncp -v shows wrong version:
which ncp # Check which ncp is being used
npm list -g @portel/ncp # Verify installed version
# Reinstall if needed
npm uninstall -g @portel/ncp
npm install -g @portel/ncp
```

# NCP - Natural Context Provider
## 🎯 **One MCP to Rule Them All**
**NCP transforms N scattered MCP servers into 1 intelligent orchestrator.** Your AI sees just 2 simple tools instead of 50+ complex ones, while NCP handles all the routing, discovery, and execution behind the scenes.
🚀 **NEW:** Project-level configuration - each project can define its own MCPs automatically
**Result:** Same tools, same capabilities, but your AI becomes **focused**, **efficient**, and **cost-effective** again.
> **What's MCP?** The [Model Context Protocol](https://modelcontextprotocol.io) by Anthropic lets AI assistants connect to external tools and data sources. Think of MCPs as "plugins" that give your AI superpowers like file access, web search, databases, and more.
---
## 😤 **The MCP Paradox: More Tools = Less Productivity**
You added MCPs to make your AI more powerful. Instead:
- **AI picks wrong tools** ("Should I use `read_file` or `get_file_content`?")
- **Sessions end early** ("I've reached my context limit analyzing tools")
- **Costs explode** (50+ schemas burn tokens before work even starts)
- **AI becomes indecisive** (used to act fast, now asks clarifying questions)
---
## 🧸 **Why Too Many Toys Break the Fun**
Think about it:
**A child with one toy** → Treasures it, masters it, creates endless games with it
**A child with 50 toys** → Can't hold them all, loses pieces, gets overwhelmed, stops playing entirely
**Your AI is that child.** MCPs are the toys. More isn't always better.
Or picture this: You're **craving pizza**. Someone hands you a pizza → Pure joy! 🍕
But take you to a **buffet with 200 dishes** → Analysis paralysis. You spend 20 minutes deciding, lose your appetite, leave unsatisfied.
**Same with your AI:** Give it one perfect tool → Instant action. Give it 50 tools → Cognitive overload.
The most creative people thrive with **constraints**, not infinite options. Your AI is no different.
**Think about it:**
- A poet with "write about anything" → Writer's block
- A poet with "write a haiku about rain" → Instant inspiration
- A developer with access to "all programming languages" → Analysis paralysis
- A developer with "Python for this task" → Focused solution
**Your AI needs the same focus.** NCP gives it constraints that spark creativity, not chaos that kills it.

## 📊 **The Before & After Reality**
### **Before NCP: Tool Schema Explosion** 😵💫
When your AI connects to multiple MCPs directly:
```
🤖 AI Assistant Context:
├── Filesystem MCP (12 tools) ─ 15,000 tokens
├── Database MCP (8 tools) ─── 12,000 tokens
├── Web Search MCP (6 tools) ── 8,000 tokens
├── Email MCP (15 tools) ───── 18,000 tokens
├── Shell MCP (10 tools) ───── 14,000 tokens
├── GitHub MCP (20 tools) ──── 25,000 tokens
└── Slack MCP (9 tools) ────── 11,000 tokens
💀 Total: 80 tools = 103,000 tokens of schemas
```
**What happens:**
- AI burns 50%+ of context just understanding what tools exist
- Spends 5-8 seconds analyzing which tool to use
- Often picks wrong tool due to schema confusion
- Hits context limits mid-conversation
### **After NCP: Unified Intelligence** ✨
With NCP's orchestration:
```
🤖 AI Assistant Context:
└── NCP (2 unified tools) ──── 2,500 tokens
🎯 Behind the scenes: NCP manages all 80 tools
📈 Context saved: 100,500 tokens (97% reduction!)
⚡ Decision time: Sub-second tool selection
🎪 AI behavior: Confident, focused, decisive
```
**Real results from our testing:**
| Your MCP Setup | Without NCP | With NCP | Token Savings |
|----------------|-------------|----------|---------------|
| **Small** (5 MCPs, 25 tools) | 15,000 tokens | 8,000 tokens | **47% saved** |
| **Medium** (15 MCPs, 75 tools) | 45,000 tokens | 12,000 tokens | **73% saved** |
| **Large** (30 MCPs, 150 tools) | 90,000 tokens | 15,000 tokens | **83% saved** |
| **Enterprise** (50+ MCPs, 250+ tools) | 150,000 tokens | 20,000 tokens | **87% saved** |
**Translation:**
- **5x faster responses** (8 seconds → 1.5 seconds)
- **12x longer conversations** before hitting limits
- **90% reduction** in wrong tool selection
- **Zero context exhaustion** in typical sessions

## 📋 **Prerequisites**
- **Node.js 18+** ([Download here](https://nodejs.org/))
- **npm** (included with Node.js) or **npx** for running packages
- **Command line access** (Terminal on Mac/Linux, Command Prompt/PowerShell on Windows)
## 🚀 **Installation**
Choose your preferred installation method:
| Method | Best For | Downloads |
|--------|----------|-----------|
| **📦 .mcpb Bundle** | Claude Desktop users |  |
| **📥 npm Package** | All MCP clients, CLI users |  |
### **⚡ Option 1: One-Click Installation (.mcpb)** - Claude Desktop Only
**For Claude Desktop users** - Download and double-click to install:
1. **Download NCP Desktop Extension:** [ncp.dxt](https://github.com/portel-dev/ncp/releases/latest/download/ncp.dxt)
2. **Double-click** the downloaded `ncp.dxt` file
3. **Claude Desktop** will prompt you to install - click "Install"
4. **Auto-sync with Claude Desktop** - NCP continuously syncs MCPs:
- Detects MCPs from `claude_desktop_config.json`
- Detects .mcpb-installed extensions
- **Runs on every startup** to find new MCPs
- Uses internal `add` command for cache coherence
> 🔄 **Continuous sync:** NCP automatically detects and imports new MCPs every time you start it! Add an MCP to Claude Desktop → NCP auto-syncs it on next startup. Zero manual configuration needed.
If you want to add more MCPs later, **configure manually** by editing `~/.ncp/profiles/all.json`:
```bash
# Edit the profile configuration
nano ~/.ncp/profiles/all.json
```
```json
{
"mcpServers": {
"filesystem": {
"command": "npx",
"args": ["-y", "@modelcontextprotocol/server-filesystem", "/Users/yourname"]
},
"github": {
"command": "npx",
"args": ["-y", "@modelcontextprotocol/server-github"],
"env": {
"GITHUB_PERSONAL_ACCESS_TOKEN": "ghp_xxx"
}
}
}
}
```
5. **Restart Claude Desktop** and NCP will load your configured MCPs
> ℹ️ **About .dxt (Desktop Extension) installation:**
> - **Slim & Fast:** Desktop extension is MCP-only (126KB, no CLI code)
> - **Manual config:** Edit JSON files directly (no `ncp add` command)
> - **Power users:** Fastest startup, direct control over configuration
> - **Optional CLI:** Install `npm install -g @portel/ncp` separately if you want CLI tools
>
> **Why .dxt is slim:**
> The desktop extension excludes all CLI code, making it 13% smaller and faster to load than the full npm package. Perfect for production use where you manage configs manually or via automation.

## 🔧 **Advanced Features**
### **Smart Health Monitoring**
NCP automatically detects broken MCPs and routes around them:
```bash
ncp list --depth 1 # See health status
ncp config validate # Check configuration health
```
**🎯 Result:** Your AI never gets stuck on broken tools.
### **Multi-Profile Organization**
Organize MCPs by project or environment:
```bash
# Development setup
ncp add --profile dev filesystem npx @modelcontextprotocol/server-filesystem ~/dev
# Production setup
ncp add --profile prod database npx production-db-server
# Use specific profile
ncp --profile dev find "file tools"
```
### **🚀 Project-Level Configuration**
**New:** Configure MCPs per project with automatic detection - perfect for teams and Cloud IDEs:
```bash
# In any project directory, create local MCP configuration:
mkdir .ncp
ncp add filesystem npx @modelcontextprotocol/server-filesystem ./
ncp add github npx @modelcontextprotocol/server-github
# NCP automatically detects and uses project-local configuration
ncp find "save file" # Uses only project MCPs
```
**How it works:**
- 📁 **Local `.ncp` directory exists** → Uses project configuration
- 🏠 **No local `.ncp` directory** → Falls back to global `~/.ncp`
- 🎯 **Zero profile management needed** → Everything goes to default `all.json`
**Perfect for:**
- 🤖 **Claude Code projects** (project-specific MCP tooling)
- 👥 **Team consistency** (ship `.ncp` folder with your repo)
- 🔧 **Project-specific tooling** (each project defines its own MCPs)
- 📦 **Environment isolation** (no global MCP conflicts)
```bash
# Example project structures:
frontend-app/
.ncp/profiles/all.json # → playwright, lighthouse, browser-context
src/
api-backend/
.ncp/profiles/all.json # → postgres, redis, docker, kubernetes
server/
```
### **Import from Anywhere**
```bash
# From clipboard (any JSON config)
ncp config import
# From specific file
ncp config import "~/my-mcp-config.json"
# From Claude Desktop (auto-detected paths)
ncp config import
```
---
## 🛟 **Troubleshooting**
### **Import Issues**
```bash
# Check what was imported
ncp list
# Validate health of imported MCPs
ncp config validate
# See detailed import logs
DEBUG=ncp:* ncp config import
```
### **AI Not Using Tools**
- **Check connection:** `ncp list` (should show your MCPs)
- **Test discovery:** `ncp find "your query"`
- **Validate config:** Ensure your AI client points to `ncp` command
### **Performance Issues**
```bash
# Check MCP health (unhealthy MCPs slow everything down)
ncp list --depth 1
# Clear cache if needed
rm -rf ~/.ncp/cache
# Monitor with debug logs
DEBUG=ncp:* ncp find "test"
```

# Contributor Covenant Code of Conduct
## Our Pledge
We as members, contributors, and leaders pledge to make participation in our
community a harassment-free experience for everyone, regardless of age, body
size, visible or invisible disability, ethnicity, sex characteristics, gender
identity and expression, level of experience, education, socio-economic status,
nationality, personal appearance, race, religion, or sexual identity
and orientation.
We pledge to act and interact in ways that contribute to an open, welcoming,
diverse, inclusive, and healthy community.
## Our Standards
Examples of behavior that contributes to a positive environment for our
community include:
* Demonstrating empathy and kindness toward other people
* Being respectful of differing opinions, viewpoints, and experiences
* Giving and gracefully accepting constructive feedback
* Accepting responsibility and apologizing to those affected by our mistakes,
and learning from the experience
* Focusing on what is best not just for us as individuals, but for the
overall community
Examples of unacceptable behavior include:

advances of any kind
* Trolling, insulting or derogatory comments, and personal or political attacks
* Public or private harassment
* Publishing others' private information, such as a physical or email
address, without their explicit permission
* Other conduct which could reasonably be considered inappropriate in a
professional setting
## Enforcement Responsibilities
Community leaders are responsible for clarifying and enforcing our standards of
acceptable behavior and will take appropriate and fair corrective action in
response to any behavior that they deem inappropriate, threatening, offensive,
or harmful.
Community leaders have the right and responsibility to remove, edit, or reject
comments, commits, code, wiki edits, issues, and other contributions that are
not aligned to this Code of Conduct, and will communicate reasons for moderation
decisions when appropriate.
## Scope
This Code of Conduct applies within all community spaces, and also applies when
an individual is officially representing the community in public spaces.
Examples of representing our community include using an official e-mail address,
posting via an official social media account, or acting as an appointed
representative at an online or offline event.
## Enforcement
Instances of abusive, harassing, or otherwise unacceptable behavior may be
reported to the community leaders responsible for enforcement at
[email protected].
All complaints will be reviewed and investigated promptly and fairly.
All community leaders are obligated to respect the privacy and security of the
reporter of any incident.
## Enforcement Guidelines
Community leaders will follow these Community Impact Guidelines in determining
the consequences for any action they deem in violation of this Code of Conduct:
### 1. Correction
**Community Impact**: Use of inappropriate language or other behavior deemed
unprofessional or unwelcome in the community.
**Consequence**: A private, written warning from community leaders, providing
clarity around the nature of the violation and an explanation of why the
behavior was inappropriate. A public apology may be requested.
### 2. Warning
**Community Impact**: A violation through a single incident or series
of actions.
**Consequence**: A warning with consequences for continued behavior. No
interaction with the people involved, including unsolicited interaction with
those enforcing the Code of Conduct, for a specified period of time. This
includes avoiding interactions in community spaces as well as external channels
like social media. Violating these terms may lead to a temporary or
permanent ban.
### 3. Temporary Ban
**Community Impact**: A serious violation of community standards, including
sustained inappropriate behavior.
**Consequence**: A temporary ban from any sort of interaction or public
communication with the community for a specified period of time. No public or
private interaction with the people involved, including unsolicited interaction
with those enforcing the Code of Conduct, is allowed during this period.
Violating these terms may lead to a permanent ban.
### 4. Permanent Ban
**Community Impact**: Demonstrating a pattern of violation of community
standards, including sustained inappropriate behavior, harassment of an
individual, or aggression toward or disparagement of classes of individuals.
**Consequence**: A permanent ban from any sort of public interaction within
the community.

# Contributing to NCP
Thank you for your interest in contributing to the Natural Context Protocol (NCP) project! This document provides guidelines and information for contributors.
## Code of Conduct
This project follows a standard code of conduct. Be respectful, inclusive, and professional in all interactions.
## Development Workflow
### Prerequisites
- Node.js 18+ and npm
- TypeScript knowledge
- Familiarity with Jest testing framework
- Understanding of the Model Context Protocol (MCP)
### Setup
```bash
# Fork and clone the repository
git clone https://github.com/YOUR_USERNAME/ncp.git
cd ncp
# Install dependencies
npm install
# Run tests to ensure everything works
npm test
```
### Test-Driven Development
NCP follows strict TDD principles:
1. **Write tests first** - All new features must have tests written before implementation
2. **Red-Green-Refactor** - Follow the TDD cycle strictly
3. **High coverage** - Maintain 95%+ test coverage
4. **Integration tests** - Test component interactions, not just units
### Running Tests
```bash
# Run all tests
npm test
# Run tests in watch mode during development
npm test -- --watch
# Run specific test suites
npm test -- --testNamePattern="ProfileManager"
npm test -- --testNamePattern="CLI"
# Run with coverage report
npm run test:coverage
```
### Code Quality Standards
- **TypeScript Strict Mode**: All code must pass strict TypeScript checks
- **ESLint**: Follow the project's ESLint configuration
- **No Console Logs**: Use proper logging mechanisms in production code
- **Error Handling**: All async operations must have proper error handling
- **Resource Cleanup**: Always clean up resources (timeouts, connections, etc.)
### Commit Guidelines
Follow conventional commit format:
```
type(scope): description
Examples:
feat(cli): add new profile export command
fix(transport): resolve timeout cleanup issue
docs(readme): update installation instructions
test(orchestrator): add edge case coverage
```
**Commit Types:**
- `feat`: New features
- `fix`: Bug fixes
- `docs`: Documentation changes
- `test`: Test additions or modifications
- `refactor`: Code refactoring
- `perf`: Performance improvements
- `chore`: Maintenance tasks
### Pull Request Process
1. **Create a feature branch**:
```bash
git checkout -b feature/your-feature-name
```
2. **Write tests first**:
- Create comprehensive test cases
- Ensure tests fail initially (red phase)
3. **Implement your feature**:
- Write minimal code to pass tests (green phase)
- Refactor for quality and maintainability
4. **Ensure quality**:
```bash
# All tests must pass
npm test
# Code must compile without errors
npm run build
# Follow TypeScript strict mode
npm run typecheck
```
5. **Document your changes**:
- Update README if needed
- Add/update JSDoc comments
- Update CHANGELOG.md
6. **Submit pull request**:
- Clear title and description
- Reference any related issues
- Include test results
- Request review from maintainers
### Project Structure

├── core/ # Core orchestration and discovery
├── transport/ # MCP communication layers
├── profiles/ # Profile management system
├── discovery/ # Semantic matching algorithms
├── cli/ # Command-line interface
└── types/ # TypeScript type definitions

├── setup.ts # Jest configuration
└── jest-setup.ts # Environment setup
```
### Feature Development Guidelines
#### Adding New Transport Types
1. Create interface in `src/types/index.ts`
2. Implement transport in `src/transport/`
3. Add comprehensive tests
4. Update orchestrator to support new transport
5. Add CLI commands if needed
#### Extending Semantic Discovery
1. Add test cases in `src/discovery/semantic-matcher.test.ts`
2. Implement matching algorithms
3. Update confidence scoring mechanisms
4. Ensure backward compatibility
#### CLI Command Addition
1. Write CLI tests first in `src/cli/index.test.ts`
2. Implement command handlers
3. Add help documentation
4. Test error handling thoroughly
### Testing Guidelines
#### Unit Tests
- Test individual functions and methods
- Mock external dependencies
- Cover edge cases and error conditions
- Use descriptive test names
#### Integration Tests
- Test component interactions
- Verify end-to-end workflows
- Test real MCP server connections (when possible)
- Validate error propagation
#### Test Structure
```typescript
describe('ComponentName', () => {
beforeEach(() => {
// Setup for each test
});
afterEach(() => {
// Cleanup after each test
});
describe('feature description', () => {
it('should behave correctly in normal case', async () => {
// Test implementation
});
it('should handle error case gracefully', async () => {
// Error case testing
});
});
});
```
### Performance Considerations
- **Token Efficiency**: All features should maintain or improve token reduction
- **Memory Management**: Proper cleanup of resources and event listeners
- **Async Operations**: Use proper async/await patterns
- **Caching**: Consider caching strategies for expensive operations
### Security Guidelines
- **Input Validation**: Validate all external inputs
- **Path Security**: Prevent path traversal attacks
- **Process Security**: Secure child process spawning
- **Error Information**: Don't leak sensitive information in errors
### Documentation Standards
- **JSDoc Comments**: All public APIs must have JSDoc
- **README Updates**: Keep README synchronized with features
- **Example Code**: Provide working examples for new features
- **Architecture Docs**: Update architecture documentation for significant changes
### Getting Help
- **GitHub Issues**: For bugs and feature requests
- **GitHub Discussions**: For questions and general discussion
- **Code Review**: Maintainers will provide feedback on pull requests

Cursor IDE supports MCP servers via JSON configuration. Configure NCP once and access all your MCP tools through a unified interface.
---
## 🔧 Installation Steps
### 1. Install NCP
```bash
npm install -g @portel/ncp
```
### 2. Import Your Existing MCPs (Optional)
```bash
# If you have MCPs configured elsewhere, copy config to clipboard
# Then run:
ncp config import
```
### 3. Add MCPs to NCP
```bash
# Add your MCPs
ncp add filesystem npx @modelcontextprotocol/server-filesystem ~/Documents
ncp add github npx @modelcontextprotocol/server-github
ncp add brave-search npx @modelcontextprotocol/server-brave-search
# Verify
ncp list
```
### 4. Configure Cursor
**Config file location:**
- **macOS:** `~/Library/Application Support/Cursor/User/globalStorage/saoudrizwan.claude-dev/settings/cline_mcp_settings.json`
- **Windows:** `%APPDATA%/Cursor/User/globalStorage/saoudrizwan.claude-dev/settings/cline_mcp_settings.json`
- **Linux:** `~/.config/Cursor/User/globalStorage/saoudrizwan.claude-dev/settings/cline_mcp_settings.json`
**Edit the file:**
```bash
# macOS
nano ~/Library/Application\ Support/Cursor/User/globalStorage/saoudrizwan.claude-dev/settings/cline_mcp_settings.json
```
**Replace contents with:**
```json
{
"mcpServers": {
"ncp": {
"command": "ncp"
}
}
}
```
### 5. Restart Cursor
1. Quit Cursor completely (⌘Q on Mac, Alt+F4 on Windows)
2. Reopen Cursor
3. Start using NCP in your AI chat
---
## 🎯 Using NCP in Cursor
Ask your AI assistant:
- "List all available MCP tools"
- "Find tools to read files"
- "Execute filesystem:read_file on /tmp/test.txt"
---
## 🐛 Troubleshooting
**NCP command not found:**
```bash
npm install -g @portel/ncp
ncp --version
```
**Cursor doesn't see NCP:**
1. Verify config file path is correct for your OS
2. Check JSON syntax is valid
3. Restart Cursor completely
4. Check Cursor's developer console for errors
**NCP shows no MCPs:**
```bash
ncp list
# If empty, add MCPs:
ncp add filesystem npx @modelcontextprotocol/server-filesystem ~/Documents
```

# Installing NCP on Continue (VS Code Extension)
**Method:** JSON configuration only
---
## 📋 Overview
Continue is a VS Code extension that supports MCP servers via JSON configuration. Use NCP to consolidate all your MCP tools into a unified, intelligent interface.
---
## 🔧 Installation Steps
### 1. Install NCP
```bash
npm install -g @portel/ncp
```
### 2. Import Your Existing MCPs (Optional)
```bash
# If you have MCPs configured elsewhere, copy config to clipboard
# Then run:
ncp config import
```
### 3. Add MCPs to NCP
```bash
# Add your MCPs
ncp add filesystem npx @modelcontextprotocol/server-filesystem ~/Documents
ncp add github npx @modelcontextprotocol/server-github
ncp add memory npx @modelcontextprotocol/server-memory
# Verify
ncp list
```
### 4. Configure Continue
**Config file location:**
- **All platforms:** `~/.continue/config.json`
**Edit the file:**
```bash
nano ~/.continue/config.json
```
**Add NCP to the `experimental.modelContextProtocolServers` section:**
```json
{
"models": [...],
"experimental": {
"modelContextProtocolServers": {
"ncp": {
"command": "ncp"
}
}
}
}
```
> **Note:** Continue uses nested configuration under `experimental.modelContextProtocolServers`, not top-level `mcpServers`.
### 5. Restart VS Code
1. Close all VS Code windows
2. Reopen VS Code
3. Open Continue extension
4. Start using NCP
---
## 🎯 Using NCP in Continue
In Continue chat, ask:
- "List all available MCP tools"
- "Find tools for reading files"
- "Use NCP to discover GitHub tools"
---
## 🐛 Troubleshooting
**NCP command not found:**
```bash
npm install -g @portel/ncp
ncp --version
```
**Continue doesn't see NCP:**
1. Verify `~/.continue/config.json` has correct structure
2. Ensure NCP is under `experimental.modelContextProtocolServers`
3. Check JSON syntax is valid
4. Restart VS Code completely
5. Check Continue extension logs
**NCP shows no MCPs:**
```bash
ncp list
# If empty, add MCPs:
ncp add filesystem npx @modelcontextprotocol/server-filesystem ~/Documents
```
---
## 📝 Continue Config Format Reference
**Correct format:**
```json
{
"models": [
{
"title": "Claude 3.5 Sonnet",
"provider": "anthropic",
"model": "claude-3-5-sonnet-20241022",
"apiKey": "..."
}
],
"experimental": {
"modelContextProtocolServers": {
"ncp": {
"command": "ncp"
}
}
}
}
```
**⚠️ Note the nested structure:**
- `experimental` → `modelContextProtocolServers` → `ncp`
