# Installing NCP on Claude Desktop
Claude Desktop offers **two ways** to install NCP. Choose the method that works best for you.
---
## 📦 Method 1: Extension Installation (.dxt) - **Recommended**
**Best for:** Most users who want one-click installation with automatic MCP detection.
### ✨ What You Get:
- ✅ **One-click installation** - Just drag and drop
- ✅ **Auto-import** - Automatically detects and imports ALL your existing Claude Desktop MCPs
- ✅ **Auto-sync** - Continuously syncs new MCPs on every startup
- ✅ **Zero configuration** - Works out of the box
### 📥 Installation Steps:
1. **Download the NCP Extension**
- Get the latest `.dxt` file: [ncp.dxt](https://github.com/portel-dev/ncp/releases/latest/download/ncp.dxt)
- File size: ~72MB (includes all dependencies)
2. **Install in Claude Desktop**
- **Option A:** Drag and drop `ncp.dxt` onto Claude Desktop window
- **Option B:** Double-click `ncp.dxt` file
- **Option C:** Open with Claude Desktop
3. **Verify Installation**
- Open Claude Desktop → **Settings** → **Extensions**
- You should see "**NCP - Natural Context Provider**" by **Portel**
- Status should show as **Enabled**
4. **Check Auto-Import**
```bash
# NCP automatically created profiles with your MCPs
cat ~/.ncp/profiles/all.json
```
You should see all your Claude Desktop MCPs imported with `_source: "json"` and `_client: "claude-desktop"`.
5. **Test NCP**
- Start a new chat in Claude Desktop
- Ask Claude: "List all available MCP tools using NCP"
- Claude should use NCP's `find` tool to discover your MCPs
### 🔄 How Auto-Import Works:
NCP automatically detects and imports MCPs from:
- ✅ **Claude Desktop config** (`claude_desktop_config.json`)
- ✅ **Claude Desktop extensions** (`.dxt` bundles in `Claude Extensions/` folder)
**When does auto-import run?**
- On first installation (imports all existing MCPs)
- On every startup (syncs any new MCPs)
- Runs in the background without interrupting your workflow
**What gets imported?**
```json
{
"mcpServers": {
"filesystem": {
"command": "npx",
"args": ["-y", "@modelcontextprotocol/server-filesystem", "~/Documents"],
"_source": "json",
"_client": "claude-desktop"
},
"github": {
"command": "npx",
"args": ["-y", "@modelcontextprotocol/server-github"],
"_source": ".dxt",
"_client": "claude-desktop"
}
}
}
```
### ⚙️ Extension Settings:
Configure NCP behavior in Claude Desktop → Settings → Extensions → NCP:
- **Profile Name** (default: `all`) - Which NCP profile to use
- **Configuration Path** (default: `~/.ncp`) - Where to store NCP configs
- **Auto-import Client MCPs** (default: `true`) - Automatically sync MCPs on startup
- **Enable Debug Logging** (default: `false`) - Show detailed logs for troubleshooting
### 🐛 Troubleshooting Extension Installation:
**Extension doesn't appear after installation:**
1. Restart Claude Desktop completely
2. Check Settings → Extensions to verify installation
3. Check logs: `~/Library/Logs/Claude/mcp-server-NCP - Natural Context Provider.log`
**NCP shows "Server disconnected" error:**
1. Check that NCP has permissions to create `~/.ncp/` directory
2. Verify Node.js is available (Claude Desktop includes built-in Node.js)
3. Check logs for specific error messages
**Auto-import didn't detect my MCPs:**
1. Verify MCPs exist in `~/Library/Application Support/Claude/claude_desktop_config.json`
2. Check `~/.ncp/profiles/all.json` to see what was imported
3. Enable debug logging in extension settings to see import process
---
## 🔧 Method 2: JSON Configuration - Manual Setup
**Best for:** Users who prefer traditional MCP configuration or need custom setup.
### When to Use This Method:
- ❌ You don't want the extension approach
- ✅ You prefer manual control over configuration
- ✅ You're using custom profile setups
- ✅ You're testing or developing NCP
### 📥 Installation Steps:
1. **Install NCP via npm**
```bash
npm install -g @portel/ncp
```
2. **Import Your Existing MCPs** (Optional)
```bash
# Copy your claude_desktop_config.json content to clipboard
# Then run:
ncp config import
```
NCP will auto-detect and import all MCPs from clipboard.
3. **Configure Claude Desktop**
Open `~/Library/Application Support/Claude/claude_desktop_config.json` and replace entire contents with:
```json
{
"mcpServers": {
"ncp": {
"command": "ncp"
}
}
}
```
4. **Restart Claude Desktop**
- Quit Claude Desktop completely
- Reopen Claude Desktop
- Start a new chat
5. **Verify Installation**
```bash
# Check NCP is working
ncp list
# Test tool discovery
ncp find "file operations"
```
### 🎯 Adding MCPs Manually:
After installation, add MCPs to NCP using the CLI:
```bash
# Add popular 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 they were added
ncp list
```
### 🔄 Managing MCPs:
```bash
# List all MCPs
ncp list
# Find specific tools
ncp find "read a file"
# Remove an MCP
ncp remove filesystem
# Test an MCP tool
ncp run filesystem:read_file --params '{"path": "/tmp/test.txt"}' --dry-run
```
### 🐛 Troubleshooting JSON Configuration:
**NCP command not found:**
```bash
# Reinstall globally
npm install -g @portel/ncp
# Verify installation
ncp --version
```
**Claude Desktop doesn't see NCP:**
1. Verify `claude_desktop_config.json` contains only the NCP entry
2. Restart Claude Desktop completely (Quit, not just close window)
3. Check Claude Desktop logs: `~/Library/Logs/Claude/mcp-server-ncp.log`
**NCP shows no MCPs:**
```bash
# Check configuration
ncp list
# Verify profile exists
cat ~/.ncp/profiles/all.json
# Add MCPs if empty
ncp add filesystem npx @modelcontextprotocol/server-filesystem ~/Documents
```

## 🆚 Comparison: Extension vs JSON
| Feature | Extension (.dxt) | JSON Config |
|---------|-----------------|-------------|
| **Installation** | Drag & drop | npm install + config edit |
| **Auto-import** | ✅ Automatic | ❌ Manual import |
| **Auto-sync** | ✅ On every startup | ❌ Manual updates |
| **CLI access** | ❌ Extension only | ✅ Full CLI available |
| **Configuration** | Settings UI | Terminal commands |
| **Best for** | Most users | Power users, developers |

# .mcpb Architecture Decision: Slim MCP-Only Runtime
## Executive Summary
**.mcpb is now a valuable installation option** thanks to a slim, MCP-only architecture that excludes CLI code. This provides real benefits for production deployments and power users while maintaining manual configuration workflows.
## The Problem We Solved
### Original Issue (User Insight)
User identified that .mcpb bundles used Claude Desktop's sandboxed Node.js, which couldn't provide CLI tools. This seemed like a fundamental blocker.
### The Breakthrough
**User's suggestion:** "If the MCPB is a slimmed down version, the performance of it will be much better."
Key insight: NCP reads from `~/.ncp/profiles/all.json` regardless of installation method. Users can manually edit JSON instead of using CLI tools.
## The Solution: Dual Entry Points
### Architecture
**For npm installation (full package):**
```
dist/index.js → imports dist/cli/index.ts → detects mode → runs MCP or CLI
```
**For .mcpb bundle (slim runtime):**
```
dist/index-mcp.js → directly runs MCP server (no CLI imports)
```
### Implementation
**Created: `src/index-mcp.ts`**
- Direct entry to MCP server
- No Commander.js, Inquirer.js, or CLI dependencies
- Minimal imports: just server, orchestrator, discovery
**Updated: `.mcpbignore`**
```
dist/cli/ # Exclude entire CLI directory
dist/index.js # Exclude full entry point
dist/index.js.map # Exclude source map
```
**Updated: `manifest.json`**
```json
{
"server": {
"entry_point": "dist/index-mcp.js" // Use slim entry point
}
}
```
## Results
### Bundle Size Comparison
| Metric | Before (Full) | After (Slim) | Improvement |
|--------|---------------|--------------|-------------|
| **Compressed** | 145 KB | **126 KB** | **13% smaller** ✅ |
| **Unpacked** | 547 KB | **462 KB** | **16% smaller** ✅ |
| **Files** | 48 | **47** | CLI removed ✅ |
### What's Excluded
❌ **CLI code excluded:**
- `dist/cli/` directory (entire CLI implementation)
- `dist/index.js` (full entry point)
- Commander.js, Inquirer.js dependencies (not loaded)
✅ **MCP code included:**
- `dist/index-mcp.js` (slim entry point)
- `dist/server/` (MCP server)
- `dist/orchestrator/` (NCP orchestration)
- `dist/discovery/` (RAG search, semantic matching)
- `dist/utils/` (shared utilities)
### Performance Benefits
1. **Faster Startup:** No CLI code parsing/loading
2. **Lower Memory:** Smaller code footprint
3. **Minimal Dependencies:** Only MCP runtime needs
## User Workflows
### Workflow A: .mcpb Only (Power Users)
```bash
# 1. Install .mcpb (double-click in Claude Desktop)
# Downloads 126KB bundle
# 2. Configure manually
nano ~/.ncp/profiles/all.json
```
```json
{
"mcpServers": {
"filesystem": {
"command": "npx",
"args": ["-y", "@modelcontextprotocol/server-filesystem", "/Users/name"]
},
"github": {
"command": "npx",
"args": ["-y", "@modelcontextprotocol/server-github"],
"env": { "GITHUB_PERSONAL_ACCESS_TOKEN": "ghp_xxx" }
}
}
}
```
```bash
# 3. Restart Claude Desktop → Works!
```
**Best for:**
- Power users comfortable with JSON
- Production/automation deployments
- Minimal footprint requirements
- Claude Desktop only
### Workflow B: npm Only (Full Package)
```bash
# 1. Install via npm
npm install -g @portel/ncp
# 2. Configure via CLI
ncp add filesystem npx -- -y @modelcontextprotocol/server-filesystem /Users/name
ncp add github npx -- -y @modelcontextprotocol/server-github
# 3. Works with all MCP clients
```
**Best for:**
- General users
- Multi-client setups (Claude Desktop, Cursor, Cline, etc.)
- Development environments
- Users who prefer CLI tools
### Workflow C: Both (Hybrid)
```bash
# 1. Install .mcpb for slim runtime in Claude Desktop
# 2. Install npm for CLI tools
npm install -g @portel/ncp
# 3. Use CLI to configure
ncp add filesystem ...
# 4. Claude Desktop uses slim .mcpb runtime
# 5. Other clients can use npm installation
```
**Best for:**
- Teams using multiple MCP clients
- Want slim runtime benefits + CLI convenience
## Comparison: NCP vs Other MCP Servers
| Aspect | Typical MCP (filesystem) | NCP (orchestrator) |
|--------|--------------------------|-------------------|
| **Configuration needed?** | No (self-contained) | Yes (must add MCPs) |
| **CLI tools needed?** | No | Optional (for convenience) |
| **Works after .mcpb?** | ✅ YES - Immediately | ✅ YES - After manual config |
| **.mcpb makes sense?** | ✅ YES - True one-click | ✅ YES - Slim runtime for power users |
## Why This Works Now
### Original Analysis (Incorrect)
❌ ".mcpb is fundamentally incompatible with NCP because it requires CLI tools"
### Corrected Analysis (After User Input)
✅ ".mcpb is valuable for NCP when:
1. Users manually configure `~/.ncp/profiles/all.json`
2. Bundle is optimized to exclude CLI code
3. Performance benefits justify manual configuration"
### The Key Difference
**Before:** Tried to make .mcpb bundle include CLI functionality (impossible due to sandboxing)
**After:** Made .mcpb a slim MCP-only runtime, accepted manual configuration as valid workflow
## Technical Details
### Entry Point Code
**src/index-mcp.ts:**
```typescript
#!/usr/bin/env node
import { MCPServer } from './server/mcp-server.js';
import { setOverrideWorkingDirectory } from './utils/ncp-paths.js';
// Handle --working-dir parameter
const workingDirIndex = process.argv.indexOf('--working-dir');
if (workingDirIndex !== -1) {
setOverrideWorkingDirectory(process.argv[workingDirIndex + 1]);
}
// Handle --profile parameter
const profileIndex = process.argv.indexOf('--profile');
const profileName = profileIndex !== -1 ? process.argv[profileIndex + 1] : 'all';
// Start MCP server (no CLI imports!)
const server = new MCPServer(profileName);
server.run().catch(console.error);
```
**Key:** No imports from `cli/`, no Commander.js, no interactive prompts.
### Build Process
```bash
# Build command (unchanged)
npm run build:mcpb
# What happens:
1. tsc compiles all TypeScript (including index-mcp.ts)
2. @anthropic-ai/mcpb pack creates bundle
3. .mcpbignore excludes dist/cli/ and dist/index.js
4. Result: 126KB bundle with only index-mcp.js + MCP code
```
### Verification
```bash
# Extract and verify bundle contents
unzip -l ncp-*.mcpb | grep "dist/"
# Should see:
# ✅ dist/index-mcp.js
# ✅ dist/server/
# ✅ dist/orchestrator/
# ❌ dist/index.js (excluded)
# ❌ dist/cli/ (excluded)
```
## Decision: Keep .mcpb with Slim Architecture
### Recommendation
✅ **KEEP and PROMOTE** .mcpb as a valid installation option with these benefits:
1. **Performance:** 13-16% smaller, faster startup
2. **Production:** Ideal for automation and deployment
3. **Power users:** Direct JSON control preferred by some
4. **Options:** Users can install npm separately if needed
### Documentation Strategy
1. **README.md:** Present both options equally
- .mcpb for Claude Desktop + manual config
- npm for CLI tools + all clients
2. **Guides:**
- Clear instructions for manual JSON configuration
- Examples of common MCP setups
- When to choose each method
3. **Messaging:**
- ✅ "Slim & Fast" (positive framing)
- ✅ "Power user option" (empowering)
- ❌ "Limited" or "Missing features" (negative framing)
## Lessons Learned
1. **Listen to user insights:** "Slimmed down version" suggestion was the breakthrough
2. **Challenge assumptions:** "Needs CLI" was wrong - manual config works fine
3. **Different workflows for different users:** Not everyone wants CLI tools
4. **Optimize for use case:** Production deployments benefit from minimal footprint
## Future Enhancements
1. **Web-based config tool:** GUI alternative to CLI and JSON editing
2. **Import from Claude Desktop:** Auto-migrate existing configs
3. **Profile templates:** Pre-configured profiles for common setups
4. **Auto-update:** In-app update mechanism for .mcpb bundles
## Files Modified
1. ✅ `src/index-mcp.ts` - New slim entry point
2. ✅ `manifest.json` - Use index-mcp.js
3. ✅ `.mcpbignore` - Exclude CLI code
4. ✅ `README.md` - Manual config examples
5. ✅ `docs/guides/mcpb-installation.md` - Complete guide
6. ✅ `MCPB-ARCHITECTURE-DECISION.md` - This document
## Conclusion
The .mcpb installation method is now a **valuable and performant option** for NCP users who:
- Use Claude Desktop exclusively
- Prefer manual configuration or automation
- Want the smallest, fastest runtime
- Are comfortable editing JSON
This architecture validates the user's insight that a slimmed-down version provides real benefits, while acknowledging that different users have different needs.

# Story-First Development Workflow
**How we build features at NCP: Story → Discussion → Code**
---
## 🎯 **Core Principle**
> "If you can't explain the feature as a story, you don't understand it well enough to build it."
Every feature must answer three questions:
1. **What pain does this solve?** (The Problem)
2. **How does NCP solve it?** (The Journey)
3. **Why does it matter?** (The Magic)
If you can't answer these clearly, the feature isn't ready.
---
## 📋 **The Complete Workflow**
### **Phase 1: Capture the Vision as a Story** ⏱️ 1-2 hours
1. **Open the template:** `.github/FEATURE_STORY_TEMPLATE.md`
2. **Fill in the story:**
- Start with "The Pain" (the user's frustration)
- Show "The Journey" (how NCP solves it)
- List "The Magic" (tangible benefits)
- Add technical details only if helpful
3. **Be specific:** Use real examples, not abstractions
4. **Be honest:** If pain isn't compelling, feature probably isn't needed
**Deliverable:** Draft story in `docs/stories/drafts/[feature-name].md`
---
### **Phase 2: Team Discussion** ⏱️ 30 minutes
1. **Share the story** in GitHub Discussion or team meeting
2. **Ask questions:**
- Is the pain real? Have we experienced it?
- Does the solution match the pain? Or is it over-engineered?
- Are benefits tangible? Can we measure them?
- What's missing from the story?
3. **Iterate:** Revise story based on feedback
4. **Make decision:**
- ✅ Approved → Move to Phase 3
- 🔄 Revise → Back to Phase 1
- 📅 Deferred → Add to backlog with reason
- ❌ Rejected → Document why (prevent rehashing later)
**Deliverable:** Approved story with decision notes
---
### **Phase 3: Story Becomes Spec** ⏱️ 30 minutes
1. **Extract requirements from story:**
- "The Pain" → Tells you what to fix
- "The Journey" → Tells you user flow
- "The Magic" → Tells you success criteria
- "What to Avoid" → Tells you scope boundaries
2. **Write test cases from story scenarios:**
- Before/after examples become tests
- "See It Yourself" section becomes integration test
3. **Define APIs from story language:**
- Story says "check MCP health" → `ncp health` command
- Story says "show broken MCPs" → `status: 'failed'` in output
**Deliverable:** Test plan + API design derived from story
---
### **Phase 4: Build Guided by Story** ⏱️ Hours to days
1. **Refer to story constantly:**
- Does this code solve the pain in the story?
- Does this match the journey described?
- Are we delivering the magic promised?
2. **Stop when story is satisfied:**
- Don't add features not in story
- Don't over-engineer beyond story needs
- Ship minimum lovable feature
3. **Update story if needed:**
- If implementation reveals better approach, update story first
- Don't let code drift from story
**Deliverable:** Working code that fulfills story
---
### **Phase 5: Story IS the Documentation** ⏱️ 15 minutes
1. **Move story from drafts to published:**
- `docs/stories/drafts/feature.md` → `docs/stories/XX-feature.md`
2. **Update README to reference story:**
- Add to story index
- Link from relevant sections
3. **Write release notes from story:**
- Use story's pain/magic sections
- Keep it compelling
**Deliverable:** Published story + updated README
---
### **Phase 6: Story IS the Marketing** ⏱️ 15 minutes
1. **Extract marketing copy from story:**
- Tweet: Pain + Magic in 280 chars
- Blog post: Full story with screenshots
- Release notes: Journey + Magic
2. **Share story link:**
- "Read the full story: docs/stories/XX-feature.md"
3. **Use story language everywhere:**
- Support docs
- Help text
- Error messages
**Deliverable:** Marketing materials derived from story
---
## ✅ **Quality Checklist**
Before moving to next phase, verify:
### **Story Quality:**
- [ ] Pain is relatable (I've felt this frustration)
- [ ] Journey is clear (non-technical person understands)
- [ ] Benefits are tangible (numbers, not vague claims)
- [ ] Language is simple (no jargon without explanation)
- [ ] Story is memorable (has an "aha!" moment)
### **Technical Quality:**
- [ ] Code fulfills story promise
- [ ] Tests based on story scenarios pass
- [ ] Performance matches story claims (if specified)
- [ ] Error messages use story language
- [ ] Help text references story
### **Documentation Quality:**
- [ ] Story published in `docs/stories/`
- [ ] README links to story
- [ ] Examples match story
- [ ] Screenshots show story journey
---
## 🚫 **Anti-Patterns to Avoid**
### **❌ Building First, Story Later**
**Wrong:**
```
Dev: "I built MCP versioning!"
PM: "Cool, but why?"
Dev: "Uh... it seemed useful?"
```
**Right:**
```
Dev: "Here's the story for MCP versioning..."
PM: "The pain isn't compelling. Let's skip it."
[Saves weeks of wasted work]
```
### **❌ Vague Story Language**
**Wrong:**
> "NCP improves MCP management with enhanced monitoring capabilities."
**Right:**
> "Your MCPs break silently. NCP's dashboard shows what's broken in one glance. Debug time: 20 min → 30 sec."
### **❌ Story Drift**
**Wrong:**
```
Story says: "Show MCP health status"
Code adds: Real-time graphs, email alerts, CSV export, historical data
[Scope explosion]
```
**Right:**
```
Story says: "Show MCP health status"
Code adds: Status list with colors
[Ships fast, matches story]
```
### **❌ Implementation Details in Story**
**Wrong:**
> "Uses Promise.all with AbortController for timeout handling..."
**Right:**
> "Checks each MCP in parallel, waits max 5 seconds per check."
---
## 📊 **Success Metrics**
You know story-first development is working when:
✅ **Features ship faster** (no scope creep, clear requirements)
✅ **Users understand benefits** (story makes value clear)
✅ **Documentation writes itself** (story is the docs)
✅ **Team alignment** (everyone understands "why")
✅ **Marketing is easy** (story gives you the words)
✅ **Less waste** (bad ideas rejected as stories, not built as code)
---
## 🎨 **Examples**
### **Example 1: Health Dashboard**
**Story:**
```markdown
## The Pain
MCPs break silently. You waste 20 min debugging every time.
## The Journey
Open dashboard. See:
- 🟢 filesystem: Healthy
- 🔴 github: FAILED (token expired)
Fix in 30 seconds.
## The Magic
- Debug time: 20 min → 30 sec
- Find failures before AI hits them
```
**What this told us:**
- ✅ Build: Status display with colors
- ✅ Build: Error detail view
- ❌ Skip: Historical graphs (not in story)
- ❌ Skip: Email alerts (different feature)
**Result:** Shipped in 2 days, exactly matches story promise.
---
### **Example 2: Clipboard Security**
**Story:**
```markdown
## The Pain
User: "Add GitHub with token ghp_123..."
[Secret now in AI chat, logs, training data]
## The Journey
1. AI shows: "Copy config to clipboard BEFORE clicking YES"
2. User copies: {"env":{"TOKEN":"secret"}}
3. User clicks YES
4. NCP reads clipboard (server-side)
5. AI never sees secret
## The Magic
- Secrets stay secret (not in chat/logs)
- Still convenient (no manual JSON editing)
```
**What this told us:**
- ✅ Build: Prompt with clipboard instructions
- ✅ Build: Server-side clipboard read
- ✅ Build: Merge clipboard config with base config
- ❌ Skip: Encrypted storage (not in story)
- ❌ Skip: Password manager integration (nice-to-have)
**Result:** Secure, simple, exactly what story promised.
---
## 🔗 **Resources**
- **Template:** `.github/FEATURE_STORY_TEMPLATE.md`
- **Examples:** `docs/stories/01-dream-and-discover.md`
- **Strategy:** `STORY-DRIVEN-DOCUMENTATION.md`
---
## 💬 **FAQs**
**Q: What if feature is too technical for a story?**
A: If you can't explain it to a non-technical user, maybe it's infrastructure (not a feature). Internal refactors don't need stories. User-facing features do.
**Q: Do bug fixes need stories?**
A: Small bugs: No. Major bugs affecting UX: Yes! Example: "Users lose data when NCP crashes" → Story about auto-save.
**Q: What if story changes during implementation?**
A: Update the story! If you discover better approach, revise story first, then build. Keep story and code in sync.
**Q: How long should stories be?**
A: 2-3 minutes reading time. If longer, you're probably describing multiple features. Split into separate stories.
**Q: Can we skip story for small features?**
A: Define "small". If it's user-facing and changes behavior, write the story. It takes 30 minutes and prevents miscommunication.
---
## 🎉 **The Promise**
**Follow this workflow, and you get:**
1. ✅ Features users actually want (pain validated upfront)
2. ✅ Clear requirements (story is the spec)
3. ✅ Great documentation (story is the docs)
4. ✅ Compelling marketing (story is the pitch)
5. ✅ Team alignment (everyone reads story)
6. ✅ Less waste (bad ideas rejected early)
**All from one effort: writing the story.**
---
**Story-first development: The most efficient way to build features users love.** 🚀

# Critical Issues Found - Empty Results & Re-Indexing
## Summary of Problems
1. ✅ **FOUND**: Cache profile hash is empty → triggers full re-index every time
2. ✅ **FOUND**: 41/46 MCPs are failing to index → keeps retrying them
3. ✅ **FOUND**: Race condition in handleFind → returns empty results during initialization
4. ✅ **FOUND**: Wrong response format → progress message not understood by AI
## Detailed Analysis
### Issue #1: Cache Profile Hash Empty (CRITICAL)
**Evidence:**
```bash
$ node check-cache.js
Profile has 52 MCPs
Current profile hash: d5b54172ea975e47...
Cached profile hash: empty... ← THIS IS THE PROBLEM!
Hashes match: false
Cached MCPs: 5
Failed MCPs: 41
```
**Root Cause:**
The cache metadata has `profileHash: ""` instead of the actual hash. This means:
- Every startup thinks the profile changed
- Triggers full re-indexing of all MCPs
- Invalidates perfectly good cache
**Location:** `src/cache/csv-cache.ts` or `src/cache/cache-patcher.ts`
**Impact:**
- User with 73 MCPs: re-indexes 46 every time (the ones not cached + failed ones)
- Takes 60+ seconds to become usable
- Wastes CPU/memory on redundant indexing
---
### Issue #2: 41 MCPs Failing to Index
**Evidence:**
```json
{
"failedMCPs": {
"postgres": "Connection closed",
"sqlite": "Connection closed",
... (39 more)
},
"indexedMCPs": {
"filesystem": "...",
"github": "...",
"docker": "...",
"kubernetes": "...",
"notion": "..."
}
}
```
**Root Cause:**
Most MCPs are failing during indexing with "Connection closed" errors.
**Possible Reasons:**
1. MCPs require environment variables that aren't set
2. MCPs have dependencies not installed
3. Timeout too aggressive
4. Connection pool exhaustion
**Impact:**
- Only 5/46 MCPs successfully indexed
- AI can only discover ~10% of installed tools
- Retry logic keeps trying failed MCPs → slow startup
---
### Issue #3: Race Condition in handleFind
**Flow:**
```typescript
// src/server/mcp-server.ts - handleFind()
if (!this.isInitialized && this.initializationPromise) {
const progress = this.orchestrator.getIndexingProgress();
if (progress && progress.total > 0) {
// Return progress message ✅
return progressMessage;
}
// ❌ PROBLEM: If progress is null or total=0, falls through!
// Wait 2 seconds
await timeout(2000);
}
// Try to find tools
const results = await finder.find(...);
if (results.length === 0) {
return "No tools found"; // ❌ AI sees this as "empty"
}
```
**Root Cause:**
Very early in initialization (<100ms), `indexingProgress` might not be set yet.
**What Perplexity Experiences:**
1. Call #1 (t=50ms): indexingProgress not set yet → waits 2s → "No tools found"
2. Call #2 (t=3s): indexing in progress → waits 2s → still no tools → "No tools found"
3. Call #3 (t=6s): still indexing → waits 2s → "No tools found"
4. Perplexity gives up
---
### Issue #4: Wrong Response Format
**Current Implementation:**
```typescript
return {
jsonrpc: '2.0',
id: request.id,
result: {
content: [{ type: 'text', text: progressMessage }]
}
};
```
**Problem:**
This is not a valid MCP `find` tool response format! The AI expects:
```typescript
result: {
tools: [...], // Array of tools
metadata: { ... }, // Optional metadata
message: "..." // Optional message
}
```
**What AI Sees:**
- Expected: `result.tools` array
- Got: `result.content[0].text` string
- Interprets as: Empty/invalid response
---
## Proposed Fixes
### Fix #1: Ensure Profile Hash is Saved
**File:** `src/cache/csv-cache.ts` or `src/cache/cache-patcher.ts`
**Change:**
```typescript
// When saving cache metadata
const metadata = {
version: '1.0',
profileName: this.profileName,
profileHash: this.currentProfileHash, // ← Make sure this is set!
createdAt: this.metadata.createdAt || new Date().toISOString(),
lastUpdated: new Date().toISOString(),
totalMCPs: validMCPs.length,
totalTools: toolCount,
indexedMCPs: this.indexedMCPHashes,
failedMCPs: this.failedMCPs
};
```
**Verify:** Check where `profileHash` gets computed and ensure it's included in metadata.
---
### Fix #2: Better Graceful Degradation
**File:** `src/server/mcp-server.ts`
**Change handleFind to ALWAYS return valid response:**
```typescript
public async handleFind(request: MCPRequest, args: any): Promise<MCPResponse> {
const isStillIndexing = !this.isInitialized && this.initializationPromise;
// Always try to return available tools
const finder = new ToolFinder(this.orchestrator);
const findResult = await finder.find({
query: args?.description || '',
page: args?.page || 1,
limit: args?.limit || 20,
depth: args?.depth || 2
});
const { tools, pagination } = findResult;
// Build metadata
const metadata: any = {
totalResults: pagination.totalResults,
page: pagination.page,
totalPages: pagination.totalPages
};
// If still indexing, add progress info to metadata
if (isStillIndexing) {
const progress = this.orchestrator.getIndexingProgress();
if (progress && progress.total > 0) {
metadata.indexingProgress = {
current: progress.current,
total: progress.total,
percentComplete: Math.round((progress.current / progress.total) * 100),
currentMCP: progress.currentMCP,
estimatedTimeRemaining: progress.estimatedTimeRemaining,
message: `Indexing ${progress.current}/${progress.total} MCPs. More tools will become available as indexing completes.`
};
}
}
return {
jsonrpc: '2.0',
id: request.id,
result: {
tools, // Always return what we have (even if empty)
metadata, // Include indexing status
message: metadata.indexingProgress?.message // Human-readable status
}
};
}
```
**Benefits:**
- AI always gets valid tool response structure
- Partial results returned immediately (from cached MCPs)
- Progress info in metadata for AI to understand situation
- No more "empty" responses
---
### Fix #3: Initialize Progress Earlier
**File:** `src/orchestrator/ncp-orchestrator.ts`
**Change:**
```typescript
async initialize(): Promise<void> {
// Set progress IMMEDIATELY before any async work
const allMCPs = Array.from(this.config.values());
this.indexingProgress = {
current: 0,
total: allMCPs.length,
currentMCP: 'initializing...'
};
// Then do the actual initialization work
const cached = await this.csvCache.loadFromCache();
const mcpsToIndex = allMCPs.filter(...);
this.indexingProgress.total = mcpsToIndex.length; // Update with accurate count
// Continue with indexing...
}
```
**Benefits:**
- Progress info available from t=0ms
- No race condition window
- AI always knows what's happening
---
### Fix #4: Investigate Failed MCPs
**Action Items:**
1. Add detailed logging for MCP failures
2. Classify failures:
- Missing env vars → show user what's needed
- Missing dependencies → show install instructions
- Broken config → show how to fix
- Actual bugs → file issues
3. Don't retry certain failures (missing deps) until config changes
4. Surface failures to user: `ncp list --show-failures`
---
### Fix #5: Cache Warming Strategy
**Idea:** Pre-index "core" MCPs on installation
```bash
# During npm postinstall
ncp init --index-common-mcps
```
Pre-index:
- filesystem
- fetch
- github
- puppeteer
- postgres (if available)
Store in global cache so first use is instant.
---
## Immediate Action Plan
### Priority 1 (Fixes empty results):
- [ ] Fix profile hash saving (Issue #1)
- [ ] Fix handleFind response format (Issue #2)
- [ ] Initialize progress earlier (Issue #3)
### Priority 2 (Improves UX):
- [ ] Investigate failed MCPs (Issue #4)
- [ ] Add `ncp list --show-failures` command
- [ ] Better error messages for AI
### Priority 3 (Nice to have):
- [ ] Cache warming
- [ ] Smart retry logic
- [ ] Health checks before indexing
---
## Testing Plan
### Test Case 1: Fresh Start
```bash
# Clear cache
rm -rf ~/.ncp/cache/*
# Start NCP via Claude Desktop
# Within 1 second, ask Claude to "list available MCP tools"
Expected:
- Returns partial results from 5 cached MCPs
- Metadata shows "Indexing 1/46 MCPs..."
- AI can use the 5 available tools immediately
```
### Test Case 2: Restart (Cache Should Work)
```bash
# Restart Claude Desktop
# Immediately ask "list available MCP tools"
Expected:
- Returns ALL tools instantly
- No re-indexing
- Response in <100ms
```
### Test Case 3: Failed MCPs
```bash
ncp list --show-failures
Expected output:
❌ 41 MCPs failed to index:
postgres: Missing environment variable DATABASE_URL
sqlite: Database file not found
...
💡 Run `ncp repair` to fix configuration issues
```
---
## Questions for User
1. **Which profile are you using with Perplexity?**
- all (0 MCPs)
- live-ecosystem (52 MCPs)
- Other?
2. **Why do 41 MCPs fail?**
- Are these real MCPs you want to use?
- Or test/example MCPs that should be removed?
3. **Do you want partial results?**
- Return 5 working tools immediately vs wait for all 46?
4. **Cache warming preference?**
- Pre-index common MCPs during install?
- Or index on-demand only?
```

# Release Process Improvements
## What Went Wrong (1.4.0 → 1.4.1 → 1.4.2 → 1.4.3)
### Root Cause: No Real-World Testing
We were testing **code in isolation** but never tested **the complete user experience**:
❌ Never tested: `npm install @portel/ncp@latest`
❌ Never tested: Running with Claude Desktop/Perplexity
❌ Never tested: Cache persistence across restarts
❌ Never tested: Real profile with 50+ MCPs
❌ Never tested: Rapid AI client calls during startup
### Bugs That Slipped Through
1. **Cache profileHash empty** → Full re-index every time (fixed in 50d872a)
2. **Race condition** → Empty results in <100ms window (fixed in 50d872a)
3. **Wrong default profile** → Used 'default' instead of 'all' (fixed in ae866ce)
4. **Package bloat** → Source maps, docs in npm package (fixed in 1.4.1-1.4.3)
5. **Version extraction bug** → Registry workflow assumed 'v' prefix (fixed in 1.4.2)
---
##What We've Implemented
### ✅ **60-Minute Pre-Release Checklist**
**Location:** `docs/guides/pre-release-checklist.md`
**Mandatory phases before EVERY release:**
1. **Code Quality** (5 min) - Tests pass, no obvious issues
2. **Package Verification** (5 min) - Inspect contents, check size
3. **Local Installation Test** (10 min) - Test published package behavior
4. **MCP Integration Test** (15 min) - **THE CRITICAL PHASE WE WERE MISSING**
- Test with actual MCP client simulation
- Verify cache profileHash, restart behavior
- Check response formats, partial results
5. **Performance & Resource Check** (5 min)
6. **Documentation Accuracy** (5 min)
7. **GitHub Checks** (5 min)
8. **Breaking Changes Review** (2 min)
9. **Release Prep** (5 min)
10. **Publish** (3 min)
11. **Announce** (5 min)
**STOP Gates - Release ONLY if:**
- ✅ All tests pass
- ✅ Package integrity verified
- ✅ **MCP integration works (find returns results, not empty)**
- ✅ Real-world test with Claude Desktop OR Perplexity
- ✅ Documentation up to date
---
### ✅ **Integration Test Infrastructure**
**Location:** `test/integration/mcp-client-simulation.test.cjs`
**What it tests:**
1. Initialize responds < 100ms
2. tools/list returns tools < 100ms (even during indexing)
3. find returns partial results during indexing (not empty)
4. Cache profileHash persists correctly
5. Second startup uses cache (no re-indexing)
**Run before release:**
```bash
npm run test:integration
```
**Current status:** Tests 1-2 pass, Tests 3-5 reveal timing issues (WIP)
---
### ✅ **Critical Bugs Fixed**
#### Fix #1: Cache Profile Hash (50d872a)
```typescript
// src/cache/csv-cache.ts
async startIncrementalWrite(profileHash: string): Promise<void> {
// Always update profile hash (critical for cache validation)
if (this.metadata) {
this.metadata.profileHash = profileHash; // ← FIX: Was only set for new caches
}
// ...
}
```
**Impact:** Prevents unnecessary full re-indexing on every startup
#### Fix #2: Race Condition (50d872a)
```typescript
// src/orchestrator/ncp-orchestrator.ts
async initialize(): Promise<void> {
// Initialize progress immediately to prevent race condition
this.indexingProgress = {
current: 0,
total: 0, // Updated once we know how many to index
currentMCP: 'initializing...'
}; // ← FIX: Was null during <100ms window
// ...
}
```
**Impact:** AI assistants see progress from t=0ms, not empty results
#### Fix #3: Partial Results During Indexing (50d872a)
```typescript
// src/server/mcp-server.ts
public async handleFind(request: MCPRequest, args: any): Promise<MCPResponse> {
const isStillIndexing = !this.isInitialized && this.initializationPromise;
// Always run finder to get partial results
const findResult = await finder.find({ query, page, limit, depth });
// Add indexing progress if still indexing
if (progress && progress.total > 0) {
output += `⏳ **Indexing in progress**: ${progress.current}/${progress.total} MCPs...\n`;
output += `📋 **Showing partial results** - more tools will become available.\n\n`;
}
// ← FIX: Was returning ONLY progress message, no tools
}
```
**Impact:** AI sees available tools immediately + knows more are coming
#### Fix #4: Default Profile Name (ae866ce)
```typescript
// src/orchestrator/ncp-orchestrator.ts
constructor(profileName: string = 'all', ...) { // ← FIX: Was 'default'
```
**Impact:** Respects user requirement - universal profile is 'all', not 'default'
---
## ⚠️ Outstanding Issues (Discovered by Integration Tests)
### Issue #1: Background Initialization Timing
**Problem:** Tests kill process before background `orchestrator.initialize()` completes
**Evidence:**
```bash
# Debug messages from CLI show profile selection works:
[DEBUG] Selected profile: integration-test
# But orchestrator debug messages NEVER appear:
[DEBUG ORC] Initializing with profileName: integration-test ← MISSING
# Because background init never completes before test exits
```
**Root Cause:**
```typescript
// src/server/mcp-server.ts
async initialize(): Promise<void> {
// Start initialization in the background, don't await it
this.initializationPromise = this.orchestrator.initialize().then(() => {
this.isInitialized = true;
});
// Return immediately ← Process may exit before this completes!
}
```
**Impact:**
- Cache may never be finalized if AI client disconnects quickly
- Short-lived connections don't benefit from caching
- Integration test can't verify cache persistence
**Proposed Fix:**
1. Add graceful shutdown handler to finalize cache before exit
2. OR: Make cache writes synchronous for critical metadata
3. OR: Ensure minimum process lifetime for cache finalization
---
### Issue #2: Integration Test Reliability
**Problem:** Tests 3-5 fail because background processes don't complete
**Options:**
1. **Simplify tests** - Focus only on what matters (empty results fixed?)
2. **Add wait logic** - Give processes time to finish before checking cache
3. **Mock background work** - Test synchronously for reliability
**Recommendation:** Option 1 for now - verify critical user issue is fixed, improve tests later
---
## Next Release Checklist (1.4.4)
### Must Do:
- [ ] **Run full pre-release checklist** (60 min - NO SHORTCUTS)
- [ ] **Phase 4 (MCP Integration)** - Test with Claude Desktop/Perplexity
- [ ] **Verify partial results** - AI sees tools during indexing
- [ ] **Manual cache check** - Verify profileHash persists
- [ ] **Test with live Perplexity** - Your original failing scenario
### Package Contents Verification:
```bash
npm pack --dry-run
# Must verify:
✓ dist/ included
✓ src/ excluded
✓ *.map excluded
✓ test/ excluded
✓ CLAUDE.md excluded
✓ Size < 500KB
```
### Real-World Test:
```bash
# Install latest from npm
cd /tmp/test-ncp
npm install @portel/ncp@latest
# Test with Perplexity
# 1. Add to Perplexity config
# 2. Restart Perplexity
# 3. Ask: "What MCP tools do you have?"
# 4. Expected: Tools listed within 2 seconds, not empty
# Test cache persistence
# 1. Restart Perplexity again
# 2. Check: cat ~/.ncp/cache/all-cache-meta.json | jq .profileHash
# 3. Expected: Non-empty hash, same as before
```
---
## Long-Term Improvements
### Automated E2E Testing (Next Sprint)
1. Docker container running Claude Desktop
2. Automated MCP interaction tests
3. Cache validation in CI/CD
4. Performance regression detection
### Release Automation (Next Month)
1. Pre-release checks as GitHub Action
2. Canary releases (publish with `@next` tag)
3. Automated rollback on test failures
4. Release notes generation from commits
### Quality Metrics
Track these per release:
- Time from 1st release to stable (goal: 1 version, not 4)
- Number of hotfixes needed (goal: 0)
- Package size (goal: < 500KB)
- Test coverage (goal: > 80%)
- Integration test pass rate (goal: 100%)
---
## Commitment Going Forward
**Zero Tolerance Policy:**
- ❌ No release without 60-minute checklist
- ❌ No release without Phase 4 (MCP Integration) passing
- ❌ No release without real-world test (Claude Desktop or Perplexity)
- ❌ No shortcuts under pressure
**Success Criteria:**
- ✅ Users install latest version, it works immediately
- ✅ Zero hotfixes after 1.4.4 release
- ✅ Cache works correctly, no re-indexing on restart
- ✅ AI assistants see tools within 2 seconds, not empty
- ✅ Users trust NCP as reliable infrastructure
**Your Feedback Integration:**
> "How will people trust us to use our product? These are all very basic stuff that needs to be tested before we make a release."
**Response:**
We've implemented a mandatory 60-minute pre-release process with real-world integration testing. The checklist is non-negotiable. Time investment upfront prevents 4+ hours of hotfix work and preserves user trust.
---
## How to Use This Document
**Before Every Release:**
1. Open `docs/guides/pre-release-checklist.md`
2. Follow EVERY step (60 min investment)
3. Don't skip Phase 4 (MCP Integration) - this is what we missed
4. If ANY test fails → fix before release
5. Update CHANGELOG.md with fixes
6. Only publish when ALL gates pass
**After This Release (1.4.4):**
1. Monitor user feedback for 48 hours
2. If zero issues → process works
3. If issues found → update checklist with new tests
4. Iterate and improve
**Remember:**
> A broken release costs 4+ hours of debugging + user trust.
> 60 minutes of testing is a bargain.
