What Changed New Architecture Created an extensible client registry system that auto-imports MCPs from any MCP client, not just Claude Desktop: Supported clients: - Claude Desktop (JSON config + .mcpb extensions) - Enconvo (.mcpb extensions support) - Cursor (JSON config) - Cline (JSON config) - Continue (JSON config) Key Files Created 1. src/utils/client-registry.ts - Client definitions - Maps client names to config paths (macOS/Windows/Linux) - Defines config format (JSON/TOML) - Tracks extensions directory for .mcpb support 2. src/utils/client-importer.ts - Generic importer - importFromClient(clientName) - Imports from any registered client - Handles both config files AND extensions - Client-agnostic implementation How It Works 1. MCPServer receives initialize request ↓ 2. Extracts clientInfo.name (e.g., "Claude Desktop", "Cursor") ↓ 3. Calls orchestrator.triggerAutoImport(clientName) in background ↓ 4. ProfileManager.tryAutoImportFromClient(clientName) ↓ 5. Client-agnostic importer: - Looks up client in registry - Reads config file (JSON/TOML) - Scans extensions directory (.mcpb bundles) - Finds missing MCPs (diff with NCP profile) - Imports using addMCPToProfile() for cache coherence Benefits ✅ Auto-import from ANY client (not hardcoded to Claude Desktop)✅ Detects client via MCP spec (clientInfo.name in initialize request)✅ Runs in background (non-blocking)✅ Extensible - Easy to add new clients to registry✅ Cache coherence maintained - Uses internal add command Example Output MCP client identified: Claude Desktop 1.2.0 ✨ Auto-synced 3 new MCPs from Claude Desktop: - 2 from config file - 1 from extensions → Added to ~/.ncp/profiles/all.json > lets find which clients support mcpb ⏺ Web Search(".mcpb MCP bundle format which clients support 2025") ⎿ Did 1 search in 25s ⏺ Web Search("Enconvo .mcpb bundle support MCP extensions") ⎿ Did 1 search in 21s ⏺ Web Search("anthropic .mcpb specification MCP bundle client support") ⎿ Did 1 search in 21s ⏺ Fetch(https://github.com/anthropics/mcpb) ⎿ Received 321.5KB (200 OK) ⏺ Fetch(https://docs.enconvo.com/docs/features/model-context-protocol) ⎿ Received 17.1KB (200 OK) ⏺ Web Search("Enconvo Extensions directory MCP server installation location macOS") ⎿ Did 5 searches in 38s ⏺ Web Search(""Enconvo" "Application Support" MCP configuration file location") ⎿ Did 6 searches in 38s ⏺ Based on my research, here's what I found about .mcpb support: ✅ Confirmed .mcpb Support Claude Desktop (macOS & Windows) - Native .mcpb bundle support - Extensions stored in: ~/Library/Application Support/Claude/Claude Extensions/ - Uses manifest.json format - One-click installation ❓ Unknown - Needs Verification Enconvo - Has MCP support with one-click installation via MCP Store - Documentation doesn't mention .mcpb format specifically - Likely uses JSON config instead of .mcpb bundles - Need to check if Extensions directory exists ❌ No .mcpb Support (Use JSON Config) Cursor, Cline, Continue, VS Code - Use JSON/TOML configuration files - No .mcpb bundle support mentioned - Manual MCP server configuration --- Let me check your system to see if Enconvo actually supports .mcpb: ⏺ Bash(ls -la ~/Library/Application\ Support/ | grep -i enconvo) ⎿ ls: ~/Library/Application Support/: No such file or directory ⏺ Bash(ls -la "$HOME/Library/Application Support/" | grep -i enconvo) ⎿ No matches found ⏺ Bash(find "$HOME/Library" -name "*enconvo*" -o -name "*Enconvo*" 2>/dev/null | head -20) ⎿ (No content) ⏺ No Enconvo installation found on your machine. Based on research, here's the confirmed .mcpb support status: Summary | Client | .mcpb Support | Config Location | Notes | |----------------|---------------|---------------------------------------|-------------------- --------------------| | Claude Desktop | ✅ Confirmed | ~/Library/Application Support/Claude/ | Extensions in Claude Extensions/ | | Enconvo | ❓ Unknown | Not documented | Has MCP store, but no .mcpb docs found | | Cursor | ❌ No | JSON config | Uses cline_mcp_settings.json | | Cline | ❌ No | JSON config | Uses cline_mcp_settings.json | | Continue | ❌ No | JSON config | Uses ~/.continue/config.json | Recommendation: Update our client registry to: 1. Only set extensionsDir for Claude Desktop (confirmed) 2. Remove extensionsDir from Enconvo until verified 3. Keep other clients as config-only Should I update src/utils/client-registry.ts to reflect only confirmed information? > Nconvo is not a regular MCP client per se and the users may be limited so we don't have to bother about it. But when I opened the .dxt file, it initially opened in that. That's how I know it supports that. ⏺ Got it! So Enconvo does support .mcpb (you confirmed it opens .dxt files), but it has limited users and isn't a priority MCP client. Let me update the client registry to focus on the major clients: ⏺ Update(src/utils/client-registry.ts) ⎿ Updated src/utils/client-registry.ts with 2 additions and 19 removals 41 export const CLIENT_REGISTRY: Record<string, ClientDefinition> = { 42 /** 43 * Claude Desktop (Anthropic) 44 - * Supports both JSON config and .mcpb extensions 44 + * PRIMARY CLIENT: Supports both JSON config and .mcpb extensions 45 + * Most widely used MCP client with native .mcpb bundle support 46 */ 47 'claude-desktop': { 48 displayName: 'Claude Desktop', ... 60 }, 61 62 /** 63 - * Enconvo 64 - * Also supports .mcpb extensions 65 - */ 66 - 'enconvo': { 67 - displayName: 'Enconvo', 68 - configPaths: { 69 - darwin: '~/Library/Application Support/Enconvo/config.json', 70 - // TODO: Verify Windows/Linux paths 71 - }, 72 - configFormat: 'json', 73 - extensionsDir: { 74 - darwin: '~/Library/Application Support/Enconvo/Extensions', 75 - // TODO: Verify Windows/Linux paths 76 - }, 77 - mcpServersPath: 'mcpServers' // TODO: Verify actual path in config 78 - }, 79 - 80 - /** 63 * Cursor (IDE) 64 * Uses JSON config in VS Code-like structure 65 */ ⏺ Bash(npm run build) ⎿ > @portel/[email protected] build > tsc && chmod +x dist/index.js ⏺ ✅ Updated and focused on major clients! Final Client Registry Supported clients for auto-import: | Client | .mcpb Bundles | Config Format | Priority | |----------------|---------------|---------------|-----------| | Claude Desktop | ✅ Yes | JSON | ⭐ PRIMARY | | Cursor | ❌ No | JSON | High | | Cline | ❌ No | JSON | High | | Continue | ❌ No | JSON | Medium | Removed: Enconvo (limited user base, not a priority) How It Works Now User launches NCP from any client ↓ Client sends MCP initialize with clientInfo.name ↓ NCP detects client and triggers auto-import: • Claude Desktop → JSON config + .mcpb extensions • Cursor/Cline/Continue → JSON config only ↓ Missing MCPs auto-synced to NCP profile The registry is easily extensible - when new clients add .mcpb support, just add extensionsDir to their definition. > See with NPM, good thing is when people install NCP, I know how many downloads have happened because NPM is tracking that. If I go by the new way, which is the Dxt How do I know how many downloads happened and all? ⏺ Excellent question! Here are your options for tracking .mcpb adoption: 1. GitHub Release Download Stats (Built-in, Free) GitHub automatically tracks download counts for release assets: https://github.com/portel-dev/ncp/releases/latest └── ncp.mcpb (Download count visible publicly) Pros: - ✅ Automatic, no code needed - ✅ Public transparency - ✅ Shows download trends over time Cons: - ❌ Only tracks downloads, not actual installs - ❌ No demographic data (OS, version, etc.) - ❌ Can't distinguish unique users vs re-downloads How to view: - GitHub UI shows download counts per release asset - GitHub API: https://api.github.com/repos/portel-dev/ncp/releases 2. Anonymous Telemetry (Requires Implementation) Add opt-in usage tracking to the .mcpb bundle: // On first run or daily ping if (userConsent) { sendAnonymousMetrics({ installId: generateUUID(), // Unique per installation version: '1.4.3', platform: 'darwin', clientName: 'claude-desktop', mcpCount: 5, // Number of MCPs configured timestamp: Date.now() }); } Options: - Self-hosted analytics (Plausible, Umami, Matomo) - Cloud services (PostHog, Mixpanel, Amplitude) - Simple HTTP endpoint logging to your server Pros: - ✅ Tracks actual usage, not just downloads - ✅ Demographics (OS, client type, MCP usage patterns) - ✅ Engagement metrics (DAU/MAU, retention) Cons: - ❌ Requires backend infrastructure - ❌ Privacy concerns (must be opt-in, GDPR compliant) - ❌ Implementation effort 3. Hybrid Approach (Recommended) Track both channels separately: | Metric | NPM | .mcpb (GitHub Releases) | |-------------------|--------------|-------------------------| | Downloads | npm stats | GitHub release stats | | Active installs | npm registry | Telemetry (opt-in) | | User demographics | Limited | Telemetry (opt-in) | Strategy: 1. Short term: Use GitHub release download stats (free, immediate) 2. Medium term: Add opt-in telemetry for better insights 3. Long term: Both npm + .mcpb contribute to total adoption metrics 4.

Your options: 1. GitHub Release Stats (Zero effort) node scripts/check-mcpb-downloads.js Shows download counts per release - similar to npm stats, but only downloads (not actual usage). 2. Opt-In Telemetry (Better insights) See docs/guides/telemetry-design.md for full design. Key benefits: - Track actual active installs, not just downloads - See platform breakdown (macOS/Windows/Linux) - Understand MCP client distribution (Claude Desktop vs Cursor vs others) - Measure retention (how many users keep using NCP) Privacy-first approach: - Completely opt-in - Anonymous UUID, no personal data - Open source implementation - Users can audit what's collected 3. Hybrid Approach (Recommended) Track both channels: - npm downloads: Automatic via npm registry - .mcpb downloads: GitHub release stats (automatic) - Active usage: Optional telemetry (if you implement it) Total adoption = npm downloads + .mcpb downloads --- I created two files to help you decide: 1. scripts/check-mcpb-downloads.js - Check GitHub stats right now 2. docs/guides/telemetry-design.md - Complete privacy-first telemetry design Want me to implement the telemetry system, or stick with GitHub stats for now? > See, what I want is the users to see that so many downloads have happened to build credibility.

I mean, when the user does not specify a profile, the MCPs are added into the universal profile called all. And if they add to any specific profile, that time also it will add the same MCP if it is not already present into all profile also. ⏺ Let me check the profile policy implementation across the codebase. ⏺ Search(pattern: "addMCPToProfile|add.*profile", path: "src") ⎿ Found 4 files (ctrl+o to expand) ⏺ Search(pattern: "ncp add|--profile", path: "src/cli/index.ts", output_mode: "content") ⎿ Found 131 lines (ctrl+o to expand) ⏺ Read(src/cli/index.ts) ⎿ Read 80 lines (ctrl+o to expand) ⏺ Read(src/cli/index.ts) ⎿ Read 80 lines (ctrl+o to expand) ⏺ Read(src/cli/index.ts) ⎿ Read 50 lines (ctrl+o to expand) ⏺ Read(src/profiles/profile-manager.ts) ⎿ Read 80 lines (ctrl+o to expand) ⏺ Search(pattern: "importConfig|import.*profile", path: "src/utils/config-manager.ts", output_mode: "content") ⎿ Found 87 lines (ctrl+o to expand) ⏺ Search(pattern: "processImportData", path: "src/utils/config-manager.ts", output_mode: "content") ⎿ Found 125 lines (ctrl+o to expand) ⏺ Read(src/utils/config-manager.ts) ⎿ Read 60 lines (ctrl+o to expand) ⏺ Read(src/cli/index.ts) ⎿ Read 30 lines (ctrl+o to expand) ⏺ Let me create a comprehensive analysis of the "all" profile policy: ⏺ Analysis: "all" Profile Policy Implementation I've analyzed the codebase. Here's what I found: ✅ What Works Correctly 1. ncp add command (src/cli/index.ts:470) ncp add foo npx bar # Defaults to --profiles all ✅ ncp add foo npx bar --profiles dev # Adds only to 'dev' ❌ (no sync to 'all') 2. Runtime merging (src/profiles/profile-manager.ts:176-204) async getProfile(name: string): Promise<Profile | undefined> { if (name === 'all') { // SMART: Merges 'all' + all other profiles at runtime const mergedServers = { ...allProfile.mcpServers }; for (const [profileName, profile] of this.profiles) { if (profileName !== 'all') { for (const [mcpName, mcpConfig] of Object.entries(profile.mcpServers)) { if (!mergedServers[mcpName]) { mergedServers[mcpName] = mcpConfig; } } } } return { ...allProfile, mcpServers: mergedServers }; } } 2. Result: When you read 'all' profile, it includes MCPs from ALL profiles! ✅ 3. Auto-import (src/profiles/profile-manager.ts:62) await this.addMCPToProfile('all', name, cleanConfig); // ✅ Adds to 'all' ❌ Bugs Found 1. ncp config import wrong default (src/utils/config-manager.ts:89) async importConfig(filePath?: string, profileName: string = 'default', dryRun: boolean = false) // ^^^^^^^^^ BUG! Should be 'all' 1. CLI says: '--profile <name>', 'Target profile (default: all)'Actual default: 'default' (when options.profile is undefined) 🤔 Current Policy Behavior | Command | What Happens | Appears in 'all'? | |------------------------------------|--------------------------|---------------------------| | ncp add foo npx bar | Adds to 'all' physically | ✅ Yes | | ncp add foo npx bar --profiles dev | Adds to 'dev' only | ✅ Yes (via runtime merge) | | ncp config import | Adds to 'default' (!!) | ✅ Yes (via runtime merge) | | Auto-import (Claude Desktop) | Adds to 'all' physically | ✅ Yes | 📋 Your Question: "When user adds to any specific profile, should it ALSO add to 'all' profile physically?" Current answer: NO. It relies on runtime merging. This means: - ~/.ncp/profiles/all.json - Contains only MCPs added directly to 'all' - ~/.ncp/profiles/dev.json - Contains MCPs added to 'dev' - When you load 'all' profile → You get both (merged) --- 🎯 What Should the Policy Be? Option A: Current (Runtime Merge Only) ncp add foo npx bar --profiles dev → dev.json gets foo → all.json stays unchanged → Reading 'all' includes foo (runtime merge) Option B: Physical Sync to 'all' ncp add foo npx bar --profiles dev → dev.json gets foo → all.json ALSO gets foo (if not present) → Reading 'all' includes foo (physical storage) Which policy do you want? The current implementation uses Option A (runtime merge), which is actually smart because: - 'all' automatically stays in sync - No duplicate storage - Simpler code But we need to fix: 1. ❌ ncp config import defaulting to 'default' instead of 'all' Should I fix this bug and keep the runtime merge approach, or do you want Option B (physical sync)? > Let us keep the runtime merge feature, but we need to fix the issues where we are mapping to default and all. This issue pops up every now and then. How do I make sure it doesn't happen that time? The code do we have to comment? saying "Do not change the name. It has to be like this kind of so that when you work on it next time you remember do not change it" to default and all. ⏺ Perfect! Let me find all the places where profile defaults are set and add strong warning comments to prevent this bug from recurring. ⏺ Search(pattern: "profileName.*=.*['\"]all['\"]|profileName.*=.*['\"]default['\"]|profile.*default. *all|profile.*all.*default", path: "src", output_mode: "content") ⎿ Found 114 lines (ctrl+o to expand) ⏺ Found the issues!

Arguments FOR exposing management via MCP: - AI could add/remove MCPs dynamically - AI could repair broken configurations - AI could import configs from clipboard Arguments AGAINST: - Security risk (AI modifying MCP configuration) - Complexity (requires write permissions) - Use case unclear (why would AI manage MCPs?) Current approach is sound: MCP server is read-only discovery + execution, CLI is full management. --- 🎯 Recommendation Keep current parity but consider: 1. Improve find listing mode to match ncp list richness: find({ mode: 'list-mcps', // New mode show_health: true, show_versions: true }) 2. Add read-only introspection: // New tool: get_mcp_info get_mcp_info({ mcp_name: "filesystem" }) // Returns: version, description, tool count, health status 3. Keep management in CLI only - safer and more appropriate. Current parity is GOOD - core operations work, management stays secure in CLI. ✅ ```
