MCP Hub is the central registry for Model Context Protocol (MCP) servers — the open standard that enables AI assistants like Claude, GPT, and others to interact with external tools, databases, and services.
MCP Hub
The Largest Open MCP Server Directory
8,000+ community-driven MCP servers. Open-source, fully searchable, zero vendor lock-in.
What is MCP Hub?
MCP Hub is the largest open-source directory of Model Context Protocol (MCP) servers — the open standard that enables AI assistants like Claude, GPT, and others to interact with external tools, databases, and services.
Unlike closed registries, MCP Hub aggregates servers from 5+ sources and makes them freely searchable. No walled gardens, no gatekeeping — just a community-driven index of every MCP server we can find.
8,000+ servers · 15+ categories · 5 data sources · 100% open-source
Features
Discovery & Search
- Full-text search with PostgreSQL FTS + trigram matching
- Category browsing (Databases, APIs, Dev Tools, AI/ML, etc.)
- Filter by validation status and source
- Sort by stars, updated, or relevance
Multi-Source Indexing
We aggregate MCP servers from multiple sources to provide the most comprehensive directory:
| Source | Description | Link |
|:------:|:------------|:----:|
| MCP Registry | Official Model Context Protocol registry | registry.modelcontextprotocol.io |
| npm | Node.js packages with mcp keyword | npmjs.com |
| GitHub | Repositories with mcp-server topic | github.com/topics/mcp-server |
| Glama | Curated MCP servers from Glama.ai | glama.ai/mcp/servers |
| PulseMCP | Community MCP server directory | pulsemcp.com |
| PyPI | Python packages (coming soon) | — |
Server Validation
- Docker-based validation for secure sandbox testing
- MCP handshake verification with protocol compliance
- Capability discovery — tools, resources, prompts
- Community-assisted validation for servers requiring config
GitHub Integration
- Real-time stars & forks tracking
- Last commit timestamps
- Direct links to source repositories
- README rendering with syntax highlighting
Developer Experience
- One-click install commands (
npx,uvx) - Tools/Resources/Prompts documentation
- Responsive glassmorphism UI
- Command palette search (
Cmd+K)
Tech Stack
| Category | Technology | |:--------:|:-----------| | Framework | Next.js 16 (App Router) | | UI | React 19 + Tailwind CSS 4 | | Components | Radix UI + Lucide Icons | | Database | PostgreSQL via Neon (serverless) | | ORM | Drizzle ORM | | Auth | NextAuth.js v5 (GitHub OAuth) | | AI Parsing | Anthropic Claude | | Validation | Docker containers (Node.js/Python) |
Quick Start
Prerequisites
- Node.js 20+
- pnpm 9+
- PostgreSQL database (or Neon account)
- GitHub OAuth App (for authentication)
1. Clone & Install
git clone https://github.com/eL1fe/mcpdir.git
cd mcpdir
pnpm install
2. Environment Setup
cp .env.example .env.local
Configure your .env.local:
# Database (Neon recommended)
DATABASE_URL=postgresql://user:password@host/database?sslmode=require
# GitHub (for sync + OAuth)
GITHUB_TOKEN=ghp_xxxxxxxxxxxx
GITHUB_CLIENT_ID=your-oauth-app-client-id
GITHUB_CLIENT_SECRET=your-oauth-app-client-secret
# NextAuth
AUTH_SECRET=generate-with-openssl-rand-base64-32
# AI Parsing (optional - enhances metadata extraction)
ANTHROPIC_API_KEY=sk-ant-...
# or
OPENROUTER_API_KEY=sk-or-...
3. Database Setup
# Generate migrations
pnpm db:generate
# Apply migrations
pnpm db:push
# Seed categories
pnpm seed:categories
4. Sync Servers
# Sync from MCP Registry
pnpm sync
# Sync from all sources
pnpm sync:all
# With validation (requires Docker)
pnpm validate:popular
5. Run Development Server
pnpm dev
