MCP Director

Centralized hub for managing MCP (Model Context Protocol) servers. Acts as a proxy/aggregator, providing a single entry point for AI clients (Claude Desktop, Claude Code, Cursor, etc.).

Key Features

Aggregation: Combine multiple MCP servers into one endpoint
Transports: Support for STDIO and HTTP (SSE) transports for clients
Access Control: Flexible profiles with white/black lists (glob patterns), rate limiting, and time restrictions
Projects: Ability to create different sets of servers for different projects
Web Interface: Integrated web interface for managing servers and viewing analytics
Analytics: Logging of all requests with performance metrics

Quick Start

Requirements

Rust (latest stable)
Node.js (required for web interface and some MCP servers)

Installation

cargo install --path apps/mcp-director-cli

Docker

docker-compose up -d

Running

mcp-director serve --config config/default.yaml

Global options: --json (machine-readable output), --dry-run (preview changes), --yes (auto-confirm).

Usage with Clients

Single Client Mode

For a single AI client, use serve directly:

Claude Desktop (claude_desktop_config.json):

{
  "mcpServers": {
    "director": {
      "command": "mcp-director",
      "args": ["serve"]
    }
  }
}

Multi-Client Mode

For multiple AI clients sharing the same MCP Director instance:

Step 1: Start the daemon:

mcp-director serve --no-stdio

Step 2: Configure clients to use connect:

Claude Desktop (claude_desktop_config.json):

{
  "mcpServers": {
    "director": {
      "command": "mcp-director",
      "args": ["connect", "--project", "my-project"]
    }
  }
}

Claude Code (.mcp.json):

{
  "mcpServers": {
    "director": {
      "command": "mcp-director",
      "args": ["connect", "--project", "my-project"]
    }
  }
}

HTTP Mode (Cursor, etc.)

Go to MCP settings in Cursor
Add a new server:
- URL: http://localhost:3000/sse
- Transport: SSE
- Optional: append ?project=your-project&profile=your-profile
