MCP Router

Minimal MCP Router built with Express.js for routing requests to multiple MCP agents.

Features

  • Health Check: GET /mcp/health returns {status:"ok"}
  • Agent Proxying: Routes /mcp/:agent/* requests to configured agent URLs
  • Configurable: Agent URLs configured via MCP_ROUTER_CONFIG environment variable

Installation

npm install

Configuration

Set the MCP_ROUTER_CONFIG environment variable with a JSON object mapping agent names to their URLs:

export MCP_ROUTER_CONFIG='{"agent1":"http://localhost:4001","agent2":"http://localhost:4002"}'

Usage

Start the server:

npm start

The server will listen on port 3000.

Endpoints

  • Health Check: GET http://localhost:3000/mcp/health

    • Returns: {"status":"ok"}

  • Agent Proxy: GET/POST/etc http://localhost:3000/mcp/:agent/*

    • Proxies requests to the configured agent URL
    • Example: GET /mcp/agent1/some/path → proxies to http://localhost:4001/some/path

Example

# Start the router with configuration
MCP_ROUTER_CONFIG='{"my-agent":"http://localhost:4001"}' npm start

# Check health
curl http://localhost:3000/mcp/health

# Proxy to agent
curl http://localhost:3000/mcp/my-agent/api/status

Error Handling

  • Returns 404 if agent is not configured
  • Returns 502 if proxy to agent fails
  • All errors return JSON responses with error details
