mcp server router

proxy for remote mcp servers.

Quick Start

1. Get Remote MCP Server Key

go to MCP.so, select a hosting server,

click Connect to generate your exclusive server_key.

1. Configure MCP Server in any MCP Client

take Claude Desktop for example:

{
  "mcpServers": {
    "fetch": {
      "command": "npx",
      "args": ["-y", "mcprouter"],
      "env": {
        "SERVER_KEY": "xxx"
      }
    }
  }
}

Development

Install dependencies:

npm install

Build the server:

npm run build

For development with auto-rebuild:

npm run watch

Installation

To use with Claude Desktop, add the server config:

On MacOS: ~/Library/Application Support/Claude/claude_desktop_config.json On Windows: %APPDATA%/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "mcprouter": {
      "command": "/path/to/mcprouter/build/index.js"
    }
  }
}

Debugging

Since MCP servers communicate over stdio, debugging can be challenging. We recommend using the MCP Inspector, which is available as a package script:

npm run inspector

The Inspector will provide a URL to access debugging tools in your browser.
