How to Set Up and Use MCP Proxy Server

MCP Proxy Server is a central aggregation hub that consolidates multiple MCP resource servers into a single unified interface, enabling seamless multi-server access. Connect it to Claude to manage distributed MCP infrastructure and access capabilities from multiple backend servers through one connection point.

Prerequisites

  • Node.js 18+ installed
  • An MCP client such as Claude Desktop or Cursor
  • Git installed to clone the repository
  • One or more MCP servers to proxy
1

Clone the MCP Proxy repository

Get the latest code from GitHub since npm installation is not available.

git clone https://github.com/sparfenyuk/mcp-proxy
cd mcp-proxy
npm install
2

Configure the proxy server list

Create a configuration file specifying which MCP servers to aggregate.

{
  "servers": [
    {
      "name": "server1",
      "url": "http://localhost:3001"
    },
    {
      "name": "server2",
      "url": "http://localhost:3002"
    }
  ]
}
3

Build the MCP proxy server

Compile the proxy server code.

npm run build
4

Add to Claude Desktop configuration

Register the MCP Proxy Server in your MCP client config.

{
  "mcpServers": {
    "mcp-proxy": {
      "command": "node",
      "args": ["/path/to/mcp-proxy/dist/index.js", "--config", "/path/to/config.json"]
    }
  }
}
5

Verify proxy is running

Test that the proxy successfully aggregates all configured MCP servers.

curl http://localhost:3000/servers
6

Restart Claude Desktop

Close and reopen Claude Desktop to load the proxy server and access all aggregated tools.

How to register the MCP Proxy Server.

{
  "mcpServers": {
    "mcp-proxy": {
      "command": "node",
      "args": ["/path/to/mcp-proxy/dist/index.js", "--config", "/path/to/config.json"]
    }
  }
}

Prompts to Try

Example prompts for using the aggregated proxy.

- "Show me all available tools from all connected MCP servers."
- "Use the aggregated servers to get me information from multiple sources."
- "Query all backend servers simultaneously."

Troubleshooting MCP Proxy Server

Proxy cannot connect to backend MCP servers

Verify that all MCP servers in your config are running and accessible at the specified URLs. Check firewall rules and ensure ports are open.

Tools from aggregated servers don't appear in Claude

Restart Claude Desktop completely after updating the config. Check that the proxy server started successfully and that backend servers are responsive.

Proxy server crashes with out-of-memory errors

If you have many servers with many tools, the aggregation may consume significant memory. Consider running fewer servers or using a higher memory limit.
