Overview

What is MetaMCP MCP Server?

MetaMCP MCP Server is a proxy server that joins multiple MCP servers into one. It fetches tool, prompt, and resource configurations from MetaMCP App and routes requests to the correct underlying server. It is compatible with any MCP client and provides a multi-workspaces layer for one-click switching between sets of MCP configurations.

How to use MetaMCP MCP Server?

Install via Smithery (npx -y @smithery/cli install @metatool-ai/mcp-server-metamcp --client claude) or manually by setting the METAMCP_API_KEY environment variable and running npx -y @metamcp/mcp-server-metamcp@latest. Configure the transport type (stdio, SSE, or streamable-http) and port using CLI options. Optionally, set METAMCP_API_BASE_URL for the MetaMCP API base URL.
