About MetaMCP
MetaMCP is an open-source MCP proxy that acts as an aggregator, orchestrator, middleware, and gateway, all packaged in a single Docker container. It allows users to dynamically combine multiple MCP servers into a unified MCP server, apply configurable middlewares (e.g., for observability and security), and expose them via SSE or Streamable HTTP endpoints with authentication. MetaMCP itself is a standard MCP server, making it easy to plug into any MCP client. It supports namespace grouping of servers, one-click endpoint switching, tool selection for remixing, and OIDC authentication for enterprise use.
