MCP Proxy Server

MCP Proxy Server

An MCP proxy that aggregates multiple MCP servers behind a single HTTP entrypoint.

Features

• Proxy multiple MCP clients: aggregate tools, prompts, and resources from many servers.
• SSE and streamable HTTP: serve via Server‑Sent Events or streamable HTTP.
• Flexible config: supports stdio, sse, and streamable-http client types.
• OAuth client support: authorize once against downstream servers that require interactive OAuth (e.g. Notion), then let the proxy hold and refresh the token for every caller.
