FastAPI
Expose your existing FastAPI endpoints as MCP tools. With Lunar.dev MCPX, the MCP Gateway for secure and governed tool access, you connect the FastAPI MCP server to Claude, ChatGPT, Cursor, and any MCP client through one gateway that routes, authenticates, and governs every FastAPI tool call against your policies.
Why MCPX
MCPX is Lunar.dev's MCP Gateway. It sits between your AI agents and your MCP servers as a single gateway for every tool call, routing, authenticating, and governing traffic against your policies. Connect FastAPI once and govern it everywhere: role-based access per agent with on-behalf-of attribution, real-time visibility, and an immutable audit trail of who did what, all deployable inside your own VPC.
Tools content
FastAPI MCP has no fixed tool set. It exposes whatever API routes your own FastAPI app chooses to expose as MCP tools, so the tools differ for every deployment and cannot be listed here.
