What mcpo does

Exposes an MCP server as an OpenAPI-compatible HTTP server, auto-generating interactive docs

Why teams reach for it: Converts MCP server commands into standard RESTful OpenAPI HTTP servers so their tools work with OpenAPI-compatible agents and applications.

Worth knowing

mcpo supports OAuth 2.1 authentication for MCP servers that require it. The implementation defaults to dynamic client registration, so most servers only need minimal configuration.

How will you route, mediate, and control traffic?

A gateway or proxy sits between clients and MCP servers to route traffic or add a control layer, without changing the servers themselves.
