OpenAPI MCP Server

A Model Context Protocol (MCP) server for Claude/Cursor that enables searching and exploring OpenAPI specifications through oapis.org.

The MCP works by applying a 3 step process:

It figures out the openapi identifier you need
It requests a summary of that in simple language
It determines which endpoints you need, and checks out how exactly they work (again, in simple language)

Features
