OpenAPI MCP Server

janwilmake/openapi-mcp-server context

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:

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

Features

  • Get an overview of any OpenAPI specification
  • Retrieve details about specific API operations
  • Support for both JSON and YAML formats
  • Tested with Claude Desktop and Cursor

Installation

Install OpenAPI MCP Server

For other clients, use MCP URL: https://openapi-mcp.openapisearch.com/mcp

Local testing

First run the server

wrangler dev
