# OpenAPI MCP Server [![janwilmake/openapi-mcp-server context](https://badge.forgithub.com/janwilmake/openapi-mcp-server?excludePathPatterns=*.yaml)](https://uithub.com/janwilmake/openapi-mcp-server?excludePathPatterns=*.yaml) A Model Context Protocol (MCP) server for Claude/Cursor that enables searching and exploring OpenAPI specifications through oapis.org. - Demo: https://x.com/janwilmake/status/1903497808134496583 - HN Thread: https://news.ycombinator.com/item?id=43447278 - OpenAPISearch: https://github.com/janwilmake/openapisearch - OAPIS: https://github.com/janwilmake/oapis 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](https://img.shields.io/badge/Install_MCP-OpenAPI%20MCP%20Server-1e3a8a?style=for-the-badge)](https://installthismcp.com/OpenAPI%20MCP%20Server?url=https%3A%2F%2Fopenapi-mcp.openapisearch.com%2Fmcp) For other clients, use MCP URL: https://openapi-mcp.openapisearch.com/mcp ## Local testing First run the server ``` wrangler dev ``` Then run the mcp inspector: ``` npx @modelcontextprotocol/inspector ```
