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