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 :
[!IMPORTANT] OpenAPI MCP has found a new owner and has been migrated from v1.2 to v2, which works different to the previous version. You can still access any version prior to v2.0.0 and their README is here
OpenAPI MCP v2 is a Work In Progress and focuses on exploration and providing context about APIs. It does not allow executing the endpoints as tools directly, as authentication isn't a solved problem with MCP yet. However, it's great for codegen!
