What is OpenAPI MCP Server?

OpenAPI MCP Server is an intelligent service that allows developers to explore and understand various OpenAPI specifications by interacting with AI assistants (such as Claude) in natural language. It can automatically identify the APIs you need, provide concise summaries, and explain in detail how specific endpoints work.

How to use OpenAPI MCP Server?

Simply install this service in a supported AI client (such as Claude Desktop or Cursor), and then ask questions in natural language. The system will automatically complete three steps: API identification, summary acquisition, and endpoint query.

Use cases

It is particularly useful when you need to quickly understand the functionality of an API or need detailed information about a specific endpoint. It is suitable for scenarios such as API integration development, learning new APIs, or generating API-related code.
