OpenAPI MCP Server is a Model Context Protocol (MCP) server, mainly aimed at AI clients such as Claude Desktop and Cursor. Its core purpose is to enable AI to "browse through" complex OpenAPI specifications in simple language, thereby connecting to and operating any HTTP/REST API server.
Main capabilities:
- Obtain an overview of any OpenAPI specification.
- Retrieve detailed information about specific API operations.
- Support both JSON and YAML formats.
- Tested in Claude Desktop and Cursor.
- For other clients, the MCP URL can be used:https://openapi-mcp.openapisearch.com/mcp
How to use: This MCP works through a three-step process:
- Determine the required OpenAPI identifier.
- Request a summary of the specification in simple language.
- Determine which endpoints are needed and inspect exactly how they work (also in simple language).
The project description also mentions that the server can be run first, and then the MCP inspector.
Applicable scenarios: Suitable for developers who need to let an AI assistant understand and call HTTP/REST APIs based on OpenAPI v3 specifications, especially in scenarios where MCP is used for API exploration and integration in the Claude Desktop or Cursor environment.
Limitations: The materials do not provide detailed information about fees, pricing, platform compatibility, performance results, or specific installation commands.
