MCP Openapi Overview

The saurav61091/mcp-openapi MCP server loads an OpenAPI 3.x specification and exposes its operations to MCP clients. It provides tools to list available endpoints and call an operation with path, query, header, and body parameters. Configuration supports local or remote JSON/YAML specs, endpoint filtering, server URL overrides, custom headers, and Bearer, API key, or Basic authentication. Use it when an API already has an OpenAPI specification and you want Claude or another compatible MCP client to access its endpoints without writing a custom integration.
