To use the OpenAPI MCP Server, install the package via pip, create a .env file with the required values for OPENAPI_SPEC_PATH and API_BASE_URL, and run the server using the command uv run openapi_mcp_server.

Supports HTTP API calls: GET, PUT, POST, PATCH. - Configurable environment variables for API interaction. - Easy installation and setup process.

Enabling LLMs to make API calls for data retrieval.
Integrating LLMs with existing REST APIs for enhanced functionality.
Facilitating automated testing of API endpoints using LLMs.
