How do I install Openapi?

You can install Openapi using pip: `pip install openapi_mcp_server`. Then configure it by setting environment variables like `OPENAPI_SPEC_PATH` and `API_BASE_URL`.

How can I configure Openapi?

Openapi is configured primarily through environment variables. You can specify the OpenAPI specification path, API base URL, headers, whitelist/blacklist operation IDs, and proxy settings via environment variables.

What credentials does it need?

It reads `DEBUG`, `API_BASE_URL`, `OPENAPI_SPEC_PATH`, `API_HEADERS`, `API_WHITE_LIST`, `TWINE_USERNAME` from the environment. Store these in your client's env block or a secrets manager — never commit them to a repository — and grant the narrowest scope that still covers your use case.
