常见问题

What prerequisites are needed to run the application?

Python 3.7+ and pip are required for local setup. For the `/openai` endpoint, an OpenAI API key must be set as an environment variable. Docker is optional for containerized deployment.

How do I set the OpenAI API key?

Export the key as the `OPENAI_API_KEY` environment variable before running the application locally (`export OPENAI_API_KEY=your_key_here`). For Docker, pass it using `-e OPENAI_API_KEY=your_key_here` when running the container.

What endpoints does the application expose?

`GET /` (hello world), `GET /hello/{name}` (personalized greeting), `GET /openai` (chat completion with optional `prompt` parameter), `GET /docs` (Swagger UI), and `GET /redoc` (ReDoc documentation).

How can I access the API documentation?

Open `/docs` in your browser for Swagger UI, or `/redoc` for ReDoc.

How do I use the MCP SSE support?

Start the server and connect using the MCP Inspector by running `npx @modelcontextprotocol/inspector` in your terminal.
