FAQ from FastAPI Hello World Application

What dependencies are required?

Python 3.7+, pip, and an OpenAI API key (only for the /openai endpoint). Docker is optional.

How do I run the application?

Locally with uvicorn main:app --reload or python main.py. Docker: build the image and run the container with port 8000 mapped and the OPENAI_API_KEY environment variable.

Where does the data live?

The application does not persist any data; it only returns responses generated by its own endpoints or the OpenAI API.

What transports and authentication are used?

The MCP server uses SSE as its transport. The OpenAI endpoint requires the OPENAI_API_KEY to be set as an environment variable; no other authentication is needed.
