概要

What is FastAPI Hello World Application?

It is a simple Hello World API built with FastAPI and MCP SSE support. It provides basic greeting endpoints and an endpoint for AI‑powered chat completions using OpenAI GPT‑4o.

How to use FastAPI Hello World Application?

Clone the repository, install dependencies, and set the OPENAI_API_KEY environment variable if using the OpenAI endpoint. Run locally with uvicorn main:app --reload or python main.py, or use Docker with docker build -t fastapi-hello-world . then docker run -p 8000:8000 -e OPENAI_API_KEY=your_key fastapi-hello-world.

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.

What are the known limits?

The /openai endpoint will fail if the OPENAI_API_KEY environment variable is not set. No other limitations are documented.
