概要

What is Add API key to .env file?

A minimal MCP (Model Context Protocol) project that demonstrates how to set up an MCP server with an API key stored in a .env file. It uses DeepSeek as the LLM backend and includes sample Python and Node.js servers for task lists, weather, and stock data. Aimed at developers learning MCP.

How to use Add API key to .env file?

Create a .env file with OPENAI_API_KEY, OPENAI_BASE_URL, and OPENAI_MODEL (e.g., DeepSeek). Install dependencies with uv add mcp openai python-dotenv. Edit server.json to point to the server scripts (tasklist.py, weather.py, stock.js). Run the client with cd client && uv run client.py server.json.

Quickstart template for custom MCP server development.

よくある質問

What API key is required?

A DeepSeek API key (or any OpenAI‑compatible API) must be added to the `.env` file as `OPENAI_API_KEY`.

How do I switch to a different LLM service?

Change the `OPENAI_BASE_URL` and `OPENAI_MODEL` in `.env` to match the desired service.

What servers are provided?

The project includes `tasklist.py`, `weather.py`, and `stock.js` as example MCP servers.

How do I run the project?

Activate the virtual environment, then run `uv run client.py server.json` from the `client` directory.

Where does the data live?

Task data is stored in `tasks.csv` in the project root. Other server data comes from external APIs (not specified).
