Wolfram Alpha MCP Server

Wolfram Alpha answers two kinds of question a model should not answer from memory: things that need computing, and things that need a maintained reference — unit conversions, physical constants, population figures, dated statistics. The server passes a natural-language query to the API and returns the structured result, so the answer carries a source outside the model's weights. It is a small Python project built as a server plus a reference client, the latter driving Gemini through LangChain with a Gradio interface, which makes it a readable example of wiring a model to an MCP server end to end. A Wolfram Alpha AppID is required and goes in the environment; the free tier covers light interactive use.
