Strompreis MCP is a Python package that lets AI agents like Claude or any MCP-compatible assistant access real-time German electricity price forecasts. Strompreis is German for electricity price. The data comes from SMARD, the official German electricity market data platform run by the federal network agency. A background collector fetches new prices every fifteen minutes and stores them in a local SQLite database. The MCP server reads from that database and exposes three tools. The first tool returns a price forecast for the next one to seventy-two hours as a JSON array with timestamps, prices in cents per kilowatt-hour, a confidence indicator, and a flag for peak hours. The second tool returns a plain-text recommendation of the cheapest hours within a window, phrased so an AI can read it directly back to a user. The third tool reports the health of the local database. Practical examples in the README show an AI agent answering questions like when to run the dishwasher, whether to charge an electric car now or wait, and what the forecast looks like for tomorrow. The agent calls the appropriate tool and returns a specific, time-stamped answer. Setup involves installing the package with pip, running a setup script to initialize the database and collect the first data, and adding the server to your Claude Desktop or Cline configuration. The collector should be scheduled with a cron job to refresh every fifteen minutes. The package also includes a small website component that calculates potential savings from switching to a dynamic electricity tariff. The project is licensed under MIT.
