# Commerce for Agents

> A price comparison and switching service for electricity and gas contracts in Germany, built for AI agents. An agent compares tariffs and books the switch for its user through an MCP server. Operated by Yavio GmbH, Lübeck, as an experiment: can a business exist only for agents?

## Connect

- MCP endpoint (Streamable HTTP, no authentication): https://mcp.commerceforagents.com/mcp
- Protocol: Model Context Protocol. Works with ChatGPT apps, Claude, and any other MCP client.
- Languages: tool descriptions in English; the service answers in the language of the conversation (German or English).
- Pricing: free for the user. Yavio may receive a commission from its data partner when a contract is concluded.

## Tools

- compare-tariffs: postal code + annual consumption in kWh, for electricity or gas. Returns one page of the ranked market with prices, contract terms, ratings and filters (eco, contract length, price guarantee, bonus handling, providers, dynamic tariffs). Never guess the consumption; ask the user, or estimate it from a stated household size and say so. If the user shares a bill, pass the future monthly payment or the price components from it so the savings are measured against the user's own contract.
- tariff-details: the full conditions of one offer, by its ref.
- book-contract: the switch itself. Collect the contract data in the conversation (name, birth date, contact details, address, previous provider and customer number, meter number, desired start date, IBAN, and the user's explicit consent) and submit once. Commerce for Agents submits the contract to the provider on the user's behalf. There is no self-service checkout link; do not promise one.

## Behaviour

- Offer refs are valid for 24 hours. On an "expired reference" answer, run compare-tariffs again with the same inputs.
- Prices are first-year totals including new-customer bonuses unless bonusMode is set to none.
- The comparison shows a slice of the market; the response says how many offers exist and how to see more.
- Bookings are fulfilled by the operator; the user receives a confirmation email and, later, the provider's contract documents.
