The IMV connector for AI assistants

The IMV connector lets an AI assistant such as Claude answer questions about selling a home in Belgium with the figures of ImmoMakelaarVergelijker (IMV): the costs of selling, prices in your municipality from Statbel, how IMV works, and a link to our form for comparing agents. It works through the Model Context Protocol (MCP), is free, and needs no account or sign-in.

The four tools

  • estimate_selling_costs

    Estimates what selling a home in Belgium costs: the agent's commission incl. 21% VAT, EPC, electrical inspection, asbestos certificate (Flanders), soil certificate and the release of a mortgage, plus the registration duties the buyer pays.

    Example question: “What does it cost to sell my house in Flanders for €400,000?”

  • local_price_facts

    Official median sale prices of a Belgian municipality from Statbel open data (CC BY 4.0), with the province and region medians.

    Example question: “What is the median price of a house in Ghent?”

  • how_imv_works

    How IMV selects agents (postcode, at most 3, BIV-registered), who pays, and what happens to a seller's data.

    Example question: “How does ImmoMakelaarVergelijker choose agents, and who pays?”

  • get_comparison_form_link

    A link to IMV's form for requesting proposals from up to 3 local agents. Only the postcode and the property type are prefilled; the seller enters their own details and gives consent on IMV's page.

    Example question: “I want to compare agents for my apartment in 2018 Antwerp.”

Good to know

Free for sellers. Agents pay IMV per lead. Not a full market overview. Up to 3 BIV-registered agents per postcode.

IMV is a comparison service: agents pay IMV a flat fee per request they receive, and the seller pays nothing. Only agents who are IMV partners can be proposed, so this is not a full market overview. IMV does not rank the agents and gives no advice on the price or the sale.

What data the tools receive

  • Only what the assistant passes along with a question: for selling costs the region, the expected price, the property type and, if given, the commission, whether it was built before 2001, whether an electrical inspection is needed and the balance and rate of a mortgage; for prices a postcode or municipality and the property type; for the form link at most a postcode and the property type; and the language.
  • No tool asks for a name, mobile number, e-mail address or address. The form link carries no personal data.
  • IMV does not store these questions. Of the use, we keep only daily counts (which tool, which assistant, which result), without personal data. As for any request, our server logs record the IP address of the assistant's server.
  • The chat with the assistant itself falls under the privacy policy of Anthropic, OpenAI or your assistant's provider.

Everything about the connector and your data is in point 13 of our privacy policy. Privacy policy, point 13

Limits

  • Only for homes in Belgium.
  • Prices are medians of registered sales, not a valuation of a specific home.
  • Selling costs are estimates; where no legal tariff exists, they are market ranges.
