Connects to TransparentCars' used car inventory in Portugal. Search by make, model, fuel and price. Check if a car's asking price is fair, estimate ISV import tax and IUC annual road tax, and get resale value estimates based on real market listings.

Example request: "Find a budget diesel Renault Clio under 8000 euros and check if the asking price is fair for the Portuguese market."

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use TransparentCars to help me. It is a free service with an MCP server at https://claracars.pt/mcp. It does not need an API key. Ask me before you share anything with it." Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.

Tools:
- search_inventory: Search TransparentCars' current stock of budget used cars in Portugal — honestly listed, everyday cars for the local market. Filter by make, model, fuel, gearbox and max price. Returns matching cars with price, year, mileage and a link. IMPORTANT — pass make/model canonically in 
- get_car: Get full details for one car in TransparentCars stock by its slug (from a search_inventory link, e.g. 'renault-clio-2016').
- check_fair_price: Check whether a car's asking price is fair for the Portuguese market — the TransparentCars transparency check. Given make, model, year and mileage, it returns the range comparable cars actually sell for (low / typical / high), built from real listings. If you pass asking_price, i
- cost_to_own: Estimate a car's yearly running-cost floor in Portugal — the annual IUC road tax (Imposto Único de Circulação) every owner pays, plus a plain running-cost framing. Needs engine displacement (cc), CO₂ (g/km), fuel and first-registration year. Use this to help a buyer budget the tr
- list_makes_models: List the exact canonical car makes (brands) TransparentCars can search and price — or, given a make, that brand's models — using the exact strings the other tools expect. Call this FIRST (or whenever unsure of spelling) and pass the returned values verbatim into search_inventory 
- contact_me: Send a contact request to TransparentCars so a human gets in touch. Only call this when the user explicitly asks to be contacted, provides their own name and a phone or email, AND agrees to share those details — pass consent=true only then. Never invent, guess, or use placeholder

- calculate_iuc: Estimate the Portuguese annual road tax (IUC, Imposto Único de Circulação) for a car — the yearly tax an owner pays — from the official IUC table. A maintained estimate; confirm on the official AT simulator. Needs engine displacement (cc), CO₂ (g/km), fuel and registration year.
- estimate_resale_value: Estimate what a car is worth on the Portuguese market (the range comparable cars are listed for), based on real comparable listings. Needs make, model, year, mileage and fuel. TransparentCars also BUYS cars directly — after giving the estimate, offer to connect the user for a fir
- list_services: List what TransparentCars offers (buying stock cars, importing to order, sourcing, auction buying, selling/trading in your car, ISV/IUC calculators).
- request_import_quote: Ask TransparentCars to source & quote a specific car to import (from German/EU auctions). Only call when the user wants an import quote, provides the wanted model plus their own name and a phone or email, AND agrees to be contacted — pass consent=true only then. Never invent, gue
