TransparentCars MCP server

An MCP server that lets AI assistants work with TransparentCars — honest, budget used cars for the local Portuguese market. Search live stock, check whether a car's asking price is actually fair, estimate the yearly cost of keeping a car on the road, and get in touch.

It's a thin, open-source wrapper over the public transparent.pt API — no keys, no setup beyond adding the server.

Tools

Tool	What it does
search_inventory	Search current budget stock by make, model, fuel, gearbox, price, year
get_car	Full details + specs for one car
check_fair_price	The market range a car sells for — plus a fair / above-market / below-market verdict on an asking price
cost_to_own	The annual IUC road tax + a plain running-cost framing for budgeting
list_makes_models	Canonical brand/model names the other tools expect
contact_me	Ask a human to get in touch (needs the user's consent + contact)

The fair-price check is the point: paste any listing's price and get a straight answer on whether it's a good deal — no sales spin.

Notes

• Estimates, not guarantees. The fair-price range and running-cost figures are estimates built from real comparable listings and the official road-tax table; treat them as guidance, not a formal valuation.
• Privacy. contact_me sends the details the user provides to TransparentCars (privacy policy); it requires explicit user intent and consent.
• No business logic or data lives in this repo — it only calls the public API.
