Used & imported cars in Portugal: search stock, ISV/IUC tax calc, resale value, contact.

VerifiedStreamable HTTPWeb executableFinanceBusiness & Commerce

Overview

AI-generated overview

Lets an assistant search used and imported cars in Portugal, estimate ISV/IUC taxes and resale value, and send contact or import-quote requests.

What you can do
  • Search and read stock: search inventory by make, model, fuel, gearbox and price, get full details for one car, list canonical makes and models
  • Estimate Portuguese taxes: ISV import tax and annual IUC road tax from engine size, CO2, fuel and year
  • Value a car: check whether an asking price is fair and estimate resale value from comparable listings
  • Budget ownership: estimate yearly running-cost floor including IUC
  • Request contact: send a contact request or an import quote to the business, and list its services
When to use it
Useful when someone is shopping for a used car in Portugal, importing a car into Portugal, or wants a quick estimate of ISV, IUC or resale value before talking to a dealer.
Requirements
Runs as a remote Streamable HTTP endpoint or locally via npx (Node.js). No API keys or accounts. Optional environment variables set the API base, response language (pt/en/ru/ua) and local HTTP port/path.
Before you install
contact_me and request_import_quote send the user's name and phone or email to Clara Carros; only call them with explicit consent. Tax and value figures are estimates, not official quotes. The server is a wrapper over a commercial dealer's public API, so results reflect that dealer's stock and listings.

Installation

In SourceWeft

  1. Open Claracarspt in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.claracarspt%2Fmcp/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Clara Carros MCP server

[MCP] [License: MIT]

An MCP server that lets AI assistants work with Clara Carros — used & imported cars in Portugal. Search live stock, estimate the Portuguese import tax (ISV), estimate a car's resale value, and get in touch.

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

Cline / one-click install: see llms-install.md — the machine-readable setup guide.

Notes

  • Estimates, not quotes. ISV and resale figures are estimates; the official ISV is assessed by the Portuguese tax authority.
  • Privacy. contact_me / request_import_quote send the details the user provides to Clara Carros (privacy policy); they're rate-limited and require explicit user intent.
  • No business logic or data lives in this repo — it only calls the public API.

Related

  • Calculators: the ISV/IUC tax logic this server calls is open-source at claracarspt/calcs — a zero-dependency Python library + key-free API.

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 Latin, as the Portuguese market lists them: make = full brand name ('BMW', 'Mercedes-Benz' not 'Mercedes', 'Volkswagen' not 'VW'); model = the short series/model WITHOUT the engine or trim suffix ('Golf' not 'Golf 1.5 TSI', 'Clio' not 'Clio dCi'). Put the fuel in the fuel field, not the model. If unsure of the spelling, call list_makes_models first.

Parametersfuelmakelimitmodelgearboxmin_yearmax_price

get_car

Get full details for one car in TransparentCars stock by its slug (from a search_inventory link, e.g. 'renault-clio-2016').

Parametersslugrequired

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, it also gives a plain verdict: fair, above market, or below market — so a buyer knows before they walk in. Works for ANY car (a listing you found elsewhere, or one of ours). IMPORTANT — pass make/model canonically in Latin: make = full brand name ('Renault', 'Volkswagen' not 'VW'); model = short name WITHOUT engine/trim ('Clio' not 'Clio dCi', 'Golf' not 'Golf 1.5 TSI'). If unsure of spelling, call list_makes_models first.

Parametershpkmrequiredfuelmakerequiredyearrequiredmodelrequiredgearboxasking_price

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 true cost of keeping a car, beyond the sticker price.

Parametersccrequiredco2requiredfuelrequiredusedyearrequiredmonth

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 / check_fair_price. No make = the list of brands; with a make = that brand's models.

Parametersmake

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 / example / test contact details: pass ONLY the real name and real phone or e-mail the user gave you in this conversation. If you don't have a real phone or e-mail from the user, ask them for it before calling — do not submit fake values. Submitting shares the provided contact details per the TransparentCars privacy policy.

Parametersnamerequiredconsentrequiredcontactrequiredmessage

calculate_isv

Estimate Portuguese car import tax (ISV, Imposto Sobre Veículos) from the official ISV formula (engine-cc + CO₂ components, with age reduction for used cars). A maintained estimate: it matches the AT (Finanças) simulator to the cent on the common WLTP cases, but is not the official figure and may differ on edge cases (NEDC, light-commercial, month rounding) — confirm the final amount on the official AT simulator. Needs engine displacement (cc), CO₂ (g/km, WLTP), fuel and registration year.

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 firm buy-out offer (via contact_me or the /sell page). IMPORTANT — pass make/model canonically in Latin, as the Portuguese market lists them: make = full brand name ('BMW', 'Mercedes-Benz' not 'Mercedes', 'Volkswagen' not 'VW'); model = the short series/model WITHOUT the engine or trim suffix (BMW: '320','330' not '320d'; Mercedes: 'C 220','A 250' not 'C220d'; others: 'Golf','Corolla','3008'). If unsure of the spelling, call list_makes_models first.

Parameterskmrequiredfuelmakerequiredyearrequiredmodelrequired

list_services

List what TransparentCars offers (buying stock cars, importing to order, sourcing, auction buying, selling/trading in your car, ISV/IUC calculators).

Takes no parameters.

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, guess, or use placeholder / example / test contact details: pass ONLY the real name and real phone or e-mail the user gave you in this conversation. If you don't have a real phone or e-mail from the user, ask them for it before calling — do not submit fake values.
