## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-09-23.

- **Endpoint Security**: 57/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 11 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 64/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 2822 tokens (~256/item across 11 items; 11 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 90/100
  - Stability observed for 27 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 75/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - 0 of 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "contact_me" implies "send" and declares no destructiveHint at all, which the MCP spec reads as destructive by default.
  - An AI judge read all 11 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (11)

### `search_inventory` (~309 tokens)

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.

Input parameters:

- `fuel` (string): Fuel: petrol, diesel, hybrid, phev, electric, lpg
- `gearbox` (string): Gearbox: manual or automatic
- `limit` (integer): Max results (default 20)
- `make` (string): Full brand name in Latin, as the market lists it — 'Renault', 'Volkswagen' (not 'VW'), 'Peugeot', 'Seat'.
- `max_price` (number): Maximum price in EUR
- `min_year` (number): Earliest registration year
- `model` (string): Short model name WITHOUT engine or trim — 'Clio' (not 'Clio 1.5 dCi'), 'Golf' (not 'Golf TSI').

### `get_car` (~55 tokens)

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

Input parameters:

- `slug` (string, required): Car slug from a search_inventory result URL

### `check_fair_price` (~345 tokens)

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.

Input parameters:

- `asking_price` (number): The price being asked for THIS car, in EUR — pass it to get a fair / above-market / below-market verdict.
- `fuel` (string): Fuel: petrol, diesel, hybrid, electric
- `gearbox` (string): Gearbox: manual or automatic
- `hp` (integer): Power in hp (sharpens the comparison)
- `km` (integer, required): Mileage in km
- `make` (string, required): Full brand name in Latin — 'Renault', 'Volkswagen' (not 'VW'), 'Peugeot', 'Seat'.
- `model` (string, required): Short model name WITHOUT engine or trim — 'Clio' (not 'Clio 1.5 dCi'), 'Golf' (not 'Golf TSI').
- `year` (integer, required): Registration year

### `cost_to_own` (~198 tokens)

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.

Input parameters:

- `cc` (integer, required): Engine displacement in cm³, e.g. 1200
- `co2` (number, required): CO₂ emissions in g/km, e.g. 120
- `fuel` (string, required): Fuel: petrol, diesel, hybrid, phev, electric, lpg
- `month` (integer): First-registration month (1-12), refines the CO₂ regime
- `used` (boolean): Used vehicle (true, default)
- `year` (integer, required): First registration year, e.g. 2016

### `list_makes_models` (~117 tokens)

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.

Input parameters:

- `make` (string): Brand to list models for, e.g. 'Renault'. Omit to get the list of brands.

### `contact_me` (~200 tokens)

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.

Input parameters:

- `consent` (boolean, required): Set true ONLY if the user explicitly agreed to share their contact details and be contacted
- `contact` (string, required): A phone number or email where they can be reached
- `message` (string): What they want / their question
- `name` (string, required): The person's name (as they gave it)

### `calculate_isv` (~590 tokens)

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.

Input parameters:

- `axles` (integer): Heavy rigid goods ≥12t: axles (2/3/4).
- `cc` (integer): Engine displacement in cm³, e.g. 1950 (not needed for heavy goods/buses)
- `co2` (number): CO₂ emissions in g/km (WLTP), e.g. 130 (passenger/motorhome only)
- `config` (string): Heavy goods ≥12t: rigido or articulado (tractor+trailer).
- `from_eu` (boolean): Registered in an EU member state (true, default). Set FALSE for non-EU imports (Switzerland, UK, USA, Japan…) — non-EU used cars get NO age reduction, so the ISV is the FULL amount (plus customs duty…
- `fuel` (string): Fuel: petrol, diesel, hybrid, hybrid_diesel (diesel MHEV/HEV), phev, electric (irrelevant for heavy goods/buses)
- `peso_bruto` (integer): Gross weight (kg). REQUIRED for goods vehicles (van_10/commercial_*/pesados_mercadorias): their IUC is weight-based (Cat C/D).
- `regiao_autonoma` (boolean): Used exclusively in Açores/Madeira → −50% IUC (Cat C/D).
- `suspension` (string): Heavy goods ≥12t: driven-axle suspension.
- `tractor_axles` (integer): Articulated ≥12t: tractor axles (2/3).
- `trailer_axles` (integer): Articulated ≥12t: trailer axles (1/2/3).
- `used` (boolean): Used vehicle (true, default) or new (false)
- `utilizacao` (string): Goods use: particular (Cat C, default) or publico/rental (Cat D).
- `vehicle_type` (string): Category (default passenger). Goods van → van_10/commercial_*; heavy goods >3500kg → pesados_mercadorias; bus → pesados_passageiros; motorhome → autocaravana; motorcycle → motorcycle.
- `year` (integer, required): First registration year, e.g. 2016

### `calculate_iuc` (~444 tokens)

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.

Input parameters:

- `year` (integer, required): First registration year, e.g. 2016

### `estimate_resale_value` (~302 tokens)

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.

Input parameters:

### `list_services` (~41 tokens)

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

### `request_import_quote` (~221 tokens)

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. Submitting shares the provided contact details per the TransparentCars privacy policy.

Input parameters:

- `budget` (number): Budget in EUR
- `consent` (boolean, required): Set true ONLY if the user explicitly agreed to share their contact details and be contacted
- `contact` (string, required): A phone number or email where they can be reached
