## 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 2026-08-03.

- **Endpoint Security**: 80/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - 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**: 62/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 1263 tokens (~252/item across 5 items; 5 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 27/100
  - Stability observed for 8 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.
- **Capabilities**: 40/100
  - Spec-recency check failed: implements MCP spec 2025-03-26; the latest is 2026-07-28.

## MCP tools (5)

### `search_vehicles` (~456 tokens)

Search Cars

Search available cars on FINN with filters. Returns matching vehicles with prices, images, and links. All filter values use German names (e.g. "Elektro" not "Electric", "Schwarz" not "Black"). IMPORTANT: Always show detail_url as a clickable link for each vehicle. The vehicle_id field is an internal API identifier for get_vehicle_details — never display it to users.

Input parameters:

- `available_from` (string): Earliest delivery date (YYYY-MM-DD)
- `available_to` (string): Latest delivery date (YYYY-MM-DD)
- `brands` (array): Car brands (e.g. ["BMW", "Audi", "Mercedes-Benz"])
- `cartypes` (array): Car types in German (e.g. ["SUV", "Kombi", "Kleinwagen", "Van"])
- `colors` (array): Colors in German (e.g. ["Schwarz", "Weiß", "Blau"])
- `fuels` (array): Fuel types in German (e.g. ["Elektro", "Benzin", "Diesel", "Plug-In-Hybrid"])
- `has_deals` (boolean): Filter for cars with special deals/discounts
- `has_hitch` (boolean): Filter for cars with hitch
- `is_young_driver` (boolean): Filter for cars allowing drivers under 23
- `limit` (number): Number of results (1-10, default 5)
- `max_ev_range` (number): Maximum electric range in km
- `max_power` (number): Maximum power in kW
- `max_price` (number): Maximum monthly price in EUR
- `min_ev_range` (number): Minimum electric range in km
- `min_power` (number): Minimum power in kW
- `min_price` (number): Minimum monthly price in EUR
- `models` (array): Car models (e.g. ["iX1", "3er Limousine"])
- `sort` (string): Sort order: asc/desc by price, availability, or last_added
- `terms` (array): Subscription term lengths in months (available: 1, 6, 12, 18, 24, 36)

### `get_vehicle_details` (~160 tokens)

Vehicle Details

Get full specifications, equipment, all images, and pricing per term for a specific vehicle. Use a vehicle_id from search_vehicles results. IMPORTANT: Always show `detail_url` as a clickable link — it points to the FINN configurator where the user picks term and km. To produce a direct checkout link for a specific term + km combination (and optionally a one-time Fahrzeugbereitstellung), call `get_subscription_pricing` and use the `checkout_url` it returns. Never construct checkout URLs yourself. The `vehicle_id` field is an internal API identifier — never display it to users.

Input parameters:

- `vehicle_id` (string, required): The vehicle product ID (e.g. "bmw-ix1-12345-alpinweissuni")

### `get_available_filters` (~72 tokens)

Available Filters

Discover what's currently available in FINN's fleet. Returns all brands (with nested models), car types, fuel types, colors, subscription terms, gearshifts, and price/power/range bounds. Use this to answer questions like 'What brands does FINN offer?' or to validate filter values before searching.

### `get_subscription_pricing` (~377 tokens)

Subscription Pricing

Calculate exact monthly subscription price for a specific vehicle, term, and mileage combination. Returns base price, km add-on, total, and a canonical checkout URL.

Checkout URL structure (always use the URL returned in `checkout_url` verbatim — do NOT construct your own):
  https://www.finn.com/de-DE/checkout/cart/{vehicleId}/{term}/{kmPackage}
  https://www.finn.com/de-DE/checkout/cart/{vehicleId}/{term}/{kmPackage}?downPaymentAmount={amount}

The three positional path segments after `/cart` are vehicle id, term in months, and monthly km package — in that order.

About `down_payment_amount` (Fahrzeugbereitstellung):
\- Fahrzeugbereitstellung is a one-time vehicle provisioning fee.
\- When `down_payment_amount` is provided, it is paid upfront as Einmalzahlung (one-time payment) and the URL includes `?downPaymentAmount={amount}`.
\- When omitted, the same fee is spread across the term and absorbed into the monthly price; the URL has no query string.

Input parameters:

- `down_payment_amount` (number): Optional one-time Fahrzeugbereitstellung (vehicle provisioning fee) in EUR, paid upfront as Einmalzahlung. When provided, the checkout URL gets `?downPaymentAmount={amount}` and the monthly price dro…
- `km_package` (required): Monthly km package (500, 1000, 1500, 2000, 2500, 3000, 4000, 5000)
- `term_months` (required): Subscription term in months (1, 6, 9, 12, 13, 18, 24, 36)
- `vehicle_id` (string, required): The vehicle product ID

### `get_internal_link_url` (~198 tokens)

Internal Link URLs

Get canonical FINN URLs for a brand and its models — for building internal linking blocks on SEO pages. For each model returns three URLs that target DIFFERENT funnels: `mdp_url` (marketing/brand page), `plp_subscribe_url` (subscription product listing, /de-DE/subscribe/{brand}_{model}), and `plp_leasing_url` (leasing product listing, /de-DE/leasing/{brand}_{model}). Use `plp_leasing_url` when linking from a Leasing advisory, `plp_subscribe_url` when linking from subscription content. If `model` is omitted, returns all currently available models for the brand.

Input parameters:

- `brand` (string, required): Brand name (e.g. "Ford", "Mercedes-Benz", "BMW")
- `model` (string): Optional model name (e.g. "Puma", "iX1"). If omitted, returns all available models for the brand.
