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. How we score → Why this is hard to score →
Endpoint Security80
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability67
- AI-judged instruction clarity (excellent).Pass
- 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. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 5 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities40
- Spec-recency check failed: implements MCP spec 2025-03-26; the latest is 2026-07-28. See how to fix → Fail
How do I install the FINN Auto - Car Subscription MCP server?
FINN Auto - Car Subscription is a hosted endpoint at https://www.finn.com/api/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

No change was recorded against any check on this day. Stability & Change Management went from 93 to 97. That category is still filling its 30-day observation window: 28 days of observed history at the previous scan, 29 at this one. The score rises as the window fills, whether or not the server changes.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
get_available_filters Available Filters ~72
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.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
get_internal_link_url Internal Link URLs ~198
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.
| Name | Type | Req | Description |
|---|---|---|---|
| brand | string | yes | 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. |
No output schema declared.
No examples provided.
get_subscription_pricing Subscription Pricing ~377
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.
| Name | Type | Req | Description |
|---|---|---|---|
| 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 | – | yes | Monthly km package (500, 1000, 1500, 2000, 2500, 3000, 4000, 5000) |
| term_months | – | yes | Subscription term in months (1, 6, 9, 12, 13, 18, 24, 36) |
| vehicle_id | string | yes | The vehicle product ID |
No output schema declared.
No examples provided.
get_vehicle_details Vehicle Details ~160
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.
| Name | Type | Req | Description |
|---|---|---|---|
| vehicle_id | string | yes | The vehicle product ID (e.g. "bmw-ix1-12345-alpinweissuni") |
No output schema declared.
No examples provided.
search_vehicles Search Cars ~456
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.
| Name | Type | Req | Description |
|---|---|---|---|
| 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"]) |

| 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 |
