## 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**: 74/100
  - 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.
  - 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**: 65/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 353 tokens (~353/item across 1 items; 1 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.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (1)

### `search` (~353 tokens)

Searches live rental-car offers for a pickup location and rental period, optionally with a different dropoff location, pickup/dropoff times, driver age, currency, and language. Use this when the user wants to compare available rental cars, prices, vendors, categories, or booking links for a specific trip. Do not use it for flights, hotels, public transport, or general travel planning unless the user has car-rental intent. The tool queries external provider APIs in real time, returns price-ranked results grouped by SIPP/category, and may include affiliate booking links. It does not book cars, modify reservations, charge users, or store user data.

Input parameters:

- `age` (integer): Driver age. Defaults to 30. Younger drivers may incur surcharges.
- `currency` (string): Preferred ISO 4217 currency code for prices, such as EUR, USD, or GBP. Defaults to EUR.
- `dropoff_date` (string, required): Dropoff date. Must be after the pickup date.
- `dropoff_location`: Optional different dropoff location. If omitted, the pickup location is used.
- `dropoff_time` (string): Dropoff time in 24-hour HH:MM format. Defaults to 12:00.
- `language` (string): Preferred response language code, such as en or de. Defaults to en.
- `location` (string, required): Pickup location, such as a city, airport, station, address, or landmark.
- `pickup_date` (string, required): Pickup date. Accepts common date formats such as YYYY-MM-DD, DD.MM.YYYY, or natural-language dates.
- `pickup_time` (string): Pickup time in 24-hour HH:MM format. Defaults to 12:00.

Output parameters:

- `result` (string)
