## 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 2026-11-05.

- **Endpoint Security**: 46/100
  - 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 4 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 enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement.
  - 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**: 54/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 1313 tokens (~328/item across 4 items; 4 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 10/100
  - Stability observed for 3 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.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 4 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-11-05 (score 58, +1)

No change was recorded against any check on this day. Stability & Change Management went from 7 to 10. That category is still filling its 30-day observation window: 2 days of observed history at the previous scan, 3 at this one. The score rises as the window fills, whether or not the server changes.

## MCP tools (4)

### `rainbow_search_charters` (~300 tokens)

Rainbow charter destinations

Charter flight destinations sold by Rainbow Tours (biletyczarterowe.r.pl) matching optional destination/origin/date filters: per destination you get the country, region, nearest departure date, baggage allowance and the lowest per-person price. Prices are charter seat prices in PLN. Use rainbow_search_outbound for day-by-day flights to one destination. Result shape: { source, fetchedAt, query, search_url, count, flights: [...], price_range: { min, max } } — the list key is `flights`, but each entry is a DESTINATION, not a single flight: { destination, destination_iata, country, region, departure_date, price_per_person, currency, baggage_kg }.

Input parameters:

- `adults` (integer): Number of adults. Default 2.
- `departure_from` (string): Earliest departure date, YYYY-MM-DD.
- `departure_to` (string): Latest departure date, YYYY-MM-DD.
- `destinations` (array): Destination IATA codes to filter by, e.g. ['AYT','HRG']. Omit for all.
- `no_cache` (boolean): Force a fresh fetch and bypass this server's result cache. Default false.
- `one_way` (boolean): Search one-way charters instead of returns. Default false.
- `origins` (array): Polish origin IATA codes to filter by, e.g. ['WAW','KTW']. Omit for all.

Output parameters:

Prices are charter seat prices in PLN. Get destination codes from rainbow_search_charters. Result shape: { source, fetchedAt, query, search_url, destination, period, days_with_flights, days: [...] } — the list key is `days`, one entry per calendar day: { date, cheapest_price, flights: [{ origin, destination, departure_time, price_per_person, total_price, currency, airline_code, flight_number, cabin_baggage_kg, checked_baggage_kg, meals_included }] }. A day with no flights is simply absent.

- `adults` (integer): Number of adults. Default 2.
- `date_from` (string, required): Window start, YYYY-MM-DD.
- `date_to` (string, required): Window end, YYYY-MM-DD.

Prices are charter seat prices in PLN. Only supports Itaka's fixed airport list — the error message lists valid codes when one is unsupported. Result shape: { source, fetchedAt, query, search_url, route, total_pages, current_page, total_rates, count, itineraries: [...] } — the list key is `itineraries`. Each: { trip_type, price_total, price_per_person, currency, booking_url, outbound, return_flight }, where outbound/return_flight are { departure: { city, airport_code, date, time, carrier, flight_number }, arrival: { city, airport_code, date, time }, duration_minutes, stops } and `return_flight` is null on a one-way.

Input parameters:

- `adults` (integer): Number of adults. Default 2.

Result shape: { source, fetchedAt, query, search_url, passengers, duration, count, destinations: [...] } — the list key is `destinations`. Each: { destination_name, airport_code, country, per_person_price, total_price, currency }. There are no per-flight times here; TUI only publishes a destination price.

Input parameters:

- `adults` (integer): Number of adults. Default 2.
