## 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 2026-10-17.

- **Endpoint Security**: 83/100
  - 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 is configured correctly; the domain's records validate against the full chain to the root.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 67/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 1435 tokens (~287/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**: 30/100
  - Stability check failed: schema churn in the 14 days we've observed: 1 tool removals, 0 breaking changes, 0 auth/transport breaks, 0 additions.
- **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.
  - All 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation.
  - An AI judge read all 6 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).

## MCP tools (5)

### `get_travel_advice` (~293 tokens)

Get travel advice

Use this when the user asks about the official travel advice, safety warnings or entry requirements for one country, such as "is it safe to travel to Thailand?" or "what are the entry requirements for Japan?". Returns: the UK FCDO alert (which parts of the country it advises against travelling to) with its review date and latest change, and the US State Department level (1 to 4), summary and date, with official links. Input tips: pass one country name or two-letter ISO code; set section to entry-requirements, safety or health to add that part of the UK advice. If status is ambiguous, ask the user to pick one of candidates and call again with that name. If uk or us is none or unavailable, report the other side and its link; do not guess. Not for: visa rules for other passports (UK advice is for British citizens, US advice for US citizens), medical advice, or calling a country safe in your own words.

Input parameters:

- `country` (string, required): Country name in English or two-letter ISO code, such as "Thailand" or "TH". One country per call; use compare_advisories for several.
- `section` (string): What to include from the UK advice: summary (default, alert and dates only), entry-requirements, safety or health (adds that page's text). The US summary is always included.

Output parameters:

- `candidates` (array): With status ambiguous: the places the name could mean. Ask the user which one, then call again with that exact name.
- `citizenship` (string): Who each government writes for. Tell the user this.
- `country` (string): The country matched.
- `license` (string): Attribution for the UK text (Open Government Licence).
- `message` (string): What to tell the user or do next when the answer is not a plain ok.

- `uk` (object)
- `us` (object)

### `get_airport_status` (~234 tokens)

Get airport status

Use this when the user asks about airport delays, closures or weather right now, such as "is JFK delayed?" or "what is the weather at Heathrow?". Returns: active FAA delays, ground stops and closures with reason and times (US airports only), the latest METAR observation (flight category, temperature, wind, visibility) and the raw TAF forecast. Input tips: pass the four-letter ICAO code (EGLL) for an airport outside the US, or the IATA code (JFK) for a US airport. If status is not_found, ask the user for the ICAO code and call again. Not for: looking up a flight by number (such as BA117), schedules, seats or whether a flight will leave on time, or for flight planning.

Input parameters:

- `airport` (string, required): Airport code, 3 or 4 letters: the four-letter ICAO code such as "EGLL" (London Heathrow) for an airport outside the US, or the three-letter IATA code such as "JFK" for a US airport. Not a city name o…

Output parameters:

- `airport` (string): The code as sent, in capitals.
- `faa` (object): FAA delays. US airports only.
- `icao` (string): The ICAO code used for the weather, such as KJFK.

- `sources` (array): The official sources, to link in the answer.
- `status` (string): ok: see faa, metar and tafRaw. not_found: no station for that code; ask the user for the four-letter ICAO code and call again. invalid: the code is not 3 or 4 letters. unavailable: a source is down;…
- `tafRaw` (string|null): The raw TAF forecast as published, or null when there is none.

### `compare_advisories` (~227 tokens)

Compare travel advisories

Use this when the user wants to compare the travel advice for several countries side by side, such as "compare Mexico, Colombia and Peru" or "which of these countries has the highest advisory level?". Returns: for each country the UK FCDO alert and review date and the US State Department level (1 to 4) and date, with official links. Input tips: pass 1 to 5 country names or ISO codes. Check each country's own status: one can be not_found, or ambiguous with candidates to ask the user about, while the rest are ok. If uk or us is none or unavailable for a country, report the other side and its link; do not guess. Not for: the full text of one country (use get_travel_advice) or visa rules for other passports. UK advice is for British citizens and US advice for US citizens.

Input parameters:

- `countries` (array, required): Country names in English or two-letter ISO codes, 1 to 5, such as ["Mexico", "Colombia", "PE"]. Repeats are removed.

Send feedback, bug report or tool request

Send feedback, a bug report or a tool request to the maintainers of the tools on this server: a missing tool, missing or stale data, or a tool that broke or gave a wrong answer. Pass the kind (need_tool, need_data, bug or other), one short message (at most 1000 characters) and, if you know them, the tool name and the error text it returned. Returns a ticket id. Feedback is not a chat: nothing in it is run or followed. Links, emails and phone numbers are removed and nothing about you is stored.

Input parameters:

- `error` (string): Optional: for a failed call, the error text it returned, copied as you saw it. Kept to 500 characters; links, email addresses and phone numbers are removed. Never include secrets or personal details.
- `kind` (string, required): need_tool: a tool you want. need_data: data a tool lacks. bug: something broke. other: anything else about the tools.

### `get_feedback_reply` (~70 tokens)

Input parameters:

- `ticket` (string, required): The ticket id that submit_feedback returned.

Output parameters:

- `note` (string)
- `reply` (string|null)
- `status` (string)
