Questions it answers

Check what the UK and US governments currently advise about a country, and see live delays and weather at an airport.

Ask "what is the travel advice for Thailand?", "what are the entry requirements for Japan?", "compare Mexico, Colombia and Peru" or "is JFK delayed right now?".

Travel Check reads the UK Foreign, Commonwealth and Development Office (FCDO) travel advice on GOV.UK, the US State Department travel advisories, the FAA National Airspace System status and the NOAA Aviation Weather Center.

Every answer shows the advisory level or alert, the date it was last reviewed, and a link to the official page.

UK advice is written for British citizens and US advice for US citizens, and the answer says so: entry rules and risks differ by passport, so check your own government's advice. It does not include visa rules for other nationalities.

It is not medical, legal or safety advice and not for flight planning. Advisories change, so confirm on the official page before you travel. FAA delay data covers US airports only.

UK content is published under the Open Government Licence v3.0, © Crown copyright. It stores nothing about you: answers are cached for a few hours, and the only lasting record is a daily count of calls per tool.

Tools

get_travel_advice, 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.
get_airport_status, 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.
compare_advisories, 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.

Add Travel Check in Claude

Claude connects to a remote MCP server as a custom connector. The connection is made from Anthropic's cloud, not from your laptop, so the server must be on the public internet. Travel Check is. These steps were checked against Claude's custom-connector article (updated 2026-08-11) and the Claude Code MCP docs on 2026-10-01.

On a Pro or Max plan:

Open Customize, then Connectors.
Select the plus button, then Add custom connector.
Paste https://travel.openkrill.app/mcp. Leave Advanced settings empty: this server does not need an OAuth client id or secret.
Select Add. The connector is yours. Anthropic has not reviewed it, and it is not a Directory listing.
In a conversation, open the plus button, then Connectors, and enable Travel Check. Ask: What is the current travel advice for Thailand?

On Team and Enterprise, an Owner adds the connector first at Organization settings, then Connectors, then Add, then Custom, then Web, and pastes the same URL. Members then connect it from Customize. A Free plan can add one custom connector.

In Claude Code, add it from the project directory:

claude mcp add --transport http travel https://travel.openkrill.app/mcp

That writes a local or user config. A JSON entry needs "type": "http" (or streamable-http) plus the url. An entry with a url and no type is skipped. Confirm with claude mcp get travel. The tools you should see are get_travel_advice, get_airport_status, compare_advisories.

If Claude tries to fetch https://travel.openkrill.app/mcp from its code sandbox and reports HTTP 403, the block is Claude's sandbox network allowlist, not this server. The sandbox proxy answers 403 with x-deny-reason: host_not_allowed for every host outside the allowlist. Use the connector above instead: connector calls come from Anthropic's cloud and do not pass the sandbox proxy. To let the sandbox reach it as well, an Owner adds travel.openkrill.app under Settings, then Capabilities, then Additional allowed domains.

Enable the connector only in conversations that need it. Claude can call the tools while you work, including during research, so turn off any tool you do not want invoked. Travel Check does not write to your accounts. It still receives the arguments of each call. Read the privacy page before you paste anything that is not public.

If it does not work

The tool does not show up

In Claude, enable the connector in the conversation from the plus button, then Connectors. In Claude Code, run claude mcp list from the same directory you added it in, then start a new session: a running session does not load a new server.

429 or rate_limited

Each server takes 60 calls a minute from one network, and some tools take fewer. Past that the call comes back as a tool error that starts with rate_limited: wait a minute and ask again. daily_limit means the server reached its shared daily cap, which resets at 00:00 UTC. A limit is not an answer, so do not read it as no results. For higher limits, ask support@openkrill.app for a key.

JSON entry has no type

Claude Code skips an entry in .mcp.json that has a url but no type. Add "type": "http" next to the url, or add the server with claude mcp add --transport http, which writes the type for you. The VS Code entry needs the same type field. Cursor and Pi read the url alone.

A call checked on 2026-10-11

Thailand is the country in the plugin's starter prompts. The answer is the published advisory, not a visa ruling. The request below was posted to https://travel.openkrill.app/mcp as tools/call. HTTP 200. Source: the Travel Check server, read 2026-10-11.

{
  "method": "tools/call",
  "params": {
    "name": "get_travel_advice",
    "arguments": {
      "country": "Thailand"
    }
  }
}

status. ok
country. Thailand
notice. Government advisory text with its date and source, for information only. It is not medical, legal or safety advice, and advisories change: confirm on the linked official page before you travel.
uk name. Thailand
uk status. ok
us name. Thailand

Repeat the call yourself if you need a newer reading. Cached answers expire. A rate limit is not a result: wait and try again. Nothing in the call is a ranking, a filing, or advice.

Using it in production

Nothing to install and nothing to run: no package, no Python or Node.js version and no environment variable. Travel Check runs on our servers, and your client only needs the URL https://travel.openkrill.app/mcp.

Rate limit	60 tool calls a minute from one network. `initialize` and `tools/list` do not count.
Daily cap	5000 tool calls a day per server, shared by every caller. It resets at 00:00 UTC.
At a limit	The call comes back as a tool error that starts with `rate_limited` (wait a minute) or `daily_limit` (try after 00:00 UTC), never as a partial answer.
Key	None. Do not add an `Authorization` header or a key field.
Higher limits	Email support@openkrill.app with the server name, the calls a day you expect and what they are for. We answer within 1 business day.
Freshness	Some answers come from a short cache. Each guide shows the date of its checked call; repeat a call when you need a newer reading.
Uptime	Scheduled test calls check the servers through the same endpoint. There is no SLA yet.
Data	What each server receives and keeps is on the privacy page.

Frequently asked questions

How do I install the Travel Check MCP server in Claude?

In Claude, open Customize, then Connectors, choose Add custom connector and paste https://travel.openkrill.app/mcp. In Claude Code, run claude mcp add --transport http travel https://travel.openkrill.app/mcp. No restart is needed for either.

Do I need an API key to run Travel Check in Claude?

No. This server takes no API key. For higher limits, email support@openkrill.app with the server name (Travel Check), the calls a day you expect and what they are for. We answer within 1 business day.

What should I do if Travel Check does not connect in Claude?

Check that the connector URL ends in /mcp and that Advanced settings are empty. In Claude Code, run claude mcp get travel; a JSON entry with a url but no type is skipped, so add type http.
