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 ChatGPT
ChatGPT does not read a local config file. A custom MCP server is added in the product, and only after developer mode is on. These steps were checked against OpenAI's plugin connect guide and the ChatGPT MCP guide on 2026-10-01. Developer mode can be hidden by a workspace policy, so a Team or Enterprise admin may have to allow it first.
- Open ChatGPT settings, then Security and login, and turn on Developer mode.
- Open ChatGPT plugins and select the plus button.
- Enter a name such as "Travel Check" and a one-line description of what you want it to answer.
- Under Connection, choose the public endpoint and paste this URL. Include the
/mcppath. Do not add a tunnel id: this server is already public.https://travel.openkrill.app/mcp - Create the connection and review the tools ChatGPT lists. You should see
get_travel_advice,get_airport_status,compare_advisories. The feedback tools on the same server are optional and not required for the lookup. - Start a new conversation, add the connection from the tools menu, and ask: What is the current travel advice for Thailand?
No API key and no OAuth client id are required. The server answers without a login. Calls are limited per network and per day, and a limit comes back as a tool error rather than a partial answer. If the tool list is stale after a server change, open the connection and select Refresh, then start a new conversation.
The ChatGPT desktop app, Codex CLI and IDE extension share a different config. In the desktop app, open Settings, then MCP servers, choose Add server, select Streamable HTTP, and paste the same URL. In ~/.codex/config.toml the equivalent is a table named mcp_servers.travel with url = "https://travel.openkrill.app/mcp". ChatGPT on the web does not read that file. A published directory listing is also a different path: this page is the developer-mode connection, not a claim that Travel Check is already in the ChatGPT directory.
Treat the server as untrusted until you have read a few answers. A remote MCP server sees the arguments the model sends. Travel Check is read-only and documents what it sends onward on the privacy page.
If it does not work
The tool does not show up
Check that the endpoint ends in /mcp. Open the connection, select Refresh, then start a new conversation and add the connection from the tools menu. A conversation started before the connection was added does not see its tools.
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.
Developer mode is missing in ChatGPT
Developer mode is in ChatGPT settings, then Security and login, on the web. In a Team or Enterprise workspace an admin can hide it, so ask the admin to allow custom connections first. Without developer mode ChatGPT cannot add a custom MCP server.
A call checked on 2026-10-17
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 2026-10-17.
{
"method": "tools/call",
"params": {

}- 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

- 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.
