Connect TravelDay to your AI assistant

Ask your own assistant where you have been, how many Schengen days you have left, or what is on your next trip. TravelDay speaks the Model Context Protocol, so any MCP client can connect.

The only thing you need

https://travelday.world/api/mcp

Paste that into your assistant. It will send you here to sign in and approve the connection. TravelDay never asks another app for your password, and you can end the connection at any time from Settings → Connected apps.

Step by step

Grok

Works on the free tier. Business and Enterprise accounts need an admin to add it first.

  1. 1Go to grok.com/connectors.
  2. 2Choose New Connector, then Custom.
  3. 3Paste the server URL above and save. Grok will hand you to TravelDay to sign in and approve.
  4. 4Come back to Grok and ask it something. It finds the tools on its own once connected.

Claude

One connection covers claude.ai, Claude Desktop, Claude mobile, Claude Code and Cowork — they share the same account.

  1. 1Open Settings → Connectors and choose to add a custom connector.
  2. 2Paste the server URL above.
  3. 3Sign in to TravelDay when prompted and approve the permissions you want to grant.

ChatGPT

Needs a paid plan (Plus, Pro, Business, Enterprise or Edu) and a browser. Free and Go accounts cannot add a custom server at all.

  1. 1On chatgpt.com, open Settings → Security and login and turn on Developer mode. On Business, Enterprise and Edu the toggle only appears after an admin allows it.
  2. 2Go to chatgpt.com/plugins and press the + button.
  3. 3Name it TravelDay, add a one-line description, and paste the server URL above as the MCP server URL. Leave authentication on OAuth with no credentials to paste.
  4. 4Press Create. ChatGPT sends you to TravelDay to sign in and approve, then scans the server and shows you the tools it found.
  5. 5Open a new chat, choose Developer mode from the + menu next to the message box, and tick TravelDay. Name it in the prompt if ChatGPT reaches for a web search instead: “Use TravelDay to tell me how many Schengen days I have left.”

A ChatGPT connection is read only. It answers from your history and cannot add, correct or delete anything. Use Claude or Grok if you want your assistant to write. Setup is web only, and the app appears under Drafts until you use it.

OpenClaw

Command line. Run these in a terminal.

openclaw mcp add travelday \
  --url https://travelday.world/api/mcp \
  --transport streamable-http \
  --auth oauth

openclaw mcp login travelday

The login step opens a browser to sign in. Check it worked with openclaw mcp doctor travelday --probe.

Anything else

Hermes, Codex, Cursor and other MCP clients all take a server URL somewhere in their settings.

Look for MCP servers, Connectors or Integrations, add a remote or custom server, and paste the URL above. If the client asks for a transport, choose HTTP or streamable HTTP. If it asks for an API key, it is looking at the wrong kind of server — TravelDay uses a sign-in flow instead, and there is no key to paste.

What it can and cannot do

You choose how much access to grant when you approve the connection:

  • Read — your travel history, day limits, trips, saved places and documents list. Most people only ever need this one.
  • Write — add or correct a trip or a visit.
  • Delete — remove them.

Anything that changes or removes data has to be confirmed in the moment, every time. Your assistant cannot delete a year of history because it misread a sentence. Connections also count against the same daily limit as the assistant inside TravelDay, and connecting an outside app is not a way around it.

Every connection is listed under Settings → Connected apps with what it can do and when it last used the connection, and one button ends it.

If it will not connect

  • Check the URL ends in /api/mcp with no trailing slash.
  • The assistant needs to reach the public internet. A work laptop behind a restrictive proxy may not.
  • If sign-in succeeds but no tools appear, disconnect and reconnect — some clients only look for tools once, at the moment you add the server.
  • Still stuck? Email support@travelday.world and say which assistant you are using.

Setup paths change as these products ship. If a menu here does not match what you see, the client's own documentation is the authority — the server URL above is the part that does not change.

Connected? Try a real question.

Ask your assistant “How many Schengen days do I have left?” to confirm it can read your TravelDay data.
