Triplyfy MCP is a remote MCP server that integrates Claude with the Triplyfy trip-planning app, enabling the LLM to plan, edit, and save itineraries. Triplyfy is a simple app for creating and sharing itineraries, with a view public by link and editing restricted to Google sign-in. Users can drag and drop places and notes across days, view everything on a map, and add flights. The MCP setup uses Google OAuth on first connection, after which Claude exchanges a code for a Triplyfy session token valid for roughly 30 days. This token authenticates only Claude’s requests to Triplyfy; the server performs only the actions requested—creating, reading, updating trips and searching flights. The setup requires no manual gateway run; it is configured in Claude Desktop under Settings > Developer > MCP Servers by adding the Triplyfy MCP SSE endpoint. The system emphasizes secure, token-based access and supports trip management, itinerary item manipulation, flight searches, and map-based visualization.
