Multimodal Journey Plan
Use when / do not use when
Section titled “Use when / do not use when”Use this workflow for a door-to-door public transport, walking, cycling, or mixed-mode journey with route alternatives, transfers, and a shareable TripGo plan. Do not use it for emergency travel, guaranteed accessibility, or ticket purchase.
Inputs to resolve
Section titled “Inputs to resolve”Collect specific origin and destination descriptions, departure or arrival time with timezone, acceptable modes, walking tolerance, accessibility needs, party size, and preference for speed, cost, or fewer transfers.
Tool workflow
Section titled “Tool workflow”The upstream names below are capability labels. Select the currently advertised MCP tool whose description identifies that upstream capability.
- Use Maps
search_placesto disambiguate human place descriptions and obtain coordinates before routing. - Use
tripgo-locationsaround those coordinates only when nearby transport-related locations or stops help resolve the journey. - Call
tripgo-routingwith the resolved coordinates, explicit time constraint, accessibility flag when requested, and allowed modes. Compare a small number of materially different alternatives. - When a route identifies a stop and near-term departure matters, use
tripgo-departuresfor that stop. - Use
tripgo-get-trip-urlfor the selected route and return the shareable link.
Validation and fallback rules
Section titled “Validation and fallback rules”Keep origin, destination, and timezone consistent across calls. Distinguish scheduled routing from live departure observations. Do not promise step-free access, fares, seat availability, or on-time operation unless the returned data supports it. If Maps and TripGo resolve different places, stop and ask the user to choose.
Output contract
Section titled “Output contract”Lead with the recommended route, then show one or two useful alternatives with door-to-door duration, modes, transfers, walking, key departure times, and trade-offs. Include the TripGo link and state when live data should be checked again.
Safety and side effects
Section titled “Safety and side effects”This workflow is read-only. It does not buy tickets or reserve travel. Minimize the use of private home addresses in the response.
