MCP server for the Transport for London (TfL) Unified API — lines, journeys, stop points, arrivals, bike points, and more over stdio
MCP server for the Transport for London (TfL) Unified API — lines, journeys, stop points, arrivals, bike points, and more over stdio. That is what the tfl mcp mcp server brings to an AI assistant: the same capability, reachable through the Model Context Protocol rather than a separate app or dashboard.
Setup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client. The configuration blocks on this page cover the common clients.
The server publishes 14 tools. What each one is for:
Domain — ToolsAccidentStats — accident_statsAirQuality — air_qualityBikePoint — bike_points_all, bike_point_search, bike_point_by_idCabwise — cabwise_searchJourney — journey_plan, journey_modesLine — 14 toolsMode — mode_active_service_types, mode_arrivalsOccupancy — 5 toolsPlace — 7 toolsRoad — 8 toolsSearch — 5 toolsConfiguration is passed through the environment: TFL_API_KEY. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
Plenty of developer tooling servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Tfl MCP's toolset — Domain, AccidentStats, AirQuality and 11 more — is a fair guide to whether it matches your workflow. It is maintained by daanrongen; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
