Parameters

A JSON object in the request body; in an MCP client, the arguments of the tool call.

NameTypeRequiredDescription
pointsarray of string or objectYesStart, optional stops and destination, in travel order: place names or {latitude, longitude}. 2 to 25 items.
modestringNoHow the route is travelled. One of "driving", "walking", "cycling". Default "driving".
avoid_tollsbooleanNoDriving: avoid toll roads where a reasonable alternative exists. Default false.
avoid_highwaysbooleanNoDriving or cycling: avoid motorways and highways where possible. Default false.
avoid_ferriesbooleanNoAvoid ferries where possible. Default false.

Response

structuredContent holds the result, content the same result as text for a model, and isError is true when the tool refused the request or failed; then structuredContent.code, message and hint say what to change.

{
  "structuredContent": {
    "sources": [{ "name": "...", "licence": "...", "url": "..." }],
    "downloads": [{ "label": "...", "format": "...", "url": "...", "name": "..." }]
  },
  "content": [{ "type": "text", "text": "..." }],
  "isError": false
}

Every result lists its sources with their licence. File results come as downloads: each link builds its file when opened.

Errors

A missing key answers 401, an empty balance 402, too many calls 429. A call that fails or finds nothing is not counted. See Errors and rate limits.

Description for agents

The text the server gives an agent to decide when to call this tool:

Use this when the user wants the driving, walking or cycling route between 2 to 25 places or points in order: the distance and travel time along the roads and paths, per leg and in total, and the route line. Computed by Valhalla on the TerraLab server from the OpenStreetMap road network, with each road's typical speed. Options avoid tolls, highways or ferries. Returns the figures (distance_m, distance_km, duration_s, duration_min), a map of the line and GeoJSON, KML, GPX, Shapefile zip and GeoPackage downloads. Not for a straight-line distance (measure_distance or measure), live traffic, departure-time travel times, public transport or turn-by-turn navigation. Never use the user's current location unless they type it. Download links build their file when opened; no file is saved. Never pass these links to open_gis_file.
