Google Maps (internal web API)

by webmcp-today · v1 · updated 8/9/2026

*://www.google.com/maps*, *://google.com/maps*

Google Maps via the web app's own internal endpoints: place search, place details (ratings, hours, phone, website), driving directions, and — with a logged-in Google session — your saved lists and the places in them. No Google Cloud project, API key, or billing account required; search/details/directions also work logged out. NOTE: Maps responds with positional arrays, so these projections are the registry's loudest canary for API rot — when Google reshapes the payload the tools throw instead of answering wrong.

What changed in v1: Adds maps_lists and maps_list_places (signed-in only) alongside maps_search, maps_place_details, maps_directions. Requires engine support for `stripPrefix` (Google's anti-XSSI `)]}'` response marker).

Checking for the extension…

Installing saves v1 in your browser, not on your account. The extension registers its tools whenever you're on a matching page, and you stay on v1 until you update.

Needs the extension in a supported Chrome or Brave browser; the WebMCP testing flag is only needed for Chrome's native agent, not for the bridge. Get the extension →

  }
}

maps_listsread-only
List the signed-in user's saved Google Maps lists — Favorites, Want to go, Travel plans, and custom lists — with name, list id, type (1=custom, 2=Favorites, 3=Want to go, 5=Travel plans, 6=Saved places), and place count. Requires a logged-in Google session; fails logged out. Use a list id with maps_list_places.

  }
}
```

maps_list_placesread-only

List the places in one of the signed-in user's Google Maps lists: name, coordinates, and when each was added. Requires a logged-in session; get list ids from maps_lists. To open a listed place, search its name with maps_search and call maps_place_details with the hex feature_id from there — the decimal feature_id pair here is NOT accepted by maps_place_details.
