Verdicts

Google Maps Platform + Grounding Lite MCP

Maps Grounding Lite is GA, hosted, and takes an X-Goog-Api-Key header or OAuth with the maps-platform.mapstools scope. A Cloud billing account with a payment method is required before the free caps apply.

Stadia Maps

Public OpenAPI spec (11.1.0) with generated TypeScript and Python SDKs. Free plan is for development, testing and demos only.

Before you call either

Google Maps Platform + Grounding Lite MCP

  1. Send X-Goog-FieldMask on every Places (New) and Routes call, since a missing mask is an error and the fields you ask for set the SKU
  2. Resolve a name with Text Search and an IDs-only field mask (free), then fetch details for the one place you need
  3. Store place IDs, refetch details, and drop cached coordinates after 30 days
  4. Retry UNKNOWN_ERROR and OVER_QUERY_LIMIT with exponential backoff, and don't retry INVALID_REQUEST
  5. Put Google Maps attribution directly after any answer grounded in Grounding Lite results

Stadia Maps

  1. Send the key as Authorization: Stadia-Auth <key> rather than in the URL
  2. Try Autocomplete v2 (1 credit) before a full geocode (20 credits) when a name is enough
  3. Check the dashboard's credit balance before retrying a 429, since it may mean the month is spent
  4. Don't write geocodes to a database on Free or Starter
  5. Use bulk-geocode for addresses only, not POI names
