Implementation Reference

• src/gcp_mcp/gcp_modules/databases/tools.py:230-272 (handler)

  The handler function for the 'list_firestore_databases' tool. It uses the FirestoreAdminClient to list all Firestore databases in the specified GCP project, formats them by name, type, and location, and returns a formatted string list.
