Best for
  • Developers with data already in Firebase who want AI assistants to read and write it directly
  • Users of MCP clients such as Claude Desktop, Cursor, VS Code, or Augment Code
  • Workflows combining document database, file storage, and user lookup
  • Teams already using ClickHouse who want AI assistants to access data directly.
  • Scenarios requiring fast, read-only data queries and schema exploration.
Not for
  • Users without a Firebase project or service account credentials
  • Firebase administration tasks such as project management or function deployment
  • Environments without an MCP client or the ability to configure environment variables
  • Scenarios requiring write access to the database without explicit opt-in.
  • Production environments with stringent security requirements that avoid default permission settings.
Required permissions
  • Requires a Firebase service account private key JSON file (SERVICE_ACCOUNT_KEY_PATH)
  • The service account must have proper permissions for Firestore, Storage, and Authentication services
  • Requires a Firebase Storage bucket name, either configured or defaulted
  • Requires read-only access to ClickHouse database (default).
  • Optional: write access via CLICKHOUSE_ALLOW_WRITE_ACCESS.
  • Optional: destructive operations via CLICKHOUSE_ALLOW_DROP.
Risks and side effects
  • Service account private keys carry broad privileges; misconfiguration or leakage can expose full data access
  • AI assistants can delete Firestore documents and upload/overwrite storage files, creating risk of unintended operations
  • The firestore_list_collections tool may trigger a Zod validation error in client logs (a known MCP SDK issue that does not affect functionality but may cause confusion)
  • Some Firestore queries require manually creating composite indexes in the Firebase Console
  • If write access is enabled, AI might make unintended modifications.
  • If DROP access is enabled, data deletion could occur accidentally.
  • Credentials may be exposed via environment variables.
