What's Good

Apache-2.0, from Google (googleapis/mcp-toolbox), release v1.14.0. Prebuilt generic tools such as list_tables and execute_sql get an MCP client talking to a database in minutes; for production you define your own parameterised SQL tools in tools.yaml. Works with Postgres, MySQL and many more, plus Google Cloud databases. ★~16.6k.

The Catch

You write and maintain your SQL tools yourself in tools.yaml — the server does not invent safe queries for you. The prebuilt tool sets mostly target Google databases (AlloyDB, Cloud SQL, BigQuery, Spanner and friends); other engines get the generic tools. Renamed from genai-toolbox, so older guides use the old name.

Verdict

The Google-backed way to give agents database access through queries you control — budget time for writing tools.yaml.
