Google MCP Toolbox for Databases
Open-source MCP server from Google that connects AI agents to over 40 enterprise data sources. Handles connection pooling, authentication, and security so agents can interact with databases through natural language without custom integration code. Natively supports AlloyDB, Cloud SQL, Cloud Spanner, BigQuery, and many third-party data sources. Includes Java SDK for typesafe agent orchestration. Reached v1.0 in April 2026. Works with Claude, Cursor, and any MCP-compatible client. Part of the Google Cloud AI ecosystem.
