Getting started with MCP Toolbox for Databases
summary
MCP Toolbox for Databases is an open source Go service (GitHub) that connects LLM agents to Cloud SQL, AlloyDB and BigQuery with production features: 15,000 stars and millions of monthly tool calls, connection pooling, prepared statements, and OpenTelemetry. It enforces authenticated parameters and bound parameters via OAuth to prevent confused‑deputy leaks, supports build‑time and runtime tools, progressive disclosure/skills, and can run on Cloud Run; the Cymbal Flowers demo shows booking flights while preserving signer identity.
