A Go-based MCP server that links agents and MCP clients (Gemini CLI, Claude Code, Codex) to databases spanning Google Cloud's AlloyDB, BigQuery, Cloud SQL, and Spanner plus PostgreSQL, MySQL, SQL Server, MongoDB, and many more. Use the prebuilt generic tools like list_tables and execute_sql to explore schemas at build time, or define custom production tools in a tools.yaml. It adds connection pooling, IAM auth, and OpenTelemetry observability, and integrates with ADK, LangChain, and LlamaIndex.
