MCP Toolbox for Databases is an open source Model Context Protocol (MCP) server, written in Go, that connects AI agents, IDEs, and applications to enterprise databases. It offers prebuilt generic tools for instant data exploration plus a custom tools framework for defining secure, production-ready queries, semantic search, and NL2SQL capabilities via a tools.yaml configuration.
Use cases
- connect Claude Code or Gemini CLI to my postgres database via MCP
- let an AI agent query BigQuery or Spanner safely
- build custom secure database tools for a production LLM agent
- explore database schemas and run SQL from my IDE with an MCP client
- add NL2SQL and semantic search tools to a LangChain or ADK agent
- expose MongoDB or Elasticsearch data to AI agents with authentication
When to choose
- you want a ready-made MCP server bridging AI agents/IDEs and many database engines
- you need secure, parameterized, authenticated database tools for production agents
- you use Google Cloud databases (BigQuery, Spanner, Firestore) or popular engines like Postgres, MySQL, MongoDB, Redis
- you want connection pooling, IAM auth, and OpenTelemetry observability handled for you
When to avoid
- you need a generic MCP server for non-database tools or APIs
- you want a lightweight embedded library rather than a separately deployed server
- your database engine is not among the supported sources
- you require fully arbitrary LLM-generated SQL in production without developer oversight
