MCP Toolbox for Databases

What it does

MCP Toolbox for Databases is Google's open-source MCP server for connecting AI clients and agents to databases. Started with a prebuilt flag, it offers ready tools such as listing tables and running SQL against Google Cloud databases including AlloyDB, BigQuery, Cloud SQL, Spanner and Firestore, and against others such as PostgreSQL, MySQL, SQL Server, Oracle, MongoDB, Redis, Snowflake and Neo4j. Teams can also define their own tools in a tools.yaml file and load them into ADK, LangChain or LlamaIndex agents through Python, JavaScript, Go and Java SDKs. It runs over stdio through npx or as a local HTTP server. The repository was renamed from genai-toolbox to mcp-toolbox.
