Google's open source MCP server for databases. Instead of shipping a fixed tool list, you declare each tool in a tools.yaml file — its source, the statement it runs and the parameters it accepts — so an agent only ever sees the queries you approved. One server process handles connection pooling, credentials and authorisation for every source it is given, which keeps that plumbing out of the agent. Sources include PostgreSQL, MySQL, SQL Server, MongoDB, Redis, Elasticsearch, Neo4j, ClickHouse and Snowflake alongside Google Cloud databases such as AlloyDB, Cloud SQL, Spanner, Firestore and BigQuery.
