7 TOOLS AVAILABLE
OUR ASSESSMENT
- 14,937 GitHub stars, top of the database category.
- 100 commits on main in the last 30 days. Highest cadence in the directory.
- One MCP binary speaks seven database backends.
- Apache-2.0 license, Google official maintenance.
- Go binary, no Python or Node runtime required.
- tools.yaml config reuses across teams; per-tool authorisation rules supported.
- Configuration via tools.yaml steeper than single-database MCPs that auto-detect from a single env var.
- Per-database tool surfaces vary; check the docs for the exact surface per backend before mounting in production.
- Go binary requires a release artefact path on disk, less portable than npx-installed MCP servers.
tools.yaml carries database credentials. Store outside the repo and inject via secret manager. Read-only tools (run_query, list_tables) should be the default surface; execute_sql carries write capability and should be gated to specific databases or roles.
Multi-database teams (Postgres + BigQuery, MySQL + Spanner) wanting one MCP server instead of seven; Google Cloud-heavy stacks adopting agentic database workflows; platform teams standardising on Apache-2.0 vendor-official tooling.

// Reading thisTop of the database category by star count and cadence. Pairs with single-vendor MCPs (Postgres, MongoDB, Redis, Neo4j) for teams that want both single-DB and multi-DB MCP surfaces available.
SOURCES & VERIFICATION
We don't take any single directory's word for it. Before scoring, we cross-reference 5 public MCP sources, install the server ourselves against the clients we cover, and record when we last re-verified.
The same server, 5 different lenses. We reconcile these signals into our editorial score, which is why our number sometimes diverges from a directory-aggregate star count.
