MCP QUEEN

Compare database and PostgreSQL MCP servers

Find MCP servers for PostgreSQL, SQL, analytics, warehouses, and data access. Results are ranked by live operational probes—not affiliate placement or GitHub popularity.

Who this comparison is for

For developers and data teams choosing an agent connection to production or analytical databases.

What to verify before connecting

Confirm read-only or confirmation-gated modes before using production data.
Distinguish an open protocol handshake from database credentials and tool-level permissions.
Inspect typed schemas, provenance, latency, and the complete Trust Receipt before connecting.

30 currently graded matches · live observations last updated 2026-07-14 · ranked by operational score, then latency.

How MCP Queen ranks this list

These are live operational comparisons, not editorial endorsements. Grades measure reachability, protocol behavior, tool descriptions and schemas, latency, and provenance. Trust observations, response audits, and reviewed field reports remain separate; missing evidence means unaudited. There are no affiliate placements or paid rankings.
