Best Postgres MCP Servers in 2026
Postgres is the single most-connected database in the MCP ecosystem, and the options range from the official reference server to full-featured forks with EXPLAIN analysis, connection pooling, and read-only enforcement.
When comparing, prioritize three things: a true read-only mode, schema introspection that goes beyond listing tables, and clear documentation of how the connection string is handled. The ranking below is ordered by adoption.

FAQ
Which Postgres MCP server should I pick?
Start with the highest-starred option below that explicitly documents a read-only mode. If you need multiple databases or connection pooling, check the multi-database entries in the broader database category.
How do I keep the agent from running writes?
Two layers: create a Postgres role with SELECT-only grants, and choose a server with a read-only flag. Either layer alone is common; both together is the recommended setup for shared databases.
Can it explain slow queries?
Several servers expose EXPLAIN output as a tool. Combined with the agent's reasoning, that turns "why is this endpoint slow" into a concrete index suggestion — check each server's tool list on its detail page.
