# PostgreSQL MCP servers

MCP servers that let an agent inspect schemas and run queries on PostgreSQL databases.

## Before you choose

Most PostgreSQL servers are local packages (L0) that connect with a database URL you provide, so they reach databases on your own network; remote ones need the database to be reachable from their host.

Give the agent a read-only database role unless it really has to write, and check whether the server marks its query tools as read-only.
