Koskamo

PostgreSQL MCP Server

An open-source MCP server that provides agents with read-only-by-default access to PostgreSQL databases. It supports parameterized SQL queries, schema and view introspection, EXPLAIN plans with index advice, and performance diagnostics like health checks and lock inspection. Writes are opt-in via an environment variable to prevent accidental data modification.
