  "description": "Anthropic's reference PostgreSQL MCP was the first widely installed Postgres server but is no longer maintained. Anthropic archived the repository on 2025-07-10 at github.com/modelcontextprotocol/servers-archived, and Datadog Security Labs has documented a SQL-injection issue that bypasses the read-only restriction. New installs should use Postgres MCP Pro for tuning workflows or the Supabase MCP for Postgres-on-Supabase. This entry remains so existing users can find the migration path.",
