PostgreSQL MCP Server FAQ

Is PostgreSQL MCP Server safe to use?

No. This server is officially deprecated due to a critical SQL injection vulnerability. The server passes user input directly to the database without proper sanitization. Use Supabase MCP or Neon MCP as safer alternatives.

What was PostgreSQL MCP Server designed to do?

It allowed AI agents to run SQL queries against a PostgreSQL database, inspect schemas, list tables, and describe table structures. It connected via a standard DATABASE_URL connection string.

Why was PostgreSQL MCP Server deprecated?

A SQL injection vulnerability was discovered that allows arbitrary SQL execution through crafted tool inputs. Since AI agents can be prompt-injected, this creates a serious risk of data loss or exfiltration on any connected database.

What should I use instead of PostgreSQL MCP Server?

Use Supabase MCP (with built-in RLS and read-only modes), Neon MCP Server (with branching for safe experimentation), or write a custom MCP server with parameterized queries and strict input validation.

Can I still install PostgreSQL MCP Server?

The package @anthropic-ai/postgresql-mcp still exists on npm but is no longer maintained. Installing it is strongly discouraged. If you must access PostgreSQL from AI agents, use a server with proper query parameterization.
