PostgreSQL Gateway FAQs

Question 1

What is PostgreSQL Gateway?

Accepted Answer

PostgreSQL Gateway is an MCP (Model Context Protocol) server that provides AI agents (e.g., Claude Code, Cursor) with secure, strictly read-only access to PostgreSQL databases, allowing them to execute queries and explore database objects safely.

Question 2

How does PostgreSQL Gateway enforce read-only access?

Accepted Answer

It enforces read-only mode at two critical levels: a SQL parser validates that only SELECT, WITH, EXPLAIN, and SHOW queries are allowed, and further read-only mode is enforced at the PostgreSQL database connection level itself.

Question 3

Which AI agents and tools are compatible with PostgreSQL Gateway?

Accepted Answer

PostgreSQL Gateway is compatible with AI agents and tools that support the Model Context Protocol (MCP), including popular platforms like Claude Code, Cursor, and VS Code.

Question 4

What types of SQL operations can AI agents perform?

Accepted Answer

AI agents can execute read-only SQL queries (SELECT, WITH, EXPLAIN, SHOW) and use the `pg_search_objects` tool to discover database schemas, tables, columns, indexes, and procedures.

Question 5

How does it handle large query results and ensure security?

Accepted Answer

The gateway automatically truncates large query results via row limiting (configurable) to prevent overload. Security is managed through API Key authentication, rate limiting, and the robust double-layer read-only enforcement.
