WHAT IT DOES

What pg_pgcrypto_gen_salt does on PostgreSQL MCP Server

AI agents invoke pg_pgcrypto_gen_salt to trigger actions in PostgreSQL MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why pg_pgcrypto_gen_salt is rated High

This tool executes a cryptographic operation (salt generation) on the PostgreSQL server via the pgcrypto extension. It doesn't read, write, or delete data, but it does trigger an execution of a server-side function. The blast radius is low since it only generates a random salt value with no side effects on data or system state.

RECOMMENDED RULE

The rule that runs pg_pgcrypto_gen_salt safely

PolicyLayer is an MCP gateway: it sits between your AI agents and PostgreSQL MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For pg_pgcrypto_gen_salt, this is the rule to start with:

pg_pgcrypto_gen_salt Rate-limited

pg_pgcrypto_gen_salt stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
