WHAT IT DOES

What pg_transaction_release does on PostgreSQL MCP Server

AI agents use pg_transaction_release to create or update resources in PostgreSQL MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your PostgreSQL MCP Server environment.

RISK

Why pg_transaction_release is rated Medium

Releasing a savepoint commits the changes made since the savepoint was established within the current transaction. This is a write/modification operation — it confirms partial transaction state changes — but is reversible at the outer transaction level if not yet committed. It does not delete data or execute arbitrary code, so Write is the most appropriate category.

From the tool's definition Release a savepoint, keeping all changes since it was created.

RECOMMENDED RULE

The rule that runs pg_transaction_release 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_transaction_release, this is the rule to start with:

pg_transaction_release Rate-limited

pg_transaction_release stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
