Postgres brake for AI agents: risky SQL waits for approval, UPDATE/DELETE get one-command undo.

What it does

pgbrake is an MCP server, a connector that lets an AI assistant use it as a tool. It is installed locally as a package and runs on your machine.

From the publisher's description, Electra Index matched it to one capability: sql querying. That makes it a candidate for tasks such as query databases in plain language or build data pipelines.

Facts come from the Official MCP Registry, as declared by the publisher. Capabilities are matched automatically (low confidence). None of this is a test of the tool.
