pgbrake MCP

A local MCP server for Postgres that acts as a safety brake for AI agents. It intercepts risky SQL writes like DELETE or UPDATE without WHERE clauses, requiring human approval before execution. It also provides one-command undo functionality for affected rows and maintains an audit log of all statements.
