WHAT IT DOES

What executeDatabase does on Cloudflare Remote PostgreSQL Database MCP Server

AI agents invoke executeDatabase to trigger actions in Cloudflare Remote PostgreSQL Database 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.

WHY IT NEEDS A POLICY

Why executeDatabase needs a policy

While the tool can technically perform Destructive operations (DELETE, DDL), the primary category should be Execute because: (1) the tool's core function is to execute arbitrary SQL statements with side effects dependent on the specific statement provided as an argument, (2) it requires privileged authentication (GitHub OAuth restriction), (3) the threat model depends on what SQL an AI agent constructs, not inherent…

From the tool's definition Tool description states "Execute any SQL statement against the PostgreSQL database, including INSERT, UPDATE, DELETE, and DDL operations" and "can perform write transactions".
