What list_workers does on Cloudflare Control

AI agents call list_workers to retrieve information from Cloudflare Control without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Why list_workers needs a policy

This tool only lists/queries existing Workers scripts—a read operation with no side effects. While Workers can execute code, merely listing them reveals only metadata about deployed scripts, not their execution. The blast radius is low: the information disclosed is limited to names and basic metadata of the user's own Workers, which does not enable unauthorized actions without additional exploit steps.

From the tool's definition Tool name 'list_workers' and description 'List all Cloudflare Workers scripts deployed in an account' indicate a read-only operation that retrieves and enumerates existing Workers without modification.
