WHAT IT DOES

What start_auto_refresh does on Code Expert MCP Server

AI agents invoke start_auto_refresh to trigger actions in Code Expert 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 start_auto_refresh needs a policy

This tool triggers execution of a background system (auto-refresh) rather than merely reading or writing static data. While it does not directly execute arbitrary user-supplied code like execute_script would, it starts an autonomous process that will perform operations (likely fetching/updating repository data) based on configuration.

From the tool's definition Tool performs 'Manually start auto-refresh system' — an action that triggers an automated process. The verb 'start' indicates initiation of an operation whose effects depend on the auto-refresh system's configured behavior and scope.
