wait_for_sync · Codesearch MCP: Risk & Policy

WHAT IT DOES

What wait_for_sync does on Codesearch

AI agents invoke wait_for_sync to trigger actions in Codesearch. 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 wait_for_sync needs a policy

Based on the name alone, this tool likely initiates or waits for an external operation (code indexing/synchronization), which qualifies as Execute. However, the empty description and lack of detail on what 'sync' entails reduces confidence. The low severity reflects that synchronization operations are typically non-destructive maintenance tasks with minimal blast radius if invoked unnecessarily.

From the tool's definition Tool name 'wait_for_sync' suggests it triggers or awaits a synchronization operation. The description is empty, providing no clarification of its actual behavior.
