karea_ask · Karea MCP: Risk & Policy

WHAT IT DOES

What karea_ask does on Karea

AI agents invoke karea_ask to trigger actions in Karea. 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 karea_ask needs a policy

This tool sends a natural language message to an AI system, which triggers external operations whose effects depend on the message content. Since the AI could perform various actions (read, write, or other operations) based on the message, Execute is the most appropriate category. The exact blast radius is uncertain because it depends on what the AI does with the message, lowering confidence slightly.
