claims_claim · Claude Flow MCP: Risk & Policy

WHAT IT DOES

What claims_claim does on Claude Flow

AI agents invoke claims_claim to trigger actions in Claude Flow. 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 claims_claim needs a policy

The tool manages capability gating and access control for agent execution of privileged operations. While not directly executing code itself, it enables or authorizes execution flows and determines what operations an agent can perform.

From the tool's definition Tool description states: 'Claim an issue for work (human or agent)' and 'Pair claims_grant + claims_check before letting an agent run privileged ops.' This indicates the tool is used to gate and control execution of privileged operations by agents.
