gt_sling · Claude Flow MCP: Risk & Policy

WHAT IT DOES

What gt_sling does on Claude Flow

AI agents use gt_sling to create or update resources in Claude Flow — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Claude Flow environment.

WHY IT NEEDS A POLICY

Why gt_sling needs a policy

The tool assigns/routes a work item ('bead') to an agent for processing, which is a write/scheduling operation creating an assignment record. No indication of irreversible deletion, code execution, or financial action. Severity is medium because misrouting work items in an enterprise orchestration system could cause unintended agent actions, but the operation itself appears reversible.

Verdict

gt_sling Rate-limited

gt_sling stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
