WHAT IT DOES

What k1_grip does on Execution Market

AI agents invoke k1_grip to trigger actions in Execution Market. 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.

RISK

Why k1_grip is rated High

This tool actuates physical hardware (grippers) with a specified force and duration, triggering a real-world physical operation. It falls under Execute as it runs an external physical action whose effects depend on the arguments (force and duration). The blast radius is high because incorrect force or duration could cause physical damage to objects, equipment, or people in the real world.

From the tool's definition Close the grippers at ``force`` N for ``duration_s`` seconds.

RECOMMENDED RULE

The rule that runs k1_grip safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Execution Market, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For k1_grip, this is the rule to start with:

k1_grip Rate-limited

k1_grip stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

The button opens the PolicyLayer dashboard: create your workspace, connect Execution Market, apply this rule, and every k1_grip call is checked against it from then on.
