pulse_vibe · LLV Helix Framework MCP: Risk & Policy

WHAT IT DOES

What pulse_vibe does on LLV Helix Framework

AI agents invoke pulse_vibe to trigger actions in LLV Helix Framework. 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 pulse_vibe needs a policy

The tool actively 'sends a pulse' which implies triggering some operation or state change rather than merely reading data. Within the LLV Helix Framework context, vibes represent energy states, so pulsing one likely modifies or triggers state transitions. This aligns with Execute (triggering external operations) or at minimum Write. The description is vague, lowering confidence.

From the tool's definition 'Send a pulse through a vibe' — triggers an external operation/action on a named entity (vibe)

pulse_vibe Rate-limited

pulse_vibe 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.
