licensing_sync · CyPerf MCP Server MCP: Risk & Policy

WHAT IT DOES

What licensing_sync does on CyPerf MCP Server

AI agents invoke licensing_sync to trigger actions in CyPerf MCP Server. 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 licensing_sync needs a policy

Synchronizing licenses triggers an external operation against a license server — it actively communicates with and updates state on a remote system. This is not a simple read, nor does it irreversibly delete data, but it executes an action with external side effects (refreshing/updating license entitlements). Misuse could disrupt licensing state or trigger unintended license consumption.

Verdict

licensing_sync Rate-limited

licensing_sync 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.
