WHAT IT DOES

What update_system does on Omarchy-MCP

AI agents invoke update_system to trigger actions in Omarchy-MCP. 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 update_system is rated High

Executes system-wide update workflow with dangerous flag, broad uncontrollable side effects.

RECOMMENDED RULE

The rule that runs update_system safely

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

update_system Rate-limited

update_system 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.

What risk level is update_system? +

update_system is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit update_system? +

Yes. Add a rate_limit block to the update_system rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block update_system completely? +
