WHAT IT DOES

What bar_visibility_set does on Omarchy-MCP

AI agents invoke bar_visibility_set 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 bar_visibility_set is rated High

Triggers a desktop UI state change and modifies an on-disk flag.

RECOMMENDED RULE

The rule that runs bar_visibility_set 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 bar_visibility_set, this is the rule to start with:

bar_visibility_set Rate-limited

bar_visibility_set 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 Omarchy-MCP, apply this rule, and every bar_visibility_set call is checked against it from then on.
