WHAT IT DOES

What obj_zoom does on Altium-MCP-Suite

AI agents invoke obj_zoom to trigger actions in Altium-MCP-Suite. 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 obj_zoom is rated High

This tool triggers an external operation within Altium Designer (changing the viewport zoom), which affects the application's UI state. It's not purely a read operation since it modifies the view state, but it doesn't write/modify design data, making Execute the most appropriate category. Blast radius is low as it only affects the display/viewport.

RECOMMENDED RULE

The rule that runs obj_zoom safely

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

obj_zoom Rate-limited

obj_zoom 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 Altium-MCP-Suite, apply this rule, and every obj_zoom call is checked against it from then on.
