reset_view · ChimeraX MCP Server MCP: Risk & Policy

WHAT IT DOES

What reset_view does on ChimeraX MCP Server

AI agents invoke reset_view to trigger actions in ChimeraX 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 reset_view needs a policy

This tool triggers an external operation in ChimeraX (resetting the camera/viewport state), which is an action in the visualization application rather than a simple data read. It modifies the view state of the running application, making it an Execute action. The blast radius is low as it only affects the current viewing perspective and is easily reversible by the user.

Verdict

reset_view Rate-limited

reset_view 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.
