set_scan_rotation · mcpXL30 MCP: Risk & Policy

WHAT IT DOES

What set_scan_rotation does on mcpXL30

AI agents use set_scan_rotation to create or update resources in mcpXL30 — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your mcpXL30 environment.

WHY IT NEEDS A POLICY

Why set_scan_rotation needs a policy

Based on the tool name, it likely sets the scan rotation angle of the electron beam/scan system on the ESEM microscope. This is a reversible write operation (adjusting a parameter), but the empty description lowers confidence. Given the server context of microscope control with a safety envelope, misuse could affect imaging quality or specimen interaction, but is unlikely to be destructive or irreversible.

From the tool's definition Tool name 'set_scan_rotation' on a microscope control server; description is empty and uninformative.
