set_print_speed · Bambu Printer MCP: Risk & Policy

WHAT IT DOES

What set_print_speed does on Bambu Printer

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

WHY IT NEEDS A POLICY

Why set_print_speed needs a policy

This tool modifies an active printer setting (print speed mode) during a print job. It is reversible (the speed can be changed back), so it falls under Write rather than Destructive or Execute. Misuse could affect print quality or cause print failures, giving it medium severity.

From the tool's definition Set the active print speed mode: silent, standard, sport, or ludicrous.
