assign_switch · Betaflight MCP Server MCP: Risk & Policy

WHAT IT DOES

What assign_switch does on Betaflight MCP Server

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

WHY IT NEEDS A POLICY

Why assign_switch needs a policy

This tool modifies drone flight controller settings by binding switch inputs to flight mode channels. While not destructive (changes are reversible via reconfiguration), it is a Write action that alters active configuration. Severity is medium because misuse could cause unexpected flight mode activation during flight (safety risk), but the change can be undone and doesn't directly cause data loss or financial impact.

From the tool's definition Asignar un switch (SA-SF) a un canal AUX para un modo de vuelo - the tool assigns/maps a physical switch to an auxiliary channel for flight mode control, modifying flight controller configuration.
