Get current motor output values (PWM/DSHOT values)
AI agents call get_motor_values to retrieve information from Betaflight MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries current motor PWM/DSHOT values from the flight controller. It is a passive read operation that retrieves sensor/state data without side effects. No configuration changes, motor commands, or destructive actions are performed. Even in a drone context, reading motor values poses minimal risk—the worst case is information disclosure about current motor states.
From the tool's definition Tool name 'get_motor_values' and description 'Get current motor output values (PWM/DSHOT values)' explicitly indicate retrieval of telemetry data with no modification or control action.
Attacks that exploit this kind of access
Get current motor output values (PWM/DSHOT values). It is categorised as a Read tool in the Betaflight MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Betaflight MCP Server MCP server in PolicyLayer and add a rule for get_motor_values: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Betaflight MCP Server. Nothing to install.
get_motor_values is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_motor_values rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for get_motor_values. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
get_motor_values is provided by the Betaflight MCP Server MCP server (jir13/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
