Pure math: calculate max rotation rate (deg/s) for given rate settings.
AI agents call calculate_max_rate 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 performs only mathematical calculations on provided parameters and returns a computed value. It retrieves no data from the drone, modifies no configuration, executes no commands, and triggers no physical actions. It is purely a Read operation (computational analysis) with minimal security risk. The low severity reflects that misuse cannot damage the drone, delete data, or cause financial harm.
From the tool's definition Tool description explicitly states 'Pure math: calculate max rotation rate (deg/s) for given rate settings.' This is a computational function that takes inputs and returns a calculated result with no side effects, data modifications, or external operations.
Attacks that exploit this kind of access
Pure math: calculate max rotation rate (deg/s) for given rate settings. 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 calculate_max_rate: 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.
calculate_max_rate 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 calculate_max_rate 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 calculate_max_rate. 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.
calculate_max_rate 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.
