set_pid_profile · Betaflight MCP Server MCP: Risk & Policy

WHAT IT DOES

What set_pid_profile does on Betaflight MCP Server

AI agents use set_pid_profile 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 set_pid_profile needs a policy

This is a Write operation because it modifies drone flight controller state (the active PID profile) reversibly. While it affects drone behavior significantly, the change is not destructive (profiles can be switched back or restored from backups). It is not Execute because it doesn't run arbitrary code or trigger real-time flight actions.

From the tool's definition Tool switches PID profiles on a drone flight controller, modifying the active configuration that controls flight dynamics. The name 'set_pid_profile' and description 'Switch to a different PID profile' indicate a configuration change operation.

Verdict

set_pid_profile Rate-limited

set_pid_profile stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about set_pid_profile

What does the set_pid_profile tool do? +

Switch to a different PID profile. It is categorised as a Write tool in the Betaflight MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on set_pid_profile? +

Register the Betaflight MCP Server MCP server in PolicyLayer and add a rule for set_pid_profile: 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.

What risk level is set_pid_profile? +

set_pid_profile is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit set_pid_profile? +

Yes. Add a rate_limit block to the set_pid_profile 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.

How do I block set_pid_profile completely? +

Set action: deny in the PolicyLayer policy for set_pid_profile. 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.

What MCP server provides set_pid_profile? +

set_pid_profile 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.
