rotate · Phantom MCP: Risk & Policy

WHAT IT DOES

What rotate does on Phantom

AI agents invoke rotate to trigger actions in Phantom. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why rotate needs a policy

Rotating a device or simulator orientation is an external operation that changes device state. It fits Execute as it triggers an action on an external system (mobile device/simulator). The description is truncated and uninformative, lowering confidence. Severity is medium given the blast radius is limited to device orientation state.

From the tool's definition Tool name 'rotate' and truncated description 'Change l' — likely 'Change [device orientation/layout]', triggering a device state change on a simulator/emulator or real device.

Verdict

rotate Rate-limited

rotate stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches Phantom, so you can run agents against it safely.

FAQ

Questions about rotate

What does the rotate tool do? +

Change l. It is categorised as a Execute tool in the Phantom MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on rotate? +

Register the Phantom MCP server in PolicyLayer and add a rule for rotate: 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 Phantom. Nothing to install.

What risk level is rotate? +

rotate is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit rotate? +

Yes. Add a rate_limit block to the rotate 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 rotate completely? +

Set action: deny in the PolicyLayer policy for rotate. 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 rotate? +

rotate is provided by the Phantom MCP server (nthimpulse/phantom-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
