set_orientation · React Native MCP: Risk & Policy

WHAT IT DOES

What set_orientation does on React Native

AI agents invoke set_orientation to trigger actions in React Native. 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 set_orientation needs a policy

This tool triggers an external operation on a device/simulator by changing its physical orientation state. It doesn't read data, write persistent data, or destroy anything, but it does execute a device-level action with side effects on the running environment. Misuse potential is low as it only affects display orientation.

Verdict

set_orientation Rate-limited

set_orientation 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 React Native, so you can run agents against it safely.

FAQ

Questions about set_orientation

What does the set_orientation tool do? +

Set device orientation to portrait or landscape. iOS: simulator only. It is categorised as a Execute tool in the React Native MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on set_orientation? +

Register the React Native MCP server in PolicyLayer and add a rule for set_orientation: 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 React Native. Nothing to install.

What risk level is set_orientation? +

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

Can I rate-limit set_orientation? +

Yes. Add a rate_limit block to the set_orientation 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_orientation completely? +

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

set_orientation is provided by the React Native MCP server (@ohah/react-native-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
