simulator_set_locale

Set the device locale and language for internationalization testing. Requires device reboot to take effect.

Part of the Preflight Ios MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.

// WHEN AI AGENTS USE THIS TOOL

AI agents use simulator_set_locale to create or modify resources in Preflight Ios. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.

// WHY ENFORCE A POLICY ON SIMULATOR_SET_LOCALE

Without a policy, an AI agent could call simulator_set_locale repeatedly, creating or modifying resources faster than any human could review. Intercept's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Preflight Ios.

// RECOMMENDED POLICY

Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

What does the simulator_set_locale tool do? +

Set the device locale and language for internationalization testing. Requires device reboot to take effect.. It is categorised as a Write tool in the Preflight Ios MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on simulator_set_locale? +

Add a rule in your Intercept YAML policy under the tools section for simulator_set_locale. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Preflight Ios MCP server.

What risk level is simulator_set_locale? +

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

Can I rate-limit simulator_set_locale? +

Yes. Add a rate_limit block to the simulator_set_locale rule in your Intercept 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 simulator_set_locale completely? +

Set action: deny in the Intercept policy for simulator_set_locale. 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 simulator_set_locale? +

simulator_set_locale is provided by the Preflight Ios MCP server (preflight-ios-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
