Configure simulator preferences in batch
AI agents use xcode_configure_simulator_preferences to create or update resources in MCP Appium Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your MCP Appium Server environment.
This tool modifies simulator preferences, which are settings that can be changed and reverted. It does not delete data (not Destructive), does not execute arbitrary code or shell commands (not Execute—it configures preferences rather than runs arbitrary commands), involves no financial operations (not Financial), and performs data manipulation rather than simple retrieval (not Read).
From the tool's definition Tool name 'xcode_configure_simulator_preferences' with description 'Configure simulator preferences in batch' indicates modification of simulator configuration settings.
Documented attack patterns abuse exactly the kind of access xcode_configure_simulator_preferences gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and MCP Appium Server, and nothing reaches the server without passing your rules. This is the rule we recommend for xcode_configure_simulator_preferences:
{
"version": "1",
"default": "deny",
"tools": {
"xcode_configure_simulator_preferences": {
"limits": [
{
"counter": "xcode_configure_simulator_preferences_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}xcode_configure_simulator_preferences 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.

Configure simulator preferences in batch. It is categorised as a Write tool in the MCP Appium Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the MCP Appium Server MCP server in PolicyLayer and add a rule for xcode_configure_simulator_preferences: 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 MCP Appium Server. Nothing to install.
xcode_configure_simulator_preferences is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the xcode_configure_simulator_preferences 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 xcode_configure_simulator_preferences. 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.
xcode_configure_simulator_preferences is provided by the MCP Appium Server MCP server (rahulec08/appium-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
