xcode_set_simulator_location

THE RISK

High Risk

This tool modifies the runtime state of an iOS simulator by spoofing its geographic location. It is not a simple data write (reversible config change) but rather an execution of a device-level command that affects how apps behave during testing. It fits Execute because it triggers an external operation (Xcode/Appium simulator command) whose effects depend on the provided coordinates.

From the tool's definition 'Set the location of a simulator' — actively changes the simulator's GPS/location state, triggering an external operation on the device environment

HOW TO CONTROL XCODE_SET_SIMULATOR_LOCATION

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_set_simulator_location:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "xcode_set_simulator_location": {
      "limits": [
        {
          "counter": "xcode_set_simulator_location_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

xcode_set_simulator_location 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.

Create a free account and register MCP Appium Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

What does the xcode_set_simulator_location tool do? +

Set the location of a simulator. It is categorised as a Execute tool in the MCP Appium Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on xcode_set_simulator_location? +

Register the MCP Appium Server MCP server in PolicyLayer and add a rule for xcode_set_simulator_location: 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.

What risk level is xcode_set_simulator_location? +

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

Can I rate-limit xcode_set_simulator_location? +

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

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

xcode_set_simulator_location 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.

Enforce policy on every MCP Appium Server tool call.
