AI agents use xcode_add_media_to_simulator 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 creates/adds media files (photos/videos) to a simulator environment. It is a write operation that modifies the simulator's media library by adding new content. It is reversible (media can be deleted), so it does not qualify as Destructive. The blast radius is medium as it only affects a simulator environment, not production data.
From the tool's definition Add photos/videos to a simulator
Documented attack patterns abuse exactly the kind of access xcode_add_media_to_simulator 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_add_media_to_simulator:
{
"version": "1",
"default": "deny",
"tools": {
"xcode_add_media_to_simulator": {
"limits": [
{
"counter": "xcode_add_media_to_simulator_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}xcode_add_media_to_simulator 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.

Add photos/videos to a simulator. 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_add_media_to_simulator: 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_add_media_to_simulator 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_add_media_to_simulator 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_add_media_to_simulator. 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_add_media_to_simulator 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.
