AI agents call get_file_info to retrieve information from Xcode without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves file/directory metadata without creating, modifying, deleting, or executing any operations. It is a pure read operation with minimal blast radius if misused by an AI agent.
From the tool's definition Tool name 'get_file_info' and description 'Gets detailed information about a file or directory' indicate retrieval of metadata with no modification or side effects.
Documented attack patterns abuse exactly the kind of access get_file_info gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Xcode, and nothing reaches the server without passing your rules. This is the rule we recommend for get_file_info:
{
"version": "1",
"default": "deny",
"tools": {
"get_file_info": {}
}
}get_file_info is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Gets detailed information about a file or directory. It is categorised as a Read tool in the Xcode MCP Server, which means it retrieves data without modifying state.
Register the Xcode MCP server in PolicyLayer and add a rule for get_file_info: 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 Xcode. Nothing to install.
get_file_info is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_file_info 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 get_file_info. 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.
get_file_info is provided by the Xcode MCP server (xcode-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
