Check if xctrace is available and get version information
AI agents call check_xctrace to retrieve information from XcodeTraceMCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only checks availability and retrieves version metadata about the xctrace binary. It has no side effects, performs no modifications, and poses minimal security risk. It is purely informational in nature, fitting the Read category for tools that retrieve data without side effects.
From the tool's definition The tool "check_xctrace" with description "Check if xctrace is available and get version information" performs a pure query operation that retrieves version information without modifying any state.
Documented attack patterns abuse exactly the kind of access check_xctrace gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and XcodeTraceMCP, and nothing reaches the server without passing your rules. This is the rule we recommend for check_xctrace:
{
"version": "1",
"default": "deny",
"tools": {
"check_xctrace": {}
}
}check_xctrace is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Check if xctrace is available and get version information. It is categorised as a Read tool in the XcodeTraceMCP MCP Server, which means it retrieves data without modifying state.
Register the XcodeTrace MCP server in PolicyLayer and add a rule for check_xctrace: 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 XcodeTraceMCP. Nothing to install.
check_xctrace 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 check_xctrace 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 check_xctrace. 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.
check_xctrace is provided by the XcodeTrace MCP server (jamesrochabrun/xcodetracemcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from XcodeTraceMCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
