Attempts to automatically detect the active Xcode project.
AI agents call detect_active_project 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.
The tool performs discovery of the active project context, which is a read-only operation. It gathers information needed for other operations but has no side effects. No data is created, modified, executed, or destroyed.
From the tool's definition Tool 'detect_active_project' attempts to automatically detect the active Xcode project. This is a query/detection operation that retrieves information about the current project state without modifying, executing, or deleting anything.
Documented attack patterns abuse exactly the kind of access detect_active_project 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 detect_active_project:
{
"version": "1",
"default": "deny",
"tools": {
"detect_active_project": {}
}
}detect_active_project is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Attempts to automatically detect the active Xcode project. 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 detect_active_project: 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.
detect_active_project 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 detect_active_project 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 detect_active_project. 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.
detect_active_project 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.
