AI agents use create_xcode_project to create or update resources in Xcode — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Xcode environment.
This tool creates new files and project structures on disk, which is a reversible write operation. While it modifies the file system, project creation can be undone by deleting the generated files. It does not execute arbitrary code, delete data irreversibly, or involve financial transactions.
From the tool's definition Tool description: 'Creates a new Xcode project using a template.' The verb 'creates' indicates data generation and modification of the file system by adding new project files and directories.
Documented attack patterns abuse exactly the kind of access create_xcode_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 create_xcode_project:
{
"version": "1",
"default": "deny",
"tools": {
"create_xcode_project": {
"limits": [
{
"counter": "create_xcode_project_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_xcode_project 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.
Free to start. No card required.
Creates a new Xcode project using a template. It is categorised as a Write tool in the Xcode MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Xcode MCP server in PolicyLayer and add a rule for create_xcode_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.
create_xcode_project 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 create_xcode_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 create_xcode_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.
create_xcode_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.
