xcf-user-guide

A guide for installing and configuring XCF, a Swift-based server that lets AI assistants automate tasks in Xcode, Apple's development environment.

In plain words
What is it for?
Use it to install the application, configure its Model Context Protocol server entry, codesign it when needed, and work with Xcode automation.
Why use it?
It collects the setup, configuration, and testing information needed to connect XCF to supported AI clients on macOS.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Made for: Cursor.

Per session 8 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 1,764 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

xcf-user-guide scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

XCF Xcode MCP Server - Comprehensive User Guide 🚀

🌟 Introduction

XCF (Xcode MCP Server) is a powerful, Swift-native automation tool designed to revolutionize your Xcode development workflow. This guide provides an in-depth look at installation, configuration, and usage of XCF.

🔧 Installation & Setup

System Requirements

  • macOS (latest version recommended)
  • Xcode installed
  • Basic understanding of terminal and Swift development

Installation Steps

  1. Download XCF

    • Visit the official website or GitHub repository
    • Download the latest XCF application
  2. Install Application

    • Drag the XCF.app to your /Applications folder
    • Launch the application once to approve internet downloads
  3. Codesign (if needed)

    codesign --force --deep --sign - /Applications/xcf.app
    

Configuration

MCP Server Configuration

Add XCF to your MCP configuration file:

{
  "mcpServers": {
    "xcf": {
      "type": "stdio",
      "command": "/Applications/xcf.app/Contents/MacOS/xcf server"
    }
  }
}
Configuration Locations
  • Cursor: ~/.cursor/mcp.json
  • Claude Desktop: ~/Library/Application Support/Claude/claude_desktop_config.json
Advanced Configuration

For project-specific control:

{
  "mcpServers": {
    "xcf": {
      "type": "stdio",
      "command": "/Applications/xcf.app/Contents/MacOS/xcf server",
      "env": {
          "XCODE_PROJECT_FOLDER": "/path/to/project/",
          "XCODE_PROJECT": "/path/to/project/project.xcodeproj"
      }
    }
  }
}

🎬 Getting Started

Activation

Activate XCF mode:

use_xcf

Basic Workflow

  1. List available projects

    show
    
  2. Select a project

    open 1  # Opens the first project in the list
    
  3. Build the project

    build
    
  4. Run the project

    run
    

📂 File Operations

Path Resolution and Quoting

XCF supports flexible path resolution:

  • Current directory: file.swift
  • Child directories: src/file.swift
  • Parent directory: ../file.swift
  • Multiple directories up: ../../file.swift
  • Full system paths: /Users/username/project/file.swift

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

xcf-user-guide is a cursor rule published in the GitHub repository CodeFreezeAI/xcf (12 stars, last pushed 5mo ago), licensed MIT. It adds 8 tokens to every session and 1,764 once invoked, about $0.0000 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
