xcf

🚀 XCF Xcode MCP Server

The Swift way to Super Charge your AI Workflow!

🚧 New features are in development...

• File Operations
• Directory Operations
• Scripting Bridge Xcode Doc Operations
• AI Coding Diff Tools (In the works!)
• ✅ Fuzzy Logic
• ✅ Swift code analysis without building in Xcode

Speed up writing Xcode apps with xcf, a dead simple Swift-based MCP server specifically designed for Cursor. Works seamlessly with VSCode and Claude, with no TypeScript, no JavaScript, no BS!

🧰 XCF Installation & Configuration

Installation Steps

1. Download the XCF application and drag it to your /Applications folder.
2. Launch the application to approve the internet download.

4. You will see the following alert (this is expected):

6. Click the "Press to Quit this XCF Xcode MCP Server" button.

💡 Troubleshooting: If XCF doesn't display the alert, run this command:

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

You can also build xcf from source using Xcode. It's 100% Swift and easy to build locally.

🔧 Quick Setup

Minimum Requirements:

Add xcf to your MCP configuration file:

{
  "mcpServers": {
    "xcf": {
      "type": "stdio",
      "command": "Applications/xcf.app/Contents/MacOS/xcf",
      "args": ["server"]
    }
  }
}          

Configuration Locations

• Cursor: ~/.cursor/mcp.json
• Claude Desktop: ~/Library/Application Support/Claude/claude_desktop_config.json

⚠️ Important: Restart your AI assistant after setup or refresh the tool.

⚙️ Advanced Configuration

For non-Cursor clients or users requiring strict project-level control:

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

These environment variables let you:

• Pre-select a specific Xcode project to work with
• Define a custom workspace boundary for security

✨ Key Features

• Zero Dependencies: Easy to install, no reliance on other MCP servers
• Automatic Project Detection: Auto-selects your Xcode project so you can start coding immediately
• Real-time Error Handling: xcf build or xcf run sends errors and warnings from Xcode directly to your AI IDE
• AI-Powered Fixes: Let Claude fix bugs and mistakes during your coding sessions
• Intuitive Commands: Simple, developer-friendly command structure for maximum productivity
• Comprehensive File Operations: Read, write, edit, and delete files with ease
• Directory Management: Navigate, list, create, and remove directories
• Xcode Document Integration: Open, create, read, save, edit, and close Xcode documents directly
• Advanced Code Analysis: Get detailed Swift code analysis without building in Xcode

🛠️ Perfect for Swift Developers

The tool is designed by Swift developers, for Swift developers. Commands like build, run, show, and our new file and directory operations make the workflow intuitive and natural.

📄 Using Snippets

For Human Commands

xcf supports simplified, user-friendly snippet commands:

To get an entire file, just use the filename:

xcf snippet filename.swift

No need for full paths in many cases - xcf will intelligently find and display the complete file contents.

For specific line ranges:

xcf snippet filename.swift 10 20

You can use either format for file operations:

xcf snippet /path/to/file.swift                 // Direct path
xcf snippet filePath=/path/to/file.swift        // Named parameter

xcf analyze /path/to/file.swift                 // Direct path
xcf analyze filePath=/path/to/file.swift        // Named parameter

xcf lz /path/to/file.swift                      // Direct path (shorthand)
xcf lz filePath=/path/to/file.swift             // Named parameter (shorthand)

For specific line ranges:

xcf snippet /path/to/file.swift 10 20           // Direct path with line range
xcf snippet filePath=/path/to/file.swift startLine=10 endLine=20  // Named parameters

For AI Assistants

When using xcf through MCP tools, use this syntax:

mcp_xcf_snippet filePath="filename.swift" entireFile=true

For specific line ranges:

mcp_xcf_snippet filePath="filename.swift" startLine=10 endLine=20

Smart Path Resolution

When a file isn't found at the exact path, xcf will intelligently search for it in:

1. First tries the exact path provided
2. Resolves relative paths using the current working directory
3. Searches in the current project directory and one level up
4. Searches in the workspace folder defined by WORKSPACE_FOLDER_PATHS
5. Searches recursively in workspace folders with limited depth
6. As a last resort, performs a fuzzy search for similar filenames

This smart path resolution is used consistently across ALL file operations in xcf, including:

• File reading and writing
• Code snippets and analysis
• Directory operations
• File editing and deletion
• Document operations in Xcode

This means you can usually just use the filename without any path for any operation:

xcf snippet Constants.swift    // For humans
xcf analyze Constants.swift    // For humans
xcf edit Constants.swift       // For humans

Or for AI assistants:

mcp_xcf_snippet filePath="Constants.swift" entireFile=true
mcp_xcf_analyzer filePath="Constants.swift" entireFile=true
mcp_xcf_xcf action="edit Constants.swift"

🔍 Swift Code Analysis

For Human Commands

Analyze an entire Swift file for potential issues:

xcf analyze filename.swift

Or use the shorthand version:

xcf lz filename.swift

For specific line ranges:

xcf analyze filename.swift --startLine 10 --endLine 50

For AI Assistants

When using xcf through MCP tools, use this syntax:

mcp_xcf_analyzer filePath="filename.swift" entireFile=true

Or use the shorthand version:

mcp_xcf_xcf action="lz filename.swift"

For specific line ranges:

mcp_xcf_analyzer filePath="filename.swift" startLine=10 endLine=50

The analysis identifies issues like:

• Code style and formatting problems
• Functions with high complexity
• Unused variables and symbols
• Magic numbers
• Long methods
• And more
