MCP server for accessing Apple's hidden Xcode documentation

Apple Deep Docs MCP

Access hidden Xcode documentation and Apple developer resources through the Model Context Protocol.

Overview

Modern Apple documentation uses the DocC rendering system which requires JavaScript to dynamically load content, making it inaccessible to some LLMs. This MCP server circumvents that limitation by providing comprehensive access to Apple's development documentation ecosystem, including:

• Hidden Xcode Documentation: Searches the AdditionalDocumentation folder inside Xcode.app containing advanced SwiftUI patterns, Liquid Glass design guides for iOS 26+, and framework-specific implementation details not available on Apple's public developer site
• Apple Developer API: Fetches and parses structured documentation from developer.apple.com
• Swift Evolution Proposals: Searches 500+ proposals to understand the "why" behind language features
• Swift Open Source Repositories: Searches across all Apple/SwiftLang GitHub repositories for implementation examples
• WWDC Session Notes: Accesses community-curated WWDC session summaries for performance optimization and architecture patterns
• Human Interface Guidelines: Searches through the Human Interface Guidelines

Requirements

• Python 3.10+
• Xcode installed (for local documentation features)

Installation

1. Clone this repository:

git clone https://github.com/Ahrentlov/appledeepdoc-mcp.git
cd appledeepdoc-mcp

2. Set up the Python environment:

# Create virtual environment
python3 -m venv venv

# Install dependencies
./venv/bin/pip install fastmcp

Configuration

Claude Code

For Claude Code, you need to add the MCP server using the following CLI commands:

Make sure run.sh is executable

chmod +x /path/to/appledeepdoc-mcp/run.sh

Add the MCP server to the local Claude Code project config

Navigate to the project folder where you will be activating Claude Code, then run the following command to register the MCP server:

claude mcp add --transport stdio apple-deep-docs /path/to/appledeepdoc-mcp/run.sh

Verify it was added

claude mcp list

Now when you activate claude in this folder, it will have the MCP server available.

Claude Desktop

Add to your Claude Desktop config file:

{
  "mcpServers": {
    "apple-deep-docs": {
      "command": "/path/to/appledeepdoc-mcp/run.sh"
    }
  }
}

GPT-Codex

Add to ~/.codex/config.toml:

[mcp_servers.apple-deep-docs]
"command" = "/path/to/appledeepdoc-mcp/run.sh"

Replace /path/to/appledeepdoc-mcp with the full path where you cloned this repository. The run.sh script automatically handles the virtual environment.

Config file locations:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

After updating the config, restart Claude Desktop to load the MCP server.
