Set up XcodeBuild MCP in Claude Code

Build, test, and deploy iOS and macOS apps from your AI editor. Full Xcode project control with simulator management, UI automation, and debugging.

Locate the config file

Claude Code reads MCP server configuration from the following file:

~/.claude.json

Create this file if it does not already exist.

You can configure XcodeBuild MCP using the CLI command or by editing the config file directly.

Option A: CLI command

bash

claude mcp add xcodebuild-mcp -- npx -y xcodebuildmcp

Option B: Config file

json

{
  "mcpServers": {
    "xcodebuild-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "xcodebuildmcp"
      ]
    }
  }
}

No environment variables needed. XcodeBuild MCP works out of the box without any API keys or tokens.

Restart Claude Code. XcodeBuild MCP should appear in your MCP server list with 76 tools available.

This server adds approximately 39,140 tokens to your context window for tool definitions.
