  }
}

Option 3: Local development

{
  "mcpServers": {
    "worktree-tools": {
      "command": "node",
      "args": ["/Users/YOUR_USERNAME/worktree-tools-mcp/dist/index.js"]
    }
  }
}

After adding the configuration, restart Claude Code to enable the MCP server.

Usage Examples with Claude

Once configured, Claude can automatically manage worktrees:

Example 1: Create a new worktree

User: "Create a worktree for ticket CO-1234 called payment integration"
Claude: [calls create_worktree tool]
Claude: "I've created a new worktree at ~/repos/myproject-worktrees/username/CO-1234/payment-integration
        with dependencies installed and .env files copied. The worktree is ready to use."

Example 2: List all worktrees

User: "Show me all my active worktrees"
Claude: [calls list_worktrees tool]
Claude: "You have 3 active worktrees:
        1. CO-1234/payment-integration - 5 commits ahead, clean
        2. CO-5678/user-dashboard - 2 commits ahead, uncommitted changes
        3. CO-9012/api-refactor - up to date"

Example 3: Create PR from worktree

User: "Create a PR for my payment integration work"
Claude: [calls create_pr tool]
Claude: "I've created PR #123: 'Add payment integration'
        URL: https://github.com/org/repo/pull/123"

Example 4: Clean up worktree

User: "Clean up the payment integration worktree"
Claude: [calls cleanup_worktree tool with deleteBranch: true]
Claude: "I've removed the worktree and deleted the local branch."

Username Detection

Usernames are automatically detected with this priority:

1. Manual override - From .worktree-config file in repo root

2. GitHub CLI - Uses gh api user --jq .login

3. Git config - Converts user.name to username format (lowercase, hyphens)

If detection fails, you'll get a clear error message with instructions.

Directory Structure

Worktrees are organized as:

~/repos/
├── myproject/                        (main repository)
└── myproject-worktrees/              (all worktrees)
    └── username/
        ├── CO-1234/
        │   └── payment-integration/
        └── CO-5678/
            └── user-dashboard/

Development

# Install dependencies
npm install

# Run in development mode
npm run dev

# Build
npm run build

# Test the MCP server
npm run build && node dist/index.js

Companion Bash Scripts

This MCP server complements the worktree-tools bash scripts (located at ~/.checkout-scripts/ or ~/.worktree-tools/). You can use both:

• Bash scripts - For manual CLI usage

• MCP server - For Claude automation

Both implement the same logic and can be used interchangeably. The bash scripts provide a zero-dependency CLI interface, while the MCP server enables Claude to automate worktree operations.

Requirements

• Node.js 18+

• Git

• Optional: GitHub CLI (gh) for better username detection and PR creation

• Optional: pnpm, npm, or yarn for dependency installation
