Usage with Claude Desktop

Add to your Claude Desktop config file (~/Library/Application Support/Claude/claude_desktop_config.json):

{
  "mcpServers": {
    "bike": {
      "command": "node",
      "args": ["/path/to/bike-mcp-server/dist/index.js"]
    }

}

Then restart Claude Desktop.

Development

# Watch mode for development
npm run dev

# Build
npm run build

# Run directly
npm start

How It Works

The server communicates with Bike via AppleScript, using the osascript command. All operations require Bike to be running with a document open.

The outline structure is returned as human-readable indented text:

My Document (doc:abc123)

- First item [row:row-1]
  - Sub-item [row:row-1-1]
- Second item [row:row-2]

Example Prompts

Here are some prompts you can use with Claude Desktop:

1. Explore your outlines: "List my open Bike documents and show me the outline of the first one"

2. Create structured content: "Create a new Bike document with a project plan that has 3 main phases, each with 2-3 tasks"

3. Search and transform: "Find all rows containing 'TODO' in my Bike document and convert them to task items"

Testing

No account or authentication required. To test the server:

1. Open Bike app on macOS
2. Create or open a document with some sample content
3. Use Claude Desktop to interact with your outlines

Privacy

This server does not collect, store, or transmit any personal data. All communication happens locally between Claude Desktop and the Bike app via AppleScript. No data leaves your machine.
