📦 Installation

Using uvx (Recommended)

cd rtm-mcp
uv sync

🚀 Quick Start

1. Get RTM API Credentials

RTM API keys are issued through a separate developer portal (not your account settings):

1. Go to RTM API Key Registration — you may need to log in first.
2. Click "Apply for an API Key".
3. Fill in the form — app name (e.g. "Claude MCP"), description, anything works.
4. After submitting, you'll see your API Key and Shared Secret — save both.

2. Run Setup

rtm-setup

This will:

• Prompt for your API credentials.
• Open your browser for authorization.
• Save the auth token to ~/.config/rtm-mcp/config.json.

3. Configure Claude Desktop

Add to ~/.config/claude/claude_desktop_config.json:

{
  "mcpServers": {
    "rtm": {
      "command": "uvx",
      "args": ["rtm-mcp"]
    }
  }
}

💻 Usage Examples

Basic Usage

Once configured, you can ask Claude to manage your tasks:

• "Show my tasks due today"
• "Add a task to buy groceries tomorrow, high priority"
• "Complete the grocery task"
• "What high priority tasks do I have?"
• "Move the meeting prep task to my Work list"
• "Add a note to the project task"

Advanced Usage

When adding tasks, use RTM's Smart Add syntax:

Example: "Review report ^friday !1 #work =1h *weekly"
