Features

MCP Server

• 43 Tools: Streamlined coverage of TickTick functionality
• Batch Operations: All mutations accept lists (1-100 items) for bulk operations
• AI-Ready: Works with Claude, GPT, and other MCP-compatible assistants
• Dual Output: Markdown for humans, JSON for machines

Python Library

• Full Async Support: Built on httpx for high-performance async operations
• Batch Operations: Create, update, delete, complete up to 100 tasks in a single call
• Complete Task Management: Create, read, update, delete, complete, move, pin tasks
• Kanban Boards: Full column management (create, update, delete, move tasks between columns)
• Project Organization: Projects, folders, kanban boards
• Tag System: Hierarchical tags with colors
• Habit Tracking: Full CRUD for habits with batch check-ins, streaks, and goals
• Focus/Pomodoro: Access focus session data and statistics
• User Analytics: Productivity scores, levels, completion rates

Developer Experience

• Type-Safe: Full Pydantic v2 validation with comprehensive type hints
• Well-Tested: 300+ tests covering both mock and live API interactions
• Documented: Extensive docstrings and examples

Why This Library?

The Two-API Problem

TickTick has two different APIs:

The official V1 API is limited. Most of TickTick's power features (tags, habits, focus tracking) are only available through the undocumented V2 web API. This library combines both, routing each operation to the appropriate API automatically.

Compared to Other Libraries

Based on analysis of the actual source code of available TickTick Python libraries:

Key Differentiators:

• MCP Server: Only ticktick-sdk provides AI assistant integration via Model Context Protocol
• Unified API Routing: Automatically routes operations to V1 or V2 based on feature requirements
• Full Habit CRUD: Complete habit management including check-ins, streaks, archive/unarchive
• Async-First: Built on httpx for high-performance async operations

Installation

pip install ticktick-sdk

Requirements:

• Python 3.11+
• TickTick account (free or Pro)

MCP Server Setup & Usage

Use TickTick with AI assistants like Claude through the Model Context Protocol.

Step 1: Register Your App

1. Go to the TickTick Developer Portal
2. Click "Create App"
3. Fill in:
   • App Name: e.g., "My TickTick MCP"
   • Redirect URI: http://127.0.0.1:8080/callback
4. Save your Client ID and Client Secret

Step 2: Get OAuth2 Access Token

Run the auth command with your credentials:

TICKTICK_CLIENT_ID=your_client_id \
TICKTICK_CLIENT_SECRET=your_client_secret \
ticktick-sdk auth

This will:

1. Open your browser to TickTick's authorization page
2. Authorize the app - Click "Authorize" to grant access
3. Return to terminal - After authorizing, you'll see output like this:

============================================================
  SUCCESS! Here is your access token:
============================================================

a]234abc-5678-90de-f012-34567890abcd

============================================================

NEXT STEPS:

For Claude Code users:
  Run (replace YOUR_* placeholders):
    claude mcp add ticktick \
      -e TICKTICK_CLIENT_ID=YOUR_CLIENT_ID \
      ...

1. Copy this token - You'll need it in the next step

Note: Sometimes the browser shows an "invalid credentials" error page. Just refresh the page and it should work.

SSH/Headless Users: Add --manual flag for a text-based flow that doesn't require a browser.

Step 3: Configure Your AI Assistant

Claude Code (Recommended)

claude mcp add ticktick \
  -e TICKTICK_CLIENT_ID=your_client_id \
  -e TICKTICK_CLIENT_SECRET=your_client_secret \
  -e TICKTICK_ACCESS_TOKEN=your_access_token \
  -e TICKTICK_USERNAME=your_email \
  -e TICKTICK_PASSWORD=your_password \
  -- ticktick-sdk

Note: For TICKTICK_ACCESS_TOKEN, paste the token you copied from Step 2.

Verify it's working:

claude mcp list        # See all configured servers
/mcp                   # Within Claude Code, check server status

Claude Desktop

Add to your Claude Desktop config:

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

{
  "mcpServers": {
    "ticktick": {
      "command": "ticktick-sdk",
      "env": {
        "TICKTICK_CLIENT_ID": "your_client_id",
        "TICKTICK_CLIENT_SECRET": "your_client_secret",
        "TICKTICK_ACCESS_TOKEN": "your_access_token",
        "TICKTICK_USERNAME": "your_email",
        "TICKTICK_PASSWORD": "your_password"
      }
    }
  }
}

Other MCP-Compatible Tools

This server works with any tool that supports the Model Context Protocol, which includes most modern AI assistants and IDEs. The configuration is similar - you just need to provide the command (ticktick-sdk) and the environment variables shown above.

CLI Reference

The ticktick-sdk command provides several subcommands:

Tool Filtering (reduces context window usage for AI assistants):

# Enable only task and project tools
ticktick-sdk server --enabledModules tasks,projects

# Enable specific tools only
ticktick-sdk server --enabledTools ticktick_create_tasks,ticktick_list_tasks

# Available modules: tasks, projects, folders, columns, tags, habits, user, focus

Example Conversations

Once configured, you can ask Claude things like:

• "What tasks do I have due today?"
• "Create a task to call John tomorrow at 2pm"
• "Show me my high priority tasks"
• "Mark the grocery shopping task as complete"
• "What's my current streak for the Exercise habit?"
• "Check in my meditation habit for today"
• "Create a new habit to drink 8 glasses of water daily"
