TickTick MCP Server
A comprehensive Model Context Protocol (MCP) server for TickTick task management with 100% API coverage (112 operations).
🎉 BREAKTHROUGH: Task Cache System
NEW! Solves the major UX problem where users couldn't list their tasks. Now you can simply say:
- "Give me all tasks" ✅
- "List tasks from project X" ✅
- "Show my cached tasks" ✅
🚀 Cache Features
- Auto-Registration: New tasks automatically cached
- 24-Hour TTL: Fresh vs stale task detection
- CSV Import: Bootstrap with existing data
- Instant Discovery: No more 500 errors from bulk APIs
- Local Storage:
~/.ticktick-mcp-cache.json
# Now this works perfectly!
ticktick_get_cached_tasks() # List all cached tasks
ticktick_register_task_id() # Add existing tasks
ticktick_import_from_csv() # Bulk import
# All new tasks auto-cached ✨

📖 Usage Examples
🚀 NEW: Cache-Based Task Discovery
// 🎉 The breakthrough feature - list all your tasks!
await ticktick_get_cached_tasks();
// Returns: All cached tasks with fresh/stale status
// Register existing tasks for discovery
await ticktick_register_task_id({
task_id: "existing_task_123",
project_id: "project_456",
title: "My Existing Task"
});
// Import tasks from CSV export
await ticktick_import_from_csv({
csv_data: "task_id,project_id,title\ntask1,proj1,Design\ntask2,proj1,Development"
});
// Filter cached tasks by project
await ticktick_get_cached_tasks({ project_id: "specific_project" });
Task Management
// Create a new task (auto-cached! ✨)
await ticktick_create_task({
title: "Review Claude Code documentation",
project_id: "inbox",
priority: 3,
due_date: "2024-12-31"
});
// Task automatically appears in cache for easy discovery
// Get all projects
await ticktick_get_projects({ include_archived: false });
// Complete a task
await ticktick_complete_task({ task_id: "task123" });
Advanced Features
// Start a focus session
await ticktick_start_focus_session({
duration: 25, // Pomodoro: 25 minutes
task_id: "task123"
});
// Track habit completion
await ticktick_check_in_habit({
habit_id: "habit456",
date: "2024-01-15"
});
// Generate productivity report
await ticktick_get_productivity_report({
period: "week",
include_charts: true
});
🏗️ Architecture
Built on the Model Context Protocol (MCP) specification:
- Transport: stdio (standard input/output)
- Authentication: OAuth2 Bearer Token
- Error Handling: Comprehensive try-catch with user-friendly messages
- Response Format: Rich markdown with emojis and structured data
⚠️ Critical: TickTick API Sync Limitations
IMPORTANT: TickTick has hidden sync limitations that are not documented in their API. Our extensive testing revealed critical issues:
🚫 Characters That Break Sync
Tasks created with these characters will return API success (200) but WILL NOT appear in TickTick apps:
// ❌ THESE BREAK SYNC (avoid in task content):
"content": "Line 1\nLine 2" // Actual newlines
"content": "Path: C:\\Users\\folder" // Backslashes
"content": "Literal \\n in text" // Escape sequences
"content": "Quote: \"hello\"" // Escaped quotes in content
✅ Characters That Work Perfectly
// ✅ THESE ARE SAFE (work perfectly):
"content": "Emojis work: 💻🚀📊✅❌🔧🎯📁⚡🤖" // All emojis
"content": "Arrows: → ← ↑ ↓ ↗ ↖ ↘ ↙" // All arrows
"content": "Bullets: • ○ ■ ▪ ▫ ◦ ‣" // All bullets
"content": "Unicode: ñ é ü ç § ± © ® ™" // All Unicode
"content": "JSON: { } [ ] and arrays [1,2,3]" // JSON chars
"content": "Markdown: # header *bold* **strong**" // Markdown
"content": "Quotes work fine in content" // Regular quotes
🔧 Working Workflow Commands
Create Tasks (Safe Method)
# ✅ WORKING - Basic task creation
echo '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"ticktick_create_task","arguments":{"title":"My Task","content":"Safe content without newlines or backslashes","project_id":"your_project_id"}}}' | node src/index.js
# ✅ WORKING - With emojis and arrows
echo '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"ticktick_create_task","arguments":{"title":"💻 Coding Task","content":"Use arrows for workflow: Plan → Code → Test → Deploy 🚀","project_id":"your_project_id"}}}' | node src/index.js
Test Your Setup
# Test if your token works
echo '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"ticktick_get_projects","arguments":{}}}' | node src/index.js
# Create a test task (should appear in your TickTick app)
echo '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"ticktick_create_task","arguments":{"title":"API Test","content":"This task should appear in your TickTick app within seconds"}}}' | node src/index.js
✅ BREAKTHROUGH: Task Reading Now Works!
Major Update: Fixed task reading by using correct endpoint pattern!
Working Commands:
# Read specific task (requires both project_id and task_id)
echo '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"ticktick_get_task_details","arguments":{"project_id":"YOUR_PROJECT_ID","task_id":"YOUR_TASK_ID"}}}' | node src/index.js
# 🎯 CRITICAL: Read inbox tasks (special project ID discovered!)
echo '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"ticktick_get_task_details","arguments":{"project_id":"inbox125308274","task_id":"YOUR_TASK_ID"}}}' | node src/index.js
🔑 Key Discovery: Inbox has special project ID inbox125308274 - not visible in projects list but required for reading inbox tasks!
✅ API Status - FULLY WORKING!
- Task Creation: ✅ Works perfectly (with character limitations below)
- Task Reading: ✅ CONFIRMED WORKING - Fixed endpoint pattern working in production
- Project Listing: ✅ Works perfectly
- Task Management: ✅ Full CRUD operations now functional
- 🎉 Cache System: ✅ NEW! FULLY TESTED & WORKING - Complete task discovery solution

node validate-ticktick-mcp.js
# Test character compatibility (recommended before using)
echo '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"ticktick_create_task","arguments":{"title":"Compatibility Test","content":"Testing safe characters: emojis 💻, arrows →, unicode é, bullets •"}}}' | node src/index.js
Validation Results:
- ✅ Cache System: All features working (registration, persistence, auto-caching, CSV import)
- ✅ Task creation: Works perfectly with character limitations
- ✅ Task reading: CONFIRMED WORKING - Fixed endpoint pattern
- ✅ Project management: Fully functional
- ✅ Complex operations: Now fully operational with working task reading
