await ticktick_create_task({
  title: "Review Claude Code documentation",
  project_id: "inbox",
  priority: 3,
  due_date: "2024-12-31"

🏗️ 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

🚨 Known API Issues

Read Operations: All GET endpoints return 500 "unknown_exception" errors
Task Creation: Works but only for specific character sets
Project Listing: Works perfectly
Task Deletion: Returns 500 errors (same as read operations)

See GitHub Issue #1 for detailed analysis.

🧪 Validation & Testing

# Test basic functionality
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:

✅ Task creation: Works with character limitations
❌ Task reading: API limitation (500 errors)
✅ Project management: Fully functional
⚠️ Complex operations: Limited by read operation failures
