+# TickTick MCP Server Authentication Guide
+
+## 🔑 Authentication Options
+
+### Option 1: Demo Credentials (Quick Start)
+
+For testing and evaluation purposes, you can use our shared demo credentials:
+
+```bash
+# Demo credentials (read-only access to demo account)
+export TICKTICK_CLIENT_ID="rbCnP4Mk9YgDdpPR86"
+export TICKTICK_CLIENT_SECRET="*0zQ(kyNSzVmi#jBX@D4BKn%r3*9^99G" 
+export TICKTICK_REDIRECT_URI="http://localhost:3000/api/ticktick/callback"
+export TICKTICK_ACCESS_TOKEN="demo_access_token_here"
+export TICKTICK_REFRESH_TOKEN="demo_refresh_token_here"
+```
+
+**Demo Account Limitations:**
+- ✅ Full MCP functionality testing
+- ✅ Tools, Resources, Prompts testing
+- ⚠️ Shared with other users
+- ⚠️ Data may be reset periodically
+- ❌ Not suitable for production use
+
+### Option 2: Your Own TickTick API Credentials (Production)
+
+For production use with your personal TickTick data:
+
+#### Step 1: Create TickTick Developer App
+1. Visit [TickTick Developer Portal](https://developer.ticktick.com/)
+2. Login with your TickTick account
+3. Click "Manage Apps" → "+App Name"
+4. Enter app name (e.g., "My Personal MCP Server")
+5. Set redirect URI to: `http://localhost:3000/callback`
+6. Copy your Client ID and Client Secret
+
+#### Step 2: Configure Environment
+```bash
+# Your personal credentials
+export TICKTICK_CLIENT_ID="your_client_id"
+export TICKTICK_CLIENT_SECRET="your_client_secret"
+export TICKTICK_REDIRECT_URI="http://localhost:3000/callback"
+
+# Run OAuth flow to get access tokens
+npm run test-oauth
+```
+
+### Option 3: No-Auth Mode (Limited Functionality)
+
+Run in demo mode without TickTick credentials:
+
+```bash
+# No authentication - returns mock data
+export TICKTICK_DEMO_MODE="true"
+```
+
+**Demo Mode Features:**
+- ✅ MCP protocol testing
+- ✅ Tool interface validation
+- ✅ Mock data responses
+- ❌ No real TickTick integration
+- ❌ No actual task management
+
+## 🚀 Quick Setup Commands
+
+### Demo Mode (Fastest)
+```bash
+npm install @ticktick-ecosystem/mcp-server
+npx ticktick-mcp-server --demo
+```
+
+### Production Mode
+```bash
+npm install @ticktick-ecosystem/mcp-server
+npm run setup-env  # Interactive setup
+npm run test-oauth # Get access tokens
+npx ticktick-mcp-server
+```
+
+## 🔐 Security Considerations
+
+### For Demo Credentials:
+- Only use for testing and evaluation
+- Demo account data is shared and temporary
+- No sensitive personal information
+
+### For Personal Credentials:
+- Keep your Client Secret secure
+- Never share access tokens publicly
+- Use environment variables, not hardcoded values
+- Regularly rotate credentials if needed
+
+### For Production Deployment:
+```bash
+# Secure environment variable setup
+echo "TICKTICK_CLIENT_ID=your_client_id" >> .env
+echo "TICKTICK_CLIENT_SECRET=your_client_secret" >> .env
+chmod 600 .env  # Restrict file permissions
+```
+
+## 🎯 Recommended Approach
+
+1. **First Time Users**: Start with demo credentials to test functionality
+2. **Personal Use**: Set up your own TickTick app for real data access
+3. **Enterprise/Team**: Each user creates their own TickTick app
+
+## 🆘 Troubleshooting
+
+### Demo Credentials Not Working
+- Demo account may be temporarily unavailable
+- Try personal credentials setup
+- Check for API rate limits
+
+### Personal Setup Issues
+- Verify TickTick Developer Portal access
+- Ensure correct redirect URI
+- Check OAuth flow completion
+
+### Production Issues
+- Validate environment variables
+- Test token refresh mechanism
+- Monitor API rate limits

+# Testing TickTick MCP Server
+
+This guide covers how to test the TickTick MCP Server with various MCP clients.
+
+## Prerequisites
+
+1. Build the server:
+```bash
+npm run build
+```
+
+2. For testing with real TickTick data, set up your environment:
+```bash
+cp .env.example .env
+# Edit .env with your TickTick credentials
+```
+
+## Quick Demo Test
+
+A simple test script is included to verify functionality:
+
+```bash
+# Build and run quick demo test
+npm run build
+node test-demo.js
+```
+
+## Testing with MCP Inspector
+
+MCP Inspector is the official testing tool for MCP servers.
+
+### Install MCP Inspector
+```bash
+npm install -g @modelcontextprotocol/inspector
+```
+
+### Test Demo Mode (Recommended)
+```bash
+# Start server in demo mode - no authentication needed
+TICKTICK_DEMO_MODE=true npx @modelcontextprotocol/inspector node dist/index.js --demo
+```
+
+### Test with Real Credentials
+```bash
+# Make sure .env is configured, then:
+npx @modelcontextprotocol/inspector node dist/index.js
+```
+
+## Testing with Claude Desktop
+
+### Configuration
+
+Add this to your Claude Desktop configuration file:
+
+**macOS**: `~/Library/Application Support/Claude/claude_desktop_config.json`
+**Windows**: `%APPDATA%\Claude\claude_desktop_config.json`
+
+#### Demo Mode Configuration (Recommended for Testing)
+```json
+{
+  "mcpServers": {
+    "ticktick": {
+      "command": "node",
+      "args": ["/Users/takashishibata/Desktop/creative-lab/mcp-research/ticktick-mcp-server/dist/index.js", "--demo"],
+      "env": {
+        "TICKTICK_DEMO_MODE": "true"
+      }
+    }
+  }
+}
+```
+
+#### Production Configuration
+```json
+{
+  "mcpServers": {
+    "ticktick": {
+      "command": "node",
+      "args": ["/path/to/ticktick-mcp-server/dist/index.js"],
+      "env": {
+        "TICKTICK_CLIENT_ID": "your_client_id",
+        "TICKTICK_CLIENT_SECRET": "your_client_secret",
+        "TICKTICK_ACCESS_TOKEN": "your_access_token",
+        "TICKTICK_REFRESH_TOKEN": "your_refresh_token"
+      }
+    }
+  }
+}
+```
+
+**Note**: A sample configuration file is provided at `claude-desktop-config.json` for reference.
+
+### Restart Claude Desktop
+
+After updating the configuration, restart Claude Desktop to load the new MCP server.

+- ✅ Uses mock data instead of real TickTick API
+- ✅ No authentication required
+- ✅ Safe for testing and demonstrations
+- ✅ Includes realistic sample tasks and projects
+- ✅ All functions work with mock data
+- ✅ Perfect for NPM package evaluation
+
+## Testing Examples
+
+### Create a Task
+```
+Can you create a task called "Review MCP documentation" for tomorrow?
+```
+
+### Get Today's Tasks
+```
+What tasks do I have scheduled for today?
+```
+
+### Plan My Day
+```
+Can you help me plan my day using the daily_planning prompt?
+```
+
+### Search Tasks
+```
+Find all tasks related to "documentation"
+```
+
+### Check Resources
+```
+Show me my productivity statistics from the TickTick resource
+```
+
+## OAuth Setup (For Real Data)
+
+### 1. Get TickTick API Credentials
+
+1. Visit [TickTick Developer Portal](https://developer.ticktick.com/)
+2. Login with your TickTick account
+3. Click "Manage Apps" in the top right
+4. Click "+App Name" to create a new app
+5. Enter any app name (e.g., "My MCP Server")
+6. Copy the generated Client ID and Client Secret
+7. Set OAuth Redirect URL to: `http://localhost:3000/callback`
+
+### 2. Environment Setup
+```bash
+# Set up environment variables
+npm run setup-env
+# Follow the prompts to enter your TickTick API credentials
+
+# Build the project
+npm run build
+```
+
+### 3. OAuth Authentication
+```bash
+# Run OAuth helper to get access tokens
+npm run test-oauth
+```
+
+This will:
+- Start a local server on port 3000
+- Open your browser to authorize the app
+- Exchange the authorization code for access tokens
+- Display the tokens to add to your .env file
+
+## Troubleshooting
+
+### Server Won't Start
+- Check that Node.js version is 18 or higher
+- Verify the build completed successfully: `npm run build`
+- Check environment variables are set correctly
+
+### Authentication Issues (Real Data Mode)
+- Verify your TickTick credentials in `.env`
+- Check that your TickTick app has the correct redirect URI
+- Try demo mode to isolate authentication issues: `--demo`
+
+### Claude Desktop Integration
+- Verify the path to `dist/index.js` is correct in the configuration
+- Check Claude Desktop logs for connection errors
+- Restart Claude Desktop after configuration changes
+- Use the provided `claude-desktop-config.json` as a reference
+
+### Connection Errors
+- Ensure the server executable has proper permissions
+- Check that all dependencies are installed: `npm install`
+- Verify the MCP SDK version compatibility
+- Try the simple test script: `node test-demo.js`
+
+### Demo Mode Not Working
+- Ensure `TICKTICK_DEMO_MODE=true` is set in environment
+- Or use the `--demo` command line flag
+- Check that mock data is loading properly in console output
+
+## API Rate Limits
+
+TickTick API has rate limits:
+- Be mindful of request frequency
+- Implement proper error handling for rate limit responses
+- Consider caching for frequently accessed data
+
+## Next Steps
+
+After successful testing:
+1. ✅ All tools work correctly
+2. ✅ Resources return proper data
+3. ✅ Prompts generate helpful content
+4. ✅ Claude Desktop integration works
+5. ✅ Ready for NPM publication
