# Donetick MCP Server

A production-ready Model Context Protocol (MCP) server for [Donetick](https://donetick.com) chores management. Enables Claude and other MCP-compatible AI assistants to interact with your Donetick instance through a secure, rate-limited API.

## Breaking Changes in v2.0.0

**Important**: Version 2.0.0 introduces breaking changes to authentication. If you're upgrading from v1.x, please read the [Migration Guide](MIGRATION.md).

**What Changed**:
- Authentication now uses JWT with username/password (instead of API tokens)
- API endpoints switched from eAPI to Full API
- 9 previously non-functional features now work (frequency metadata, rolling schedules, multiple assignees, assignment strategies, nagging notifications, pre-due notifications, private chores, points, sub-tasks)
- Premium membership no longer required for advanced features

**Quick Migration**:
1. Replace `DONETICK_API_TOKEN` environment variable with `DONETICK_USERNAME` and `DONETICK_PASSWORD`
2. Update your `.env` file or Claude Desktop configuration
3. Restart the server

See the [Migration Guide](MIGRATION.md) for detailed instructions.

## Features

- **5 Core Tools**: List, get, create, complete, and delete chores
- **Full Chore Configuration**: All 26+ fields now working including frequency metadata, rolling schedules, multiple assignees, assignment strategies, notifications, labels, priority, points, sub-tasks, and more
- **JWT Authentication**: Automatic token management with transparent refresh
- **Smart Caching**: Intelligent caching for get_chore operations (60s TTL by default)
- **Rate Limiting**: Token bucket algorithm prevents API overload
- **Retry Logic**: Exponential backoff with jitter for resilient operations
- **Async/Await**: Non-blocking operations using httpx
- **Input Validation**: Pydantic field validators with sanitization
- **Security Hardened**: HTTPS enforcement, sanitized logging, secure error messages, JWT token security
- **Docker Support**: Containerized deployment with security best practices
- **Comprehensive Testing**: Unit and integration tests with pytest
- **Type Safety**: Pydantic models for request/response validation

## Quick Start

**Easiest installation (Claude Code CLI):**

```bash
claude mcp add donetick uvx donetick-mcp-server@latest
```

Then configure your Donetick credentials when prompted.

**Or install manually with uvx:**

```bash
# Install uv (one-time setup)
curl -LsSf https://astral.sh/uv/install.sh | sh

# Add to Claude Desktop config
# ~/.config/Claude/claude_desktop_config.json
{
  "mcpServers": {
    "donetick": {
      "command": "uvx",
      "args": ["--refresh", "donetick-mcp-server"],
      "env": {
        "DONETICK_BASE_URL": "https://your-instance.com",
        "DONETICK_USERNAME": "your_username",
        "DONETICK_PASSWORD": "your_password"
      }
    }
  }
}
```

**Benefits:**
- ✅ No installation required - runs directly from PyPI
- ✅ Auto-updates with `--refresh` flag
- ✅ Isolated environment - no conflicts
- ✅ Works on Windows, macOS, Linux

## Requirements

- Donetick instance (self-hosted or cloud)
- Donetick account credentials (username and password)
- **For uvx method:** `uv` installed (see Quick Start)
- **For other methods:** Python 3.11 or higher

## Installation

### Option 1: uvx (Recommended - No Installation Required)

See [Quick Start](#quick-start) above.

The `--refresh` flag ensures you always get the latest version when Claude Desktop restarts.

### Option 2: Docker

1. **Clone the repository**:
   ```bash
   git clone https://github.com/jason1365/donetick-mcp-server.git
   cd donetick-mcp-server
   ```

2. **Create `.env` file**:
   ```bash
   cp .env.example .env
   # Edit .env with your configuration
   ```

3. **Configure environment variables**:
   ```env
   DONETICK_BASE_URL=https://your-instance.com
   DONETICK_USERNAME=your_username
   DONETICK_PASSWORD=your_password
   LOG_LEVEL=INFO
   ```

4. **Build and run**:
   ```bash
   docker-compose build
   docker-compose up -d
   ```

### Option 3: pip install (For System Integration)

If you want to install globally or in a virtual environment:

```bash
# Install from PyPI
pip install donetick-mcp-server

# Or install for development
git clone https://github.com/jason1365/donetick-mcp-server.git
cd donetick-mcp-server
pip install -e .

# Run the server
donetick-mcp-server
# Or: python -m donetick_mcp.server
```

Then configure Claude Desktop to use the installed command:

```json
{
  "mcpServers": {
    "donetick": {
      "command": "donetick-mcp-server",
      "env": {
        "DONETICK_BASE_URL": "https://your-instance.com",
        "DONETICK_USERNAME": "your_username",
        "DONETICK_PASSWORD": "your_password"
      }
    }
  }
}
```

## Authentication

v2.0.0 uses JWT-based authentication with your Donetick credentials.

**What You Need**:
- Your Donetick username (same as web login)
- Your Donetick password (same as web login)

**How It Works**:
1. Server logs in with your credentials on startup
2. JWT token received and stored in memory
3. Token automatically refreshed before expiration
4. No manual token management required

**Security**:
- Credentials stored only in environment variables or `.env` file
- JWT tokens kept in memory only (never persisted to disk)
- Automatic token refresh prevents session expiration
- HTTPS required for all connections

## Claude Desktop Integration

**Easiest Method - Claude Code CLI:**

```bash
claude mcp add donetick uvx donetick-mcp-server@latest
```

**Or manually edit the configuration file:**

**macOS**: `~/Library/Application Support/Claude/claude_desktop_config.json`
**Windows**: `%APPDATA%\Claude\claude_desktop_config.json`
**Linux**: `~/.config/Claude/claude_desktop_config.json`

## Configuration

### Environment Variables

| Variable | Required | Default | Description |
|----------|----------|---------|-------------|
| `DONETICK_BASE_URL` | Yes | - | Your Donetick instance URL (must use HTTPS) |
| `DONETICK_USERNAME` | Yes | - | Your Donetick username |
| `DONETICK_PASSWORD` | Yes | - | Your Donetick password |
| `LOG_LEVEL` | No | INFO | Logging level (DEBUG, INFO, WARNING, ERROR) |
| `RATE_LIMIT_PER_SECOND` | No | 10.0 | Requests per second limit |
| `RATE_LIMIT_BURST` | No | 10 | Maximum burst size |

### Rate Limiting

The server implements a token bucket rate limiter to prevent API overload:

- **Default**: 10 requests per second with burst capacity of 10
- **Conservative**: Starts conservative and can be increased based on your Donetick instance
- **Respects 429**: Automatically backs off when rate limited by the API

### Retry Logic

- **Exponential backoff** with jitter for transient failures
- **Maximum 3 retries** for most operations
- **Smart retry**: Only retries on 5xx errors and 429 (rate limit)
- **No retry on 4xx**: Client errors fail immediately (except 429)

## API Documentation

This server uses the Donetick Full API with JWT authentication. Official documentation:
- **API Docs**: https://docs.donetick.com/
- **GitHub**: https://github.com/donetick/donetick

### Important Notes

1. **Authentication**: Uses JWT Bearer tokens (automatically managed)
2. **Full Feature Support**: All 26+ chore creation fields now working
3. **Automatic Token Refresh**: JWT tokens refreshed transparently
4. **Circle Scoped**: All operations are scoped to your circle (household/team)
5. **No Premium Required**: Advanced features work with standard accounts

## Troubleshooting

### Common Issues

**"DONETICK_BASE_URL environment variable is required"**
- Make sure your `.env` file exists and is properly formatted
- For Docker: ensure environment variables are passed in docker-compose.yml

**"Rate limited, waiting..."**
- The server is respecting API rate limits
- Consider reducing `RATE_LIMIT_PER_SECOND` if this happens frequently

**"Connection refused" or timeout errors**
- Verify your Donetick instance URL is correct
- Check that your Donetick instance is accessible
- Ensure firewall rules allow outbound connections

**"401 Unauthorized" or "Invalid credentials"**
- Verify your username and password are correct
- Check that your account is not locked or disabled
- Ensure you can login to Donetick web interface with the same credentials
- Check for typos in environment variables

**Tools not showing in Claude**
- Restart Claude Desktop after configuration changes
- Check Claude Desktop logs for errors
- Verify the configuration file path is correct

### Debugging

Enable debug logging:

```bash
export LOG_LEVEL=DEBUG
```

Or in Docker:

```yaml
environment:
  - LOG_LEVEL=DEBUG
```

View Docker logs:

```bash
docker-compose logs -f donetick-mcp
```

## Security

- **Credentials**: Never commit credentials to version control (use `.env` file)
- **JWT Tokens**: Stored in memory only, never persisted to disk
- **Automatic Token Refresh**: Prevents session expiration without user intervention
- **Docker Isolation**: Runs as non-root user in container
- **Resource Limits**: Memory and CPU limits prevent resource exhaustion
- **Input Validation**: Pydantic models validate all inputs
- **HTTPS Required**: Server enforces HTTPS for all Donetick connections
