# KeenMail MCP Server

A Model Context Protocol (MCP) server for integrating with the KeenMail API. This server allows AI assistants to send template-based emails through KeenMail's service.

## Features

- **MCP Compatible**: Works with Claude Desktop and other MCP clients
- **UVX Ready**: Installable and runnable via `uvx` for easy distribution
- **Environment Configuration**: Secure API key management through environment variables
- **STDIO Transport**: Full compatibility with MCP protocol standards
- **Template Email Sending**: Send emails using KeenMail templates with dynamic data

```bash
uvx keenmail-mcp-server
```

### Using Docker (Recommended for Production)

```bash
# Quick start with Docker Compose
git clone <repository-url>
cd keenmail-mcp-server
cp .env.docker .env

docker-compose up -d
```

### Using pip

```bash
pip install keenmail-mcp-server
```

### From source

```bash
git clone <repository-url>
cd keenmail-mcp-server

Set the following environment variables before running:

```bash
export KEENMAIL_API_KEY="your_api_key_here"
export KEENMAIL_SECRET="your_secret_key_here"
export KEENMAIL_BASE_URL="https://app.keenmail.com/api/v1"  # Optional, defaults to this
```

### Environment File (.env)

You can also create a `.env` file in your working directory:

```bash
KEENMAIL_API_KEY=your_api_key_here
KEENMAIL_SECRET=your_secret_key_here
```

## Usage

```json
{
  "mcpServers": {
    "keenmail": {
      "command": "uvx",
      "args": ["keenmail-mcp-server"],
      "env": {
        "KEENMAIL_API_KEY": "your_api_key",
        "KEENMAIL_SECRET": "your_secret"
      }
    }
  }
}
```

```

## Available Tools

The MCP server exposes the following tools:

### `sendTemplateEmail`

Send an email using a KeenMail template.

**Parameters:**
- `templateId` (string): The ID of the email template
- `providerId` (string): The email provider configuration ID
- `recipients` (array): List of recipient objects with email details and template data

**Example:**
```json
{
  "templateId": "welcome_email",
  "providerId": "ses_smtp_test",
  "recipients": [
    {
      "from": "sender@example.com",
      "to": "recipient@example.com",
      "data": {
        "userName": "John Doe",
        "companyName": "Example Corp"
      }
    }
  ]
}
```

## Development

### Requirements

- Python 3.10+
- uv (recommended) or pip

### Setup

```bash
# Clone the repository
git clone <repository-url>
cd keenmail-mcp-server

# Install dependencies with uv
uv sync --dev

# Or with pip
pip install -e ".[dev]"
```

### Running Tests

```bash
uv run pytest
```

### Linting and Formatting

```bash
# Run ruff linter
uv run ruff check .

# Format code
uv run ruff format .

# Type checking
uv run mypy src/
```

### Building

#### Python Package
```bash
uv build
```

#### Docker Image
```bash
# Quick build
./scripts/docker-build.sh

# Build with specific tag
./scripts/docker-build.sh --tag v0.1.0

# Multi-platform build and push
./scripts/docker-build.sh --platform linux/amd64,linux/arm64 --push --tag v0.1.0
```

## Publishing

This package uses automated publishing through GitHub Actions:

1. **Create a version tag:**
   ```bash
   # Update version in pyproject.toml first, then:
   uv version patch  # or minor, major
   git add .
   git commit -m "Bump version to $(uv version --dry-run patch)"
   git tag "v$(grep version pyproject.toml | cut -d'"' -f2)"
   git push origin main --tags
   ```

2. **Automatic publishing:** The GitHub Action will automatically build and publish to PyPI when a version tag is pushed.

### Manual Publishing

#### Python Package
```bash
# Build the package
uv build

# Publish to PyPI
uv publish
```

#### Docker Image
```bash
# Build and push to GitHub Container Registry
./scripts/docker-build.sh --push --tag v0.1.0

# Or manually with Docker
docker build -t ghcr.io/yourusername/keenmail-mcp-server:v0.1.0 .
docker push ghcr.io/yourusername/keenmail-mcp-server:v0.1.0
```

## Docker Deployment

### Quick Start

1. **Clone the repository:**
   ```bash
   git clone <repository-url>
   cd keenmail-mcp-server
   ```

2. **Set up environment:**
   ```bash
   cp .env.docker .env
   # Edit .env with your KeenMail API credentials
   ```

3. **Run with Docker Compose:**
   ```bash
   # Development
   docker-compose up -d
   
   # Production
   docker-compose -f docker-compose.prod.yml up -d
   ```

### Production Deployment

The production Docker setup includes:
- **Security hardening** with non-root user and read-only filesystem
- **Resource limits** and health checks
- **Log rotation** and structured logging
- **Restart policies** for high availability
- **Network isolation** with custom bridge network

```bash
# Production deployment
cp .env.docker .env
# Configure production credentials
docker-compose -f docker-compose.prod.yml up -d

# Monitor
docker-compose -f docker-compose.prod.yml ps
docker-compose -f docker-compose.prod.yml logs -f
```

### Container Registry

Images are automatically published to GitHub Container Registry:
- `ghcr.io/yourusername/keenmail-mcp-server:latest` - Latest development build
- `ghcr.io/yourusername/keenmail-mcp-server:v0.1.0` - Specific version tags
