# Or using pip
pip install vultr-dns-mcp
```
### Basic Usage
```bash
# CLI - requires VULTR_API_KEY environment variable
vultr-dns-mcp domains list
vultr-dns-mcp records list example.com
# As MCP server
uv run python -m vultr_dns_mcp.server --api-key YOUR_API_KEY
```
## Development Setup
### Dependencies
```bash
# Using uv (recommended)

# Testing Vultr DNS MCP in Claude Desktop
This guide shows how to set up and test the Vultr DNS MCP package locally with Claude Desktop.
## Prerequisites
1. **Claude Desktop** installed on your machine
2. **Vultr API Key** - Get from [Vultr Account > API](https://my.vultr.com/settings/#settingsapi)
3. **Python 3.10+** with the package installed
## Installation Options
### Option 1: Install from PyPI (Recommended)
```bash
pip install vultr-dns-mcp
```
### Option 2: Install from Local Development
```bash
# From this project directory
pip install -e .
```
### Option 3: Using uv (Fastest)
```bash
uv add vultr-dns-mcp
```
## Claude Desktop Configuration
### 1. Locate Claude Desktop Config
The configuration file location depends on your OS:
- **macOS**: `~/Library/Application Support/Claude/claude_desktop_config.json`
- **Windows**: `%APPDATA%/Claude/claude_desktop_config.json`
- **Linux**: `~/.config/Claude/claude_desktop_config.json`
### 2. Add MCP Server Configuration
Add this to your `claude_desktop_config.json`:
```json
{
"mcpServers": {
"vultr-dns": {
"command": "python",
"args": ["-m", "vultr_dns_mcp.server"],
"env": {
"VULTR_API_KEY": "YOUR_VULTR_API_KEY_HERE"
}
}
}
}
```
### 3. Alternative: Using uv (if you have it)
```json
{
"mcpServers": {
"vultr-dns": {
"command": "uv",
"args": ["run", "python", "-m", "vultr_dns_mcp.server"],
"env": {
"VULTR_API_KEY": "YOUR_VULTR_API_KEY_HERE"
}
}
}
}
```
### 4. Using Absolute Path (Most Reliable)
If you have issues, use the absolute path to your Python installation:
```json
{
"mcpServers": {
"vultr-dns": {
"command": "/usr/bin/python3",
"args": ["-m", "vultr_dns_mcp.server"],
"env": {
"VULTR_API_KEY": "YOUR_VULTR_API_KEY_HERE"
}
}
}
}
```
## Testing the Setup
### 1. Restart Claude Desktop
After saving the configuration file, completely restart Claude Desktop.
### 2. Test MCP Connection
In Claude Desktop, you should see:
- An indicator that the MCP server is connected
- Access to Vultr DNS tools in the interface
### 3. Example Prompts to Try
Once connected, try these prompts in Claude Desktop:
```
"List all my DNS domains"
```
```
"Show me the DNS records for example.com"
```
```
"Create an A record for www.example.com pointing to 192.168.1.100"
```
```
"Analyze the DNS configuration for my domain and suggest improvements"
```
```
"Set up basic website DNS for newdomain.com with IP 203.0.113.10"
```
## Available MCP Tools
The server provides these tools that Claude Desktop can use:
1. **list_dns_domains** - List all your DNS domains
2. **get_dns_domain** - Get details for a specific domain
3. **create_dns_domain** - Create a new DNS domain
4. **delete_dns_domain** - Delete a domain and all its records
5. **list_dns_records** - List DNS records for a domain
6. **get_dns_record** - Get details for a specific record
7. **create_dns_record** - Create a new DNS record
8. **update_dns_record** - Update an existing record
9. **delete_dns_record** - Delete a DNS record
10. **validate_dns_record** - Validate a record before creation
11. **analyze_dns_records** - Analyze domain DNS configuration
12. **setup_website_dns** - Quick setup for website DNS
## Troubleshooting
### MCP Server Won't Start
1. **Check Python installation**:
```bash
python -c "import vultr_dns_mcp; print('✅ Package installed')"
```
2. **Test server manually**:
```bash
export VULTR_API_KEY="your-key"
python -m vultr_dns_mcp.server
```
3. **Check API key**:
```bash
export VULTR_API_KEY="your-key"
python -c "
from vultr_dns_mcp.client import VultrDNSClient
import asyncio
async def test():
client = VultrDNSClient()
domains = await client.domains()
print(f'✅ Found {len(domains)} domains')
asyncio.run(test())
"
```
### Path Issues
If Claude Desktop can't find Python:
1. **Find your Python path**:
```bash
which python3
# or
which python
```
2. **Update config with full path**:
```json
{
"mcpServers": {
"vultr-dns": {
"command": "/full/path/to/python3",
"args": ["-m", "vultr_dns_mcp.server"],
"env": {
"VULTR_API_KEY": "YOUR_KEY"
}
}
}
}
```
### Virtual Environment Issues
If using a virtual environment:
1. **Activate and find Python**:
```bash
source your-venv/bin/activate # or your-venv\Scripts\activate on Windows
which python
```
2. **Use that path in config**:
```json
{
"mcpServers": {
"vultr-dns": {
"command": "/path/to/your-venv/bin/python",
"args": ["-m", "vultr_dns_mcp.server"],
"env": {
"VULTR_API_KEY": "YOUR_KEY"
}
}
}
}
```
## Security Notes
- Keep your Vultr API key secure
- Consider using environment variables instead of hardcoding in config
- The API key has access to modify your DNS records
## Example Natural Language Interactions
Once set up, you can use natural language with Claude Desktop:
- "What domains do I have in Vultr?"
- "Add a CNAME record for blog.example.com pointing to example.com"
- "Delete the old MX record for example.com"
- "Set up email DNS for my domain with mail.example.com as the mail server"
- "Check if my domain has proper SPF and DMARC records"
- "Create an IPv6 AAAA record for www pointing to 2001:db8::1"
Claude Desktop will use the MCP tools to perform these operations on your behalf!
## Next Steps
- Try the natural language prompts above
- Explore the comprehensive DNS management capabilities
- Use the analysis features to improve your DNS setup
- Set up automation for common DNS tasks
Happy DNS managing! 🎉

## 🔧 Key Technical Fixes ## Testing
### 1. Fixed Async Patterns This project follows FastMCP testing best practices with comprehensive test coverage:
- Proper `@pytest.mark.asyncio` usage
- Correct `async with Client(server) as client:` context managers
- Fixed await patterns throughout
### 2. Improved Mock Configuration ```bash
- Complete `AsyncMock` setup with proper specs # Run all tests (uv)
- All Vultr API methods properly mocked uv run pytest
- Realistic API response structures
### 3. Better Error Handling # Run specific test categories
- Comprehensive error scenario testing uv run pytest -m unit # Unit tests
- Graceful handling of API failures uv run pytest -m integration # Integration tests
- Proper exception testing patterns uv run pytest -m mcp # MCP-specific tests
### 4. Updated Dependencies # With coverage
- Fixed pytest-asyncio configuration uv run pytest --cov=vultr_dns_mcp --cov-report=html
- Proper FastMCP version requirements
- Added missing test dependencies
## 🆘 Troubleshooting # Full validation suite
uv run python run_tests.py --all-checks
```
### If tests still fail: ## Contributing
1. **Check installation**: 1. Fork the repository
```bash 2. Create a feature branch (`git checkout -b feature/amazing-feature`)
pip list | grep -E "(pytest|fastmcp|httpx)" 3. Make your changes
``` 4. Run the test suite (`uv run python run_tests.py --all-checks`)
5. Commit your changes (`git commit -m 'Add amazing feature'`)
6. Push to the branch (`git push origin feature/amazing-feature`)
7. Open a Pull Request
2. **Verify imports**: ## Error Handling
```bash
python -c "from vultr_dns_mcp.server import create_mcp_server"
```
3. **Run single test**: The package provides specific exception types for better error handling:
```bash
pytest tests/test_mcp_server.py::TestMCPTools::test_list_dns_domains_tool -vvv
```
4. **Check pytest config**: ```python
```bash from vultr_dns_mcp import (
pytest --collect-only tests/ VultrAPIError,
``` VultrAuthError,
VultrRateLimitError,
VultrResourceNotFoundError,
VultrValidationError
)
### Common Issues: try:
- **ImportError**: Run `pip install -e .` from repository root await client.get_domain("example.com")
- **AsyncioError**: Ensure `asyncio_mode = "auto"` in pyproject.toml except VultrAuthError:
- **MockError**: Check that fixed_conftest.py was properly copied print("Invalid API key or insufficient permissions")
except VultrResourceNotFoundError:
print("Domain not found")
except VultrRateLimitError:
print("Rate limit exceeded, please try again later")
except VultrAPIError as e:
print(f"API error {e.status_code}: {e.message}")
```
## 📊 Success Metrics ## Configuration

```bash ```bash
# Comprehensive test runner # Comprehensive test runner (uv)
python run_tests.py uv run python run_tests.py

python run_tests.py --type unit --verbose uv run python run_tests.py --type unit --verbose

python run_tests.py --fast # Skip slow tests uv run python run_tests.py --fast # Skip slow tests
# Full validation # Full validation
uv run python run_tests.py --all-checks

### Traditional approach (fallback):
```bash
# All tests
pytest
# Test runner
python run_tests.py --all-checks python run_tests.py --all-checks
