# Vultr DNS MCP # Vultr DNS MCP Test Suite - Complete Fix Package
[![PyPI version](https://badge.fury.io/py/vultr-dns-mcp.svg)](https://badge.fury.io/py/vultr-dns-mcp) ## 🎯 Quick Solution
[![Python Support](https://img.shields.io/pypi/pyversions/vultr-dns-mcp.svg)](https://pypi.org/project/vultr-dns-mcp/)
[![License: MIT](https://img.shields.io/badge/License-MIT-yellow.svg)](https://opensource.org/licenses/MIT)
A comprehensive **Model Context Protocol (MCP) server** for managing Vultr DNS records. This package provides both an MCP server for AI assistants and a Python client library for direct DNS management. I've analyzed the broken tests in the vultr-dns-mcp repository and created a complete fix package. Here's how to apply it:
## 🚀 Features
- **Complete DNS Management** - Manage domains and all record types (A, AAAA, CNAME, MX, TXT, NS, SRV)
- **MCP Server** - Full Model Context Protocol server for AI assistant integration
- **Python Client** - Direct Python API for DNS operations
- **CLI Tool** - Command-line interface for DNS management
- **Smart Validation** - Built-in DNS record validation and best practices
- **Configuration Analysis** - Analyze DNS setup with recommendations
- **Natural Language Interface** - Understand complex DNS requests through MCP
## 📦 Installation
Install from PyPI:
### One-Command Fix (if you have access to this directory):
```bash ```bash
pip install vultr-dns-mcp # From your vultr-dns-mcp repository root:
bash /home/rpm/claude/vultr-dns-mcp-fix/fix_tests.sh
``` ```
Or install with development dependencies: ### Manual Fix (recommended):
```bash ```bash
pip install vultr-dns-mcp[dev] # 1. Navigate to your repository
``` cd /path/to/vultr-dns-mcp
## 🔑 Setup # 2. Backup current files
cp tests/conftest.py tests/conftest.py.backup
cp tests/test_mcp_server.py tests/test_mcp_server.py.backup
Get your Vultr API key from the [Vultr Control Panel](https://my.vultr.com/settings/#settingsapi). # 3. Copy fixed files
cp /home/rpm/claude/vultr-dns-mcp-fix/fixed_conftest.py tests/conftest.py
cp /home/rpm/claude/vultr-dns-mcp-fix/fixed_test_mcp_server.py tests/test_mcp_server.py
Set your API key as an environment variable: # 4. Install dependencies
```bash
export VULTR_API_KEY="your_vultr_api_key_here"
```
## 🖥️ Usage
### MCP Server
Start the MCP server for AI assistant integration:
```bash
vultr-dns-mcp server
```
Or use the Python API:
```python
from vultr_dns_mcp import run_server
run_server("your-api-key")
```
### Python Client
Use the client library directly in your Python code:
```python
import asyncio
from vultr_dns_mcp import VultrDNSClient
async def main():
client = VultrDNSClient("your-api-key")
# List all domains
domains = await client.domains()
print(f"Found {len(domains)} domains")
# Get domain info
summary = await client.get_domain_summary("example.com")
# Add DNS records
await client.add_a_record("example.com", "www", "192.168.1.100")
await client.add_mx_record("example.com", "@", "mail.example.com", priority=10)
# Set up basic website
await client.setup_basic_website("newdomain.com", "203.0.113.1")
asyncio.run(main())
```
### Command Line Interface
The package includes a comprehensive CLI:
```bash
# List domains
vultr-dns-mcp domains list
# Get domain information
vultr-dns-mcp domains info example.com
# Create a new domain
vultr-dns-mcp domains create example.com 192.168.1.100
# List DNS records
vultr-dns-mcp records list example.com
# Add DNS records
vultr-dns-mcp records add example.com A www 192.168.1.100
vultr-dns-mcp records add example.com MX @ mail.example.com --priority 10
# Set up a website
vultr-dns-mcp setup-website example.com 192.168.1.100
# Set up email
vultr-dns-mcp setup-email example.com mail.example.com
```
## 🤖 MCP Integration
### Claude Desktop
Add to your `~/.config/claude/mcp.json`:
```json
{
"mcpServers": {
"vultr-dns": {
"command": "vultr-dns-mcp",
"args": ["server"],
"env": {
"VULTR_API_KEY": "your_vultr_api_key_here"
}
}
}
}
```
### Other MCP Clients
The server provides comprehensive MCP resources and tools that any MCP-compatible client can discover and use.
## 📝 Supported DNS Record Types
| Type | Description | Example |
|------|-------------|---------|
| **A** | IPv4 address | `192.168.1.100` |
| **AAAA** | IPv6 address | `2001:db8::1` |
| **CNAME** | Domain alias | `example.com` |
| **MX** | Mail server | `mail.example.com` (requires priority) |
| **TXT** | Text data | `v=spf1 include:_spf.google.com ~all` |
| **NS** | Name server | `ns1.example.com` |
| **SRV** | Service record | `0 5 443 example.com` (requires priority) |
## 🔧 API Reference
### VultrDNSClient
Main client class for DNS operations:
```python
client = VultrDNSClient(api_key)
# Domain operations
await client.domains() # List domains
await client.domain("example.com") # Get domain info
await client.add_domain(domain, ip) # Create domain
await client.remove_domain(domain) # Delete domain
# Record operations
await client.records(domain) # List records
await client.add_record(domain, type, name, value, ttl, priority)
await client.update_record(domain, record_id, type, name, value, ttl, priority)
await client.remove_record(domain, record_id)
# Convenience methods
await client.add_a_record(domain, name, ip, ttl)
await client.add_cname_record(domain, name, target, ttl)
await client.add_mx_record(domain, name, mail_server, priority, ttl)
# Utilities
await client.find_records_by_type(domain, record_type)
await client.get_domain_summary(domain)
await client.setup_basic_website(domain, ip)
await client.setup_email(domain, mail_server, priority)
```
### MCP Tools
When running as an MCP server, provides these tools:
- `list_dns_domains()` - List all domains
- `get_dns_domain(domain)` - Get domain details
- `create_dns_domain(domain, ip)` - Create domain
- `delete_dns_domain(domain)` - Delete domain
- `list_dns_records(domain)` - List records
- `create_dns_record(...)` - Create record
- `update_dns_record(...)` - Update record
- `delete_dns_record(domain, record_id)` - Delete record
- `validate_dns_record(...)` - Validate record parameters
- `analyze_dns_records(domain)` - Analyze configuration
## 🛡️ Error Handling
All operations include comprehensive error handling:
```python
result = await client.add_a_record("example.com", "www", "192.168.1.100")
if "error" in result:
print(f"Error: {result['error']}")
else:
print(f"Success: Created record {result['id']}")
```
## 🧪 Development
Clone the repository and install development dependencies:
```bash
git clone https://github.com/vultr/vultr-dns-mcp.git
cd vultr-dns-mcp
pip install -e .[dev] pip install -e .[dev]

## 🚀 What Gets Fixed
### Before (Broken):
```python
# Incorrect async pattern
async def test_tool(self, mcp_server):
result = await client.call_tool("tool_name", {})
# ❌ Missing proper async context
# ❌ No mock configuration
# ❌ Incomplete error handling
```
### After (Fixed):
```python
@pytest.mark.asyncio
async def test_tool(self, mock_vultr_client):
with patch('vultr_dns_mcp.server.VultrDNSServer', return_value=mock_vultr_client):
server = create_mcp_server("test-api-key")
async with Client(server) as client: # ✅ Proper context manager
result = await client.call_tool("tool_name", {})
assert result is not None # ✅ Proper assertions
mock_vultr_client.method.assert_called_once() # ✅ Mock verification
```
## 🧪 Expected Test Results

## Issues Identified and Fixed
### 1. Import Path Problems ✅ FIXED
- **Issue**: Tests had incorrect import paths for vultr_dns_mcp modules
- **Fix**: Updated all import statements to use correct package structure
- **Files affected**: conftest.py, test_mcp_server.py
### 2. Async/Await Pattern Issues ✅ FIXED
- **Issue**: Incorrect usage of async patterns with FastMCP Client
- **Fix**: Fixed async context manager usage and proper await patterns
- **Files affected**: test_mcp_server.py, all async test methods
### 3. Mock Configuration Problems ✅ FIXED
- **Issue**: Mock setup didn't match actual API response structure
- **Fix**: Updated mock configurations to match current Vultr API
- **Files affected**: conftest.py fixtures
### 4. Test Data Structure Mismatches ✅ FIXED
- **Issue**: Sample data didn't match current API response format
- **Fix**: Updated test fixtures with correct data structures
- **Files affected**: conftest.py sample_* fixtures
### 5. Missing Error Handling Tests ✅ FIXED
- **Issue**: Insufficient error scenario testing
- **Fix**: Added comprehensive error handling test cases
- **Files affected**: test_mcp_server.py TestMCPToolErrors class
## Files Created/Updated
### Core Fixes
- `conftest_fixed.py` - Updated test configuration with proper mocks
- `test_mcp_server_fixed.py` - Fixed MCP server tests
- `pyproject_fixed.toml` - Updated dependencies and configuration
- `run_tests_fixed.py` - Improved test runner script
### Key Improvements
1. **Better Mock Setup**: Comprehensive mock responses matching Vultr API
2. **Proper Async Patterns**: Correct FastMCP Client usage throughout
3. **Error Handling**: Robust error scenario testing
4. **Dependency Management**: Updated pyproject.toml with correct versions
5. **Test Organization**: Clear test categorization with pytest markers
## How to Apply the Fixes
### Quick Fix (Recommended)
```bash
# In your vultr-dns-mcp repository directory:
cp conftest_fixed.py tests/conftest.py
cp test_mcp_server_fixed.py tests/test_mcp_server.py
cp pyproject_fixed.toml pyproject.toml
cp run_tests_fixed.py run_tests.py
```
### Manual Application
1. Replace `tests/conftest.py` with `conftest_fixed.py`
2. Replace `tests/test_mcp_server.py` with `test_mcp_server_fixed.py`
3. Update `pyproject.toml` with fixed dependencies
4. Replace `run_tests.py` with improved version
### Install Dependencies
```bash
pip install -e .[dev]
# Or manually:
pip install pytest pytest-asyncio pytest-cov fastmcp httpx pydantic click
```
### Run Tests
```bash
# Run all tests
pytest tests/ -v
# Run only MCP tests
pytest tests/ -m mcp -v
# Run with coverage
pytest tests/ --cov=vultr_dns_mcp --cov-report=html
# Using the improved test runner
python run_tests.py --type mcp --verbose --coverage
```
## Expected Results After Fixes
✅ All basic MCP server tests should pass
✅ Tool invocation tests should work correctly
✅ Resource discovery tests should succeed
✅ Error handling tests should validate properly
✅ Integration workflow tests should complete
✅ Validation logic tests should work as expected
## Common Issues and Solutions
### If tests still fail:
1. **Import Errors**: Ensure you're running tests from the repository root
2. **Async Errors**: Verify pytest-asyncio is installed and configured
3. **Mock Errors**: Check that all mock methods are properly configured
4. **FastMCP Errors**: Ensure compatible FastMCP version is installed
### Debugging Tips:
```bash
# Run single test with maximum verbosity
pytest tests/test_mcp_server.py::TestMCPTools::test_list_dns_domains_tool -vvv
# Check installed packages
pip list | grep -E "(pytest|fastmcp|httpx)"
# Validate test discovery
pytest --collect-only tests/
```
## Next Steps
1. Apply the fixes to your repository
2. Run the test suite to verify all tests pass
3. Consider adding additional test cases for edge scenarios
4. Update CI/CD configuration if needed
5. Document any additional setup requirements
The fixed test suite provides comprehensive coverage of the MCP functionality
while following FastMCP best practices and proper async patterns.
