# Windows Diagnostics MCP Server
A Model Context Protocol (MCP) server that provides comprehensive Windows system diagnostic capabilities to AI agents. This server allows agents to access Windows event logs, crash information, system uptime, stability analysis, and Windows registry diagnostics.
## Features
### System Diagnostics
- **System Diagnostics**: Comprehensive analysis of Windows events, crashes, and system health
- **BSOD Detection**: Identifies Blue Screen of Death events and critical system errors
- **Shutdown Analysis**: Tracks expected and unexpected system shutdowns
- **Application Crash Monitoring**: Monitors application crashes and failures
- **System Stability Scoring**: Provides stability analysis with actionable recommendations
- **Uptime Tracking**: Reports system uptime and boot information
### Registry Diagnostics
- **Registry Search**: Search the Windows registry by keyword
- **Startup Program Analysis**: Analyze startup programs for suspicious entries
- **System Component Scanning**: Scan services, drivers, and uninstall entries for issues
- **Orphaned Entry Detection**: Find orphaned registry entries pointing to non-existent files
- **Registry Health Assessment**: Overall registry health evaluation
- **Security Risk Scanning**: Scan for potential security risks in the registry
## Installation
### Prerequisites
- Windows 10/11 or Windows Server
- Node.js 18+
- PowerShell 5.1+ (built into Windows)
- Administrator privileges (recommended for full functionality)
- PowerShell execution policy configured to allow script execution
### Setup Steps
1. **Clone or download the files**:
```bash
mkdir windows-diagnostics-mcp
cd windows-diagnostics-mcp
```
2. **Save the TypeScript server code** as `src/index.ts`
3. **Create package.json** with the provided configuration
4. **Create tsconfig.json** with the provided TypeScript configuration
5. **Install dependencies**:
```bash
npm install
```
6. **Configure PowerShell execution policy** (if not already set):
```powershell
Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
```
Or for system-wide access (requires Administrator):
```powershell
Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope LocalMachine
```
7. **Build the server**:
```bash
npm run build
```
## Configuration
### For Claude Desktop
Add this to your Claude Desktop configuration file (`%APPDATA%\Claude\claude_desktop_config.json`):
```json
{
"mcpServers": {
"windows-diagnostics": {
"command": "node",
"args": ["C:\\path\\to\\your\\windows-diagnostics-mcp\\build\\index.js"],
"env": {
"NODE_ENV": "production"
}
}
}
}
```
**Important**: For full functionality, run Claude Desktop as Administrator to ensure proper access to event logs and registry.

The server can be started with:
```bash
node build/index.js
```
## Available Tools
The MCP server provides the following tools that agents can use:

## Usage Examples
Once configured with an MCP-compatible client, agents can use commands like:
### System Diagnostics
- "Check my system for any crashes in the last week"
- "Analyze my Windows system stability"
- "Show me recent BSOD events"
- "What's my current system uptime?"
- "Give me a comprehensive diagnostic report"
### Registry Diagnostics
- "Search the registry for entries related to 'Adobe'"
- "Analyze my startup programs for suspicious entries"
- "Check for orphaned registry entries"
- "Scan my registry for security risks"
- "Give me an overall registry health assessment"
- "Scan system components for issues"
## Security Considerations
- **Administrator Rights**: Run with administrator privileges for complete event log and registry access
- **PowerShell Execution**: The server executes PowerShell scripts to gather system information
- **Registry Access**: Registry operations require appropriate permissions and can potentially impact system stability
- **Local Only**: This server only accesses local system information, no network requests
- **Event Log Access**: Requires appropriate permissions to read Windows Event Logs
- **Execution Policy**: PowerShell execution policy must allow script execution
## Troubleshooting
### Common Issues
1. **PowerShell Execution Policy Error**:
```
cannot be loaded because running scripts is disabled on this system
```
**Solution**: Configure PowerShell execution policy:
```powershell
Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
```
2. **Access Denied Errors**:
- Run the MCP client (e.g., Claude Desktop) as Administrator
- Some event logs and registry keys require elevated privileges
- Check user account permissions
3. **Registry Access Errors**:
- Ensure proper permissions for registry access
- Some registry keys require SYSTEM-level access
- Run as Administrator for full registry access
4. **JSON Parse Errors**:
- Check that PowerShell is outputting valid JSON
- Verify no additional output is being written to stdout
- Check for PowerShell version compatibility
5. **No Events Found**:
- Normal if system has been stable
- Try increasing the `daysBack` parameter
- Check if Event Log service is running
6. **Script Execution Blocked**:
- Verify PowerShell execution policy settings
- Check for antivirus software blocking script execution
- Ensure PowerShell modules are not corrupted
### Debugging
Enable debug logging by setting environment variable:
```bash
set DEBUG=mcp:*
node build/index.js
```
### PowerShell Execution Policy Details
The server requires PowerShell scripts to execute. Common execution policies:
- **Restricted**: No scripts allowed (default on some systems)
- **RemoteSigned**: Local scripts allowed, downloaded scripts must be signed
- **Unrestricted**: All scripts allowed (not recommended)
Check current policy:
```powershell
Get-ExecutionPolicy
```
Recommended setting for this server:
```powershell
Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
```

## Output Format
The server provides structured information including:
- **Event timestamps** in ISO format
- **Event descriptions** in plain English
- **Stability scoring** (0-100 scale)
- **Actionable recommendations**
- **System uptime statistics**
- **Memory dump information**
- **Hardware error summaries**
- **Registry key paths and values**

## Development
To modify or extend the server:
1. **Edit source**: Modify `src/index.ts`
2. **Rebuild**: Run `npm run build`
3. **Test**: Use MCP inspector or compatible client
4. **Add tools**: Follow the MCP SDK patterns for new diagnostic functions
### Adding New Diagnostic Features
To add new diagnostic capabilities:
1. Extend the PowerShell script with additional event log queries or registry operations
2. Add new tool definitions in the `ListToolsRequestSchema` handler
3. Implement corresponding handler methods
4. Update the documentation
5. Test with appropriate permissions
### PowerShell Script Guidelines
When adding new PowerShell functionality:
- Use `ConvertTo-Json` for structured output
- Handle errors gracefully with try-catch blocks
- Test with different execution policies
- Validate registry key existence before access
- Use appropriate PowerShell cmdlets for registry operations
