A Model Context Protocol server providing LLM Agents with system utilities and tools, including IP geolocation, network diagnostics, system monitoring, cryptographic operations, and QR code generation.

## Model Context Protocol

The Model Context Protocol (MCP) enables communication between:

- **Clients**: Claude Desktop, IDEs, and other MCP-compatible clients
- **Servers**: Tools and resources for task management and automation
- **LLM Agents**: AI models that leverage the server's capabilities

        "NODE_ENV": "production"
      }
    }
  }
}
```

## Tools

### Network Operations
```typescript
// Get geolocation data
const geo = await mcp.use('toolkit-mcp-server', 'geolocate', {
  query: '8.8.8.8'
});

// Check connectivity
const conn = await mcp.use('toolkit-mcp-server', 'checkConnectivity', {
  host: 'example.com',
  port: 443
});
```

### System Operations
```typescript
// Get system information
const sysInfo = await mcp.use('toolkit-mcp-server', 'getSystemInfo', {});

// Get load average
const load = await mcp.use('toolkit-mcp-server', 'getLoadAverage', {});
```

### Security Operations
```typescript
// Generate hash
const hash = await mcp.use('toolkit-mcp-server', 'hashData', {
  input: 'test data',
  algorithm: 'sha256'
});

// Generate UUID
const uuid = await mcp.use('toolkit-mcp-server', 'generateUUID', {});
```

### Generator Operations
```typescript
// Generate QR code
const qr = await mcp.use('toolkit-mcp-server', 'generateQRCode', {
  data: 'https://example.com',
  type: 'svg'
});
```
