Tools

Network Operations

// 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

// 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

// 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

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