mcp-helper-tools

based on toolkit-mcp-server

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

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'
});
