Toolkit MCP Server

Instructions

Implementation Reference

• src/tools/system.ts:78-91 (handler)

  The main handler function for the getLoadAverage tool. It calls os.loadavg() to retrieve the 1, 5, and 15-minute load averages and formats them as JSON in the MCP response content.

  handler: async () => {
    const [oneMin, fiveMin, fifteenMin] = os.loadavg();
    
    return {
      content: [{
        type: 'text',
        text: JSON.stringify({
          oneMinute: oneMin,
          fiveMinutes: fiveMin,
          fifteenMinutes: fifteenMin
        }, null, 2)
      }]
    };
  }

• src/tools/system.ts:71-77 (schema)

  Tool metadata including name, description, and input schema (no parameters required).

  getLoadAverage: {
    name: 'getLoadAverage',
    description: 'Get system load average for 1, 5, and 15 minutes',
    inputSchema: {
      type: 'object',
      properties: {}
    },

• src/index.ts:28-35 (registration)

  Registers the getLoadAverage tool by spreading systemTools into the allTools object, which is used by the MCP server's listTools and callTool request handlers.

  const allTools: ToolKit = {
    ...systemTools,
    ...networkTools,
    ...geoTools,
    ...generatorTools,
    ...dateTimeTools,
    ...securityTools
  };

• src/index.ts:5-5 (registration)

  Imports the systemTools object containing the getLoadAverage tool definition.

  import { systemTools } from './tools/system.js';
