Implementation Reference

• index.js:723-725 (handler)

  Handler for the matrix_time_analysis tool. Forwards the tool arguments to the Google Apps Script API endpoint 'matrixTimeAnalysis' using the callAPI helper function.

  case "matrix_time_analysis":
    result = await callAPI("matrixTimeAnalysis", args);
    break;

• index.js:520-537 (schema)

  Input schema for the matrix_time_analysis tool, defining optional parameters startDate, endDate, and groupBy with enum values.

  inputSchema: {
    type: "object",
    properties: {
      startDate: {
        type: "string",
        description: "Start date YYYY-MM-DD (optional, defaults to beginning)"
      },
      endDate: {
        type: "string",
        description: "End date YYYY-MM-DD (optional, defaults to today)"
      },
      groupBy: {
        type: "string",
        description: "How to group the analysis",
        enum: ["topic", "bug", "week", "day"]
      }
    }
  }

• index.js:517-538 (registration)

  Registration of the matrix_time_analysis tool in the MCP server's ListTools response, including name, description, and input schema.

    name: "matrix_time_analysis",
    description: "Analyze time spent across Matrix entries. Tracks total time by topic, bug UID, or week. Parses time markers like [30m], [2h] from entries.",
    inputSchema: {
      type: "object",
      properties: {
        startDate: {
          type: "string",

• index.js:74-131 (helper)

  Helper function callAPI used by all proxied tools, including matrix_time_analysis, to make HTTP POST requests to the Google Apps Script web app.

  async function callAPI(action, data = {}) {
    debugLog('=== API CALL START ===');
    debugLog(`Action: ${action}`);
