Health Reminder MCP Server

Instructions

Implementation Reference

• src/server/index.ts:138-146 (handler)

  The core handler function for the 'stop_reminder' tool. It clears the active reminder timer interval if it exists, logs a stop message, and returns true if stopped or false otherwise.

  function stopReminder() {
    if (reminderTimer) {
      clearInterval(reminderTimer);
      reminderTimer = null;
      console.log("✓ 健康提醒已停止");
      return true;
    }
    return false;
  }

• src/server/index.ts:187-194 (registration)

  Registers the 'stop_reminder' tool in the list of available tools, specifying its name, description, and input schema (empty object). This is used for the ListTools response.

  {
    name: "stop_reminder",
    description: "停止健康提醒定时器",
    inputSchema: {
      type: "object",
      properties: {},
    },
  },

• src/server/index.ts:264-277 (handler)

  The dispatch handler in the CallToolRequestSchema that invokes the stopReminder function and formats the response.

  case "stop_reminder": {
    const stopped = stopReminder();
    return {
      content: [
        {
          type: "text",
          text: JSON.stringify({
            success: stopped,
            message: stopped ? "健康提醒已停止" : "当前没有运行中的提醒",
          }, null, 2),
        },
      ],
    };
  }

• src/server/index.ts:190-193 (schema)

  The input schema definition for the 'stop_reminder' tool, which requires no parameters (empty properties).

  inputSchema: {
    type: "object",
    properties: {},
  },

• src/server/index.ts:87-88 (helper)

  Global state variables used by the stopReminder handler: the timer reference that gets cleared and current config.

  let reminderTimer: NodeJS.Timeout | null = null;
  let currentConfig: ReminderConfig = { ...defaultConfig };
