MCP Reminders

Instructions

Implementation Reference

• src/index.ts:145-153 (handler)

  The core handler function in ReminderManager that marks a reminder as completed by updating its status to 'completed', adding a completion timestamp, saving to JSON file, and returning true on success.

  completeReminder(id: string): boolean {
    const reminder = this.reminders.get(id);
    if (!reminder || reminder.status !== 'active') return false;
    
    reminder.status = 'completed';
    reminder.completed = new Date().toISOString();
    this.saveReminders();
    return true;
  }

• src/index.ts:367-376 (handler)

  The MCP dispatch handler for 'complete_reminder' tool calls, which extracts the id argument, calls the core completeReminder method, and formats a response message.

  case 'complete_reminder': {
    const { id } = args as { id: string };
    const success = reminders.completeReminder(id);
    return {
      content: [{ 
        type: 'text', 
        text: success ? `Reminder ${id} marked as completed.` : `Reminder ${id} not found.` 
      }],
    };
  }

• src/index.ts:267-276 (schema)

  Input schema definition for the complete_reminder tool, requiring a single 'id' string parameter.

  inputSchema: {
    type: 'object',
    properties: {
      id: {
        type: 'string',
        description: 'Reminder ID'
      }
    },
    required: ['id'],
  },

• src/index.ts:264-277 (registration)

  Tool registration in the ListTools response, defining name, description, and input schema for complete_reminder.

  {
    name: 'complete_reminder',
    description: 'Mark a reminder as completed',
    inputSchema: {
      type: 'object',
      properties: {
        id: {
          type: 'string',
          description: 'Reminder ID'
        }
      },
      required: ['id'],
    },
  },
