Implementation Reference

• src/index.ts:447-489 (handler)

  The main handler function that creates a new calendar event using Google Calendar API. It destructures arguments, builds the event object with timezone, inserts into primary calendar, and returns success or formatted error.

  private async handleCreateEvent(args: any) {
    try {
      const { summary, location, description, start, end, attendees = [] } = args;
  
      const event = {
        summary,
        location,
        description,
        start: {
          dateTime: start,
          timeZone: Intl.DateTimeFormat().resolvedOptions().timeZone,
        },
        end: {
          dateTime: end,
          timeZone: Intl.DateTimeFormat().resolvedOptions().timeZone,
        },
        attendees: attendees.map((email: string) => ({ email })),
      };
  
      const response = await this.calendar.events.insert({
        calendarId: 'primary',
        requestBody: event,
      });
  
      return {
        content: [
          {
            type: 'text',
            text: `Event created successfully. Event ID: ${response.data.id}`,
          },
        ],
      };
    } catch (error: any) {
      return {
        content: [
          {
            type: 'text',
            text: `Error creating event: ${error.message}`,
          },
        ],
        isError: true,
      };
    }

• src/index.ts:176-206 (schema)

  Input schema for the create_event tool, specifying required fields (summary, start, end) and optional fields (location, description, attendees).

  inputSchema: {
    type: 'object',
    properties: {
      summary: {
        type: 'string',
        description: 'Event title',
      },
      location: {
        type: 'string',
        description: 'Event location',
      },
      description: {
        type: 'string',
        description: 'Event description',
      },
      start: {
        type: 'string',
        description: 'Start time in ISO format',
      },
      end: {
        type: 'string',
        description: 'End time in ISO format',
      },
      attendees: {
        type: 'array',
        items: { type: 'string' },
        description: 'List of attendee email addresses',
      },
    },
    required: ['summary', 'start', 'end']
  },

• src/index.ts:173-207 (registration)

  Registers the create_event tool in the ListToolsRequestSchema handler, providing name, description, and input schema.

  {
    name: 'create_event',
    description: 'Create a new calendar event',
    inputSchema: {
      type: 'object',
      properties: {
        summary: {
          type: 'string',
          description: 'Event title',
        },
        location: {
          type: 'string',
          description: 'Event location',
        },
        description: {
          type: 'string',
          description: 'Event description',
        },
        start: {
          type: 'string',
          description: 'Start time in ISO format',
        },
        end: {
          type: 'string',
          description: 'End time in ISO format',
        },
        attendees: {
          type: 'array',
          items: { type: 'string' },
          description: 'List of attendee email addresses',
        },
      },
      required: ['summary', 'start', 'end']
    },
  },

• src/index.ts:240-241 (registration)

  In the CallToolRequestSchema handler, routes 'create_event' tool calls to the handleCreateEvent method.

  case 'create_event':
    return await this.handleCreateEvent(request.params.arguments);
