Implementation Reference

• src/index.ts:289-302 (handler)

  The main handler function for the 'get_presentation_info' tool. It calls the slidesService to get the presentation details and formats a text response with title, slide count, and page size.

  private async handleGetPresentationInfo(args: {
    presentationId: string;
  }): Promise<CallToolResult> {
    const info = await this.slidesService.getPresentationInfo(args.presentationId);
  
    return {
      content: [
        {
          type: 'text',
          text: `Presentation: ${info.title}\nSlide count: ${info.slideCount}\nPage size: ${info.pageSize.width.magnitude} x ${info.pageSize.height.magnitude} ${info.pageSize.width.unit}`,
        },
      ],
    };
  }

• src/index.ts:110-123 (registration)

  Tool registration in the ListToolsRequestSchema handler, defining the name, description, and input schema for 'get_presentation_info'.

  {
    name: 'get_presentation_info',
    description: 'Get information about a Google Slides presentation',
    inputSchema: {
      type: 'object',
      properties: {
        presentationId: {
          type: 'string',
          description: 'The ID of the Google Slides presentation',
        },
      },
      required: ['presentationId'],
    },
  },

• src/index.ts:113-122 (schema)

  Input schema for the 'get_presentation_info' tool, specifying the required 'presentationId' parameter.

  inputSchema: {
    type: 'object',
    properties: {
      presentationId: {
        type: 'string',
        description: 'The ID of the Google Slides presentation',
      },
    },
    required: ['presentationId'],
  },

• src/slides.ts:210-228 (helper)

  Supporting utility method in GoogleSlidesService that interacts with the Google Slides API to retrieve presentation information including title, slide count, and page size.

  async getPresentationInfo(presentationId: string) {
    await this.auth.refreshTokenIfNeeded();
    const slides = this.auth.getSlidesClient();
  
    try {
      const response = await slides.presentations.get({
        presentationId
      });
  
      return {
        title: response.data.title,
        slideCount: response.data.slides?.length || 0,
        pageSize: response.data.pageSize
      };
    } catch (error) {
      console.error('Error getting presentation info:', error);
      throw new Error(`Failed to get presentation info: ${error}`);
    }
  }
