Implementation Reference

• src/index.ts:704-732 (handler)

  The handler function that executes the tool logic: validates bot_id and image_url, calls the API to send the image, and returns a success message.

  private async sendImageToMeeting(args: Record<string, unknown>) {
    const bot_id = args.bot_id as string;
    const image_url = args.image_url as string;
    
    if (!bot_id || typeof bot_id !== 'string') {
      throw new Error("Missing or invalid required parameter: bot_id");
    }
    
    if (!image_url || typeof image_url !== 'string') {
      throw new Error("Missing or invalid required parameter: image_url");
    }
  
    if (!image_url.startsWith('https://')) {
      throw new Error("Image URL must start with https://");
    }
    
    await this.makeApiRequest(`/api/v1/bots/${bot_id}/output_image`, "POST", {
      url: image_url
    });
  
    return {
      content: [
        {
          type: "text",
          text: `✅ Image sent to meeting from bot ${bot_id}\n📷 Image URL: ${image_url}\n\n💡 The image should now be displayed in the meeting (Google Meet only)!`,
        },
      ],
    };
  }

• src/index.ts:352-365 (schema)

  Input schema defining parameters bot_id and image_url for the tool.

  inputSchema: {
    type: "object",
    properties: {
      bot_id: {
        type: "string",
        description: "ID of the bot that should display the image",
      },
      image_url: {
        type: "string",
        description: "HTTPS URL of the image to display",
      },
    },
    required: ["bot_id", "image_url"],
  },

• src/index.ts:349-366 (registration)

  Tool registration in the listTools response, defining name, description, and input schema.

  {
    name: "send_image_to_meeting",
    description: "Send an image to the meeting through the bot (Google Meet only)",
    inputSchema: {
      type: "object",
      properties: {
        bot_id: {
          type: "string",
          description: "ID of the bot that should display the image",
        },
        image_url: {
          type: "string",
          description: "HTTPS URL of the image to display",
        },
      },
      required: ["bot_id", "image_url"],
    },
  },

• src/index.ts:434-435 (registration)

  Switch case in CallToolRequest handler that dispatches to the sendImageToMeeting method.

  case "send_image_to_meeting":
    return await this.sendImageToMeeting(args);
