Implementation Reference
- src/tools/messaging.ts:153-227 (handler)Primary handler implementation for the 'whatsapp_send_video' tool. Defines the tool metadata, inline input schema for MCP, and the async handler function that validates input using Zod schema and sends the video via WSAPI client.export const sendVideoMessage: ToolHandler = { name: 'whatsapp_send_video', description: 'Send a video message to a WhatsApp contact or group. Can send from URL or base64.', inputSchema: { type: 'object', properties: { to: { type: 'string', description: 'Recipient phone number (with @s.whatsapp.net) or group ID (with @g.us)', }, videoBase64: { type: 'string', description: 'Base64 encoded video data (alternative to videoURL)', optional: true, }, videoURL: { type: 'string', description: 'URL of the video to send (alternative to videoBase64)', optional: true, }, mimeType: { type: 'string', enum: ['video/mp4', 'video/3gp', 'video/mov', 'video/avi'], description: 'MIME type of the video', }, caption: { type: 'string', description: 'Caption for the video (max 1024 characters)', optional: true, }, viewOnce: { type: 'boolean', description: 'Whether the video should be sent as view-once', optional: true, }, mentions: { type: 'array', items: { type: 'string' }, description: 'List of phone numbers to mention in the caption', optional: true, }, replyTo: { type: 'string', description: 'ID of the message being replied to', optional: true, }, isForwarded: { type: 'boolean', description: 'Whether the message should be marked as forwarded', optional: true, }, }, required: ['to', 'mimeType'], }, handler: async (args: any) => { const input = validateInput(sendVideoMessageSchema, args) as SendVideoMessageInput; logger.info('Sending video message', { to: input.to, mimeType: input.mimeType, hasCaption: !!input.caption, viewOnce: input.viewOnce, }); const result = await wsapiClient.post('/messages/video', input); logger.info('Video message sent successfully', { messageId: result.id }); return { success: true, messageId: result.id, message: 'Video message sent successfully', }; }, };
- src/validation/schemas.ts:34-46 (schema)Zod schema (sendVideoMessageSchema) used for validating input parameters in the whatsapp_send_video handler. Includes refinements to ensure video data is provided via base64 or URL.export const sendVideoMessageSchema = z.object({ to: chatIdSchema, videoBase64: base64Schema.optional(), videoURL: urlSchema.optional(), mimeType: z.enum(['video/mp4', 'video/3gp', 'video/mov', 'video/avi']), caption: z.string().max(1024).optional(), viewOnce: z.boolean().optional(), mentions: z.array(phoneNumberSchema).optional(), replyTo: messageIdSchema.optional(), isForwarded: z.boolean().optional(), }).refine(data => data.videoBase64 || data.videoURL, { message: "Either videoBase64 or videoURL must be provided", });
- src/server.ts:53-79 (registration)Registration logic in the MCP server where messagingTools (containing whatsapp_send_video) is included in toolCategories and registered in the tools Map for MCP tool listing and execution.private setupToolHandlers(): void { logger.info('Setting up tool handlers'); // Register all tool categories const toolCategories = [ messagingTools, contactTools, groupTools, chatTools, sessionTools, instanceTools, accountTools, ]; toolCategories.forEach(category => { Object.values(category).forEach(tool => { if (this.tools.has(tool.name)) { logger.warn(`Tool ${tool.name} already registered, skipping`); return; } this.tools.set(tool.name, tool); logger.debug(`Registered tool: ${tool.name}`); }); }); logger.info(`Registered ${this.tools.size} tools`); }
- src/tools/messaging.ts:544-555 (registration)Export of messagingTools object that bundles the sendVideoMessage handler, which is later imported and registered in the MCP server.export const messagingTools = { sendTextMessage, sendImageMessage, sendVideoMessage, sendLinkMessage, sendReactionMessage, editMessage, deleteMessage, markMessageAsRead, starMessage, ...advancedMessagingTools, };
- src/validation/schemas.ts:317-317 (schema)TypeScript type definition for SendVideoMessageInput inferred from the Zod schema, used in the handler for type assertion.export type SendVideoMessageInput = z.infer<typeof sendVideoMessageSchema>;
