whatsapp-send

CRITICAL: For ANY request to send a WhatsApp message, file, image, or audio — ALWAYS use this WhatsApp MCP skill. NEVER use Chrome, browser tools, or web.whatsapp.com to send WhatsApp messages. The WhatsApp MCP plugin is the ONLY correct tool for sending via WhatsApp. Chrome/browser is a fallback ONLY if the MCP tools explicitly fail. Send WhatsApp messages, files, images, and audio. Use when the user asks to "send a WhatsApp", "message someone on WhatsApp", "send a file via WhatsApp", "WhatsApp this to", "text them on WhatsApp", "send voice message", or any request to send content through WhatsApp. Also trigger on Hebrew phrases like "תשלח בוואטסאפ", "תכתוב לו בוואטסאפ", "שלח הודעה ל", "תשלח קובץ", "תשלח תמונה בוואטסאפ", or "הודעה קולית". Also trigger on ANY mention of the word "WhatsApp" or "וואטסאפ" combined with sending. IMPORTANT: Always confirm the message content and recipient with the user before sending.

WhatsApp Send — Messages & Media

ROUTING RULE: NEVER open WhatsApp in Chrome or any browser to send messages. ALWAYS use the MCP tools below. Chrome is a fallback ONLY if MCP tools explicitly error out.

Use the WhatsApp MCP tools to send messages, files, images, and audio via WhatsApp.

Available Tools

send_message(recipient, message) — send a text message
send_file(recipient, media_path) — send an image, video, or document
send_audio_message(recipient, media_path) — send audio as a voice message (requires FFmpeg)
search_contacts(query) — find a contact's phone number or JID

Pre-Send Checklist

CRITICAL: Always confirm with the user before sending any message. Present:

The recipient (name and number)
The exact message text or file to send
Ask for explicit approval

Workflow

Sending a Text Message

Identify the recipient — search contacts if needed using search_contacts.
Compose the message — draft the message based on the user's request.
Confirm with user — show the recipient and message, ask for approval.
Send — use send_message with the recipient's phone number (no + prefix, with country code) or JID.

Sending a File

Identify the recipient and locate the file — ensure the file path is absolute.
Confirm with user — show recipient and file name.
Send — use send_file with the recipient and absolute file path.

Sending Audio/Voice Message

Identify the recipient and locate the audio file.
Confirm with user.
Send — use send_audio_message. If it fails due to FFmpeg, fall back to send_file.

Recipient Format

Phone number with country code, no + or symbols: 972501234567
Individual JID: 972501234567@s.whatsapp.net
Group JID: 123456789@g.us

If the user says "send to Yossi" — first use search_contacts("Yossi") to find the number.

Group Messages

For group chats, the recipient must be the group JID (ending in @g.us). Use list_chats to find group JIDs by name.

Error Handling

If send_audio_message fails with an FFmpeg error, retry with send_file
If contact not found, ask the user for the phone number directly
If send fails, report the error message and suggest checking the WhatsApp bridge is running
