What is this?

This MCP Server lets you control WhatsApp Business directly from Claude AI. Send messages, receive replies, manage templates, track analytics — all through natural language.

Example: Just tell Claude "Send a message to +56 9 1234 5678 saying the order is ready" and it does it.

Anti-Spam Protection

Every outbound message is checked by the built-in MessageGuard before sending. No bad prompt can turn into spam.

Protections by Tier

How It Works

1. Allowlist — Enable it with manage_allowlist to restrict who can receive messages. If enabled, only numbers on the list can be messaged.

2. Per-recipient rate limit — Max messages to the same number per hour. Prevents flooding a single contact.

3. Unique recipient limit — Max different numbers per hour. Prevents mass-messaging campaigns.

4. Content filter — Blocks messages matching known spam patterns (promotional language, chain messages).

5. Duplicate detection — Blocks sending the same message to the same number within a short window.

Quick Example

You: "Send a message to +1234567890 saying hello"
Claude: ❌ Blocked — recipient not in allowlist. Use manage_allowlist to add them.

You: "Add +1234567890 to my allowlist"
Claude: ✅ Added. Allowlist now has 1 number.

You: "Send a message to +1234567890 saying hello"
Claude: ✅ Message sent!

AI Auto-Reply (Enterprise) — WhatsApp Chatbot

Enterprise customers can enable AI-powered automatic replies to incoming WhatsApp messages. When a customer messages you, the server calls an AI provider to generate a response and sends it back automatically.

Supported AI Providers

Each client uses their own AI API key — you are not charged for AI calls.

How to Set Up Auto-Reply

Step 1: Get an API key from your preferred provider:

• Groq (free): console.groq.com → API Keys → Create

• OpenAI: platform.openai.com → API Keys

• Claude: console.anthropic.com → API Keys

• Gemini: aistudio.google.com/apikey

• DeepSeek: platform.deepseek.com → API Keys

Step 2: Configure auto-reply via Claude:

You: "Configure auto-reply with Groq. My API key is gsk_xxxxx.
      Use this system prompt: You are a friendly customer service agent
      for my online store. Answer questions about products, shipping,
      and returns in Spanish. Our website is https://mystore.com"

Claude: ✅ Auto-reply ENABLED with Groq (Llama 3.3 70B)

Step 3: That's it! Incoming WhatsApp messages will now get automatic AI responses.

Auto-Reply Tools (3 tools) ENTERPRISE

Features

• Conversation memory — the AI remembers previous messages per customer (configurable, up to 20 messages)

• Business hours — only auto-reply during work hours, with a custom off-hours message

• Per-recipient rate limit — max 20 auto-replies per customer per hour (configurable)

• Custom system prompt — tell the AI who it is, what it sells, how to respond

• Any model — use the default or specify a custom model name

Example Conversation

Customer: "Hola, cuánto cuesta?"
Bot: "Hola Ricardo, tenemos planes Free, Pro ($29 USD/mes) y
      Enterprise ($99 USD/mes). Visita https://mysite.com para más detalles."

Customer: "Tienen envío gratis?"
Bot: "Sí, el envío es gratuito en pedidos mayores a $50.
      ¿Te gustaría hacer un pedido?"

FAQ

Q: Do I need my own WhatsApp Business API account? A: For the hosted version, your API key gives you access to the shared test environment. For production with your own phone number, you'll need a Meta Business Account.

Q: How do I get my API key after purchase? A: You receive it via email from Lemonsqueezy. You can also retrieve it anytime at: https://whatsapp-mcp-server.eosspirit.workers.dev/billing/api-key?email=YOUR_EMAIL

Q: Can I cancel my subscription? A: Yes, anytime through Lemonsqueezy. Your API key will be deactivated at the end of the billing period.

Q: What happens if my API key stops working? A: Check that your subscription is active. If your payment failed, update your payment method in Lemonsqueezy.

Q: Is there a free tier? A: Yes! 5 core tools are available for free with no API key needed. Just connect to the MCP endpoint.

Q: How does anti-spam protection work? A: Every message goes through the MessageGuard which checks allowlists, per-recipient rate limits, unique recipient limits, and spam content patterns. Use manage_allowlist to control who can receive messages, and get_messaging_safety_status to check your current limits.

Q: Can someone use a bad prompt to send spam? A: No. The free tier only allows 5 messages to 3 different numbers per hour. All tiers have spam pattern detection and per-recipient rate limiting. You can enable an allowlist so messages can only go to pre-approved numbers.

Q: Can I self-host this? A: Yes, the code is open source (MIT). See the Self-Hosting section above.
