Connect OpenCode to WhatsApp via MCP

OpenCode is a terminal-based AI coding assistant that supports MCP. With Pons, you can access your WhatsApp Business messages without leaving the terminal — search conversations, check who's waiting for a reply, and send messages.

This guide takes about 3 minutes.

Prerequisites

• OpenCode installed
• A Pons account at pons.chat with at least one WhatsApp Business number connected (setup guide)

Step 1: Create an API key

1. Sign in to pons.chat
2. Click the key icon to open the API Key Manager
3. Click Create Key
4. Name it "OpenCode" and select the scopes you need:
   • read — list conversations, search messages
   • write — mark messages as read, send reactions
   • send — send text and template messages
5. Copy the key

Step 2: Configure OpenCode

Edit ~/.config/opencode/config.json and add Pons to the MCP section:

{
  "mcp": {
    "pons": {
      "type": "remote",
      "url": "https://pons.chat/api/mcp",
      "headers": {
        "Authorization": "Bearer pons_your_api_key_here"
      }
    }
  }
}

Replace pons_your_api_key_here with your API key.

Step 3: Restart OpenCode

OpenCode reads MCP configuration on startup. Restart it to pick up the new server.

Step 4: Use it

Ask OpenCode:

"List my WhatsApp conversations"

It'll call the list_conversations tool and return your recent chats.

More things you can do:

• "Who's waiting for a WhatsApp reply?"
• "Search my WhatsApp for 'deployment'"
• "Send 'Done, it's deployed' to +49123456789"
• "What did the last message from Alex say?"

Why WhatsApp in the terminal?

If you're a developer who spends most of the day in a terminal, checking WhatsApp means context-switching to your phone or a browser tab. With Pons + OpenCode, you can quickly check and reply to business messages without leaving your workflow.

It's especially useful for:

• Quick triage — "show me unanswered WhatsApp messages" between git commits
• Searching — find that API key or tracking number someone sent you over WhatsApp
• Automated replies — let the AI draft a response and send it after your approval

Scoped keys for safety

If you only want to read messages from OpenCode (no sending), create a key with just the read scope. OpenCode will be able to list and search conversations but not send anything. See the API Keys guide for more.
