WhatsApp Campaigns for Grok

Install WhatsApp Campaigns in Grok

.mcp.json (in your project root)

{
  "mcpServers": {
    "whatsapp-campaigns": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@wa-campaigns/agent-toolkit"
      ],
      "env": {
        "WA_GATEWAY_URL": "<WA_GATEWAY_URL>",
        "WA_AGENT_KEY": "<WA_AGENT_KEY>"
      }
    }
  }
}

Grok Build reads Claude Code's .mcp.json and Claude Desktop's config unchanged, so a server you have already set up there needs nothing new. The Grok web app and X integration do not take custom servers. Grok docs
