LetsBot — WhatsApp Business MCP

npx add-mcp 'https://letsbot.net/mcp'

LetsBot MCP server — WhatsApp Business for Claude, ChatGPT, Cursor and any MCP client

LetsBot's remote MCP server connects AI assistants to a WhatsApp Business account on LetsBot: read and answer customer conversations, send approved templates, run campaigns and chatbots, manage contacts and get reports.

• Server URL: https://letsbot.net/mcp (Streamable HTTP)
• Auth: OAuth 2.1 with PKCE and dynamic client registration (Claude, ChatGPT), or a LetsBot API key as a Bearer token (Cursor, VS Code, Gemini CLI, Continue)
• Server card: https://letsbot.net/.well-known/mcp/server-card.json
• Docs: https://letsbot.net/en/whatsapp-mcp.html

Requirements

• A LetsBot account with the API + MCP add-on (US$69.99/month, VAT included, on top of any plan; plans start at US$6.35/month), or an active 14-day free trial.
• A WhatsApp number connected to LetsBot for sending. An API key (LetsBot panel → Developers → Authentication Data) is issued once a channel is connected.
• Bulk campaigns also need the Bulk Messaging add-on.

Connect

Recommended: OAuth (Claude, ChatGPT and any client that supports it): you sign in with your LetsBot account and never handle a key. Use an API key only in developer tools, and keep it out of shared or committed config files.

Claude — Settings → Connectors → add LetsBot from the directory, or "Add custom connector":

URL: https://letsbot.net/mcp
Auth: OAuth 2.1 + PKCE (sign in with your LetsBot account)

ChatGPT — install the LetsBot app, or add a server with https://letsbot.net/mcp and sign in.

Cursor — ~/.cursor/mcp.json:

{
  "mcpServers": {
    "letsbot": {
      "url": "https://letsbot.net/mcp",
      "headers": { "Authorization": "Bearer YOUR_LB_API_KEY" }
    }
  }
}

VS Code — .vscode/mcp.json:

{
  "servers": {
    "letsbot": {
      "type": "http",
      "url": "https://letsbot.net/mcp",
      "headers": { "Authorization": "Bearer YOUR_LB_API_KEY" }
    }
  }
}

Gemini CLI:

gemini mcp add --transport http --header "Authorization: Bearer YOUR_LB_API_KEY" letsbot https://letsbot.net/mcp

Continue — config.yaml:

mcpServers:
  - name: letsbot
    type: streamable-http
    url: https://letsbot.net/mcp
    requestOptions:
      headers:
        Authorization: Bearer YOUR_LB_API_KEY

What it can do

More than 80 tools in every workspace (up to 166 when optional areas such as CRM, deals, tasks, tickets and bookings are on): messages and templates, live-chat inbox, contacts and labels, campaigns, chatbot, store orders and abandoned carts, reports and an owner briefing.

Safety

• Every send (messages, templates, campaigns) returns a preview first and runs only after an explicit confirm: true.
• OAuth access is scoped to the signed-in user's own LetsBot account and can be revoked at any time.
• Team roles, API keys, billing and channel disconnection stay read-only over MCP.
