Overview

AI-generated overview

Connects an AI assistant to a WhatsApp Business inbox so it can see who is waiting, follow-ups, and replies.

What you can do
Chatty: WhatsApp Business is a remote MCP server that links an assistant to a WhatsApp Business inbox. According to its description, it surfaces who is waiting on a response, follow-ups, and replies. No tool list is published, so the exact actions available are not documented here.
When to use it
Consider it when you handle customer or client conversations on WhatsApp Business and want an assistant to help track unanswered messages, pending follow-ups, and replies inside Claude or ChatGPT.
Requirements
A remote MCP endpoint at asistente.letschatty.com over streamable HTTP, with OAuth authentication required. No environment variables or headers are declared. A WhatsApp Business account and network access are implied.
Before you install
OAuth grants the server access to your WhatsApp Business inbox, so review the scopes requested before authorizing. The description mentions replies, which suggests the assistant may send messages on your behalf; confirm whether it can write or send before relying on it. No tool list is published, so verify what it can actually do.

Installation

In SourceWeft

  1. Open Chatty: WhatsApp Business in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.letschatty%2Fwhatsapp/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

Tools

This server asks you to sign in, so SourceWeft could not read its tools without an account and has not indexed them. What a connected account sees can depend on that account and its permissions.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
