Overview

AI-generated overview

Lets an assistant send and manage WhatsApp Web messages, media, chats, and group members through a linked session.

What you can do
Provides tools to send text and media, reply to messages, and list chats. It can create groups, list, add, and remove group participants, check whether a number exists, and read a contact's about text. A converse tool handles ambiguous requests conversationally.
When to use it
Useful when you want an assistant to handle WhatsApp messaging and group administration from a chat interface, such as sending updates, replying to contacts, or managing group membership.
Requirements
A remote MCP endpoint at the provider's host, reached over streamable HTTP. The description refers to a linked WhatsApp Web session, so a connected WhatsApp account is implied. No environment variables or headers are declared.
Before you install
The tools send messages and media, create groups, and add or remove participants, which changes data and is visible to other people. Messages and contact details pass through a third-party remote service. No authentication is declared, so confirm how the linked session is secured before use.

Installation

In SourceWeft

  1. Open WhatsApp Web Agent by Nova (CIVAI) in the dashboard and add it to a workspace.
  2. 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/co.civai.nova%2Fwhatsapp-web-agent/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.
