WhatsApp FAQs

Question 1

How does WhatsApp MCP Server integrate with LLMs?

Accepted Answer

It runs as a lightweight HTTP daemon (e.g., on `127.0.0.1:8765`). MCP clients like Claude Desktop or Cursor connect to this HTTP endpoint, enabling LLMs to call the exposed WhatsApp tools for messaging, group management, and more.

Question 2

What specific WhatsApp functionalities can LLMs control?

Accepted Answer

LLMs gain access to 41 tools for comprehensive control, including sending and receiving messages, managing groups, sharing media, creating polls, setting privacy controls, handling disappearing messages, resolving contacts (LID resolution), and accessing conversation history.

Question 3

How do I set up and pair my WhatsApp account with the MCP Server?

Accepted Answer

After building the single-binary Go daemon, run `./bin/whatsapp-mcp serve`. Then, open `http://127.0.0.1:8765/pair` in a browser and scan the QR code with your phone's WhatsApp 'Linked Devices' feature to establish the connection. The session persists to a local SQLite database.

Question 4

What is the WhatsApp MCP Server?

Accepted Answer

The WhatsApp MCP Server is an independent, open-source Go daemon that exposes your personal WhatsApp account as 41 Model Context Protocol (MCP) tools. This allows large language models (LLMs) to programmatically interact with WhatsApp features.

Question 5

Is the WhatsApp MCP Server an official WhatsApp product?

Accepted Answer

No, it is an independent open-source project and is not affiliated with, endorsed by, or otherwise associated with Meta Platforms, Inc. or WhatsApp. It uses the whatsmeow library for interoperability.
