WhatsApp for the AI agents you use

Claude, ChatGPT and other AI agents can search your chats, show who is waiting on you, and draft replies. Pick your app for the exact steps.

Not on the list?

If your app can add a remote MCP server, or your agent can run terminal commands, it can use WhatSync.

Any MCP client

Paste the server URL wherever your app adds MCP servers and sign in when it asks. WhatSync supports OAuth with automatic client registration, so there is no client ID to copy.

Agents that run commands

If your agent can run terminal commands, it can use the WhatSync CLI. Sign in once with npx whatsync login, then it runs npx whatsync and gets JSON back.

WhatsApp CLI

Your own agent

Building with an agent framework or your own code? Connect it to the same server, or call the same WhatsApp tools from your code.

Which AI agents work with WhatsApp?

Any AI app that can add a remote MCP server and sign in with OAuth. This page has setup guides for 19 of them, from ChatGPT and Claude to Cursor, Codex and OpenClaw. Each guide lists what you need, like a paid plan or a country limit.

What is an MCP server?

MCP, the Model Context Protocol, is the standard way AI apps connect to other tools. WhatSync is a hosted WhatsApp MCP server: it gives your AI tools to read, search and send WhatsApp messages. More about WhatsApp MCP.

Do I need a separate account for each AI app?

No. Sign in with the same WhatSync account in each app. Each app sees the chats you chose to save.

My AI app is not on the list. Will it work?

If it can add a remote MCP server and sign in with OAuth, it should. Paste the server URL and sign in, then ask it which WhatsApp account it sees to check it worked. Building your own agent? Use the developer docs.

Can my AI agent send WhatsApp messages on its own?

It can, if the app lets the send tool run without asking you. Most apps can ask first: keep the send tools on manual approval. Telling the agent to wait is not the same as that setting. A normal send goes to one person or group; a Business campaign goes to every opted-in customer on its list.

Is it safe to link my personal WhatsApp?

It uses WhatsApp's Linked devices, and you can unlink it from your phone at any time. You choose which chats are saved. Bulk or unsolicited messages break WhatsApp's rules and can get a number restricted, on a personal number and on the Business API.

Link your WhatsApp once. Choose your AI app.

One WhatSync account works in all of them. Each guide says what you need.
