What Is a WhatsApp MCP Server? The Three Kinds, and Which One You Need (2026)
A WhatsApp MCP server turns WhatsApp actions into tools an AI can call. Here is what that means in plain words, the three kinds that exist, and how to tell which one fits you.

You typed "WhatsApp MCP server" into a search box and got repositories, a Meta setup guide and a few hosted services. They all use the same three words, and they are not the same thing. This page explains what the term means, the three kinds you will run into, and how to choose one.
What is a WhatsApp MCP server?
A WhatsApp MCP server is a program that exposes WhatsApp actions, such as reading a chat or sending a message, as tools that an AI model can call. It speaks the Model Context Protocol (MCP), an open standard that AI apps use to talk to outside tools. You add the server to your AI app once. After that, you can ask the AI in plain words to look at a chat or send something, and the AI calls the matching tool.
The server does not contain an AI. It is the bridge between the AI you already use, such as Claude or ChatGPT, and your WhatsApp.
What can an AI do through one?
That depends on the server. On the hosted Blueticks server, a standard account sees 12 tools, according to the live MCP manifest:
| Tool | What it covers |
|---|---|
chats_read | Reads chats and messages. Read-only: it changes nothing in WhatsApp |
chats_write | Sends into a chat immediately, and marks read, reacts, archives |
contacts | The WhatsApp contacts known to your connected account |
groups | The WhatsApp groups on your account |
audiences | Reusable contact lists used as recipients of campaigns |
campaigns | Paced bulk sends to an audience, with pause, resume and cancel |
tasks | Tasks on your own Blueticks boards |
webhooks | URLs that receive an HTTPS POST when Blueticks events occur |
scheduled_messages_read and scheduled_messages_write | Queued messages: list them, check delivery, send later, edit, cancel |
engine | Status and controls of the connected WhatsApp account |
utils | Small helpers, such as the current date and time |
For the limits of each tool, see WhatsApp MCP tools. Other servers expose fewer or more tools. Count them before you assume.
The three kinds of WhatsApp MCP server
The kinds differ in how they reach WhatsApp. That one choice drives setup effort, what the AI can read, and the risk to your number. The full comparison goes through the named projects. The short version:
| Kind | How it reaches WhatsApp | You run it? | What to expect |
|---|---|---|---|
| Official Cloud API server | Meta's WhatsApp Business Platform | Yes, self-hosted | Needs a Meta Business account and a verified number. Built for messaging customers, not for reading your own chats |
| Self-hosted open-source server | A linked-device connection to your own number, run on your machine | Yes | Free and local. Setup means a build step and a QR scan, and it stops when your machine stops |
| Hosted server | A linked-device connection to your own number, run for you | No | Add a URL and sign in. Someone else keeps the connection alive |
Two things to know before you choose:
- The Meta route messages customers from a business number. The linked-device routes work from your own number and can read your existing chats. Those are different jobs.
- Linked-device servers are not an official Meta product. The comparison covers the risk for each type, so read it before you connect a number you cannot afford to lose.
How the Blueticks server fits
Blueticks is the hosted kind. On its MCP page, the transport is described as a WhatsApp Web linked device on your own number: not the Meta Cloud API, and not an official Meta product.
- Address:
https://api.blueticks.co/mcp. - Sign-in: OAuth 2.0 with PKCE for the connector. The server also accepts an API key for clients that cannot do OAuth.
- Claude: open Settings, then Connectors, choose Add custom connector, name it Blueticks, paste the address, click Connect, and approve access. The step-by-step is in connect WhatsApp to Claude.
- ChatGPT: add a custom MCP server with the same address and OAuth. See connect WhatsApp to ChatGPT.
- Coding tools: a local package,
npx -y @blueticks/mcp, with abt_live_key inBLUETICKS_API_KEY. See Claude Code, VS Code, Codex CLI, Cursor and Windsurf. - Plans: the connector works on every plan. The free plan is limited to 5 requests per 6 hours.
What to ask first
Start with a read, because a read changes nothing. Two prompts to try, which are examples and not recorded output:
- "List the chats where the last message is from someone else and I have not replied."
- "Summarise what was decided in my team group today."
Only once those work should you let the AI send anything. Approve each send yourself and read the tool name before you click.
How to choose
- You want to message customers at scale from a verified business number: the Meta Cloud API route.
- You want to tinker locally and own every piece: a self-hosted open-source server.
- You want Claude or ChatGPT on your own number with nothing to host: a hosted server.

Frequently asked questions
What does MCP stand for? Model Context Protocol. It is an open standard for connecting AI apps to outside tools and data.
Is a WhatsApp MCP server the same as the WhatsApp Business API? No. The Business API is Meta's platform for messaging customers from a registered business number. A WhatsApp MCP server is the tool layer an AI uses, and it may sit on the official API or on a linked-device connection, depending on the kind.
Do I need to code to use one? Not for a hosted server. In Claude or ChatGPT you add a connector by address and sign in. The local package and self-hosted projects need a terminal.
Can the AI read my old chats? A linked-device server can read chats on the connected account, which the Cloud API route cannot. Reading is a separate tool from sending, so you can approve one without the other.
Does it work on a free plan? On Blueticks the connector works on every plan, with 5 requests per 6 hours on the free plan.
