What you can do with this MCP connector
Yo, this 2Chat MCP Server lets your AI client handle all your WhatsApp messin'. Forget the hassle of opening up the actual app—your agent can send everything through simple chat commands. You can send text, images, PDFs, and voice notes to any single number or a whole group UUID. You'll also get to manage groups; your agent will create new WhatsApp groups and toss specified participants into them.
Need to make sure a number is legit before you hit send? Your agent runs the check_number tool to verify if a phone number is actually registered and active on WhatsApp. You can run list_numbers to see all the WhatsApp phone numbers hooked up to the 2Chat account, so you know what sender IDs you're working with.
If you need to know which groups your connected number is part of, you use list_groups to grab a list of all those group memberships. Sending a message is simple with send_message; you just tell your agent who to send it to and what it is. You can also manage multiple accounts, letting your agent communicate across several WhatsApp numbers through one API workspace.
How 2Chat MCP Works
- 1 Subscribe to the server and provide your 2Chat API Key.
- 2 Your AI client connects using the Model Context Protocol.
- 3 Your agent executes commands (e.g., 'Send a message to +12223334444') which trigger the underlying 2Chat API calls.
The bottom line is, your AI agent interacts with WhatsApp via the 2Chat API, treating it like another tool it can call.
Who Is 2Chat MCP For?
The marketing team running campaigns needs this. The community manager managing large user bases needs this. Operations engineers automating internal alerts need this. Anyone who needs their AI client to talk to people on WhatsApp needs this.

Automates internal team notifications and workflows, treating WhatsApp groups as a primary communication channel.
What Changes When You Connect
- Your agent sends rich content—text, images, PDFs—via
send_message. You don't hit WhatsApp's template limits; you just send. - Stop manually organizing chats. Use
create_groupto build new WhatsApp groups andsend_messageto announce things to the whole roster. - Improve delivery success rates. Before running any campaign,
check_numbervalidates if the recipient's number is active on WhatsApp. - Keep track of your presence.
list_groupspulls up every group your account belongs to, letting your agent know what context it's operating in. - Manage multiple accounts easily.
list_numbersshows every connected WhatsApp number, letting your agent switch sender IDs as needed. - Get real-time updates. Your agent monitors incoming messages and delivery status, keeping you in the loop on everything that happens.
Real-World Use Cases
Onboarding a new team project
The project lead needs a dedicated chat space. They ask their agent: 'Use create_group to make a group called 'Project Phoenix' and add John and Sarah.' The agent executes the tool, and the group is ready for immediate use.
Running a mass campaign
A marketing manager wants to reach 50 clients. They first ask the agent to run check_number on the list. Once validated, the agent uses send_message to send a personalized update, guaranteeing the message actually gets delivered.
Updating internal policies
Operations staff needs to alert all department heads. They ask the agent to use list_groups to find the 'Executive Announcements' group, then use send_message to broadcast the new policy document.
Client outreach and cleanup
A sales rep has a list of old contacts. They use check_number on each one. If the number fails validation, they flag it for cleanup, ensuring they only send messages to active contacts.
The Tradeoffs
Manual Group Management
Manually going into WhatsApp Web to create a group, add people, and then copy/paste the announcement message into the chat.
→
Use the agent. First, call create_group with the desired participants. Then, trigger send_message to post the announcement to the new group.
Blind Sending Messages
Running a mass message campaign by sending messages to numbers without checking if the account is active, resulting in failed deliveries and wasted effort.
→
Always run check_number on your target list first. Only proceed with send_message once the numbers pass validation.
Confusing Sender IDs
Forgetting which WhatsApp account to send from, leading to messages going out of the wrong primary number or failing entirely.
→
Use list_numbers to see all linked WhatsApp accounts. Then, specify the correct sender ID when calling send_message.
Assuming Group Existence
Trying to send a group-wide announcement without first confirming the group's ID or confirming membership.
→
Call list_groups first. This confirms you are a member and gives you the correct UUID needed for send_message.
When It Fits, When It Doesn't
Use this if your workflow requires WhatsApp interaction to be automated, multi-step, and stateful. You need your agent to perform sequences like: 'Check if Number A exists; if yes, create Group B; then send Message C.' The tools like check_number, create_group, and send_message give you that sequence control. Don't use this if you just need to check a single number once, or if your communication doesn't rely on WhatsApp at all—in that case, a standard database API tool works better. If you only need to list groups, list_groups handles it, but if you need to do something with that list, you need the full suite.

Works with Claude, ChatGPT, Cursor, and more
The Model Context Protocol standardizes how applications expose capabilities to LLMs. Instead of operating in isolation, your AI gains direct access to external platforms, live data, and real-world actions through secure, standardized connections.
This server provides 5 capabilities that interface natively with Claude, ChatGPT, Cursor, and any MCP client. No middleware. No custom integration required.
Available Capabilities
WhatsApp communication shouldn't require jumping between tabs.
Today, managing communications means logging into WhatsApp Web, navigating to the contacts list, manually checking membership in a group, and then composing the message. This process is slow, error-prone, and forces you to copy UUIDs and sender IDs into your workflow.
With the 2Chat MCP Server, your agent handles the whole flow. You ask it to 'Announce X to the Dev Team.' The agent handles `list_groups`, verifies the group ID, and uses `send_message`—all in one shot. You get the outcome, not the clicks.
2Chat MCP Server: Automate WhatsApp messaging.
Forget manually running checks. You use `check_number` to confirm a number is valid before any campaign starts. Then, you use `list_numbers` to ensure your agent sends the message from the right account, and finally, `send_message` sends the content. It's a clean, verifiable sequence.
The difference is that you stop thinking about the API calls. You just tell your agent what you want done. The server handles the complexity of the workflow, ensuring every step, from number validation to final delivery, works.
Common Questions About 2Chat MCP
How do I check if a WhatsApp number is valid using 2Chat MCP Server? +
Call the check_number tool. This verifies if a phone number is registered on WhatsApp, which prevents failed delivery errors before you send a message.
Can I use the 2Chat MCP Server to create new WhatsApp groups? +
Yes, use the create_group tool. You just specify the desired name and the participants, and the server builds the group for you.
What is the difference between `list_numbers` and `list_groups` in 2Chat MCP Server? +
list_numbers shows all WhatsApp accounts connected to your 2Chat workspace. list_groups shows all groups your specific number is a member of.
Can `send_message` send more than just text? +
Yes. send_message supports sending images, PDFs, and voice notes, not just plain text. You just need to provide the correct media type.
How do I use `list_numbers` and `list_groups` together in the 2Chat MCP Server? +
You first run list_numbers to get all connected WhatsApp IDs. Then, you pass one of those numbers to list_groups to see what groups that specific account belongs to. This two-step process helps you map your available accounts to your community structure.
What happens if I try to send a message to a number that isn't on WhatsApp using `send_message`? +
The system checks for validity first. If the number isn't registered, send_message fails and returns an error code, allowing your AI client to catch the failure and prompt you to fix the target number before retrying.
Does the 2Chat MCP Server support sending different types of media with `send_message`? +
Yes, send_message supports text and various media types. You can send text, public URLs, and more, letting your AI agent deliver rich content to any specified chat or group.
Which number should I use for sending messages after running `list_numbers`? +
After running list_numbers, you get a list of all connected 'from_number' IDs. You select the specific ID you want your agent to use as the sender for the message via send_message.
Can I manage WhatsApp groups with this server? +
Yes! 2Chat provides dedicated tools to create groups, list groups your number belongs to, and send messages to group UUIDs.
Do I need official WhatsApp Business API approval? +
No. 2Chat works by linking your existing WhatsApp number (Personal or Business) via a QR code, so you don't need official Meta approval or template restrictions.
How can I check if a number is on WhatsApp? +
You can use the check_number tool to verify if a specific phone number is registered on WhatsApp before attempting to send a message.
