Plug WhatsApp, SMS and calls into any LLM

2Chat ships an official MCP server that exposes your WhatsApp, WABA, SMS and voice operations as tools. Add it to Claude, ChatGPT or any MCP-compatible client and let your AI agent talk to customers, manage contacts and run automations on its own.

// claude_desktop_config.json { "mcpServers": { "2chat": { "url": "https://mcp.2chat.io/mcp", "type": "http" } } }

Works with the LLMs and agents you already use

If your assistant speaks the Model Context Protocol, it can speak to your customers through 2Chat. No glue code, no proxy server, just point it to our endpoint and authenticate.

Add 2Chat to Claude Desktop, Claude Code or claude.ai with a single MCP entry. Claude can read, write and reply to WhatsApp messages on your behalf.

Use 2Chat as a custom connector inside ChatGPT and ChatGPT-based agents. Trigger sends, lookups and call workflows directly from a chat.

Wire 2Chat into OpenClaw together with Hermes, the open agent from Nous Research, and other self-hosted MCP runtimes. Bring messaging and voice into your own agent stack.

Cursor, Cline, n8n, custom SDK agents. Anything that speaks MCP can call the 2Chat tools the same way.

33 tools across messaging, voice and account

Every action in 2Chat is exposed as a typed MCP tool with structured arguments. Your LLM picks the right one and runs it against your account in real time.

Inspect the connected workspace, current user and billing status before taking action.

Create, search, update and remove contacts in your 2Chat address book from natural language.

Send messages, fetch conversations, check if a number is on WhatsApp, manage statuses and read your catalog.

List groups, fetch participants and read group messages so your agent can reason about ongoing group chats.

Send template messages, sync templates and estimate template costs across countries on the official WABA channel.

Trigger transactional and one-time SMS to any country directly from your AI agent.

List virtual numbers, look up call history, inspect call details and check call pricing on demand.

Hand a customer query to Claude or ChatGPT and it will draft, send and follow up on WhatsApp using your real number, with full conversation context loaded as needed.

Send and receive messages from a single tool call

Pull conversation history before answering

Verify a phone is on WhatsApp before reaching out

Ask your agent to find a contact, update tags, fix a phone number or merge duplicates. The contact tools handle it without you opening the dashboard.

Bulk lookups by name, phone or attributes

Send a one-time SMS, check a virtual number's call history or pull pricing for an outbound call. Your agent can orchestrate voice and SMS the same way it sends a WhatsApp message.

Setup is the same regardless of which LLM client you use. If it accepts an MCP server URL, you are minutes away from running tools.

Sign up for free and connect a WhatsApp, SMS or virtual number. No WhatsApp Business API account required.

Drop the 2Chat MCP URL into your client's configuration: Claude Desktop config file, ChatGPT connector or any MCP-aware tool.

Ask your assistant to message a customer, find a contact or check a number. It will pick the right tool and run it on your account.

2Chat operates as an official Meta Tech Provider, meeting the highest standards for security, stability, and compliance in enterprise environments.

Frequently asked questions about the MCP server

MCP is an open standard introduced by Anthropic that lets large language models call external tools through a typed, structured interface. The 2Chat MCP server makes our APIs available to any compatible LLM with no custom integration work.

Anything that speaks MCP. Today that includes Claude (Desktop, Code and claude.ai), ChatGPT through custom connectors, OpenClaw running Hermes from Nous Research, Cursor, Cline, n8n's MCP node and a growing list of open-source agents.

No. Most tools work with a regular WhatsApp or WhatsApp Business number connected via QR code. WABA-specific tools become available once you connect a WABA number to your workspace.

The MCP server authenticates with your 2Chat user API key. You can find and rotate the key from the developer settings of your account, and revoke access at any time.

Yes. Most MCP clients let you approve tools individually before they run, and 2Chat workspace permissions still apply on top of that. The server only exposes what the API key has access to.

The MCP server itself is included with every 2Chat plan. Tool calls consume the same quotas as the rest of the API. For example, sending a WhatsApp message counts as one outbound message on your plan.
