Which LangChain version supports this?

LangChain 1.4.0 or newer with the mcp extra (pip install langchain[mcp]). The MCPAdapter lives in the langchain.mcp namespace and is currently in beta.

If I connect WhatsApp Cloud API to my LangChain agent, can I use the same connection in Claude or ChatGPT later?

Yes, and that's the point: the connection is yours, not LangChain's. You paste the same link in any AI you use, and there's nothing new to set up or pay again. Connect a new AI and WhatsApp Cloud API is already there.

Do I need to hand my WhatsApp Cloud API password to my agent?

Never. You sign in once at Vinkius, and we keep your logins encrypted and away from your AI. Your code only ever sees the link, and you can remove it whenever you want.

What can my agent actually do with WhatsApp Cloud API?

Whatever the Connector covers: check data, run actions and bring answers back. The Connector page lists every capability your AI gains, with real examples you can copy.

The tools don't show up. What do I check?

Confirm the URL matches your link exactly and that the Connector is active in your Vinkius account, then call list_tools again. A deactivated Connector stops responding.

Can I remove the access later?

Anytime. Remove the MCPAdapter call from your code and the tools leave your agent. Your Vinkius account keeps the connection and its history either way, ready for the next AI.

Use WhatsApp Cloud API with LangChain

Set up in seconds, once. From then on, your agent gets things done for you: add one adapter call, and WhatsApp Cloud API is live in LangChain.

LangChain + WhatsApp Cloud API

One agent. Your WhatsApp Cloud API, live inside LangChain.

Real prompts, answered with live data. This is the kind of session your agent will run once the adapter is in.

Waiting for input…

Works with modern AI clients that support MCP, including ChatGPT, Claude, Cursor, and more.

These prompts ship with the WhatsApp Cloud API Connector. Once yours is connected, your agent can run them.

The full capability set, the prompts and the observed latency live on the WhatsApp Cloud API Connector page.

Mission Control

See everything your LangChain agents do in WhatsApp Cloud API.

When your LangChain agent runs a tool in WhatsApp Cloud API, it happens inside your code: you see the output, but not the request itself, what data it carried, or whether a rule was broken.

Now every move lands on your screen.

Every execution is recorded, enforced, and shown to you: what ran, what it returned, what was blocked, and why.

Every request your LangChain agents make through WhatsApp Cloud API is logged, enforced and auditable. See how AI Governance turns agent activity into accountability, and what it means for your WhatsApp Cloud API workflows.

What sets us apart

It's not just the Connector that stays safe. Everything your agents do through it is.

Connecting WhatsApp Cloud API to your AI is step one. But an open line between your agents and WhatsApp Cloud API is only half the story: without protection, every action they take runs unguarded.

That's why protection doesn't stop at the door.

Every action your agents take through the Connector runs inside our infrastructure: signed activity logs, automatic key rotation, spending limits that pause instead of surprise, and a sandbox that isolates every execution.

Tamper Proof Activity Log

Every request your agents make in WhatsApp Cloud API is recorded and signed, so any change to the history becomes detectable.

Automatic Key Rotation

We rotate security keys every 24 hours. Your WhatsApp Cloud API connection stays protected without any manual work.

Spending Protection

We enforce the spending limit you choose and pause actions that exceed it until approval is received. Your WhatsApp Cloud API actions never surprise you.

Isolated Sandbox

Every execution through WhatsApp Cloud API runs isolated, with 34+ security rules covering memory, CPU, network access, file handling and execution.

Security Event Streaming

Security events flow to Splunk, Datadog or your own webhook, so WhatsApp Cloud API activity lands in the tools you already rely on.

Instant Resume

Idle connections resume in 3 to 5 ms while preserving their state, keeping your LangChain sessions responsive.

Malicious File Protection

We detect compressed files designed to exhaust system resources and block them before they ever reach WhatsApp Cloud API.

Credential Validation

We test your WhatsApp Cloud API credentials before saving them. Invalid credentials are rejected instead of being stored.

Separate Usage Limits

Usage stays isolated per account, so activity in one connection never consumes another account's allowance.

One Connector, one link, and the whole operation is protected. Not just the connection: everything your agents do through it.

These guarantees are not add-ons: they are the infrastructure every WhatsApp Cloud API connection runs on. Read how our infrastructure protects everything your LangChain agents do, end to end.
