# Connect WhatsApp to Codex

Let Codex read, triage, and reply across WhatsApp, governed by SealGate and policy-checked on every call.

Part of the [WhatsApp setup guide](https://sealgate.ai/connect/whatsapp) , which covers every agent and how the connection works under the hood.

Paste this into your coding agent, or run it yourself in a terminal.

## Set up Codex for WhatsApp, step by step

- 1 ### Create your SealGate account from this link If you do not already have a SealGate account, sign up at the link below. Starting there pre-approves the Beeper connector, so the install needs no dashboard approval afterward. https://dashboard.sealgate.ai/start/personal-messaging?utm_source=sealgate.ai&utm_campaign=seo-connect&utm_content=whatsapp-codex
- 2 ### Install the connector on your computer Run the installer in a terminal. It sets up the Beeper desktop app bridge and the sealgate-stdiod tunnel that carries your messaging apps to the SealGate gateway. Requires macOS or Windows with Beeper signed in. macOS / Linux Windows (PowerShell) curl -fsSL https://sealgate.ai/install-beeper.sh | SEALGATE_UTM_CAMPAIGN=seo-connect SEALGATE_UTM_CONTENT=whatsapp-codex bash $env:SEALGATE_UTM_CAMPAIGN='seo-connect'; $env:SEALGATE_UTM_CONTENT='whatsapp-codex'; powershell -ExecutionPolicy Bypass -Command "irm https://sealgate.ai/install-beeper.ps1 | iex"
- 3 ### Add SealGate to Codex Register the gateway as a streamable HTTP MCP server, then log in. The login opens your browser for OAuth, and codex mcp list should show sealgate afterwards. codex mcp add sealgate --url https://mcp.sealgate.ai/mcp codex mcp login sealgate
- 4 ### Approve the connector if you skipped the signup link If you signed up through the link above, Beeper is already approved. Otherwise open the SealGate dashboard, approve it once, and decide whether Codex may send messages or only read them.
- 5 ### Ask Codex to work with your messages Start a Codex session and ask for something concrete. Codex calls the messaging tools through SealGate, and every call is policy-checked and logged. Summarize my unread message threads and draft replies for me to approve

Please help me connect WhatsApp to Codex through SealGate on my machine. If I do not already have a SealGate account, have me sign up at https://dashboard.sealgate.ai/start/personal-messaging?utm_source=sealgate.ai&utm_campaign=seo-connect&utm_content=whatsapp-codex first, since starting there pre-approves the Beeper connector. Then follow the setup steps at https://sealgate.ai/connect/whatsapp/codex.md and stop whenever I need to act myself: approving this device in the browser when the installer asks, and, only if I already had an account, approving the Beeper connector in the SealGate dashboard.

Requires macOS or Windows (Linux is experimental) with the Beeper desktop app installed.

## Connecting Codex

Codex adds the SealGate gateway as an MCP server in its configuration, so it can call your messaging tools straight from the terminal as you work. See the [Codex setup guide](https://sealgate.ai/docs/getting-started) for the exact steps.

## What Codex can do with WhatsApp

- Draft replies to your unread WhatsApp chats and send them once you approve.

- Summarize busy family or work group chats and pull out the action items.

- Send the same update to a list of contacts without copy and pasting.

- Search past conversations to answer a question or find a shared file.

Ready to let Codex handle your WhatsApp? Paste the setup prompt into your coding agent and you are connected in a couple of minutes.

## Why connect WhatsApp through SealGate

One setup for every app, works with cloud and mobile agents, fully governed and logged, and your messages are never stored.

### One setup, every network

The same command connects your whole unified inbox, so you are not wiring up a separate bridge for each app.

### Works with cloud and mobile agents

A local daemon tunnels the connector out, so ChatGPT, Claude, and other cloud agents can use it, not just CLI tools.

### Governed and logged

Every tool call runs through SealGate policies and lands in an audit trail that records only metadata, never your message content, so access stays under your control.

### SealGate never stores your messages

Message content only passes through in transit to be checked against your policies, and is never stored or read by anyone at SealGate.

## Connecting WhatsApp to Codex: FAQ

Can Codex read and send WhatsApp messages? Yes. Codex adds the SealGate gateway as an MCP server, which lets it use your WhatsApp tools. Because it runs on your own machine, you can work with WhatsApp straight from the terminal while you code.

Do I need the WhatsApp Business API? No. SealGate connects to your own WhatsApp account through the Beeper desktop app, so there is no separate Business API account or third-party number to provision.

Is it safe to give an AI agent access to WhatsApp? Your WhatsApp login is never stored on SealGate's servers. Every tool call the agent makes runs through SealGate policy checks and is written to an audit log that records only metadata (which tool ran, when, and which agent ran it), never your message content, so you control and can review exactly what it did without SealGate storing your messages.

What does SealGate store about my messages? SealGate routes each tool call to your connector and back, holding the request and response in memory only long enough to apply your policies, then discarding them. That check is automated: the gateway inspects the traffic programmatically to enforce your rules, and no one at SealGate can read your messages. They are never persisted and never used to train any model. SealGate keeps only call metadata (which tool ran, when, and which agent ran it), never the tool-call parameters or results, so your conversations and who you are talking to are never stored on SealGate's servers.

Does it work with cloud agents, not just CLI tools? Yes. A small local daemon called stdiod tunnels your local WhatsApp connector to any cloud or mobile agent, so apps like ChatGPT and Claude can use it too, not just CLI tools on the same machine.
