# Codex

> Connect Codex to the Hypersender MCP server.

Connect Hypersender to Codex using the CLI.

**1. Add Hypersender**

Run:

```bash theme={null}
codex mcp add hypersender --url https://app.hypersender.com/mcp
codex mcp login hypersender
codex mcp list
```

**2. Sign in and authorize**

Sign in to Hypersender in your browser. Choose the instances and permissions to share, then authorize the connection and return to your client.

**3. Try it out**

Start a fresh Codex session and ask:

```text theme={null}
Using hypersender, list my approved instances. Do not send anything.
```

Codex OAuth and a WhatsApp text send have been confirmed in production.
