# Connect LinkedIn DMs to Codex

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

Part of the [LinkedIn DMs setup guide](https://sealgate.ai/connect/linkedin) , 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.

Agent prompt easier Terminal faster

## Set up Codex for LinkedIn DMs, 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=linkedin-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=linkedin-codex bash $env:SEALGATE_UTM_CAMPAIGN='seo-connect'; $env:SEALGATE_UTM_CONTENT='linkedin-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 LinkedIn DMs 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=linkedin-codex first, since starting there pre-approves the Beeper connector. Then follow the setup steps at https://sealgate.ai/connect/linkedin/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 LinkedIn DMs

- Sync your LinkedIn DMs to your CRM so no conversation slips through.

- Draft follow-ups to warm replies for you to review and send.

- Triage inbound messages and surface the ones that look like real leads.

- Pull context on a contact from a thread before your next call.

## Why connect LinkedIn DMs 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 LinkedIn DMs to Codex: FAQ

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

Can an AI agent manage my LinkedIn DMs? Yes. Once connected through SealGate, your agent can read, draft, and send LinkedIn direct messages, from local tools or cloud apps like ChatGPT and Claude.

Can it sync LinkedIn DMs to my CRM? Yes. Syncing LinkedIn conversations into a CRM is one of the workflows this was built for, so replies and context land next to the right contact automatically.

Is automating LinkedIn messages safe? It runs on your own account through the Beeper desktop app, and SealGate logs the metadata of every action (which tool ran, when, and by which agent), never the content of your DMs. Keep a human in the loop for outreach: let the agent draft, and you approve before anything sends.

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 LinkedIn 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.
