Can Codex ring my phone when a script finishes?

Yes, with an anything alarm. Ask Codex to make one; it returns a private link, and a POST to that link rings every phone that joined. After a ring the alarm stays quiet for the time chosen when it was made, so a retry loop rings once.

A time alarm is a real alarm on iPhone and Android and rings through silent mode. An anything alarm rings full screen on Android; on iPhone it arrives as a time-sensitive alert with the alarm's sound, so keep the ringer on.

Does LFG Alarm see my code?

No. LFG Alarm only receives what Codex sends when it uses LFG Alarm's tools.

Connect LFG Alarm to Codex CLI

Before you start

Get the LFG Alarm app on your phone from Google Play or the App Store, and sign in. Your AI agent makes the alarms; the app is what rings them.
Codex CLI installed and signed in.
Have your LFG Alarm sign-in handy. You will sign in once, on lfg.gm, to let Codex use your account.

Connect it

In a terminal, add the server:

codex mcp add lfg-alarm --url https://mcp.lfg.gm

Or open ~/.codex/config.toml (for every project) and add it yourself:

[mcp_servers.lfg-alarm]
url = "https://mcp.lfg.gm"

codex mcp login lfg-alarm

A browser opens on lfg.gm: sign in with your LFG Alarm account and tap Allow. Codex registers itself on its own, so there is no client ID to paste.

Start codex and type /mcp. LFG Alarm should be in the list of active servers.

The ChatGPT desktop app and the Codex IDE extension read the same configuration, so once it is added it is there too. These steps follow OpenAI's own docs; if a flag has changed, run codex mcp --help.

Use it while Codex works

Codex runs long jobs: a refactor across a repo, a test suite, a migration. Ask it to set a one-off alarm for when the job should be done, then step away. Your phone rings out loud, which is hard to miss in a way a terminal bell is not.

Theo asks Codex to set a 45 minute alarm called "Review the PR" before it starts a big rename, then goes for a walk.
Priya runs an overnight data backfill and asks Codex for an anything alarm. Codex hands back a private link and adds a curl -X POST to it as the script's last line, so her phone rings when the job really ends. See How to make any app, script or feed ring your phone.

Try it

Once it is connected, ask in plain words:

try this

Have your AI agent make it.

Paste this into ChatGPT, Claude, Grok or any AI agent that can add a connector, not into the LFG Alarm app. The setup steps come with it: get the LFG Alarm app, connect it to your agent once, and your agent makes the alarm in your account.

Use LFG Alarm to set a one-off time alarm for 30 minutes from now called "Check the refactor". Then tell me the date and time it will ring.

Already have the LFG Alarm app and connected it to your AI agent?

Why it works. A one-off from now, which is how a wait in the terminal works, and Codex tells you the exact time.

More ideas: "Wake me at 7:00 every weekday and call it Standup", "Make a friends alarm for Friday at 4:00pm called Release and add my friends [username] and [username]", or "List my alarms". Codex can set time, price, post, event, wallet, trader and anything alarms; list, change, turn on or off and delete them; and add your friends or a group once you confirm. See Using LFG Alarm from your AI agent.

If it does not work

The browser never opens. Run codex mcp login lfg-alarm again. Adding the server does not start the sign-in on its own.
Codex cannot open a browser (an SSH session or a container). Use a personal key instead: in LFG Alarm, open Settings > Connected AI apps > Make a key, put it in an environment variable, and add bearer_token_env_var = "LFG_ALARM_KEY" under [mcp_servers.lfg-alarm]. The key acts as you, so keep it out of shared machines and CI.
LFG Alarm is not in /mcp. Check the address is exactly https://mcp.lfg.gm and that you edited the config.toml Codex is reading.

Disconnect

Run codex mcp remove lfg-alarm, or delete its block from config.toml. Your alarms stay in your LFG Alarm account and keep ringing.
