Connect Zernio to Claude and one message posts your video to 8 apps, with its own caption on each. The full setup is below, plus every prompt. It works in Codex too.

HOW IT WORKS
THE FULL SETUP · 9 STEPS
Zernio is the service that talks to every social app for you. The first 2 connected accounts are free, and signing up doesn't ask for a card.
Affiliate link: buildwithneej earns a commission if you sign up.
Start free on Zerniofirst 2 accounts free · affiliate linkIn the Zernio dashboard, click each platform and log in to it. Instagram has to be a Business or Creator account. Facebook asks you to pick a Page, because personal profiles can't be posted to.
Open Zernio →In Claude (web, desktop or the phone app), open Settings > Connectors > Add custom connector. Name it Zernio and paste this URL. Claude sends you to Zernio to sign in. Click Approve and you're connected.
https://mcp.zernio.com/mcp
Use Settings > Connectors for this. Editing the Claude Desktop config file doesn't work for hosted connectors like Zernio.
Same connector, one command each. In Claude Code, run the first line, then type /mcp inside Claude Code to sign in. In Codex, run the add command, then the login command. Both open a Zernio sign-in page where you click Approve.

Ask Claude to list your accounts. You should see every app you connected in step 2. If one is missing, reconnect it in the Zernio dashboard.

Claude can't open files on your computer, so it hands you an upload link instead. Drop the video there (the link lasts 30 minutes and takes files up to 5 GB), then reply "uploaded".
I want to post a video. Give me an upload link.
Ask for a dry run the first time so you can read every caption before anything goes live. Asking for a different caption per app matters: a plain cross-post sends the same text everywhere. Once you say go, Claude replies with a live link for each app.
Post this video to TikTok, YouTube Shorts, Instagram and Threads. Write a different caption for each one. Show me a dry run first and don't publish until I say go.
Zernio pulls post stats from every connected app, so Claude can compare them in one answer.
Which app got the most views this week?
Zernio's docs list analytics as an add-on, so check that your plan includes it before you count on this one.
Zernio charges per connected account. X is billed on its own and needs a card from the first post: $0.015 a post, $0.20 if the post has a link. Set a monthly X spend cap in the dashboard and keep links out of your X captions.
| Connected accounts | Price |
|---|---|
| 1 to 2 | Free |
| 3 to 10 | $6 per account a month |
| 11 to 100 | $3 per account a month |
