PostMCP Companion · iOS & Android

Your agent’s social queue, in your pocket

The Companion app is the same workspace your MCP client publishes into — the queue, the calendar, the agent — built for the moments you are away from the keyboard. It is in a closed beta on TestFlight and Google Play: apply below, pick your platform, and the download links arrive by email once an admin approves you.

The whole queue, one thumb

Every scheduled post across your workspaces, by day. Drag one to a new slot, retry a failed one, or pause a network from the lock screen.

Push the moment it matters

Published, failed, token expiring, teammate needs an approval — a notification with the fix one tap away, not a dashboard you remember to check.

Compose and publish with media

Write once, attach photos or a Short from your camera roll, and publish to LinkedIn, X, Threads, Bluesky, Facebook, Instagram and YouTube Shorts.

Your agent, in chat form

“Announce the launch on Friday.” Read what it drafted, approve it, and watch it land in the calendar — the same agent your MCP client talks to.

  • Same account as the web dashboard
  • Face ID / fingerprint unlock
  • No plan or checkout inside the app
Closed beta · seats are limited

Apply for the Companion beta

Tell us which platform you carry and how you will use the app. An admin approves applications by hand, and the email you enter here is the one the app lets in.

    Apply

    Pick Android, iOS or both and send the form.

  2. 2

    Get approved

    We review every application. Most hear back within a day.

  3. 3

    Install

    The approval email links you to TestFlight and Google Play testing.

Which platform do you want access on?

The email you enter is the one the app checks at sign-in. We only use it for the beta.

Beta questions

Who gets approved?
Anyone with a PostMCP account and a real use for the app. We approve by hand because TestFlight and Play internal testing cap the tester list, so a sentence about how you publish helps.
Do I need a PostMCP account first?
Not to apply. You will need one to sign in — the app uses the same Google or Apple sign-in as the web dashboard, and the address you apply with is the one it checks.
Can I ask for both platforms?
Yes. Pick both and the approval email carries both links. If you only asked for one, the other link is still included in case you switch phones.
What does the app not do?
Connect new social accounts and manage billing — both live on the web dashboard. The app is for the queue, the calendar, publishing and the agent.
