Connect Claude or ChatGPT

PostHonk works as a connector (an MCP server) for Claude and ChatGPT. Once it's connected, ask your assistant to write a post and schedule it, and it lands in your PostHonk queue. You'll need a PostHonk account. You sign in to it when you connect.

Your connector URL

Claude

  1. Open Settings, then Connectors.
  2. Choose Add custom connector and name it PostHonk.
  3. Paste your PostHonk URL and click Add, then Connect.

Works on claude.ai and the Claude desktop and mobile apps.

ChatGPT

  1. Open Settings, then Apps, then Advanced settings, and turn on Developer mode.
  2. Back in Apps, choose Create app and name it PostHonk.
  3. Paste your PostHonk URL, set authentication to OAuth, then Create and sign in.

Developer mode is available on paid ChatGPT plans.

What your assistant can do

  • add_to_queue: Schedules a post. PostHonk picks the time from your schedule, unless you ask for a specific one.
  • list_queue: Shows what's queued and when each post goes out. Read only.
  • update_post: Changes a queued post's text or time.
  • remove_from_queue: Deletes a queued post so it's never published.

Try asking:

  • “Turn these notes into a LinkedIn post and add it to my PostHonk queue.”
  • “What's in my PostHonk queue this week?”
  • “Make Thursday's post shorter.”
  • “Move my next post to Friday at 9am.”

Your assistant can't see your billing, your LinkedIn account or anything outside your queue.

Disconnect an assistant

Open Apps in PostHonk and click Disconnect next to it. Its access stops straight away. You can also remove PostHonk from the connectors or apps list in Claude or ChatGPT.

LinkedIn connection

PostHonk publishes with the permission you give when you sign in with LinkedIn. LinkedIn makes these connections expire every two months. We show a reminder a week before, and you reconnect with one click from the Posts page or Settings. If LinkedIn asks for a password you don't have (for example, you signed up to LinkedIn with Google), use “Forgot password” on LinkedIn's page to set one.

Trial, plans and cancelling

To schedule posts, start a 7-day free trial. You can do it from Billing, or when you add your first post. Nothing is charged until it ends. Change or cancel your plan in Billing at any time.

Delete your account

In Settings, choose Delete account. Your posts, schedule and connections are deleted and any plan is cancelled. See our privacy policy for details.
