How to post to LinkedIn from Claude, and schedule the posts

Set it up and post, step by step

Prompt to copy once LinkedIn is connected: Write a LinkedIn post about the three things we learned launching our pricing page, show it to me, and schedule it for Tuesday at 8:30 my time.

1. Add PostWire from Claude's directory

   Open PostWire in Claude's connector directory, press Connect, and check that PostWire is switched on in the chat's tools menu. It works in Claude on the web, the desktop app and the phone. In Claude Code, add it with claude mcp add --transport http postwire https://postwire.io/api/mcp.

2. Sign in with your email

   A 6-digit code creates your free PostWire account inside the sign-in window: no password and no card. If this browser is already signed in to PostWire, you choose the account.

3. Connect your LinkedIn profile

   Ask "connect my LinkedIn". Claude calls create_connect_link and gives you a one-hour link; open it, sign in on LinkedIn's own page and press Allow. PostWire asks LinkedIn only for permission to post as you (w_member_social), plus your name and photo to show which profile is connected.

4. Ask for the post

   "Write a LinkedIn post about the bug we fixed today." generate_posts returns a draft and publishes nothing. It is written for LinkedIn: first person, 1,200 to 1,500 characters when the idea allows, the hook in the first 210 characters (about two lines, what the feed shows before "see more"), very short blocks, 3 hashtags at the end. A link goes in the first comment, not in the body. Ask for changes in plain words until it reads right.

5. Add images or a PDF, if you want them

   Up to 20 images in one post, or one PDF, PowerPoint or Word file on its own, which LinkedIn shows as a document readers swipe through. A file attached to the chat does not reach a connector, so ask for an upload page (create_upload_link, up to 100 MB on the free plan and 1 GB on paid plans) and pick the files there, or give a public https link.

6. Publish now, or schedule it

   Say "post it" and Claude asks you to confirm, then calls post_to_social; the result carries the link to the live post and the first comment's status. Say "schedule it for Tuesday at 8:30" and it calls schedule_post, or uses run_at: "next_slot" for your next free posting hour. This is the call:

   {
     "name": "schedule_post",
     "arguments": {
       "platforms": ["linkedin"],
       "per_platform": { "linkedin": {
         "text": "We cut our onboarding from 9 steps to 3.\n\nThe fix was not a new design. …",
         "first_comment": "The full write-up: https://example.com/blog/onboarding-in-3-steps"
       } },
       "run_at": "2026-11-10T08:30:00-05:00"
     }
   }

7. Check the queue

   "What's scheduled on LinkedIn?" calls list_scheduled_posts and "cancel Tuesday's post" calls cancel_scheduled_post; the same queue is on the dashboard's Queue page.

Nothing is published before you say yes: Claude shows the exact text first and asks you to confirm. Prefer to set it up by hand? Open the dashboard, connect LinkedIn under Accounts and copy your key under API & MCP.
