How to post to LinkedIn from Claude Code

Set it up and post, step by step

Prompt to copy once LinkedIn is connected: Read CHANGELOG.md, write a LinkedIn post about what we shipped this week, show it to me, and schedule it for Tuesday at 8:30 my time.

1. Add PostWire to Claude Code

   In your terminal run claude mcp add --transport http postwire https://postwire.io/api/mcp (add --scope user to have it in every project), then type /mcp in Claude Code and pick postwire to sign in. The sign-in asks for your email and a 6-digit code, which also creates a free PostWire account if you have none: no password and no card.

2. Or install the LinkedIn skill instead

   npx skills add https://postwire.io --skill linkedin-post adds the skill to Claude Code (and to the other agents on the machine). It uses your key from the environment: copy it in the dashboard under API & MCP and set POSTWIRE_API_KEY. The skill is a plain file you can read first: linkedin-post/SKILL.md.

3. Connect your LinkedIn profile

   Ask "connect my LinkedIn". Claude Code calls create_connect_link and prints a 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, the hook in the first 210 characters (about two lines, what the feed shows before "see more"), short paragraphs, up to 3 hashtags at the end and a question to close. A link goes in the first comment, not in the body, where LinkedIn shows it less. Claude Code can read files in your repo for the facts, and you ask for changes in plain words.

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

   Up to 20 images in one post, or one PDF (or PowerPoint or Word file) on its own, which LinkedIn shows as a document you swipe through. Give Claude Code a public https link, or ask for an upload page (create_upload_link, valid 24 hours) and pick the files there.

6. Publish now, or schedule it

   Say "post it" and Claude Code 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, up to 365 days ahead, or with 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 CI time from 9 minutes to 2.\n\nThe fix was not a faster runner. …",
         "first_comment": "The full write-up: https://example.com/blog/ci-in-2-minutes"
       } },
       "run_at": "2026-10-20T08:30:00-05:00"
     }
   }

"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. Prefer to set it up by hand first? Open the dashboard, connect the account under Accounts and copy your key under API & MCP.
