Claude + LinkedIn
Post to LinkedIn with Claude
Claude posts to LinkedIn through Socialync's MCP server, which is included on the free plan with no card. Find Socialync in Claude's connector directory (or add https://mcp.socialync.io/mcp as a custom connector), sign in, and Claude can publish or schedule posts to your LinkedIn profile or Company Page once you say yes.
About five minutes the first time. Free plan, no card.
Five steps, once
- 1
Connect LinkedIn to Socialync
Create a free Socialync account (no card), open Settings, then Connections, and connect LinkedIn. After LinkedIn's sign in, Socialync lists your personal profile and the Company Pages you admin, and you pick the one this brand posts as.
- 2
Add the connector in Claude
Claude.ai: Settings, then Connectors, then Browse connectors, search Socialync, click Connect, sign in to Socialync, pick the brand. Adding https://mcp.socialync.io/mcp as a custom connector works too. Claude Code: one command, below. Claude Desktop and other clients: the connector guide has the setup.

Ask for the post
Paste your notes, a link or a rough idea and ask Claude for a LinkedIn post. Drop in up to 9 images if you want them.
- 4
Say yes, or give it a time
Claude checks the post against LinkedIn's limits and shows you the text, images, account and time. Say yes and it goes out now. Name a day and time and it goes into your Socialync calendar instead.

Check the queue
Ask Claude what is scheduled this week, or open the Socialync calendar. Both show the same queue. Change a time in the app, or ask Claude to cancel a post.

What Claude can do on LinkedIn through Socialync
Writing the post is the easy part. Claude also handles the account, the timing and the queue in the same conversation.
Text and image posts
Publish right away, or schedule up to 12 months ahead on paid plans and 2 on free. Up to 9 images in one post.
Your profile or your Page
Post as yourself or as a Company Page you admin. Each Socialync brand holds one LinkedIn account, and the post goes out as the one you connected.
Video, scheduled
Upload the video in Socialync, then ask Claude to schedule it. A video file cannot travel through a chat, and video is always scheduled.
Link in the first comment
Ask Claude to put your link or hashtags in a first comment. Socialync posts it under your LinkedIn post right after it goes live.
LinkedIn plus the rest
The same message can go to Threads, Bluesky, Facebook, X (paid plans) and Instagram (with an image), with its own caption on each platform. One publish counts as one post.
Queue control
List what is scheduled, cancel a post, or check whether yesterday's post went out and where.
Every post waits for your yes
Socialync tells Claude to show you the exact text, images, account and time before anything reaches LinkedIn, and to publish only after you confirm in the chat. Socialync also marks its publishing tools as destructive, so Claude asks your permission before it runs one. Every publish is logged with when you confirmed it.
To review in an app instead, ask Claude for a draft and approve it on your Socialync drafts page. A draft you do not approve expires after 24 hours.
Which Claude
Claude.ai
Settings, Connectors, Browse connectors, search Socialync, Connect. OAuth, no keys.
Claude Code
One command in the terminal, then /mcp to sign in in the browser. Handy when your launch notes and changelog live next to the code.
Claude Desktop
The connector guide has the setup, including a config file with an API key from your Socialync API Keys page.
Your own agent
Send a Socialync API key as a Bearer header. Same 22 tools, same rule: a person confirms every post.
Limits
- LinkedIn posts top out at 3,000 characters. Claude checks the length before it sends.
- LinkedIn has no API for Articles, so Claude writes a long post instead.
- Socialync does not collect LinkedIn post stats yet. Claude can pull numbers for TikTok, YouTube, Instagram, Facebook, Threads and Bluesky.
- Video is scheduled, never instant, because the platforms take minutes to process it.
- 5 AI-created posts a day per brand on free, 10 on paid, to stay under the networks' spam thresholds.
- Free plan: 5 posts a month, 2 months of scheduling. Paid from $20/month: unlimited posts, 12 months.
Frequently asked questions
Can Claude post to LinkedIn?
Yes, once it has a connector with LinkedIn publishing access. Socialync's MCP server is one. Posts go out through the LinkedIn account you connected with LinkedIn's own sign in, after Claude shows you the post and you say yes.
Can Claude post to my LinkedIn Company Page?
Yes, for a Page you admin. When you connect LinkedIn, Socialync lists your profile and your Pages and you pick one. Each Socialync brand holds one LinkedIn account, so to post as yourself and as your Page, connect the second one to another brand, allow both brands when you sign Claude in, and tell Claude which brand to post from. The free plan has 1 brand; paid plans include unlimited brands.
Can Claude schedule LinkedIn posts?
Yes. Tell Claude the day and time. Socialync holds the post and publishes it then, up to 12 months ahead on paid plans and 2 on free.
Does Claude need my LinkedIn password?
No. LinkedIn connects to Socialync through LinkedIn's own sign in, and Claude connects to Socialync through Socialync's sign in. Claude never sees a password, and you can remove its access any time from Connected apps in Socialync.
Can Claude tell me how my LinkedIn posts did?
Not yet. Socialync does not collect LinkedIn post stats today. It does for TikTok, YouTube, Instagram, Facebook, Threads and Bluesky, and Claude can read those.
Is it free?
Yes to start. The free plan is $0 with no card: 5 posts a calendar month, up to 5 connected accounts, 2 months of scheduling, and MCP included. Paid plans start at $20/month with unlimited posts and 12 months of scheduling.
Will Claude post without asking me?
No. Socialync tells Claude to show you the post and wait for your yes, and Claude asks your permission before it runs a publishing tool. You can also ask for a draft and approve it in the Socialync app.
Does this work in ChatGPT too?
Yes. It is the same server. The ChatGPT walkthrough has its own page.
