LinkedIn is the one platform where the agent can also read and answer the comments, and the only one that takes a PDF as a post.
https://api.antwork.io/mcpClaude connects to Antwork as a custom connector: one URL pasted into the Add custom connector dialog, then a browser authorization. The same connector works in Claude Desktop once you are signed in.
Custom connectors need Claude Pro, Max, Team or Enterprise.
“Draft a LinkedIn post about what we shipped this week, in my voice, and show me before it goes out.”
“Turn this PDF into a LinkedIn carousel post and schedule it for Tuesday morning.”
“What did my last five LinkedIn posts do? Show me impressions and engagement.”
“Someone commented on my last post. Read the thread and draft a reply.”
Antwork does not answer with a wall of text. It renders real, clickable panels inside Claude — the same interface you would get in a dashboard, in the conversation you are already in. No other social tool does this.
Shipped something small this week that fixed a big thing. Our token refresh ran daily but checked LinkedIn against a five minute expiry window, so it could only ever catch a token that happened to die inside those five minutes. It never did. Accounts just went quiet.
LinkedIn is the only platform Antwork implements commenting for. The agent can read the thread under a published post and reply in the same voice it wrote the post in. On every other platform it publishes and stops.
LinkedIn accepts a document post — a PDF up to 100 MB that readers swipe through in the feed. Attach one and the agent posts it as a carousel. No other platform Antwork supports takes a document at all.
You can attach a document alongside images, but images and video can never share a post. Ask for both and the agent has to split them, so it will tell you before it drafts rather than after it fails.
Three thousand characters is roughly 500 words, and LinkedIn is the one place where using them is not a mistake. The agent drafts to the length the format rewards instead of trimming everything to a hook.
One command, one consent screen, and LinkedIn is something you can just ask for.
