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 in the Add custom connector dialog, then a sign-in on Antwork's own consent page. The same connector works in Claude Desktop once you are signed in.
Claude Pro, Max, Team, or Enterprise required. Custom connectors are not available on the free Claude plan.
Yes. Claude can post to LinkedIn through Antwork, a Model Context Protocol (MCP) connector. You paste one URL into Claude's Add custom connector dialog, approve LinkedIn once on LinkedIn's own OAuth screen, and from then on Claude drafts, schedules and publishes posts to your personal LinkedIn profile or to a Company Page you manage, from inside the conversation. Antwork calls LinkedIn's official API with the scopes you granted (w_member_social for your profile, w_organization_social for Company Pages), so there is no API key to generate, no browser extension to install, and no logged-in browser session being driven on your behalf.
Antwork is a publishing connector, not a prospecting one. It drafts, schedules and publishes posts, reads the engagement on posts you own, and replies to comments underneath them. It does not search or scrape profiles, enrich leads, send connection requests, or send direct messages.
LinkedIn MCP servers compared: which post through the official API, and which drive your browserChecked against the product on 3 October 2026Every screen is a real recording of claude.ai and Antwork, made on 26 September 2026. The chat list in the sidebar is blurred for privacy; only the cursor, zooms and captions are added.
Click Connect and we'll open Claude's Add custom connector dialog with the MCP URL copied to your clipboard. In claude.ai you can also get there yourself: Customize, then Connectors, then Add, then Add custom connector.
Anthropic does not publish a first-party LinkedIn connector, but Claude supports custom connectors over MCP and Antwork is one. You add it from Claude's own connector settings and its tools become available like any other: no browser extension, no API key, and no intermediate workflow to maintain. These are the approaches you are actually choosing between, and they differ in what each one leaves you holding.
“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.
