Can Claude post to Instagram?
Yes, through a connector.
Claude can post to Instagram through Antwork, a Model Context Protocol (MCP) connector. You add Antwork's server URL as a custom connector in Claude, connect your Instagram professional account (Business or Creator) once on Instagram's own login screen, and from then on Claude writes captions, schedules and publishes posts, carousels and Reels from inside the conversation. Antwork uses Instagram's official publishing API with the permissions you granted, so there is no password to share, no API key to paste and no browser extension driving your logged-in Instagram.
- Business or Creator accountInstagram lets apps publish only to professional accounts. Switching is free.
- Posts, carousels and ReelsPhotos and video, mixed in one carousel if you like.
- You approve every postDrafting and publishing are separate steps. Nothing goes out until you say so.
Connect Claude to Instagram in 4 steps
About two minutes, on a computer or in claude.ai in your phone browser. Works on every Claude plan, Free included. The Free plan allows one custom connector. If another one already uses it, remove that one first.
- 1Step 1 of 4Open the connector dialogClick 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.
- 2Step 2 of 4Name it and paste the URLEnter the Name, paste the URL into MCP server URL, and click Continue. On the next screen keep the options Claude detects, Sign in now and Register automatically, and click Add.https://api.antwork.io/mcp
- 3Step 3 of 4Authorize in AntworkSign in to Antwork and approve the permissions. Claude then lists Antwork's tools, set to ask before each use. The same connector works in Claude Desktop once you're signed in. Then ask Claude to connect your Instagram.
- 4Step 4 of 4Ask for a postTell Claude what you want to post. It reads your recent posts first, drafts in your voice, and shows you exactly what it will save before it does. Drafts land in Antwork; nothing is scheduled or published until you say so.“Write an Instagram caption for this photo in my usual voice.”
On your phone? Add the connector once in claude.ai in your browser, not in the Claude app. After that it is there in the Claude app too.
Things to ask Claude once it is connected
Copy one into Claude to try it. Claude always shows you the post before anything is scheduled or published.
What Instagram accepts
Claude checks these before it drafts, so a post does not fail at publish time. They come from the same rules Antwork's publisher enforces.
- Account
- Business or Creator account
- Instagram needs a professional account (Business or Creator). Personal accounts cannot connect, but switching is free: in the Instagram app, Settings, then Account type and tools, then Switch to professional account, then Creator.

An automation tool is the better fit when a post should be triggered by something outside the chat, like a new row in a spreadsheet. If you want to ask Claude and see the post, the connector is the shortest path.

Claude and Instagram, answered
Can Claude connect to Instagram?
Yes. Antwork is the connector: you add one URL to Claude, approve Instagram once over OAuth, and from then on Claude drafts, schedules and publishes to your account from the chat itself. No API key, no browser extension, no copying between tabs.
Is there a native Claude connector for Instagram?
Claude does not post to Instagram on its own, and Anthropic does not ship an Instagram connector. Claude supports custom connectors over MCP, and Antwork is one built for publishing: you add it from Claude's connector settings and its tools appear like any other, with no browser extension and no API key.
Can Claude AI access Instagram?
Not on its own. Claude has no built-in Instagram access; it reaches Instagram through a connector you add. With Antwork connected, Claude can publish to your Instagram professional account and read how your own posts performed. It cannot browse Instagram, see other accounts or open your direct messages.
How do I set up Claude for Instagram?
Add Antwork as a custom connector in Claude (Customize, then Connectors, then Add custom connector, and paste the server URL), sign in to Antwork, then ask Claude to connect Instagram. Instagram's own login screen opens; approve it with your Business or Creator account and Claude can draft and post from then on. The free Claude plan allows one custom connector.
Can Claude post to social media?
Yes, through a connector. With Antwork, Claude publishes to Instagram, LinkedIn, X, Threads, TikTok, YouTube, Facebook and Pinterest from the same conversation, each account connected once over that platform's own OAuth. Drafting and publishing are separate steps, so nothing goes out until you say so.
Can I connect a personal Instagram account?
No. Instagram only lets third-party apps publish to professional accounts, Business or Creator. Switching an account to Creator is free and done in Instagram's own settings.
How is this different from Zapier, n8n or an integration toolkit?
What drives the action. In a workflow builder, Claude is a node inside an automation you maintain. With Antwork, drafting, scheduling and publishing to Instagram are tools Claude operates directly in the conversation, and the platform's limits are enforced server-side rather than being whatever the flow happens to carry.
Do I need an API key to connect Claude?
No. Antwork connects over OAuth — you approve a consent screen in the browser and you are done. There is no key to generate or paste into a URL, which is how most social MCP servers handle it.
Do I need a paid account?
No. Your first two connected accounts are free forever, with unlimited posts and workspaces, and there is no plan gate on MCP access.
Will Claude post without showing me first?
Not unless you ask it to. Drafting and publishing are two separate steps: the agent writes, renders the post card, and only publishes when you confirm.
Does the writing sound like AI?
Antwork hands the agent that account's recent posts, along with how each performed, and the agent writes to match them. On Instagram that includes writing to the length the format rewards, up to 2,200 characters.
