Post to Instagram with Claude

Doing this yourself means a Meta developer app, the Instagram Graph API, app review, and a Facebook Page linkage before you publish a single photo. RobinReach is the one-connector fix: Claude plans the grid, writes the captions, generates the visuals, and schedules everything through one MCP URL.

  • No Instagram Graph API setup
  • No code, one MCP URL
  • Works with ChatGPT and Codex too
The DIY route

The Instagram Graph API was not built for humans

Instagram is one of the hardest platforms to publish to programmatically.

🏗️

Meta developer maze

You need a Meta developer app, app review, a Business or Creator account, and a linked Facebook Page just to unlock publishing endpoints.

🖼️

Media gymnastics

Images and videos must be hosted at public URLs, pushed through container creation and status polling, and every aspect ratio rule is your problem.

🚧

Format gaps

Each content type, from Reels to carousels to Stories, has its own endpoints, limits, and quirks that change with Meta's release notes.

Why the bridge matters

Why Claude can't post to Instagram on its own

Claude writes brilliant posts, but out of the box it has no account access, no publishing rights, and no scheduler. RobinReach's MCP server is the missing pair of hands.

Claude by itself

  • Cannot log in to Instagram or hold OAuth tokens for your account.
  • Cannot publish, schedule, or upload media. The draft dies in the chat window.
  • The workaround is the Instagram Graph API: developer registration, reviews, token refresh, and format rules, all maintained by you.
  • You end up as the copy-paste middleman for every single post.
The one-connector fix

Claude + RobinReach over MCP

  • RobinReach holds the official, compliant Instagram connection. You authorize it once with a normal OAuth click.
  • One MCP URL gives Claude real tools: draft, validate, attach media, schedule, and publish.
  • RobinReach handles tokens, rate limits, media processing, and Instagram's format rules for you.
  • The same connector covers all 13 RobinReach networks, so one setup unlocks every channel.

FAQ

Posting to Instagram with Claude, answered

How do I post to Instagram with Claude?
Create a free RobinReach account, connect your Instagram account with OAuth, and paste the RobinReach MCP URL into Claude under Settings, then Connectors. Click Connect and sign in to RobinReach. No API key needed. From there, ask Claude to create and schedule Instagram content and it publishes through RobinReach.

Why can't Claude post to Instagram by itself?
Claude has no access to your Instagram account and no publishing tools. Instagram also requires publishing to go through Meta's approved APIs. RobinReach holds that official integration and exposes it to Claude as MCP tools.

Can Claude publish Reels and carousels, not just photos?
Yes. RobinReach supports feed posts, carousels, Reels, and Stories, and Claude can create and schedule all of them. It validates aspect ratios and caption limits before anything is queued.

Do I need a Business account or a Facebook Page?
RobinReach guides you through connecting the right account type during its one-click OAuth setup. You never deal with Meta's developer portal, Graph API tokens, or app review yourself.

Will anything go live without my approval?
Only if you ask for that. Tell Claude to create drafts and everything lands on RobinReach's calendar for review, or use approval workflows so a teammate signs off before publishing.

Can Claude generate the images too?
Yes. RobinReach's generate_ai_image tool is available to Claude over MCP, so it can create branded visuals, carousel slides, and Reel covers as part of the same conversation.

Does this work with ChatGPT as well?
Yes. The same MCP URL plugs into ChatGPT with the same sign-in, through developer mode on a paid ChatGPT plan for now (ChatGPT app coming soon). OpenAI Codex works too, with an API key. Either way, you can run the identical workflow from whichever assistant you prefer.

Can I connect Claude to just one client's brand?
Yes. When you sign in to RobinReach, open "Or connect a single brand" and pick that client's brand. Claude can only reach that brand, and no API key changes hands. A client's brand admin can also connect their own brand themselves.
