# Post to Facebook with Claude or ChatGPT (2026 Setup)

> To post to Facebook with Claude, connect your Facebook Page to RobinReach, then add RobinReach to Claude as a connector at https://robinreach.com/mcp/v1/messages. Claude can then write and schedule Page posts, Reels and Stories, tag your location, add comments under a post, reply to and like comments, and set up Auto DM so people who comment a keyword get your link in Messenger. The same works in ChatGPT and other AI apps, on the Bloom, Thrive and Scale plans.

## Example

User: Post our weekend opening hours on the Page tomorrow at 8 and tag our location. When people comment HOURS, send them the booking link.

What Claude did in RobinReach:
- `account_locations`: Found your Page's address for the location tag
- `posts_validate`: Checked the post against Facebook's rules
- `posts_create`: Scheduled for tomorrow at 08:00 with your location
- `comment_automations_create`: People who comment HOURS get the booking link

Claude: All set. The post goes up tomorrow at 8 tagged at your shop, and anyone who comments HOURS gets a DM with the booking link and a button to open it. Want a short version for Instagram too?

## Questions

### How do I post to Facebook with Claude?

Connect your Facebook Page to RobinReach, add RobinReach to Claude as a custom connector with the URL https://robinreach.com/mcp/v1/messages and sign in. Then ask Claude to post or schedule in plain words.

### Can Claude post to my personal Facebook profile?

No. Facebook only lets apps publish to Pages, not personal profiles, so RobinReach connects Pages.

### Can Claude reply to Facebook comments?

Yes. It reads new comments from your Pages, replies in your voice and can like the kind ones. Replies are included from Bloom.

### What is Auto DM on Facebook?

An automation that sends a private message with your link to everyone who comments a keyword on your post. Claude can create, change and pause them for you.

### Can ChatGPT post to Facebook too?

Yes. Add RobinReach to ChatGPT as a custom MCP server and it gets the same tools.

### Will Claude publish without asking me?

RobinReach marks publishing right away and deleting so Claude confirms with you first, and Claude asks before tools that change things. You can also ask for drafts.
