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

> To post to LinkedIn with Claude, connect your LinkedIn profile or company page to RobinReach, then add RobinReach to Claude as a connector at https://robinreach.com/mcp/v1/messages. Claude can then write a post in your voice, check it against LinkedIn's rules, attach photos, a video or a PDF document, add comments under it and schedule it, all from the chat. It can also read your LinkedIn numbers and answer comments. The same works in ChatGPT and other AI apps. RobinReach's AI integrations are included on the Bloom, Thrive and Scale plans.

## Example

User: Write a LinkedIn post about the biggest lesson from our Q3 launch, in my voice, and schedule it for Tuesday at 9. Add a comment under it with the three numbers.

What Claude did in RobinReach:
- `style_learn`: Read how you usually write on LinkedIn
- `account_profiles`: Found your profile and the company page
- `posts_validate`: Checked the length and the comment against LinkedIn's rules
- `posts_create`: Scheduled for Tuesday at 09:00 with one comment

Claude: Done. The post opens with the lesson, keeps your short paragraphs and ends with a question, and the three numbers go in the first comment. It is on your profile for Tuesday at 9. Want a version for the company page too?

## What Claude can do on LinkedIn

- **Text posts.** Long posts with a strong first line, short paragraphs and a question at the end, in the voice of your past posts.
- **Photos.** Several photos in one post, from your library, a public link or a new AI image.

## Questions

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

Connect LinkedIn to RobinReach, then add RobinReach to Claude as a custom connector with the URL https://robinreach.com/mcp/v1/messages and sign in. After that you ask in plain words, for example "schedule this for Tuesday at 9 on LinkedIn", and Claude does it through RobinReach.

### Can Claude post to my LinkedIn company page?

Yes. Connect your profile and any company pages you admin, and Claude can post to either or both, with a different text for each.

### Can ChatGPT post to LinkedIn too?

Yes. Add RobinReach to ChatGPT as a custom MCP server and it gets the same tools. Codex, Cursor, Gemini CLI and other MCP apps work as well.

### Will Claude post to LinkedIn without asking?

Claude asks before it runs tools that change things, and RobinReach marks publishing right away and deleting so Claude confirms with you. You can also ask for drafts and approve them on the RobinReach calendar.

### Do I need LinkedIn API access or code?

No. RobinReach publishes through LinkedIn's official API and keeps the connection up to date. You connect LinkedIn once in RobinReach and paste one URL into Claude.

### Can Claude see how my LinkedIn posts perform?

Yes. It can read reach and engagement per post, list your top posts and compare this week with last, then suggest what to post next.
