# Post to X (Twitter) with Claude or ChatGPT (2026 Setup)

> To post to X (Twitter) with Claude, connect your X account to RobinReach, then add RobinReach to Claude as a connector at https://robinreach.com/mcp/v1/messages. Claude can then write posts and threads in your voice, keep each one within X's character limit, attach photos or a video, and schedule them, all from the chat. It can also read how your posts perform. X publishing and the AI integrations are both included from Bloom, and the same works in ChatGPT and other AI apps.

## Example

User: Turn our launch announcement into an X thread of four posts for Tuesday at 9, in our usual tone.

What Claude did in RobinReach:
- `style_learn`: Read how you usually write on X
- `posts_validate`: Checked every post in the thread against X's limit
- `posts_create`: Scheduled the thread for Tuesday at 09:00

Claude: Your four post thread goes out on Tuesday at 9. The first post carries the news and the link sits in the last reply, where it does not cut the opener short. Want a single post version for Threads and Bluesky?

## What Claude can do on X (Twitter)

- **Posts.** Short posts written to fit X's limit on the first try.
- **Threads.** A post with replies that go up right after it, written as one story.
- **Photos and GIFs.** Up to four images, or one video, per post.
- **Results.** Views and engagement for your recent posts, read back in the chat.

## Questions

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

Connect your X account 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 on X in plain words.

### Can Claude post threads on X?

Yes. Claude writes the first post and the replies, checks each one against X's limit and schedules them together, so the thread goes up in order.

### Which RobinReach plan do I need for X?

X publishing starts on Bloom, the same plan that includes the AI integrations. Each plan has a daily cap per X account, listed in the rules above.

### Do I need my own X API key?

No. RobinReach publishes through X's official API, so you only connect your X account once in RobinReach.

### Can ChatGPT post to X too?

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