What you need before you start
Add the connector from the connectors directory and sign in to the workspace that owns the social accounts.
You must be authorized to connect and publish to the selected X account.
Bring the facts, intended audience, voice, link, call to action, and any supported media you want included.
SocialRainbow requires approval of the exact validated preview before it creates a publication.
How to post to X from Claude
- Add SocialRainbow to Claude
Start the SocialRainbow trial, then open the connectors directory, find SocialRainbow, choose Connect, and sign in with the same SocialRainbow account.
- Connect your X account
Choose the X connection and complete the provider's authorization page. Return to Claude and list accounts again to confirm the connection.
- Draft for X
Keep one sharp idea per post and remove throat-clearing. Use a thread only when the idea truly needs ordered steps. Include any intended link or supported media before validation.
- Validate and review the exact preview
Check every destination, the visible post text, link behavior, media, follow-ups, and platform options. Resolve warnings or errors before approval.
- Approve and publish
Explicitly approve that exact preview. SocialRainbow publishes the unchanged payload and returns the actual publication job status.
A prompt you can copy
You do not need to name internal tools. State the outcome, destinations, source material, and approval requirement in plain language.

Media handling in Claude
For media posts, provide a direct public media URL that SocialRainbow can validate for the selected destination.
Media storage does not publish a post. The assistant still has to validate the destination, show the complete preview, receive approval, and call the final publish or schedule action.
What the final review should show
- The exact connected account name and destination.
- The final visible root post and any follow-ups or comments.
- Every link, media item, and destination-specific option.
- Warnings, normalization changes, or validation errors.
If anything changes after that review, validate the new version and approve it again. This keeps the user's approval tied to the content that will actually be sent.
