Ask for Bluesky posts and threads
Tell Claude Code what to post on Bluesky and when. Everything it schedules shows up in your Postbase calendar.
claude mcp add --transport http postbase https://mcp.postbase.so/mcpWhat to ask Claude Code
A few Bluesky requests that work well.
“Write a Bluesky post for the release, under 300 characters, and schedule it with the X post.”
“Turn the top three items in CHANGELOG.md into a 3-post Bluesky thread.”
“List what's scheduled on Bluesky for launch week.”
How Claude Code's posts work on Bluesky
- Length
- 300 characters per post, counted the way you'd count them by eye.
- Links
- Bluesky doesn't make links clickable on its own. Postbase does it for you when the post goes out.
- Threads
- Ask for a thread and each post is published as a reply to the one before, in order.
Tips for better Bluesky posts
- Bluesky is a little more casual than LinkedIn. Tell the agent the tone you want.
- Ask for one version for X and one for Bluesky rather than sharing text: the limits differ (280 vs 300).
- Keep links at the end of a post so the preview reads well.
Frequently asked questions
Do links in the agent's posts work on Bluesky?
Yes. Postbase adds the link markup Bluesky needs when it publishes, so links are clickable.
Can it post the same thing to X and Bluesky?
Yes. It can send one post to both channels, or a separate version to each. Separate versions usually read better.
Does Claude Code need my Bluesky password?
No. You connect Bluesky to Postbase once, and Claude Code signs in to Postbase, not to Bluesky. You can revoke Claude Code's access from the Developers page at any time.
Can Claude Code delete my Bluesky posts?
No. It can list channels, create drafts and scheduled posts, list the queue and cancel a scheduled post. There's no tool for deleting anything.
