Create a new post on Bluesky
LABSCO SUMMARY
Every action that changes your account has its reversal sitting next to it.
Like and unlike, repost and unrepost, create and delete — the pairing means an assistant acting on your behalf can undo its own work without a separate cleanup path. The reversals take the URI produced when the action happened, so those URIs are the thing worth holding on to. Reading stays separate from writing: the timeline comes back under a limit you set, and posts can be pulled one at a time or several at once by URI.
What it is
A Bluesky client covering posting, timeline reading and the interactions that can be taken back.
What you get
- Login from the configured credentials, or with an identifier and password passed in at call time.
- Posts created with text and images, and deleted by URI.
- Your own profile, and your timeline with a limit you set.
- One post by URI, or several posts by their URIs in a single call.
- Likes and reposts, each paired with the call that removes it.
Requirements
A Bluesky account, with the identifier in BLUESKY_IDENTIFIER and the password in BLUESKY_PASSWORD.
Setup effort
One command plus credentials — npx -y @semihberkay/bluesky-mcp, then supply credentials
USE CASES
01
Publishing a post with an image from the assistant
Authentication comes first, from the configured credentials or from ones passed in, and the post carries text and images together.
02
Taking back something posted or reacted to on your account
Each reversal takes the URI produced by the original action, so undoing is a lookup rather than a search.
03
Catching up on the timeline and responding to it
The timeline arrives under a limit you set, and posts can be pulled individually or in a batch before anything is liked or reposted.
