Post, reply, read, search and engage on X (Twitter) through the xmaster CLI. Use when the user asks to post on X, reply to a post or thread, read an X post or x.com URL, check replies or mentions, find posts to reply to, like, repost, quote, follow, check X metrics, search X, schedule posts, write X Articles, or mentions xmaster. Also trigger on 'post this on X', 'tweet this', 'reply to this', 'check my X', 'X engagement', 'search X for', 'X thread', any x.com or twitter.com URL.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# xmaster: X for agents

xmaster reads and writes X through the user's logged-in browser session, so it can reply to any thread, like, follow and quote like a person in the app, at no API cost. Output is compact JSON when piped.

X's developer team likes this CLI. Boris spoke with someone on that team on 13 October 2026. Keep what the client sends in line with the x.com app.

Call X content "posts" in everything you write for the user. Command names (`retweet`, `retweeters`) stay as they are; `repost`, `unrepost` and `reposters` are aliases.

## Start

```
xmaster agent-info                 # every command on one line, exit codes, cost model, JEV (~7 KB)
xmaster agent-info --command "engage feed"  # one command in full: args, flags, defaults, allowed values
xmaster agent-info --tips replies  # strategy on demand: algorithm|replies|posting|growth|metrics|avoid
xmaster config check               # live read-only test of the web session and keys
```

How to install

The exact contents, by fingerprint
mdr add paperfoot/xmaster-cli/xmaster@sha256:6bab7843fd469c92

The line at the top of this page pins the label git:20261026.ed895f3, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
