A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

The primary manifest — the file an agent reads to learn what this artifact does.
An MCP server that scrapes public content from X (formerly Twitter) using a stealth Patchright browser, exposed over FastMCP. Designed to run with uvx, so any MCP client can launch it with zero local setup.
Inspired by stickerdaniel/linkedin-mcp-server.
Disclaimer: This is an independent, community project. It is not affiliated with, authorized by, endorsed by, or sponsored by X Corp. "X" and "Twitter" are trademarks of X Corp, used here only descriptively to identify the third-party service this software interoperates with.
X's official API is expensive and heavily gated. This server drives a real, undetected Chrome session via Patchright and reads the rendered page, so it works with a normal logged-in account. Selectors target X's stable data-testid attributes and will need occasional maintenance as the UI changes.
| Tool | Description |
|---|---|
get_profile(username) | Display name, bio, location, website, join date, follower/following counts. |
get_user_tweets(username, limit=20) | A user's most recent posts from their timeline. |
get_tweet(url_or_id) | A single post by URL or numeric status id. |
search_tweets(query, limit=20, latest=True) | Search across X; supports operators like from:, min_faves:, #tag. |
check_auth() | Diagnose whether the session is logged in. |
login(timeout_seconds=180) | Open a visible browser and sign in interactively; persists the session. |
login_with_credentials() | Best-effort automated DOM login from X_USERNAME/X_PASSWORD (no 2FA). |
post_tweet(text) | Publish a post from the logged-in account. |
reply_to_tweet(url_or_id, text) | Reply to an existing post. |
like_tweet(url_or_id) | Like a post. |
follow_user(username) | Follow a user from their profile. |
Handles may be passed as @name, name, or a full https://x.com/name URL. Write tools require an authenticated session (run login or set X_AUTH_TOKEN). See docs/RESEARCH.md for the reverse-engineered login/post HTTP flow behind a future browserless implementation.
The current scope is intentionally minimal: sign in and start posting. Everything below is a TODO, modelled on the capabilities of stickerdaniel/linkedin-mcp-server (the project that inspired this one) and adapted to X.
Near-term (the current focus)
login tool opens a browser for manual auth andpersists the session (run with X_HEADLESS=false). Cookie auth still works.
post_tweet(text) — publish a post from the logged-in account.Scaffolded but not yet validated against live X — selectors and the compose DOM drift. Verify with a real session before trusting output.
Write actions (X-native, inspired by `connect_with_person` / `send_message`)
reply_to_tweetquote_tweetlike_tweetrepostdelete_tweetfollow_userunfollowsend_dm, get_inbox, get_conversation, search_conversations(mirrors LinkedIn's messaging tools)
Read actions
get_my_profile — the authenticated user's own profile (get_my_profile).get_home_timeline — the logged-in home feed (get_feed).search_users — people search (search_people).get_who_to_follow — recommended accounts (get_sidebar_profiles).Session & tooling
close_session tool to terminate the browser and clean up..mcpb bundle.Most X content requires a logged-in session. Two options:
uv run mcp-server-x --loginThis opens a browser where you sign in manually (handles 2FA and challenges). The session is saved to X_USER_DATA_DIR (default: ~/.x-mcp/profile) and reused on all future runs — no cookie management needed.
Set environment variables in .env (copy from .env.example):
X_AUTH_TOKEN=... # the `auth_token` cookie from x.com
X_CSRF_TOKEN=... # the `ct0` cookie (optional but recommended)To grab them: log in to x.com, open DevTools → Application → Cookies → https://x.com, and copy auth_token and ct0.
uv run mcp-server-x --check-authuv run mcp-server-x --logoutPublished as mcp-server-x — uvx runs it without a local install:
# one-time interactive login (opens a browser, saves the session)
uvx mcp-server-x --login
# then run the server
uvx mcp-server-xPin a version for reproducibility, e.g. uvx [email protected].
To run an unreleased commit, point uvx at the repo instead:
uvx --from git+https://github.com/afikrim/x-mcp-server.git mcp-server-x --login
uvx --from git+https://github.com/afikrim/x-mcp-server.git mcp-server-xPin a tag or commit for reproducibility, e.g. git+https://github.com/afikrim/[email protected].
The Chromium browser is auto-provisioned on first launch if it isn't already present, so there's no separate patchright install step. (It downloads ~150MB once into the Patchright browser cache.)
--install writes the config for you, merging into the client's existing servers (it never clobbers other entries) and using each client's own CLI when available:
uvx mcp-server-x --install claude-desktop
uvx mcp-server-x --install claude-code
uvx mcp-server-x --install codex
uvx mcp-server-x --install opencode| Client | Config written |
|---|---|
claude-desktop | claude_desktop_config.json (platform-specific path) |
claude-code | claude mcp add-json (user scope), else ~/.claude.json |
codex | codex mcp add, else ~/.codex/config.toml |
opencode | ~/.config/opencode/opencode.json |
Restart the client afterward. Run --login once (see above) so the session exists before the client first calls a tool.
If you'd rather configure by hand:
{
"mcpServers": {
"mcp-server-x": {
"command": "uvx",
"args": ["mcp-server-x"]
}
}
}No env block is needed once you've run --login — the session is read from ~/.x-mcp/profile. (You can still pass X_AUTH_TOKEN / X_CSRF_TOKEN instead.)

Contributions welcome — see CONTRIBUTING.md for setup, conventions (notably: data-testid selectors only, browser-driven not API), and the current feature status.
This tool is for personal and research use only, and comes with no warranty of any kind. Use it in accordance with X's Terms of Service.
This server controls a real, logged-in browser session — it does not exploit undocumented APIs or bypass authentication. That said, X's Terms of Service prohibit scraping and automated access without prior consent, and accounts using automated tools can be rate-limited, restricted, or banned. There is no guarantee of account safety. Use at your own risk, and prefer an account you can afford to lose.
Because the session is authenticated, you have agreed to X's terms — so the risk here is contractual (breach of the ToS) and operational (account action), not just abstract. See the LinkedIn precedent (hiQ v. LinkedIn) for how courts have treated authenticated scraping versus public-data scraping.
You are responsible for the volume of automation you run. Use it sparingly, keep pacing human-like, respect rate limits, and prompt your agents responsibly. Do not redistribute, resell, or build public datasets from the output.
Use the official X API, or obtain written consent from X. The browser route is not defensible at scale — switch to a licensed path before you grow beyond personal use.
This project is directly inspired by stickerdaniel/linkedin-mcp-server by Daniel Sticker — a stealth-browser MCP server for LinkedIn. The architecture (Patchright + FastMCP, cookie/session auth, uvx distribution) and the Roadmap above follow its design. Go give it a star.
