A Twitter/X integration for AI agents that provides tools for reading, searching, posting, and managing account activity. Twitter/X is the social network formerly known as Twitter.

Use it to post tweets or threads, upload media, read users’ tweets, search content, manage likes and bookmarks, check notifications, and update profile details.

It lets an agent work with Twitter/X through configured tools instead of requiring separate manual browser actions for each task.

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add checkra1neth/xbird-skill --skill xbird

Clone the repo

git clone --depth 1 https://github.com/checkra1neth/xbird-skill

Made for: Claude Code.

Or install xbird, the plugin that ships this one along with the rest of its 4 skills.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00078	$0.00735
Opus 5.5	$0.00031	$0.00294
Sonnet 5.5	$0.00016	$0.00147
Haiku 4.5	$0.00008	$0.00073

Measured 2mo ago against content hash e984b28c439e, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

xbird scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

xbird — Twitter/X for AI Agents

247 MCP tools for Twitter/X with x402 micropayments. Pure Node.js — no Bun required.

Zero config — auto-detects your browser session and generates a wallet. No API keys, no developer account.

When to Use

Running inside Claude Code, Cursor, or Windsurf
Need direct MCP tool access to Twitter/X
Works with Node.js >= 18 — no Bun required

Don't use when: Building backend services or autonomous agents (use REST x402 instead), or operating on Virtuals marketplace (use ACP instead).

Setup

Two runtime options:

Bun (recommended) — zero config

claude mcp add xbird -- bunx @checkra1n/xbird

Auto-detects cookies from Chrome, Firefox, Edge, Safari. Just log in to x.com — done.

Node.js — one-time login

claude mcp add xbird -- npx @checkra1n/xbird
npx @checkra1n/xbird login  # paste auth_token + ct0 from x.com DevTools

A payment wallet is generated automatically on first run.

Full tool list: see tools.md.

Common Workflows

Post tweet with image: upload_media (get mediaId) → post_tweet with mediaIds: ["<id>"]

Get someone's tweets: get_user (get numeric userId) → get_user_tweets with userId

Search and engage: search_tweets with query → like_tweet or retweet results

Update profile: update_profile_image + update_profile with new bio

Quick Reference

Handles:    work with or without @ prefix
Pagination: most tools accept cursor; list/search use count (default 20, max 100)
Media:      always upload first, then attach mediaId to tweet
Billing:    resource × count — post_read $0.0025 | user_read $0.005 | owned_read $0.001
              post_create $0.0075 | interaction_create $0.0075 | content_create $0.005

Common Mistakes

Mistake	Fix
Using handle for bulk tools	`get_user_tweets`, `get_followers`, etc. need numeric `userId`. Call `get_user` first.
Posting thread with 1 tweet	`post_thread` requires minimum 2 tweets. Use `post_tweet` for single tweet.
Media not attached	Upload returns `mediaId` — must pass it in `mediaIds` array to `post_tweet`.
Rate limit error	Twitter rate limit. Wait 1-2 minutes, retry.
Cookies not detected	Run `npx @checkra1n/xbird login` and paste cookies manually. Auto-detect only works with Bun, not npx.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
