@twitterapis/mcp

Official Model Context Protocol server for twitterapis.com, the Twitter / X API as native tools for Claude, Cursor, Windsurf, and any MCP client. Reads (search, profiles, timelines, followers, DMs) plus write actions (post, like, retweet, follow).

Ask your agent to search tweets, pull a user's profile or timeline, list followers/following, fetch thread context, or enumerate list members and it calls the API directly. Every tool maps to a REST endpoint at https://api.twitterapis.com; the server holds no state and forwards your API key on each call.

Quick start

No install needed. Run with npx. You need one thing: an API key (free $0.50 in credits, no card required): twitterapis.com/signup.

Setup

Claude Desktop

Edit claude_desktop_config.json (Settings → Developer → Edit Config):

{
  "mcpServers": {
    "twitterapis": {
      "command": "npx",
      "args": ["-y", "@twitterapis/mcp@latest"],
      "env": { "TWITTERAPIS_KEY": "YOUR_API_KEY" }
    }
  }
}

Restart Claude Desktop. The twitter_* tools appear in the tool picker.

Cursor

~/.cursor/mcp.json (or Settings → MCP → Add New Server):

{
  "mcpServers": {
    "twitterapis": {
      "command": "npx",
      "args": ["-y", "@twitterapis/mcp@latest"],
      "env": { "TWITTERAPIS_KEY": "YOUR_API_KEY" }
    }
  }
}

Windsurf

~/.codeium/windsurf/mcp_config.json:

{
  "mcpServers": {
    "twitterapis": {
      "command": "npx",
      "args": ["-y", "@twitterapis/mcp@latest"],
      "env": { "TWITTERAPIS_KEY": "YOUR_API_KEY" }
    }
  }
}

VS Code (Copilot / agent mode)

.vscode/mcp.json in your workspace, or the user-level MCP settings:

{
  "servers": {
    "twitterapis": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "@twitterapis/mcp@latest"],
      "env": { "TWITTERAPIS_KEY": "YOUR_API_KEY" }
    }
  }
}

Configuration

Tools

51 tools: 37 reads and 14 write actions. Most user endpoints accept username (handle without @) or user_id (twitter_user_likes and twitter_user_tweets_complete require user_id); tweet endpoints accept id or url; paginated endpoints return a cursor you pass back to get the next page. Two of the reads are free account/billing lookups (twitter_account_me, twitter_account_payments).

Public reads (search, profiles, tweets, followers, likes) work with just your API key. The account-only reads (bookmarks, DMs, home timeline, followers-you-know) and all write actions act AS an authenticated X account, so they need a session linked to your key first (returns HTTP 409 until then). Link a session either by registering your x.com cookies (twitter_customer_session) or by logging in with a username/password (twitter_user_login). Alternatively, pass per-call inline credentials on any of those tools (auth_token + ct0, with optional proxy_url / user_agent) to act AS that account for a single call without pre-registering a session, so one API key can act as many accounts. For write actions, set proxy_url to a residential proxy, since X soft-blocks writes that egress from datacenter IPs. Each write tool is annotated readOnlyHint: false; reversing actions (delete, unfollow, unlike, unretweet, unbookmark) are annotated destructiveHint: true so MCP clients can prompt before running them.

Reads

Write actions (require a linked X session)

Session setup

Link an X account to your key once, so the account-only reads and write actions act as it (or pass per-call auth_token/ct0 instead).

Usage examples

Search for trending AI tweets

"Find the most popular tweets about AI agents posted this week"

The agent calls twitter_advanced_search with:

query: "AI agents min_faves:200 since:2024-01-01"
product: "Top"
count: 20

Pull a user's recent posts

"Get the last 10 tweets from @sama"

The agent calls twitter_user_tweets with:

username: "sama"
count: 10

Read a full thread

"Get the full thread for this tweet: https://x.com/karpathy/status/1849....."

The agent calls twitter_tweet_thread with:

url: "https://x.com/karpathy/status/1849....."

Paginate through followers

"List the first 100 followers of @openai, then the next 100"

First call, twitter_user_followers: { username: "openai", count: 100 } Second call, pass back the cursor from the first response: { username: "openai", count: 100, cursor: "<cursor from response>" }

Monitor brand mentions

"Show me recent tweets mentioning @twitterapis"

The agent calls twitter_user_mentions with:

username: "twitterapis"
count: 50

Troubleshooting

HTTP 401 (invalid or missing API key) Check that TWITTERAPIS_KEY is set correctly in your MCP client config and matches the key shown in your dashboard.

HTTP 402 (insufficient credits) Top up at twitterapis.com/dashboard. Your first $0.50 is free at signup.

HTTP 403 (access forbidden) The account or tweet may be private/protected, or your plan does not include this endpoint.

HTTP 404 (not found) The user, tweet, or list may have been deleted, suspended, or the id/handle is wrong.

HTTP 429 (rate limited) Wait a few seconds and retry. If you hit this frequently, add "TWITTERAPIS_TIMEOUT_MS": "60000" to your env config and space out bulk requests.

Request failed: timed out after 30000ms The default timeout is 30 s. For large paginated fetches set TWITTERAPIS_TIMEOUT_MS to a higher value (e.g. 60000).

Tools do not appear in Claude / Cursor Ensure npx is on your PATH and Node.js 18+ is installed (node --version). Check MCP client logs for startup errors.

Pricing

Calls are billed to your twitterapis.com account. Almost every endpoint is $0.0008/call: all reads (search, profiles, tweets, followers, likes) plus the simple write actions (like, retweet, bookmark, follow and their undos, delete). At the read rate that works out to $0.04 per 1,000 tweets, since each call returns about 20 tweets. The premium endpoints cost a little more: tweet creation, sending a DM (twitter_dm_send), and DM reads (twitter_dm_list, twitter_dm_conversation) at $0.0016/call, full tweet history (twitter_user_tweets_complete) at $0.0024/call, and a full tweet thread (twitter_tweet_thread) at $0.004/call. Your first $0.50 is free. See twitterapis.com/pricing.

FAQ

Do I need an X (Twitter) developer account? No. Get an API key at twitterapis.com/signup; there is no application or approval step.

Is it read-only? No. 37 read tools work with just your API key; 14 write actions (post, like, retweet, follow, DM, media upload) act as a linked X account or per-call inline credentials.

Which clients are supported? Claude Desktop, Cursor, Windsurf, and VS Code (Copilot agent mode), or any Model Context Protocol client.

How is it billed? Per request. New keys start with $0.50 in free credits, no card required. See pricing.

Does it store my key or data? No. The server holds no state and forwards your API key on each call.

Maintainers

src/tools.js is generated. Do not edit it. The catalog is built at build time from two committed inputs:

• test/openapi.snapshot.json, a vendored copy of the published OpenAPI spec, which supplies the structure: which endpoints exist, which parameters each accepts, whether a parameter is required, and its type.
• scripts/tools.overrides.mjs, hand-authored, which supplies everything the spec cannot express: the tool and argument descriptions a model reads to decide how to call a tool, the cross-field rules ("provide exactly one of username or user_id"), the per-call credential arguments that travel as x-* headers, and the write / destructive / JSON-body flags.

The spec is vendored on purpose. Nothing is fetched at install time or at server boot, so the published package is a fixed artifact rather than one that depends on a hostname still answering.

npm run openapi:refresh   # re-vendor the spec, prints the route diff
npm run build             # regenerate src/tools.js
npm test                  # gates, incl. "src/tools.js matches the generator"

npm test fails if src/tools.js was hand-edited or left stale, if the catalog and the live spec disagree, or if the tool list and this README disagree.
