Twitterapi Io Mcp Server

twitterapi.io MCP Server

Official Model Context Protocol server for twitterapi.io — Twitter / X data API for AI agents and applications.

Connect Claude Desktop, Cursor, VS Code Copilot, or any MCP client to twitterapi.io and search tweets, fetch user profiles, get followers, replies, trends, and more — all from natural language.

Features

12 read-only tools mapped 1:1 to twitterapi.io's verified production endpoints:

Quick Start

1. Get an API key

Sign up at twitterapi.io — free tier available.

2. Configure your MCP client

Claude Desktop

Edit ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "twitterapi-io": {
      "command": "npx",
      "args": ["-y", "@twitterapi_io/mcp-server"],
      "env": {
        "TWITTERAPI_IO_API_KEY": "your_key_here"
      }
    }
  }
}

Restart Claude Desktop. The 12 tools will be available in any chat — Claude will pick the right one based on your prompt.

Cursor

Open Settings → MCP → Add new MCP Server:

{
  "mcpServers": {
    "twitterapi-io": {
      "command": "npx",
      "args": ["-y", "@twitterapi_io/mcp-server"],
      "env": {
        "TWITTERAPI_IO_API_KEY": "your_key_here"
      }
    }
  }
}

VS Code (Copilot Chat with MCP)

Add to your MCP servers config — same shape as Claude Desktop / Cursor.

Claude Code

claude mcp add twitterapi-io npx -- -y @twitterapi_io/mcp-server -e TWITTERAPI_IO_API_KEY=your_key_here

3. Use it

In any MCP-enabled chat:

"Find recent tweets from @elonmusk about AI in the last week"

"Get the follower list of @sama and show me the top 20 by follower count"

"What are the current trending topics in Japan?"

Claude (or your client) will automatically pick search_tweets / get_user_followers / get_trends and call them with the right parameters.

Authentication

Authentication is via the TWITTERAPI_IO_API_KEY environment variable, injected by your MCP client. The server never stores or logs the key. Each tool call sends the key in the X-API-Key header to https://api.twitterapi.io.

Pagination

Tools that return lists (followers, replies, search results, etc.) return a next_cursor field. Pass it back as the cursor argument on the next call to page through. Each page is typically ~20 items.

Error handling

• 429 / 5xx responses are automatically retried with exponential backoff (3 attempts, 1s/2s/4s)
• Network timeouts: 30s per request
• 4xx errors (other than 429) surface immediately to the LLM with the original message

Tools — full spec

Each tool's input schema is exposed via MCP's tools/list and follows JSON Schema. Run npx @twitterapi_io/mcp-server with mcp-inspector to browse interactively:

npx @modelcontextprotocol/inspector npx -y @twitterapi_io/mcp-server

What's NOT included

By design, this server exposes read-only endpoints. The following are intentionally excluded to keep the server safe for autonomous agent use:

• ❌ Posting tweets, likes, retweets, follows, DMs
• ❌ Account login / 2FA
• ❌ Profile / banner / avatar editing
• ❌ Media upload
• ❌ Account deletion
• ❌ Realtime stream / webhook setup (does not fit the MCP request/response model)

These features are available in the full twitterapi.io REST API — use it directly if you need write access.

Spec compliance

• Built on @modelcontextprotocol/sdk v1
• Targets MCP spec 2025-11-25 (latest)
• Transport: stdio (Streamable HTTP planned for v0.2+ for remote/hosted use)
• Tested with: mcp-inspector, Claude Desktop, Cursor, Claude Code

Development

git clone https://github.com/kaitoInfra/twitterapi-io-mcp-server.git
cd twitterapi-io-mcp-server
npm install
npm run build
TWITTERAPI_IO_API_KEY=xxx npm run inspect  # opens mcp-inspector
