X (Twitter) Official MCP Complete Guide 2026: Automate Search, Posting & Trend Fetching with AI Agents

「If only I could operate X data directly from an AI agent…」

In 2026, X (formerly Twitter) released an official MCP (Model Context Protocol) server. Now AI tools like Grok Build, Cursor, Claude Desktop, and VS Code can call the X API directly.

First: What Is MCP? In 3 Lines

MCP (Model Context Protocol) is a standard protocol connecting AI agents and external services.

An analogy:

USB-C = any device connects with the same cable (standardization)
MCP = any AI tool connects to external services the same way (standardization)

Previously you needed separate X plugins for Cursor, Claude, etc. With MCP, one config works across all AI tools.

X MCP Overview: 2 Servers

X officially provides 2 free MCP servers.

Server	Role	URL	Auth
Search & Trends MCP	Search posts, get trends, user info	https://api.x.com/mcp	Bearer token
Post & DM MCP	Create posts, send DMs	https://api.x.com/mcp/post	OAuth 2.0 (xurl bridge)

Setup: Route 1 (Read-Only: Search & Trends)

1. Get a Bearer Token

Create an app in the X Developer Portal and get a Bearer token.

2. Add MCP to Your Tool

Example (VS Code / Claude Desktop):

{
  "url": "https://api.x.com/mcp",
  "headers": {
    "Authorization": "Bearer YOUR_BEARER_TOKEN"
  }
}

3. Done

Ask your AI: "Search for the latest posts about DeepSeek" — it queries X via MCP.

Setup: Route 2 (Post & DM with xurl)

For posting, use the xurl OAuth bridge:

# Install xurl
npm install -g @xdevplatform/xurl

# Authenticate with your X account
xurl login

Then add the MCP server:

{
  "url": "https://api.x.com/mcp/post",
  "headers": {
    "Authorization": "Bearer YOUR_BEARER_TOKEN"
  }
}

What You Can Do (Examples)

Search posts: "Find posts mentioning #AI agents in the last hour"
Get trends: "What are today's trending topics in Japan?"
Post: "Post: Just launched our new product! 🚀"
Send DMs: "DM @username our pricing page"
User research: "Get info on @nousresearch"

Practical Prompts

Use X MCP to search for the top 10 posts about "local AI" from the last 24 hours,
and summarize the main sentiment.

Get today's worldwide trends, filter to tech-related ones,
and suggest which to write a blog post about.
