TL;DR
Creator Mike Russell live-streams the end-to-end setup of X's official MCP server, showing exactly how to connect AI agents like Grok and Claude Code directly to the X platform API. Despite hitting numerous real-world obstacles — port conflicts, OAuth failures, wrong app permissions, and depleted API credits — he eventually gets it working and demonstrates live searches, profile research, and automated posting via the XMCP.
Key points
1
X (Twitter) has launched an official MCP server at api.x.com/mcp, giving AI agents like Claude and Grok direct programmatic access to X without web scraping or custom API integrations
2
Setup requires installing xcurl (X's first-party CLI tool), creating an app in the X Developer Console with read/write OAuth 2.0 permissions, and adding the MCP config to your AI agent (e.g. Grok Build or Claude Code)
3
The XMCP exposes 200+ tools including post search, full archive search, user lookup, timeline reading, bookmarks, trending news by location, and article drafting/publishing
4
Real-world setup is significantly harder than edited tutorials suggest — common blockers include port 8080 conflicts, apps needing to be inside a project, read-only vs read/write permission mismatches, and depleted API credits
5
Once connected, the XMCP can autonomously research your X profile, find strategic engagement targets (similar accounts), generate images with Grok, and post content directly to X
Actionable insights
→
Install xcurl via Homebrew first, then create your X Developer app inside a project (not as a standalone free-tier app) and set permissions to read/write — skipping either step causes the OAuth flow to fail
→
When adding the XMCP to Grok Build, run the command with your OAuth 2 keys, then type /mcps inside Grok Build to confirm the X API is initializing; if OAuth hangs, check whether port 8080 is already in use by another process
→
For business use, prompt the XMCP to research your own X profile and surface strategic engagement twins — it can cross-reference who you follow, your bio, and your post history to identify Tier 1/2/3 network partners worth engaging
→
API credit balance on your X developer account is separate from your X subscription — you need to top up credits in the developer dashboard before write operations (like media posting) will succeed
Notable quotes
“Nothing in the world of AI is as easy as a 10-minute edited video on a YouTube channel.”
“X is zagging while the other platforms are zigging and I love X for this.”
“256 GB is minimum if you want AI that's not a toy.”
