FAQ

What is MCP and why does X offering a hosted version matter?

MCP (Model Context Protocol) is an open standard that defines how AI models connect to external tools and services. Previously, developers had to build, host, and manage their own MCP server to let AI assistants access X; now X hosts it, saving developers integration work.

Which AI assistants can use X's new hosted MCP server?

The server works with MCP-compatible apps including Claude, Cursor, Grok Build, and other compatible applications.

How is X addressing spam concerns with easier AI access?

X updated its API v2 earlier this year to address AI-generated spam, and recently increased API posting costs to $0.015 per post and $0.20 per link. The hosted MCP continues to enforce X's existing API rules that restrict spammy behavior.
