X makes it easy for AI assistants like Claude, Cursor, Grok Build, and other MCP-compatible apps to connect directly to the platform through new hosted MCP servers.
The Elon Musk-owned social network on Monday announced a hosted Model Context Protocol (MCP) server that allows AI tools to communicate with the X API using users’ own account privileges.
MCP is an open standard that defines a common way for AI models to connect to external tools and services. Previously, if a developer wanted an AI assistant like Claude or Cursor to access X, they had to build and host their own MCP server, connect to the X API, and handle authentication. Currently, X hosts the MCP and users authenticate with their X account privileges.
This allows developers to save time on integration efforts and focus on what they are actually building.
Developers have long been able to use the platform’s API to search for X, read posts, search for users, analyze conversations and trends, and more. Hosted MCP does not add any new functionality on that front. It just makes it easier to expose to AI applications. In doing so, X can position itself as an information network filled with real-time data to capture and analyze, rather than just a social hangout.
With this move, X joins the many companies that now offer their own official MCP servers or endpoints, including GitHub, Slack, Notion, Stripe, and Salesforce.
Of course, there’s always the concern that removing infrastructure hurdles will leave X open to more automated posting and spam.
It’s worth noting that hosted MCP does not bypass X’s API rules. If Company X detects spamming, its use will continue to be restricted.
X also updated its API v2 earlier this year to address the issue of AI-generated spam, specifically programmatic replies to conversations. Additionally, we recently updated our API pricing to increase the cost of publishing a post to $0.015 and the cost of posting a link to $0.20. Mr. X said at the time that the price increase was aimed at “curbing vectors of abuse.” That means, at the very least, it will be more expensive to send spam to X.
