A wave of Grok Bots is connecting to X—Elon Musk is letting AI post online by itself now Grok Bots can now link to users' X accounts, use MCP to call the X API, and post content autonomously. X is even planning to provide free developer API credits for this MCP system. Posts generated by Grok Bots will come with an AI-generated tag. What xAI is testing isn’t just AI helping you write a tweet—it’s giving AI full control over social network operations: it works, it posts, and humans only handle the authorization. X has made it clear that more Bots will gradually be allowed to participate in the future, but their bot identities will be clearly labeled.
