🧩 xAI launches open plugin marketplace for Grok Build

The catalog is the public GitHub repository xai-org/plugin-marketplace: submissions via PR, plugins pinned to commit SHA. One package combines skills, slash commands, agents, hooks, MCP and LSP servers. At launch — MongoDB, Vercel, Sentry, Cloudflare and Superpowers.

🌍 Distribution of agent extensions is being standardized: Grok Build reads Claude Code formats without modification, and the MCP protocol has been transferred to Anthropic, Block and OpenAI under the Linux Foundation. The thesis “package — product” is the author's interpretation, not a market fact.

👤 Your skills in Claude Code or SKILL.md format are installed in Grok Build as is: storefront — /marketplace, installation — grok plugin install --trust. The license terms of the catalog are not quoted — check redistribution rights before submitting.
