fx is now available in the AI SDK harness layer (Vercel)

blog post · Story page

Vercel's AI SDK harness layer added fx, its open-source coding agent, through an adapter speaking the Agent Client Protocol. fx joins Claude Code, Codex, Cursor, and the other supported harnesses behind one HarnessAgent API.

In plain words

  • Vercel added its open-source fx coding assistant to software that lets applications run several such assistants through one connection.
  • An official connector links fx to the shared system, so developers do not need a separate connection.
  • Teams already using Vercel's shared system can add fx without building a separate connection.
