@ai-sdk/harness-cursor connects Cursor to the HarnessAgent interface through @ai-sdk/harness-acp over the Agent Client Protocol (Vercel). Instantiating is two lines and swapping the harness value changes which agent runs without touching application code. Coverage now spans Claude Code, Cline, Codex, Cursor, Deep Agents, Grok Build, OpenCode and Pi, which makes ACP the practical portability layer if you're embedding an agent in your own product.
