Cursor is now available in the AI SDK harness layer Vercel's AI SDK harness layer now supports Cursor through the official @ai-sdk/harness-cursor adapter, enabling applications to run Cursor as a coding agent via the same HarnessAgent interface. The adapter connects through the Agent Client Protocol, joining existing supported harnesses including Claude Code, Cline, Codex, Deep Agents, Grok Build, OpenCode, and Pi. The AI SDK harness layer https://vercel.com/changelog/program-agent-harnesses-with-ai-sdk now supports Cursor through the official @ai-sdk/harness-cursor adapter. The harness layer lets your application run different coding agents through the same HarnessAgent interface, so you can switch agents without changing your application code. Pass cursor to HarnessAgent : Under the hood, the adapter uses @ai-sdk/harness-acp https://vercel.com/changelog/use-acp-compatible-harnesses-with-the-ai-sdk-harness-layer to connect Cursor to HarnessAgent through the Agent Client Protocol ACP . Supported harnesses now include, in addition to Cursor, Claude Code, Cline, Codex, Deep Agents, Grok Build, OpenCode, and Pi, with more coming soon.
