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.
