## AI overview

The AI SDK harness layer adds official Cursor support through an adapter. Applications can run Cursor and other coding agents through the shared HarnessAgent interface without changing application code.

## Source excerpt

The AI SDK harness layer 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 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.
