AI SDK harness layer adds Cursor adapter for agent switching without code changes
↗
The AI SDK harness layer now supports Cursor through the official @ai-sdk/harness-cursor adapter, letting applications run Cursor alongside other coding agents through a unified HarnessAgent interface.
Teams can now swap between Cursor and eight other coding agents without rewriting integration code, reducing the cost of evaluating or replacing agents. The adapter uses the Agent Client Protocol (ACP), the same standardized connection layer other harness adapters rely on.

The @ai-sdk/harness-cursor adapter connects Cursor to the HarnessAgent interface via the Agent Client Protocol (ACP).
Applications using the harness layer can switch between Cursor and other supported agents without changing application code.
Supported harnesses now include Claude Code, Cline, Codex, Deep Agents, Grok Build, OpenCode, Pi, and Cursor, with more planned.
