Cursor ships Agent SDK to define agents in code and deploy with one command

Cursor released its Agent SDK, which lets teams define agents in code and deploy them to Cursor infrastructure with agent-sdk deploy. The framework handles events like pull requests, task handoffs and parallel sub-agents, and includes built-in evals and event replay. Prompts and tools go through version control and review. Agents can also run as a single Node process on your own infrastructure.

Why it matters: Cursor's Agent SDK turns prompts, tools and evals into a code project, so custom agents follow the same version control and review as other software.
