Cursor's Agent SDK turns custom agents into code projects you can test, then deploy anywhere.

◆Current state
Cursor has grown from an editor into a delivery platform: Projects coordinates cloud agents, Origin hosts repos with a 20+ app marketplace, Rollouts watches deploys, and the Environments API scripts agent sandboxes. On October 20 the Agent SDK went GA. An agent is now a folder with a prompt, typed tools, skills, MCP connections and channels, tested with evals and deployed either to Cursor or to the team's own infrastructure.
◆Where it's heading
The last month has been about opening Cursor's agent stack to outside code: partner apps write into Origin, the Environments API exposes sandboxes, and the Agent SDK lets teams build their own bots on the same runtime. Agents that wake on PR, CI, Slack, webhook and cron events push Cursor past the IDE into always-on team automation. Cursor is selling the agent runtime itself, not just its own agents.
◆Prediction
Expect more starter templates and SDK-built agents to appear in the app marketplace, and tighter links between SDK agents and Projects or Rollouts. Whether self-hosted deploys get the same dashboard tooling as Cursor-hosted ones is not yet clear from the entries.

    Cursor Agent SDK goes GA: agents as code, deployable anywhere

    ⚡ SPARK

    The Agent SDK is the developer-facing layer on top of the cloud agent stack Cursor built through September and October. After exposing environments by API and partner apps in Origin, Cursor now lets teams define, test and host their own agents on the same runtime.

    # Canvases from cloud agents

    Three additions to the cloud agent layer: agents can produce shareable interactive canvases, an Environments API in beta makes agent sandboxes scriptable, and environments scale to 300 repositories with 5x faster loads for large ones. It extends the platform-API direction set by the Origin marketplace three days earlier, aimed at larger engineering organizations.

    Origin App Marketplace opens with 20+ apps and public submissions

    ⚡ SPARK

    Origin launched in August with repos, PRs and GitHub sync; this release adds the ecosystem layer a code host needs before teams can move off GitHub. With CI, deploy, security and monitoring vendors wired in, the delivery loop Cursor has been assembling now spans tools it doesn't build.

    # Rollouts

    ⚡ SPARK

    Rollouts closes the last gap in Cursor's agentic delivery loop: production observability. The monitor writes a risk-and-signal plan when a PR opens, tracks the change per environment during deploy, and flags regressions by name — the first time Cursor has eyes on what happens after an agent ships code. Security Review ships in the same release and posts one comment per PR with exploitable bugs, attack paths, and proposed fixes.

    # Powered by Cloud Agents

    ⚡ SPARK

    Projects formalizes the coordinator-subagent pattern that was implicit in earlier cloud agent releases. The coordinator never writes code itself — it plans, delegates to subagents running in parallel, and brings results back for review. Shared context that persists across agents and sessions is the architectural bet: each agent builds on what the last one learned, so the workspace gets more effective over time.

    Self-hosted pools, external sandboxes, and Linux/Mac computer use

    ⚡ SPARK

    Self-hosted machine pools gained dynamic capacity scaling and integrations with eight external sandbox providers — AWS Lambda, Modal, Vercel, Daytona, and others. Agents no longer need dedicated warm machines; pools scale on demand and can hibernate idle workers. Computer use on Linux and Mac extends the self-hosted surface to full desktop automation, including browser control.
