Cursor Releases Agent SDK for Custom Development Workflows

Cursor launched the Agent SDK, a framework enabling teams to build custom autonomous agents for development workflows. Instead of adopting pre-built solutions, developers code agents using Markdown prompts and TypeScript tools, then deploy to Cursor infrastructure or self-hosted containers. Agents connect to GitHub, GitLab, and Bitbucket to respond to pull requests and other events, handling code review, compliance, and incident investigation with team-defined policies.

The framework treats agents as code projects. Prompts, tools, service integrations, and test evals all live in version control alongside the same review and CI processes used for production software. Agents can delegate tasks to specialized sub-agents or parallelize work. Built-in support for evals and event replay lets teams validate behavior before deployment.

PGA Tour’s software development factory runs entirely on the SDK. Cursor highlights kb-reviewer—built in one day to flag pull requests contradicting a team’s knowledge base of decisions—as evidence of the platform’s flexibility. The SDK is now generally available.
