Release Notes
Agent SDK
The Agent SDK is available today. It allows you to define an agent as a folder of code, test it with evals, and deploy it to Cursor or your own infrastructure.
Run npx @cursor/agent-sdk init ./my-bot, then agent-sdk dev to start the bot locally with a playground. Pass --template to start from a security reviewer, an owners-policy approver, a PR autofixer, or a Linear or Jira triager.
Deploy agents wherever you need them
When you're ready to put an agent into use, you can deploy it to Cursor by running agent-sdk deploy from the project directory. The command builds the agent, gives it a URL, and starts it on our infrastructure. You can manage secrets and integrations from the dashboard, while continuing to use the same logs, evals, and playground available locally.
Agents as code
An agent is a project. instructions.md is the prompt. Each file in tools/ is one typed action the model can call. skills/ holds procedures the model loads on demand, mcp-connections/ adds tools from MCP servers, and channels/ defines where the bot receives and answers messages. agent-sdk validate checks the project and agent-sdk info prints what was discovered.
Channels
Agents wake on pull request, comment, and CI events from GitHub, GitLab, and Bitbucket; on mentions and DMs in Slack; on webhooks from any provider; and on a cron schedule. GitHub events pull through your Cursor account, so no public webhook URL is required. Slack is well-supported out of the box.
Each conversation keeps its own session and a complete record of every message and tool call. Follow-ups on a pull request or Slack thread resume the same session.
Evals
An eval sends a fixed message to the bot and asserts on what it did: which tools ran, with what input, and the shape of the reply. Run agent-sdk eval locally or in CI.
agent-sdk github replay <pr-url> turns a real pull request into signed webhook payloads and sends them to the bot, so GitHub-driven bots can be tested without waiting for a push. Add --dry-run --fixtures-dir fixtures/ to save the payloads as eval fixtures.
Get started
The Agent SDK is generally available today. Read the docs and get started.
