## Introducing the Agents SDK

Feb 25, 2025 

[ Agents ](https://edgetunnel-b2h.pages.dev/agents/)[ Workers ](https://edgetunnel-b2h.pages.dev/workers/) 

We've released the [Agents SDK ↗](http://blog.cloudflare.com/build-ai-agents-on-cloudflare/), a package and set of tools that help you build and ship AI Agents.

You can get up and running with a [chat-based AI Agent ↗](https://github.com/cloudflare/agents-starter) (and deploy it to Workers) that uses the Agents SDK, tool calling, and state syncing with a React-based front-end by running the following command:

```sh
npm create cloudflare@latest agents-starter -- --template="cloudflare/agents-starter"
# open up README.md and follow the instructions
```

You can also add an Agent to any existing Workers application by installing the `agents` package directly

```sh
npm i agents
```

... and then define your first Agent:

**TypeScript**

```ts
import { Agent } from "agents";


export class YourAgent extends Agent<Env> {
  // Build it out
  // Access state on this.state or query the Agent's database via this.sql
  // Handle WebSocket events with onConnect and onMessage
  // Run tasks on a schedule with this.schedule
  // Call AI models
  // ... and/or call other Agents.
}
```

Head over to the [Agents documentation](https://edgetunnel-b2h.pages.dev/agents/) to learn more about the Agents SDK, the SDK APIs, as well as how to test and deploying agents to production.
