(an example is provided in the Appendix below).
39+
40+
"Derivative Works" shall mean any work, whether in Source or Object
41+
form, that is based on (or derived from) the Work and for which the
42+
editorial revisions, annotations, elaborations, or other modifications
43+
represent, as a whole, an original work of authorship. For the purposes
44+
of this License, Derivative Works shall not include works that remain
45+
separable from, or merely link (or bind by name) to the interfaces of,
46+
the Work and Derivative Works thereof.
47+
48+
"Contribution" shall mean any work of authorship, including

67+
this License, each Contributor hereby grants to You a perpetual,
68+
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
69+
copyright license to reproduce, prepare Derivative Works of,

79+
by such Contributor that are necessarily infringed by their
80+
Contribution(s) alone or by combination of their Contribution(s)
81+
with the Work to which such Contribution(s) was submitted. If You

institute patent litigation against any entity (including a
83+
cross-claim or counterclaim in a lawsuit) alleging that the Work
84+
or a Contribution incorporated within the Work constitutes direct
85+
or contributory patent infringement, then any patent licenses
86+
granted to You under this License for that Work shall terminate
87+
as of the date such litigation is filed.
88+
89+
4. Redistribution. You may reproduce and distribute copies of the
90+
Work or Derivative Works thereof in any medium, with or without
91+
modifications, and in Source or Object form, provided that You
92+
meet the following conditions:
93+
94+
(a) You must give any other recipients of the Work or
95+
Derivative Works a copy of this License; and
96+
97+
(b) You must cause any modified files to carry prominent notices
98+
stating that You changed the files; and
99+
100+
(c) You must retain, in the Source form of any Derivative Works
101+
that You distribute, all copyright, patent, trademark, and
102+
attribution notices from the Source form of the Work,
103+
excluding those notices that do not pertain to any part of
104+
the Derivative Works; and
105+
106+
(d) If the Work includes a "NOTICE" text file as part of its
107+
distribution, then any Derivative Works that You distribute must
108+
include a readable copy of the attribution notices contained
109+
within such NOTICE file, excluding those notices that do not
110+
pertain to any part of the Derivative Works, in at least one
111+
of the following places: within a NOTICE text file distributed
112+
as part of the Derivative Works; within the Source form or
113+
documentation, if provided along with the Derivative Works; or,
114+
within a display generated by the Derivative Works, if and
115+
wherever such third-party notices normally appear. The contents
116+
of the NOTICE file are for informational purposes only and
117+
do not modify the License. You may add Your own attribution
118+
notices within Derivative Works that You distribute, alongside
119+
or as an addendum to the NOTICE text from the Work, provided
120+
that such additional attribution notices cannot be construed
121+
as modifying the License.
122+
123+
You may add Your own copyright statement to Your modifications and
124+
may provide additional or different license terms and conditions
125+
for use, reproduction, or distribution of Your modifications, or
126+
for any such Derivative Works as a whole, provided Your use,
127+
reproduction, and distribution of the Work otherwise complies with
128+
the conditions stated in this License.
129+
130+
5. Submission of Contributions. Unless You explicitly state otherwise,
131+
any Contribution intentionally submitted for inclusion in the Work
132+
by You to the Licensor shall be under the terms and conditions of
133+
this License, without any additional terms or conditions.
134+
Notwithstanding the above, nothing herein shall supersede or modify
135+
the terms of any separate license agreement you may have executed
136+
with Licensor regarding such Contributions.
137+
138+
6. Trademarks. This License does not grant permission to use the trade
139+
names, trademarks, service marks, or product names of the Licensor,
140+
except as required for reasonable and customary use in describing the
141+
origin of the Work and reproducing the content of the NOTICE file.
142+
143+
7. Disclaimer of Warranty. Unless required by applicable law or
144+
agreed to in writing, Licensor provides the Work (and each
145+
Contributor provides its Contributions) on an "AS IS" BASIS,
146+
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
147+
implied, including, without limitation, any warranties or conditions
148+
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
149+
PARTICULAR PURPOSE. You are solely responsible for determining the
150+
appropriateness of using or redistributing the Work and assume any
151+
risks associated with Your exercise of permissions under this License.
152+
153+
8. Limitation of Liability. In no event and under no legal theory,
154+
whether in tort (including negligence), contract, or otherwise,
155+
unless required by applicable law (such as deliberate and grossly
156+
negligent acts) or agreed to in writing, shall any Contributor be
157+
liable to You for damages, including any direct, indirect, special,
158+
incidental, or consequential damages of any character arising as a
159+
result of this License or out of the use or inability to use the
160+
Work (including but not limited to damages for loss of goodwill,
161+
work stoppage, computer failure or malfunction, or any and all
162+
other commercial damages or losses), even if such Contributor
163+
has been advised of the possibility of such damages.
164+
165+
9. Accepting Warranty or Additional Liability. While redistributing
166+
the Work or Derivative Works thereof, You may choose to offer,
167+
and charge a fee for, acceptance of support, warranty, indemnity,
168+
or other liability obligations and/or rights consistent with this
169+
License. However, in accepting such obligations, You may act only
170+
on Your own behalf and on Your sole responsibility, not on behalf of
171+
any other Contributor, and only if You agree to indemnify,
172+
defend, and hold each Contributor harmless for any liability
173+
incurred by, or claims asserted against, such Contributor by reason
174+
of your accepting any such warranty or additional liability.

## Capabilities
33+
34+
The Agents SDK provides:
35+
36+
- **Persistent state** - SQLite-backed, auto-synced to clients
37+
- **Callable RPC** - `@callable()` methods invoked over WebSocket
38+
- **Scheduling** - One-time, recurring (`scheduleEvery`), and cron tasks
39+
- **Workflows** - Durable multi-step background processing via `AgentWorkflow`
40+
- **MCP integration** - Connect to MCP servers or build your own with `McpAgent`
41+
- **Email handling** - Receive and reply to emails with secure routing
42+
- **Streaming chat** - `AIChatAgent` with resumable streams
43+
- **React hooks** - `useAgent`, `useAgentChat` for client apps
44+
45+
## FIRST: Verify Installation
46+
47+
```bash
48+
npm ls agents # Should show agents package
49+
```
50+
51+
If not installed:
52+
```bash
53+
npm install agents
54+
```
55+
56+
## Wrangler Configuration
57+
58+
```jsonc
59+
{
60+
"durable_objects": {
61+
"bindings": [{ "name": "MyAgent", "class_name": "MyAgent" }]
62+
},
63+
"migrations": [{ "tag": "v1", "new_sqlite_classes": ["MyAgent"] }]
64+
}
65+
```
66+
67+
## Agent Class
68+
69+
```typescript
70+
import { Agent, routeAgentRequest, callable } from "agents";
71+
72+
type State = { count: number };
73+
74+
export class Counter extends Agent<Env, State> {
75+
initialState = { count: 0 };
76+
77+
// Validation hook - runs before state persists (sync, throwing rejects the update)
78+
validateStateChange(nextState: State, source: Connection | "server") {
79+
if (nextState.count < 0) throw new Error("Count cannot be negative");
80+
}
81+
82+
// Notification hook - runs after state persists (async, non-blocking)
83+
onStateUpdate(state: State, source: Connection | "server") {
84+
console.log("State updated:", state);
85+
}
86+
87+
@callable()
88+
increment() {
89+
this.setState({ count: this.state.count + 1 });
90+
return this.state.count;
91+
}
92+
}
93+
94+
export default {
95+
fetch: (req, env) => routeAgentRequest(req, env) ?? new Response("Not found", { status: 404 })
96+
};
97+
```
98+
99+
## Routing
100+
101+
Requests route to `/agents/{agent-name}/{instance-name}`:
102+
103+
| Class | URL |
104+
|-------|-----|
105+
| `Counter` | `/agents/counter/user-123` |
106+
| `ChatRoom` | `/agents/chat-room/lobby` |
107+
108+
Client: `useAgent({ agent: "Counter", name: "user-123" })`
109+
110+
## Core APIs
111+
112+
| Task | API |
113+
|------|-----|
114+
| Read state | `this.state.count` |
115+
| Write state | `this.setState({ count: 1 })` |
116+
| SQL query | `` this.sql`SELECT * FROM users WHERE id = ${id}` `` |
117+
| Schedule (delay) | `await this.schedule(60, "task", payload)` |
118+
| Schedule (cron) | `await this.schedule("0 * * * *", "task", payload)` |
119+
| Schedule (interval) | `await this.scheduleEvery(30, "poll")` |
120+
| RPC method | `@callable() myMethod() { ... }` |
121+
| Streaming RPC | `@callable({ streaming: true }) stream(res) { ... }` |
122+
| Start workflow | `await this.runWorkflow("ProcessingWorkflow", params)` |
123+
124+
## React Client
125+
126+
```tsx
127+
import { useAgent } from "agents/react";
128+
129+
function App() {
130+
const [state, setLocalState] = useState({ count: 0 });
131+
132+
const agent = useAgent({
133+
agent: "Counter",
134+
name: "my-instance",
135+
onStateUpdate: (newState) => setLocalState(newState),
136+
onIdentity: (name, agentType) => console.log(`Connected to ${name}`)
137+
});
138+
139+
return (
140+
<button onClick={() => agent.setState({ count: state.count + 1 })}>
141+
Count: {state.count}
142+
</button>
143+
);
144+
}
145+
```
