## What is AgentScope 2.0?

AgentScope 2.0 is a production-ready, easy-to-use agent framework with essential abstractions that work with rising model capability and built-in support for .

- [**Event System** →](https://docs.agentscope.io/v2/building-blocks/message-and-event) A unified event bus to the frontend and human-in-the-loop support.
- [**Permission System** →](https://docs.agentscope.io/v2/building-blocks/permission-system) Fine-grained, configurable control over tools and resources.
- [**Multi-tenancy & Multi-session Service** →](https://docs.agentscope.io/v2/deploy/agent-service) Production-grade serving with isolation across tenants and sessions.
- [**Workspace / Sandbox Support** →](https://docs.agentscope.io/v2/building-blocks/workspace) Run tools and code in isolated environments, with built-in backends for local, Docker, and E2B.
- [**Extensible Middleware System** →](https://docs.agentscope.io/v2/building-blocks/middleware) Composable hooks to customize and extend the agent's reasoning-acting loop.

We design for increasingly agentic LLMs.
Our approach leverages the models' reasoning and tool use abilities
rather than constraining them with strict prompts and opinionated orchestrations.

## Quickstart

### Installation

> AgentScope requires **Python 3.11** or higher.

#### From PyPI

```bash
uv pip install agentscope
# or
# pip install agentscope
```

#### From source

```bash
# Pull the source code from GitHub
git clone -b main https://github.com/agentscope-ai/agentscope.git

# Install the package in editable mode
cd agentscope

uv pip install -e .
# or
# pip install -e .
```

## Hello AgentScope!

Start your first agent with AgentScope 2.0:

```python
from agentscope.agent import Agent
from agentscope.tool import Toolkit, Bash, Grep, Glob, Read, Write, Edit
from agentscope.credential import DashScopeCredential
from agentscope.model import DashScopeChatModel
from agentscope.message import UserMsg
from agentscope.event import EventType

import os, asyncio


async def main() -> None:
    agent = Agent(
        name="Friday",
        system_prompt="You're a helpful assistant named Friday.",
        model=DashScopeChatModel(
            credential=DashScopeCredential(
              api_key=os.environ["DASHSCOPE_API_KEY"]
            ),
            model="qwen3.6-plus",
        ),
        toolkit=Toolkit(
            tools=[
                Bash(),
                Grep(),
                Glob(),
                Read(),
                Write(),
                Edit(),
            ]
        ),
    )

    async for evt in agent.reply_stream(UserMsg("Tony", "Hi, Friday!")):
        # Handle the event stream, e.g., print the message, update UI, etc.
        match evt.type:
            case EventType.REPLY_START:
                ...
            case EventType.MODEL_CALL_START:
                ...
            case EventType.TEXT_BLOCK_START:
                ...
            case EventType.TEXT_BLOCK_DELTA:
                ...
            case EventType.TEXT_BLOCK_END:
                ...

            # Handle other event types

asyncio.run(main())
```

## Hello Agent Service!

An extensible FastAPI based **multi-tenancy**, **multi-session** agent service with pre-built Web UI in `examples/web_ui`

Run the following commands to start the agent service backend and the web UI:

```bash
git clone -b main https://github.com/agentscope-ai/agentscope.git
cd agentscope/examples/agent_service

# start the agent service backend
python main.py
```

Then open another terminal to start the web UI:

```bash
cd agentscope/examples/web_ui

# start the webui
pnpm install
pnpm dev
```
