🆕 NEWS

• [2026-02] A major architectural refactor of AgentApp in v1.1.0. By adopting direct inheritance from FastAPI and deprecating the previous factory pattern, AgentApp now offers seamless integration with the full FastAPI ecosystem, significantly boosting extensibility. Furthermore, we’ve introduced a Distributed Interrupt Service, enabling manual task preemption during agent execution and allowing developers to customize state persistence and recovery logic flexibly. Please refer to the CHANGELOG for full update details and migration guide.
• [2026-01] Added asynchronous sandbox implementations (BaseSandboxAsync, GuiSandboxAsync, BrowserSandboxAsync, FilesystemSandboxAsync, MobileSandboxAsync) enabling non-blocking, concurrent tool execution in async program. Improved run_ipython_cell and run_shell_command methods with enhanced concurrency and parallel execution capabilities for more efficient sandbox operations.
• [2025-12] We have released AgentScope Runtime v1.0, introducing a unified “Agent as API” white-box development experience, with enhanced multi-agent collaboration, state persistence, and cross-framework integration. This release also streamlines abstractions and modules to ensure consistency between development and production environments. Please refer to the CHANGELOG for full update details and migration guide.

Agent App Example

This example demonstrates how to create an agent API server using agentscope ReActAgent and AgentApp. To run a minimal AgentScope Agent with AgentScope Runtime, you generally need to implement:

1. Define lifespan – Use contextlib.asynccontextmanager to manage resource initialization (e.g., state services) at startup and cleanup on exit.
2. @agent_app.query(framework="agentscope") – Core logic for handling requests, must use stream_printing_messages to yield msg, last for streaming output

import os
from contextlib import asynccontextmanager

from fastapi import FastAPI
from agentscope.agent import ReActAgent
from agentscope.model import DashScopeChatModel
from agentscope.formatter import DashScopeChatFormatter
from agentscope.tool import Toolkit, execute_python_code
from agentscope.pipeline import stream_printing_messages
from agentscope.memory import InMemoryMemory
from agentscope.session import RedisSession

from agentscope_runtime.engine import AgentApp
from agentscope_runtime.engine.schemas.agent_schemas import AgentRequest

# 1. Define lifespan manager
@asynccontextmanager
async def lifespan(app: FastAPI):
    """Manage resources during service startup and shutdown"""
    # Startup: Initialize Session manager
    import fakeredis

    fake_redis = fakeredis.aioredis.FakeRedis(decode_responses=True)
    # NOTE: This FakeRedis instance is for development/testing only.
    # In production, replace it with your own Redis client/connection
    # (e.g., aioredis.Redis)
    app.state.session = RedisSession(connection_pool=fake_redis.connection_pool)

    yield  # Service is running

    # Shutdown: Add cleanup logic here (e.g., closing database connections)
    print("AgentApp is shutting down...")

# 2. Create AgentApp instance
agent_app = AgentApp(
    app_name="Friday",
    app_description="A helpful assistant",
    lifespan=lifespan,
)

# 3. Define request handling logic
@agent_app.query(framework="agentscope")
async def query_func(
    self,
    msgs,
    request: AgentRequest = None,
    **kwargs,
):
    session_id = request.session_id
    user_id = request.user_id

    toolkit = Toolkit()
    toolkit.register_tool_function(execute_python_code)

    agent = ReActAgent(
        name="Friday",
        model=DashScopeChatModel(
            "qwen-turbo",
            api_key=os.getenv("DASHSCOPE_API_KEY"),
            stream=True,
        ),
        sys_prompt="You're a helpful assistant named Friday.",
        toolkit=toolkit,
        memory=InMemoryMemory(),
        formatter=DashScopeChatFormatter(),
    )
    agent.set_console_output_enabled(enabled=False)

    # Load state
    await agent_app.state.session.load_session_state(
        session_id=session_id,
        user_id=user_id,
        agent=agent,
    )

    async for msg, last in stream_printing_messages(
        agents=[agent],
        coroutine_task=agent(msgs),
    ):
        yield msg, last

    # Save state
    await agent_app.state.session.save_session_state(
        session_id=session_id,
        user_id=user_id,
        agent=agent,
    )

# 4. Run the application
agent_app.run(host="127.0.0.1", port=8090)

The server will start and listen on: http://localhost:8090/process. You can send JSON input to the API using curl:

curl -N \
  -X POST "http://localhost:8090/process" \
  -H "Content-Type: application/json" \
  -d '{
    "input": [
      {
        "role": "user",
        "content": [
          { "type": "text", "text": "What is the capital of France?" }
        ]
      }
    ]
  }'

You’ll see output streamed in Server-Sent Events (SSE) format:

data: {"sequence_number":0,"object":"response","status":"created", ... }
data: {"sequence_number":1,"object":"response","status":"in_progress", ... }
data: {"sequence_number":2,"object":"message","status":"in_progress", ... }
data: {"sequence_number":3,"object":"content","status":"in_progress","text":"The" }
data: {"sequence_number":4,"object":"content","status":"in_progress","text":" capital of France is Paris." }
data: {"sequence_number":5,"object":"message","status":"completed","text":"The capital of France is Paris." }
data: {"sequence_number":6,"object":"response","status":"completed", ... }

Mobile Sandbox

Provides a sandboxed Android emulator environment that allows executing various mobile operations, such as tapping, swiping, inputting text, and taking screenshots.

Prerequisites

• Linux Host: When running on a Linux host, this sandbox requires the binder and ashmem kernel modules to be loaded. If they are missing, execute the following commands on your host to install and load the required modules:

  # 1. Install extra kernel modules
  sudo apt update && sudo apt install -y linux-modules-extra-`uname -r`
  
  # 2. Load modules and create device nodes
  sudo modprobe binder_linux devices="binder,hwbinder,vndbinder"
  sudo modprobe ashmem_linux
  

• Architecture Compatibility: When running on an ARM64/aarch64 architecture (e.g., Apple M-series chips), you may encounter compatibility or performance issues. It is recommended to run on an x86_64 host.

# --- Synchronous version ---
from agentscope_runtime.sandbox import MobileSandbox

with MobileSandbox() as box:
    # By default, pulls 'agentscope/runtime-sandbox-mobile:latest' from DockerHub
    print(box.list_tools())  # List all available tools
    print(box.mobile_get_screen_resolution())  # Get the screen resolution
    print(box.mobile_tap([500, 1000]))  # Tap at coordinate (500, 1000)
    print(box.mobile_input_text("Hello from AgentScope!"))  # Input text
    print(box.mobile_key_event(3))  # HOME key event
    screenshot_result = box.mobile_get_screenshot()  # Get screenshot
    print(screenshot_result)
    input("Press Enter to continue...")

# --- Asynchronous version ---
from agentscope_runtime.sandbox import MobileSandboxAsync

async with MobileSandboxAsync() as box:
    # Default image is 'agentscope/runtime-sandbox-mobile:latest'
    print(await box.list_tools_async())  # List all available tools
    print(await box.mobile_get_screen_resolution())  # Get the screen resolution
    print(await box.mobile_tap([500, 1000]))  # Tap at coordinate (500, 1000)
    print(await box.mobile_input_text("Hello from AgentScope!"))  # Input text
    print(await box.mobile_key_event(3))  # HOME key event
    screenshot_result = await box.mobile_get_screenshot()  # Get screenshot
    print(screenshot_result)
    input("Press Enter to continue...")

Configuring Sandbox Image Registry, Namespace, and Tag

1. Registry

If pulling images from DockerHub fails (for example, due to network restrictions), you can switch the image source to Alibaba Cloud Container Registry for faster access:

export RUNTIME_SANDBOX_REGISTRY="agentscope-registry.ap-southeast-1.cr.aliyuncs.com"

2. Namespace

A namespace is used to distinguish images of different teams or projects. You can customize the namespace via an environment variable:

export RUNTIME_SANDBOX_IMAGE_NAMESPACE="agentscope"

For example, here agentscope will be used as part of the image path.

3. Tag

An image tag specifies the version of the image, for example:

export RUNTIME_SANDBOX_IMAGE_TAG="preview"

Details:

• Default is latest, which means the image version matches the PyPI latest release.
• preview means the latest preview version built in sync with the GitHub main branch.
• You can also use a specified version number such as 20250909. You can check all available image versions at DockerHub.

4. Complete Image Path

The sandbox SDK will build the full image path based on the above environment variables:

<RUNTIME_SANDBOX_REGISTRY>/<RUNTIME_SANDBOX_IMAGE_NAMESPACE>/runtime-sandbox-base:<RUNTIME_SANDBOX_IMAGE_TAG>

Example:

agentscope-registry.ap-southeast-1.cr.aliyuncs.com/agentscope/runtime-sandbox-base:preview

Serverless Sandbox Deployment

AgentScope Runtime also supports serverless deployment, which is suitable for running sandboxes in a serverless environment, e.g. Alibaba Cloud Function Compute (FC).

First, please refer to the documentation to configure the serverless environment variables. Make CONTAINER_DEPLOYMENT to fc to enable serverless deployment.

Then, start a sandbox server, use the --config option to specify a serverless environment setup:

# This command will load the settings defined in the `custom.env` file
runtime-sandbox-server --config fc.env

After the server starts, you can access the sandbox server at baseurl http://localhost:8000 and invoke sandbox tools described above.

Deployment Example

The AgentApp exposes a deploy method that takes a DeployManager instance and deploys the agent.

• The service port is set as the parameter port when creating the LocalDeployManager.

• The service endpoint path is set as the parameter endpoint_path to /process when deploying the agent.

• The deployer will automatically add common agent protocols, such as A2A, Response API.

After deployment, users can access the service at http://localhost:8090/process:

from agentscope_runtime.engine.deployers import LocalDeployManager

# Create deployment manager
deployer = LocalDeployManager(
    host="0.0.0.0",
    port=8090,
)

# Deploy the app as a streaming service
deploy_result = await app.deploy(
    deployer=deployer,
    endpoint_path="/process"
)

After deployment, users can also access this service using the Response API of the OpenAI SDK:

from openai import OpenAI

client = OpenAI(base_url="http://localhost:8090/compatible-mode/v1")

response = client.responses.create(
  model="any_name",
  input="What is the weather in Beijing?"
)

print(response)

Besides, DeployManager also supports serverless deployments, such as deploying your agent app to ModelStudio.

import os
from agentscope_runtime.engine.deployers.modelstudio_deployer import (
    ModelstudioDeployManager,
    OSSConfig,
    ModelstudioConfig,
)

# Create deployment manager
deployer = ModelstudioDeployManager(
    oss_config=OSSConfig(
        access_key_id=os.environ.get("ALIBABA_CLOUD_ACCESS_KEY_ID"),
        access_key_secret=os.environ.get("ALIBABA_CLOUD_ACCESS_KEY_SECRET"),
    ),
    modelstudio_config=ModelstudioConfig(
        workspace_id=os.environ.get("MODELSTUDIO_WORKSPACE_ID"),
        access_key_id=os.environ.get("ALIBABA_CLOUD_ACCESS_KEY_ID"),
        access_key_secret=os.environ.get("ALIBABA_CLOUD_ACCESS_KEY_SECRET"),
        dashscope_api_key=os.environ.get("DASHSCOPE_API_KEY"),
    ),
)

# Deploy to ModelStudio
result = await app.deploy(
    deployer,
    deploy_name="agent-app-example",
    telemetry_enabled=True,
    requirements=["agentscope", "fastapi", "uvicorn"],
    environment={
        "PYTHONPATH": "/app",
        "DASHSCOPE_API_KEY": os.environ.get("DASHSCOPE_API_KEY"),
    },
)
