Strands Agents (AWS Agent Core)

Integrate AgentSuite with Strands Agents, the open-source framework that powers AWS Agent Core, via the Virtue Gateway for AgentGuard runtime enforcement, access control, MCP server scanning (where enabled), and session observability in the dashboard.

Installation

pip install agentsuite-sdk[strands]

The [strands] extra installs the core strands-agents package needed for the adapter. It does not include an LLM provider — install the one you need separately:

pip install strands-agents[anthropic]   # Anthropic Claude (used in the demo)
pip install strands-agents[openai]     # OpenAI

How It Works

• adapter.mcp_client() — returns a Strands MCPClient to pass into Agent(tools=[...]).
• adapter.hook_provider() — returns a hook provider to pass into Agent(hooks=[...]) for automatic session tracking.

Quickstart

from strands import Agent
from strands.models.anthropic import AnthropicModel
from agentsuite import GatewayClient

client = GatewayClient(url="...", api_key="sk-vai-...")
adapter = client.strands()

model = AnthropicModel(
    client_args={"api_key": "sk-ant-..."},
    model_id="claude-sonnet-4-20250514",
    max_tokens=4096,
)
agent = Agent(
    model=model,
    system_prompt="You are a helpful assistant.",
    tools=[adapter.mcp_client()],
    hooks=[adapter.hook_provider()],
)

agent("What are my open tickets?")

Example Output

The agent responds to the query and prints the session ID:
