Strands Agents Examples

Strands Agents is AWS's open-source Python agent SDK. AgentVisor integrates natively with Strands — your agents run inside a hardened sandbox with policy enforcement, credential brokering, and durable snapshot-based checkpointing via Temporal.

Prerequisites

• Anthropic API key (or another LiteLLM-supported model endpoint) — the examples use Claude via LiteLLM and the AgentVisor proxy
• Temporal — required for durable execution
• AgentVisor CLI — agentvisor serve . starts the runtime
• uvx on your PATH — used by the research agent's MCP fetch tool (pip install uv)

Examples

Example	Difficulty	Key Feature
Research Agent	Intermediate	Web research with MCP tools, LiteLLM model, snapshot checkpointing
Graph Approval Agent	Advanced	Two-node Graph, MultiAgent checkpointing, interrupt/resume approval

How It Works

Strands agents in AgentVisor work through the Strands framework provider:

1. Selection: Strands has no discovery file, so mav-agent-config.yaml must explicitly set framework.provider: "strands"
2. Schema extraction: register_agent() registers the root agent for schema extraction and runner resolution
3. Execution: python3 -m agentvisor.strands.runner resolves the root agent, silences Strands' default stdout-printing callback handler, loads any prior snapshot for the thread, invokes the agent, and saves the resulting snapshot
4. Checkpointing: agent.take_snapshot(preset="session")/agent.load_snapshot() are wired automatically through AgentVisor's simple checkpoint API, keyed by thread

Key Concepts

Concept	What It Is	Where You'll See It
mav-agent-config.yaml	Required explicit provider selection (framework.provider: "strands")	All examples
register_agent()	Registers root agent for schema extraction and runner resolution	All examples
agentvisor.strands.mcp.get_mcp_tools()	Native MCP tool adapter (no LangChain dependency)	Research Agent
Snapshot checkpointing	take_snapshot()/load_snapshot() wired through checkpoint.save()/load()	Research Agent
MultiAgent checkpointing	serialize_state()/deserialize_state() (Graph/Swarm) wired through the same checkpoint.save()/load() API	Graph Approval Agent
Interrupt/resume	event.interrupt() from a BeforeToolCallEvent hook pauses a run for human approval	Graph Approval Agent
LiteLLM model	Proven production route to Bedrock; used directly against Anthropic here	Research Agent, Graph Approval Agent
