💻 Usage Examples
File Operations
from strands import Agent
from strands_tools import file_read, file_write, editor
agent = Agent(tools=[file_read, file_write, editor])
agent.tool.file_read(path="config.json")
agent.tool.file_write(path="output.txt", content="Hello, world!")
agent.tool.editor(command="view", path="script.py")
Dynamic MCP Client Integration
⚠️ SECURITY WARNING: The Dynamic MCP Client allows agents to autonomously connect to external MCP servers and load remote tools at runtime. This poses significant security risks as agents can potentially connect to malicious servers and execute untrusted code. Use with extreme caution in production environments.
This tool is different from the static MCP server implementation in the Strands SDK (see MCP Tools Documentation) which uses pre-configured, trusted MCP servers.
from strands import Agent
from strands_tools import mcp_client
agent = Agent(tools=[mcp_client])
# Connect to a custom MCP server via stdio
agent.tool.mcp_client(
action="connect",
connection_id="my_tools",
transport="stdio",
command="python",
args=["my_mcp_server.py"]
)
# List available tools on the server
tools = agent.tool.mcp_client(
action="list_tools",
connection_id="my_tools"
)
# Call a tool from the MCP server
result = agent.tool.mcp_client(
action="call_tool",
connection_id="my_tools",
tool_name="calculate",
tool_args={"x": 10, "y": 20}
)
# Connect to a SSE-based server
agent.tool.mcp_client(
action="connect",
connection_id="web_server",
transport="sse",
server_url="http://localhost:8080/sse"
)
# Connect to a streamable HTTP server
agent.tool.mcp_client(
action="connect",
connection_id="http_server",
transport="streamable_http",
server_url="https://api.example.com/mcp",
headers={"Authorization": "Bearer token"},
timeout=60
)
# Load MCP tools into agent's registry for direct access
# ⚠️ WARNING: This loads external tools directly into the agent
agent.tool.mcp_client(
action="load_tools",
connection_id="my_tools"
)
# Now you can call MCP tools directly as: agent.tool.calculate(x=10, y=20)

Graph (Multi-Agent DAG)
Create deterministic DAG-based multi-agent pipelines where agents are nodes with dependency relationships. Unlike agent_graph (which uses persistent message-passing), graph uses task-based execution with output propagation.

agent = Agent(tools=[graph])

result = agent.tool.graph(
action="create",

🌍 Environment Variables Configuration
Agents Tools provides extensive customization through environment variables. This allows you to configure tool behavior without modifying code, making it ideal for different environments (development, testing, production).
Global Environment Variables
These variables affect multiple tools:
| Environment Variable | Description | Default | Affected Tools |
|---|---|---|---|
| BYPASS_TOOL_CONSENT | Bypass consent for tool invocation, set to "true" to enable | false | All tools that require consent (e.g. shell, file_write, python_repl) |
| STRANDS_NON_INTERACTIVE | Run tools without interactive prompts, set to "true" to suppress confirmation dialogs | false | Tools with a confirmation prompt (e.g. shell, python_repl) |
| STRANDS_TOOL_CONSOLE_MODE | Enable rich UI for tools, set to "enabled" to enable | disabled | All tools that have optional rich UI |
| AWS_REGION | Defau |
