Strands Agents is a simple yet powerful SDK that takes a model-driven approach to building and running AI agents. From simple conversational assistants to complex autonomous workflows, from local development to production deployment, Strands Agents scales with your needs.
## Feature Overview
- **Lightweight & Flexible**: Simple agent loop that just works and is fully customizable
- **Model Agnostic**: Support for Amazon Bedrock, Anthropic, Gemini, LiteLLM, Llama, Ollama, OpenAI, Writer, and custom providers
- **Advanced Capabilities**: Multi-agent systems, autonomous agents, and streaming support
- **Built-in MCP**: Native support for Model Context Protocol (MCP) servers, enabling access to thousands of pre-built tools
## Quick Start
```bash
# Install Strands Agents
pip install strands-agents strands-agents-tools
```
```python
from strands import Agent
from strands_tools import calculator
agent = Agent(tools=[calculator])
agent("What is the square root of 1764")
```
> **Note**: For the default Amazon Bedrock model provider, you'll need AWS credentials configured and model access enabled for Claude 4 Sonnet in the us-west-2 region. See the [Quickstart Guide](https://strandsagents.com/) for details on configuring other model providers.
## Installation
Ensure you have Python 3.10+ installed, then:
```bash
# Create and activate virtual environment
python -m venv .venv
source .venv/bin/activate # On Windows use: .venv\Scripts\activate
# Install Strands and tools
pip install strands-agents strands-agents-tools
```
## Features at a Glance
### Python-Based Tools
Easily build tools using Python decorators:
```python
from strands import Agent, tool
@tool
def word_count(text: str) -> int:
"""Count words in text.
This docstring is used by the LLM to understand the tool's purpose.
"""
return len(text.split())
agent = Agent(tools=[word_count])
response = agent("How many words are in this sentence?")
```
**Hot Reloading from Directory:**
Enable automatic tool loading and reloading from the `./tools/` directory:
```python
from strands import Agent
# Agent will watch ./tools/ directory for changes
agent = Agent(load_tools_from_directory=True)
response = agent("Use any tools you find in the tools directory")
```
### MCP Support
Connect to Model Context Protocol (MCP) servers:
```python
from strands import Agent
from strands.tools.mcp import MCPClient
from mcp import stdio_client, StdioServerParameters
aws_docs_client = MCPClient(
lambda: stdio_client(StdioServerParameters(command="uvx", args=["awslabs.aws-documentation-mcp-server@latest"]))
)
with aws_docs_client:
agent = Agent(tools=aws_docs_client.list_tools_sync())
response = agent("Tell me about Amazon Bedrock and how to use it with Python")
```
The SDK works with both major versions of the `mcp` package through a built-in compatibility layer, so most code that uses `MCPClient` runs unchanged on either version. A fresh install resolves to mcp 2.x, and pinning `mcp<2` keeps you on 1.x. See [docs/MCP_VERSIONS.md](./docs/MCP_VERSIONS.md) for support status, the behavior differences on 2.x, and migration notes.
### Multiple Model Providers
Support for various model providers:
```python
from strands import Agent
from strands.models import BedrockModel
from strands.models.ollama import OllamaModel
from strands.models.llamaapi import LlamaAPIModel
from strands.models.gemini import GeminiModel
from strands.models.llamacpp import LlamaCppModel
# Bedrock
bedrock_model = BedrockModel(
model_id="us.amazon.nova-pro-v1:0",
temperature=0.3,
streaming=True, # Enable/disable streaming
)
agent = Agent(model=bedrock_model)
agent("Tell me about Agentic AI")
# Google Gemini
gemini_model = GeminiModel(
client_args={
"api_key": "your_gemini_api_key",
},
model_id="gemini-2.5-flash",
params={"temperature": 0.7}
)
agent = Agent(model=gemini_model)
agent("Tell me about Agentic AI")
# Ollama
ollama_model = OllamaModel(
host="http://localhost:11434",
model_id="llama3"
)
agent = Agent(model=ollama_model)
agent("Tell me about Agentic AI")
# Llama API
llama_model = LlamaAPIModel(
model_id="Llama-4-Maverick-17B-128E-Instruct-FP8",
)
agent = Agent(model=llama_model)
response = agent("Tell me about Agentic AI")
```
Built-in providers:

### Example tools
Strands offers an optional strands-agents-tools package with pre-built tools for quick experimentation:
```python
from strands import Agent
from strands_tools import calculator
agent = Agent(tools=[calculator])
agent("What is the square root of 1764")
```
It's also available on GitHub via [strands-agents/tools](https://github.com/strands-agents/tools).
### Bidirectional Streaming
> **⚠️ Experimental Feature**: Bidirectional streaming is currently in experimental status. APIs may change in future releases as we refine the feature based on user feedback and evolving model capabilities.
Build real-time voice and audio conversations with persistent streaming connections. Unlike traditional request-response patterns, bidirectional streaming maintains long-running conversations where users can interrupt, provide continuous input, and receive real-time audio responses. Get started with your first BidiAgent by following the [Quickstart](https://strandsagents.com/docs/user-guide/concepts/bidirectional-streaming/quickstart/) guide.
**Supported Model Providers:**
- Amazon Bedrock Nova Sonic
- Google Gemini Live
- OpenAI Realtime API
**Installation:**
```bash
# Server-side only (no audio I/O dependencies)
pip install strands-agents[bidi]
# With all portable Bidi providers, terminal I/O, and audio processing (no local audio devices)
pip install strands-agents[bidi-all]
# For local microphone/speaker access, install PortAudio for your OS first, then:
pip install strands-agents[bidi,bidi-io,bidi-pyaudio]
```
> **Note**: Bedrock Nova Sonic requires Python 3.12+ due to its experimental AWS SDK dependency.
**Quick Example:**
```python
import asyncio
from strands.experimental.bidi.agent import BidiAgent
from strands.experimental.bidi.models import BedrockNovaSonicModel
from strands.experimental.bidi.io import AudioIO
from strands_tools import calculator, stop
async def main():
# Create bidirectional agent with Nova Sonic v2
model = BedrockNovaSonicModel(model_id="amazon.nova-2-sonic-v1:0")
agent = BidiAgent(model=model, tools=[calculator, stop])
# Setup audio I/O (local audio requires the bidi-pyaudio extra)
audio_io = AudioIO()
# Run with real-time audio streaming and terminal transcripts
# stop tool allows user to verbally stop agent execution
await agent.run(
inputs=[audio_io.input()],
outputs=[audio_io.output()]
)
if __name__ == "__main__":
asyncio.run(main())
```
> **Note**: `ConsoleIO` is included with the `bidi-io` extra. `AudioIO` requires
> the `bidi-io` and `bidi-pyaudio` extras plus the PortAudio system library. For
> server-side deployments where audio I/O is handled by clients (browsers,
> mobile apps), install only `strands-agents[bidi]` and implement custom
> input/output streams using the `InputStream` and `OutputStream` protocols.
**Configuration Options:**
```python
from strands.experimental.bidi.models import BedrockNovaSonicModel
# Configure audio streams and Nova Sonic session parameters.
model = BedrockNovaSonicModel(
model_id="amazon.nova-2-sonic-v1:0",
audio={
"input": {"sample_rate": 16000},
"output": {"sample_rate": 16000},
},
voice="matthew",
params={
"turnDetectionConfiguration": {
"endpointingSensitivity": "MEDIUM"
},
"inferenceConfiguration": {
"maxTokens": 2048,
"temperature": 0.7
},
},
)
# Configure I/O devices
audio_io = AudioIO(
input_device_index=0, # Specific microphone
output_device_index=1, # Specific speaker
input_buffer_size=10,
output_buffer_size=10
)
```
