Universal Tool Calling Protocol (UTCP) community plugin for [Strands Agents SDK](https://github.com/strands-agents/sdk-python)

## Features

- **Universal Tool Access** - Connect to any UTCP-compatible tool source
- **OpenAPI/Swagger Support** - Automatic tool discovery from API specifications  
- **Multiple Sources** - Connect to multiple tool sources simultaneously
- **Async/Await Support** - Full async support with context managers
- **Type Safe** - Full type hints and validation
- **Easy Integration** - Drop-in tool adapter for Strands agents

**Key Technical Features:**
- **AgentTool Inheritance**: Full inheritance from Strands `AgentTool` base class
- **Tool Name Sanitization**: UUID suffixes for names >64 characters (Bedrock requirement)

## Requirements

- Python 3.10+
- Strands Agents SDK 1.7.0+
- UTCP core libraries 1.0+

## Installation

```bash
pip install strands-agents strands-utcp
```

## Quick Start

### Basic Usage

```python
from strands import Agent
from strands_utcp import UtcpToolAdapter

# Configure UTCP tool adapter
config = {
    "manual_call_templates": [
        {
            "name": "weather_api",
            "call_template_type": "http",
            "url": "https://api.weather.com/utcp",
            "http_method": "GET"
        }
    ]
}

# Use UTCP tools with Strands agent
async def main():
    async with UtcpToolAdapter(config) as adapter:
        # Get available tools
        tools = adapter.list_tools()
        print(f"Found {len(tools)} UTCP tools")
        
        # Create agent with UTCP tools
        agent = Agent(tools=adapter.to_strands_tools())
        
        # Use the agent
        response = await agent.invoke_async("What's the weather like today?")
        print(response.message)

import asyncio
asyncio.run(main())
```

### Tool Discovery

```python
async with UtcpToolAdapter(config) as adapter:
    # List all available tools
    all_tools = adapter.list_tools()
    
    # Search for specific tools
    weather_tools = await adapter.search_tools("weather")
    
    # Get a specific tool
    weather_tool = adapter.get_tool("get_weather")
    
    if weather_tool:
        result = await weather_tool.call(location="New York")
        print(result)
```

### Multiple Sources

```python
config = {
    "manual_call_templates": [
        {
            "name": "petstore",
            "call_template_type": "http", 
            "url": "https://petstore.swagger.io/v2/swagger.json"
        },
        {
            "name": "openlibrary",
            "call_template_type": "http",
            "url": "https://openlibrary.org/static/openapi.json"
        }
    ]
}

async with UtcpToolAdapter(config) as adapter:
    tools = adapter.list_tools()
    print(f"Total tools from all sources: {len(tools)}")
```

## Configuration

### Supported Call Template Types

The plugin supports all UTCP call template types:

#### HTTP Templates
```python
{
    "name": "api_name",
    "call_template_type": "http",
    "url": "https://api.example.com/utcp",
    "http_method": "GET",  # GET, POST, PUT, DELETE
    "content_type": "application/json"
}
```

#### Server-Sent Events (SSE)
```python
{
    "name": "sse_stream",
    "call_template_type": "sse", 
    "url": "https://api.example.com/stream",
    "http_method": "GET"
}
```

#### Streamable HTTP
```python
{
    "name": "http_stream",
    "call_template_type": "streamable_http",
    "url": "https://api.example.com/stream",
