​
Overview

Tools enable agents to perform actions beyond text generation. They can execute code, search the web, access APIs, and integrate with external systems to accomplish complex tasks.

​
Key Features

  • Multiple Tool Types: Custom, MCP, Model Provider, and Ready-to-Use tools
  • Flexible Configuration: Control execution behavior, caching, and retries
  • Type Safety: Automatic schema generation from Python type hints
  • Parallel Execution: Run multiple tools simultaneously for better performance

​
Supported Tool Types

The tools list accepts any combination of:
TypeExampleRegistered As
Function tool@tool decorated functionFunction name
ToolKit instanceDataProcessor()All @tool methods
Class instanceCalculator()All public methods
Agent instanceanalyzer_agentask_{agent_name}
MCP HandlerMCPHandler(...)All MCP-provided tools

​
Example

Create your own tools using Python functions or classes. Perfect for business logic, API integrations, and domain-specific functionality. 
from upsonic import Agent, Task
from upsonic.tools import tool

@tool
def calculate_discount(price: float, discount_percent: float) -> float:
    """Calculate the final price after applying a discount."""
    return price * (1 - discount_percent / 100)

# Create agent and task
agent = Agent("anthropic/claude-sonnet-4-5")
task = Task(
    description="Calculate 20% discount on $100",
    tools=[calculate_discount]
)

# Execute task
result = agent.print_do(task)
print("Result:", result)
