Tools are what make your AI Voice Agents capable. They enable your agents to perform actions, not just talk.

​
What are Tools?

Tools are functions that your AI Voice Agent can call to perform actions:
  • Custom Python Functions - Write your own functions
  • REST API Tools - Call external APIs
  • Toolkits - Group related tools together
When a user asks your AI Voice Agent to do something, the agent can:
  1. Identify which tool(s) are needed
  2. Call the tool(s) with the right parameters
  3. Use the results to provide a helpful response

​
Why Tools Matter

Without tools, your agent can only talk. With tools, your agent can:
  • Search the web
  • Access databases
  • Call APIs
  • Perform calculations
  • Execute any action you can code

Quick Example

from kuralit.tools import Toolkit

def get_weather(location: str) -> str:
    """Get weather for a location."""
    return f"Weather in {location}: sunny, 22°C"

# Create toolkit
weather_tools = Toolkit(tools=[get_weather])

# Use with agent
agent = AgentSession(
    tools=[weather_tools],
    # ...
)
