# Tool Use

> Add WebSearchTools to a Claude agent running on Azure AI Foundry.

```python tool_use.py theme={null}
"""Run `uv pip install ddgs` to install dependencies."""

import asyncio

from agno.agent import Agent
from agno.models.azure.claude import Claude
from agno.tools.websearch import WebSearchTools

# ---------------------------------------------------------------------------
# Create Agent
# ---------------------------------------------------------------------------

agent = Agent(
    model=Claude(id="claude-sonnet-4-6"),
    tools=[WebSearchTools()],
    markdown=True,
)

# String syntax alternative:
# agent = Agent(model="azure-foundry-claude:claude-sonnet-4-5", tools=[WebSearchTools()], markdown=True)

# ---------------------------------------------------------------------------
# Run Agent
# ---------------------------------------------------------------------------
if __name__ == "__main__":
    # --- Sync ---
    agent.print_response("Whats happening in France?")

    # --- Sync + Streaming ---
    agent.print_response("Whats happening in France?", stream=True)

    # --- Async + Streaming ---
    asyncio.run(agent.aprint_response("Whats happening in France?", stream=True))
