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


# Example 1: Include specific Postgres functions (default behavior - all functions included)
agent = Agent(
    tools=[
        PostgresTools(
            host="localhost",
            port=5532,

            password="ai",
            table_schema="ai",

# Example 2: Include only read-only operations

# Example 3: Exclude dangerous operations
