```python theme={null}
from crewai_tools import MySQLTool, QdrantVectorSearchTool, NL2SQLTool

# Create database tools
mysql_db = MySQLTool()
vector_search = QdrantVectorSearchTool()
nl_to_sql = NL2SQLTool()

# Add to your agent
agent = Agent(
    role="Data Analyst",
    tools=[mysql_db, vector_search, nl_to_sql],
    goal="Extract insights from various data sources"
)
