Gets the SQL endpoint connection string for a specified Fabric Lakehouse.
AI agents call get_lakehouse_sql_connection_string to retrieve information from Semantic Model MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and returns connection string information, which is a read-only operation with no side effects. However, the connection string itself is sensitive authentication material that could be misused if obtained by an unauthorized agent to connect to backend systems, elevating severity from low to medium.
From the tool's definition The tool name and description indicate it 'Gets the SQL endpoint connection string for a specified Fabric Lakehouse' — a retrieval operation that queries configuration data without modifying anything.
