Get table schema
AI agents call get_table_schema to retrieve information from Azure Log Analytics 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 schema metadata from Azure Log Analytics tables. It has no side effects, does not execute queries or commands, does not modify data, and does not access sensitive logs themselves—only table structure definitions. While Azure Log Analytics can contain sensitive data, schema retrieval alone poses minimal risk and is a standard exploratory operation. Classified as Read with low severity.
From the tool's definition Tool name 'get_table_schema' and description 'Get table schema' indicate retrieval of metadata about table structure. This is a read-only operation that queries schema information without modifying, executing code, deleting, or moving data.
