WHAT IT DOES

What generate_directlake_tmsl_template does on Semantic Model MCP Server

AI agents use generate_directlake_tmsl_template to create or update resources in Semantic Model MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Semantic Model MCP Server environment.

WHY IT NEEDS A POLICY

Why generate_directlake_tmsl_template needs a policy

Generating a TMSL template creates or produces a new artifact (model definition template) that could be used to modify semantic models. This is a Write operation rather than Read (it produces new content) or Execute (it does not immediately run queries or commands, but produces configuration).

From the tool's definition Tool name contains 'generate' and 'template' suggesting creation of TMSL (Tabular Model Scripting Language) configuration. TMSL is used to define and modify semantic models in Microsoft Fabric/Power BI.
