get_dax_measures
AI agents call get_dax_measures to retrieve information from PBIXRay 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 metadata about DAX measures (calculations/business logic) from Power BI files. It performs no data modification, deletion, or code execution—only querying of model definitions. While the description is empty, the naming pattern and context of sibling read-only tools confirm it as a Read operation.
From the tool's definition Tool name 'get_dax_measures' indicates retrieval of DAX measures from Power BI models. Sibling tools like 'get_dax_columns', 'get_dax_tables', 'get_metadata', and 'get_model_definition' are all read-only inspection tools.

get_dax_measures is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_dax_measures rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for get_dax_measures. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
