View DAX calculated tables.
AI agents call get_dax_tables 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.

However, it receives 'medium' severity rather than 'low' because Power BI models may contain sensitive business logic, proprietary calculations, or confidential metrics embedded in calculated table definitions, making unauthorized access a moderate risk if an AI agent…

get_dax_tables 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_tables 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_tables. 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.
