VertiPaq-style storage analysis: per-table row counts (exact via DAX COUNTROWS), column counts, and best-effort sizes, ranked to find the biggest/most expensive tables for optimization.
AI agents call analyze_model_storage to retrieve information from Power BI MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves and reports statistics about Power BI model storage characteristics. It uses DAX queries to count rows and analyze table properties, which are informational reads with no side effects. The analysis is designed for optimization insights only, with no capability to modify, delete, or execute external operations.
From the tool's definition Tool performs 'storage analysis' with 'per-table row counts', 'column counts', and 'sizes' to 'find the biggest/most expensive tables for optimization'.
Attacks that exploit this kind of access
VertiPaq-style storage analysis: per-table row counts (exact via DAX COUNTROWS), column counts, and best-effort sizes, ranked to find the biggest/most expensive tables for optimization. It is categorised as a Read tool in the Power BI MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Power BI MCP Server MCP server in PolicyLayer and add a rule for analyze_model_storage: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Power BI MCP Server. Nothing to install.
analyze_model_storage 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 analyze_model_storage 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 analyze_model_storage. 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.
analyze_model_storage is provided by the Power BI MCP Server MCP server (sulaiman013/powerbi-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
