List all RLS (Row-Level Security) roles defined in the Power BI Desktop model
AI agents call desktop_list_rls_roles 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.
This tool retrieves metadata about RLS role definitions. While it is a Read operation (no side effects), the sensitivity is elevated to medium severity because RLS role information can reveal security architecture, user segmentation strategies, and data access control patterns that could inform further attacks or unauthorized access attempts.
From the tool's definition Tool name and description: 'List all RLS (Row-Level Security) roles defined in the Power BI Desktop model' — the verb 'list' and 'defined in' indicate retrieval/enumeration of existing configuration data without modification.
Attacks that exploit this kind of access
List all RLS (Row-Level Security) roles defined in the Power BI Desktop model. 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 desktop_list_rls_roles: 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.
desktop_list_rls_roles 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 desktop_list_rls_roles 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 desktop_list_rls_roles. 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.
desktop_list_rls_roles 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.
