Diagnose a dataset
AI agents call refresh_doctor 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.
Diagnosing a dataset involves querying its state and properties to identify issues—a non-destructive, informational action. This aligns with Read category tools like 'analyze_model_storage' and 'audit_ai_readiness' visible among sibling tools. Even if the tool internally performs queries or inspections, no side effects occur on the dataset itself.
From the tool's definition Tool name is 'refresh_doctor' with description 'Diagnose a dataset'. The verb 'diagnose' indicates analysis and inspection of a dataset's health/status, which is a read-only operation. No data is modified, deleted, or external operations are triggered.
Attacks that exploit this kind of access
Diagnose a dataset. 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 refresh_doctor: 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.
refresh_doctor 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 refresh_doctor 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 refresh_doctor. 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.
refresh_doctor 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.
