AI agents call bpa_validate_rules 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 is a validation and linting tool that inspects rule definitions against schema requirements and optionally returns a corrected version. It reads input, performs analysis, and outputs results without modifying any Power BI data, datasets, or configurations. It is strictly informational and diagnostic in nature.
From the tool's definition Tool performs 'Pure validation' with 'no external tool' involvement; validates JSON structure and returns validation results. With fix=true, returns a 'cleaned copy' of the input, which is a non-destructive transformation.
Attacks that exploit this kind of access
Validate a custom Best Practice Analyzer rules JSON (the public BPA rule shape): required fields (ID/Name/Category/Severity/Scope/Expression), valid Severity (1/2/3) and Scope values, duplicate IDs, destructive Delete() fixes on low-severity rules, and stray runtime-only fields. With fix=true also returns a cleaned copy. Pure validation, no external tool. 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 bpa_validate_rules: 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.
bpa_validate_rules 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 bpa_validate_rules 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 bpa_validate_rules. 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.
bpa_validate_rules 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.
