AI agents call read_query_result to retrieve information from PowerBI Analyst MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries data with no side effects. It appears designed to fetch results from executed DAX queries, consistent with the 'Read' category which covers search, list, get, and fetch operations. The sibling tools 'execute_dax' handles execution while 'read_query_result' handles result retrieval, a clear separation of concerns.
From the tool's definition Tool name 'read_query_result' directly indicates retrieval functionality. No description provided, but in context of a PowerBI Analyst MCP server focused on querying semantic models, this tool retrieves previously computed query results without modifying data.
Documented attack patterns abuse exactly the kind of access read_query_result gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and PowerBI Analyst MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for read_query_result:
{
"version": "1",
"default": "deny",
"tools": {
"read_query_result": {}
}
}read_query_result is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

read_query_result. It is categorised as a Read tool in the PowerBI Analyst MCP MCP Server, which means it retrieves data without modifying state.
Register the PowerBI Analyst MCP server in PolicyLayer and add a rule for read_query_result: 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 PowerBI Analyst MCP. Nothing to install.
read_query_result 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 read_query_result 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 read_query_result. 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.
read_query_result is provided by the PowerBI Analyst MCP server (mbrummerstedt/powerbi-analyst-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from PowerBI Analyst MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
