Load a Power BI (.pbix) file for analysis.
AI agents call load_pbix_file to retrieve information from Pbixray without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and prepares data for analysis without creating, modifying, or deleting content. It is a prerequisite read operation for the other metadata query tools on the server. However, severity is medium rather than low because loading a file could expose sensitive business intelligence, proprietary DAX formulas, or data schemas that an unauthorized agent might exfiltrate.
From the tool's definition Tool name 'load_pbix_file' and description 'Load a Power BI (.pbix) file for analysis' indicate file loading/reading without modification.
Documented attack patterns abuse exactly the kind of access load_pbix_file gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Pbixray, and nothing reaches the server without passing your rules. This is the rule we recommend for load_pbix_file:
{
"version": "1",
"default": "deny",
"tools": {
"load_pbix_file": {}
}
}load_pbix_file is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Load a Power BI (.pbix) file for analysis. It is categorised as a Read tool in the Pbixray MCP Server, which means it retrieves data without modifying state.
Register the Pbixray MCP server in PolicyLayer and add a rule for load_pbix_file: 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 Pbixray. Nothing to install.
load_pbix_file 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 load_pbix_file 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 load_pbix_file. 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.
load_pbix_file is provided by the Pbixray MCP server (jonaolden/pbixray-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Pbixray, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
