AI agents call list_apps 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 a list of apps (likely Power BI apps) with no modification, deletion, or execution of code. It fits the Read category as a passive information retrieval operation. Confidence is slightly reduced due to the empty description, but the naming convention and server context provide strong supporting evidence.
From the tool's definition Tool name 'list_apps' and server context describing browsing/reading operations (browse workspaces, tables, measures). Sibling tools include list_datasets, list_tables, list_measures—all read operations.
Documented attack patterns abuse exactly the kind of access list_apps 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 list_apps:
{
"version": "1",
"default": "deny",
"tools": {
"list_apps": {}
}
}list_apps is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

list_apps. 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 list_apps: 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.
list_apps 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 list_apps 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 list_apps. 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.
list_apps 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.
