Sign out of Power BI by clearing the cached credentials.
AI agents call logout to permanently remove resources in PowerBI Analyst MCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Clearing cached credentials is an irreversible action in context — it invalidates the current authenticated session and destroys stored credential data. The user would need to re-authenticate to regain access. This is not a simple read or write; it permanently removes authentication state, which is closer to Destructive than Write.

Documented attack patterns abuse exactly the kind of access logout 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 logout:
{
"version": "1",
"default": "deny",
"hide": [
"logout"
]
}logout disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Sign out of Power BI by clearing the cached credentials. It is categorised as a Destructive tool in the PowerBI Analyst MCP MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the PowerBI Analyst MCP server in PolicyLayer and add a rule for logout: 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.
logout is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the logout 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 logout. 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.
logout 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.
