THE RISK

Critical Risk

Why replace-security-role-privileges needs a policy

The tool explicitly wipes all existing privileges on a security role and replaces them wholesale. This is irreversible in the sense that the previous privilege configuration is lost without a prior backup, and misuse could strip critical access controls from a role affecting all users assigned to it, making it high severity and Destructive in category.

From the tool's definition Replace the entire set of privileges on a role with the supplied list (ReplacePrivilegesRole). Destructive — wipes existing privileges.

POLICY

How to control replace-security-role-privileges

PolicyLayer is an MCP gateway — it sits between your AI agents and PowerPlatform MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for replace-security-role-privileges:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "replace-security-role-privileges"
  ]
}

replace-security-role-privileges disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Create a free account and register PowerPlatform MCP — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
