WHAT IT DOES

What remove_role_from_user does on Dataverse MCP Server

AI agents call remove_role_from_user to permanently remove resources in Dataverse MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

THE RISK

Critical Risk

Why remove_role_from_user needs a policy

Removing a security role from a user is an irreversible access-control change (until manually re-assigned) that revokes permissions. This is effectively a destructive operation on an authorization record — it cannot auto-recover and could immediately lock a user out of critical resources. Severity is high because misuse by an AI agent could disrupt user access across enterprise Dataverse environments.

POLICY

How to control remove_role_from_user

PolicyLayer is an MCP gateway — it sits between your AI agents and Dataverse MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for remove_role_from_user:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "remove_role_from_user"
  ]
}

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