Why delete_case_follower needs a policy

This tool irreversibly deletes data (the follower association), matching the Destructive category definition of 'irreversibly deletes or overwrites data, or actions that cannot be undone.' While the impact is scoped (affecting only notification subscriptions for one user-case pair rather than the case itself or financial systems), it represents a destructive operation.

From the tool's definition The tool description explicitly states 'Remove a follower from a case' and 'Removes the follower association between case and user.' The action of removing an association is irreversible—the deletion cannot be undone without manual re-addition.

POLICY

How to control delete_case_follower

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

policy.json

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

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