THE RISK

Critical Risk

Why delete-category needs a policy

Deleting a category cannot be undone and results in permanent data loss. This is a destructive operation affecting dashboard organization and potentially associated data. Severity is high rather than critical because the blast radius is typically limited to a single category rather than system-wide infrastructure, though the exact impact depends on how many charts or dependent resources are affected.

From the tool's definition Tool name is 'delete-category' and description states 'Delete a category'. The verb 'delete' indicates irreversible removal of data.

POLICY

How to control delete-category

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

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "delete-category"
  ]
}

delete-category 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 PI API MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
