Why delete_series_by_uid needs a policy

The 'delete' verb unambiguously signals a destructive operation that cannot be undone. Without additional context from the description (which is empty), the naming convention strongly implies permanent data removal. While confidence is not maximum due to the missing description, the destructive nature of deletion operations warrants 'Destructive' classification over 'Write'.

From the tool's definition Tool name 'delete_series_by_uid' contains the verb 'delete', which indicates irreversible removal of data. The 'by_uid' parameter suggests targeting specific series records in AWS services (likely time-series or monitoring data).

POLICY

How to control delete_series_by_uid

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

policy.json

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

delete_series_by_uid 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 AWS — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
