Why bulk_delete_by_criteria needs a policy

Bulk deletion operations are irreversible and can affect large datasets at once. Even without explicit description, 'bulk_delete_by_criteria' clearly denotes destructive action with high blast radius if misused by an agent (e.g., wrong criteria filter). This falls into the Destructive category as the most severe applicable classification, as deletion cannot be undone.

From the tool's definition Tool name 'bulk_delete_by_criteria' contains the verb 'delete' combined with 'bulk', indicating mass deletion of records matching specified criteria.

POLICY

How to control bulk_delete_by_criteria

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

policy.json

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

bulk_delete_by_criteria 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 Prometheus 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.
