WHAT IT DOES

What label-remove does on Nostr Bray

AI agents call label-remove to permanently remove resources in Nostr Bray, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

RISK

Why label-remove is rated Critical

This tool permanently deletes label events authored by the user. Deletion is irreversible and cannot be undone, fitting the Destructive category. Severity is high because deletion of labels could affect identity/reputation systems, trust networks, or social signals in the Nostr ecosystem, impacting multiple downstream references.

From the tool's definition Tool description states "Delete a label event" and explicitly mentions "kind 5 deletion", which in the Nostr protocol is a deletion event. The description confirms irreversible removal of data.

RECOMMENDED RULE

The rule that runs label-remove safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Nostr Bray, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For label-remove, this is the rule to start with:

label-remove Hidden

label-remove is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
