WHAT IT DOES

What trust-revoke does on Nostr Bray

AI agents call trust-revoke 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 trust-revoke is rated Critical

Revoking an attestation permanently removes a trust relationship that was previously established. This is destructive because it cannot be undone (the original attestation state is lost), and misuse by an AI agent could silently destroy trust relationships between identities on the Nostr network, with potentially wide social and operational impact across a trust graph.

From the tool's definition 'Revoke a previously issued attestation' — revoking an attestation is an irreversible action that removes trust credentials previously granted

RECOMMENDED RULE

The rule that runs trust-revoke 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 trust-revoke, this is the rule to start with:

trust-revoke Hidden

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