WHAT IT DOES

What gift-wrap does on Nostr Bray

AI agents use gift-wrap to create or update resources in Nostr Bray, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Nostr Bray environment.

RISK

Why gift-wrap is rated Medium

This tool creates and signs a new encrypted/wrapped Nostr event (kind 1059) for a specific recipient. It is a Write operation — it constructs and publishes a new event — but does not delete data or execute code. The throwaway signing key adds some privacy complexity, but the core action is creating/wrapping a message.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs gift-wrap 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 gift-wrap, this is the rule to start with:

gift-wrap Rate-limited

gift-wrap stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
