WHAT IT DOES

What dispatch-refuse does on Nostr Bray

AI agents use dispatch-refuse 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 dispatch-refuse is rated Medium

This tool sends a refusal message to a sender, which is a reversible communication action (Write). It creates/posts a response message on the Nostr network. No data is deleted, no code is executed, and no financial transaction occurs. The blast radius is low since it only sends a refusal notification.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs dispatch-refuse 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 dispatch-refuse, this is the rule to start with:

dispatch-refuse Rate-limited

dispatch-refuse 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.
