What list-mute does on Nostr Bray
AI agents use list-mute 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.
Why list-mute is rated Medium
The tool creates or modifies a mute list by adding or removing entries. While 'remove' sounds destructive, mute list entries can be re-added, making this reversible. The blast radius is medium — misuse could silence legitimate contacts or expose unwanted content, but it does not delete permanent data.
From the tool's definition 'Add or remove pubkeys, event IDs, keywords, or hashtags' — modifies a mute list (NIP-51, kind 10000)
Attacks that exploit this kind of access
The rule that runs list-mute 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 list-mute, this is the rule to start with:
list-mute 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Nostr Bray, apply this rule, and every list-mute call is checked against it from then on.
