WHAT IT DOES

What group-admins does on Nostr Bray

AI agents call group-admins to retrieve information from Nostr Bray without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why group-admins is rated Low

This tool retrieves administrative metadata from a Nostr relay (kind 39001 is a standard Nostr event type for group admin lists). It performs a read-only query with no side effects, no data modification, no code execution, and no destructive or financial operations. The blast radius of misuse is minimal — an AI agent could enumerate admins but cannot change roles, permissions, or data.

From the tool's definition Tool description explicitly states 'Read the verified relay-generated kind 39001 admin list and role labels' — the verb 'Read' and action of retrieving/querying an admin list with no modification capability.

RECOMMENDED RULE

The rule that runs group-admins 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 group-admins, this is the rule to start with:

group-admins Allowed

group-admins is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "group-admins": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Nostr Bray, apply this rule, and every group-admins call is checked against it from then on.
