WHAT IT DOES

What list-bookmark does on Nostr Bray

AI agents call list-bookmark 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 list-bookmark is rated Low

This tool lists or retrieves bookmarks stored per NIP-51 standard. Although the description says 'Manage bookmarks', the specific operation exposed here is 'list-', which is a read-only query with no side effects. No data is created, modified, deleted, or financial value exchanged. Blast radius is minimal: worst case, an agent reads a user's bookmark collection.

From the tool's definition Tool name 'list-bookmark' and description 'Manage bookmarks' indicate a query/retrieval operation. The 'list-' prefix is characteristic of Read operations that retrieve data without modification.

RECOMMENDED RULE

The rule that runs list-bookmark 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-bookmark, this is the rule to start with:

list-bookmark Allowed

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "list-bookmark": {}
  }
}

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 list-bookmark call is checked against it from then on.
