What search-notes does on Nostr Bray
AI agents call search-notes 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.
Why search-notes is rated Low
This tool performs a read-only search operation across Nostr notes. It queries existing data and returns results without side effects, state changes, or external execution. The optional relay specification does not change the fundamental read-only nature of the operation. Severity is low because search queries have no blast radius beyond information disclosure.
From the tool's definition Full-text search for notes (kind 1) using NIP-50. Search operations retrieve and query data without modifying, deleting, or executing external operations.
Attacks that exploit this kind of access
The rule that runs search-notes 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 search-notes, this is the rule to start with:
search-notes is read-only, so it stays allowed. 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 search-notes call is checked against it from then on.
