What nip-read does on Nostr Bray
AI agents call nip-read 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 nip-read is rated Low
This tool retrieves and filters data from Nostr relays without modifying, executing, or deleting anything. It is a straightforward read operation querying community NIPs (Nostr Improvement Proposals) based on optional filters. Even if misused by an AI agent, it cannot cause harm beyond potential information disclosure, which is a low-severity risk.
From the tool's definition Tool name 'nip-read' and description 'Fetch community NIPs' explicitly indicates a retrieval operation. The verbs 'Fetch' and 'Filter' are non-destructive queries with no side effects.

The rule that runs nip-read 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 nip-read, this is the rule to start with:
nip-read 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 nip-read call is checked against it from then on.
