What privacy-open does on Nostr Bray
AI agents call privacy-open 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 privacy-open is rated Low
This tool performs a cryptographic verification operation - it reads/checks whether a given value and blinding factor match a public commitment. It has no side effects, does not write or modify data, and simply returns a boolean result. Pure read/verification operation.
From the tool's definition Verify a Pedersen commitment opening...check they match the public commitment. Returns true if the commitment is valid.

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