WHAT IT DOES

What signet-credentials does on Nostr Bray

AI agents call signet-credentials 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 signet-credentials is rated Low

The tool queries and retrieves credential metadata (tier, type, method, profession, jurisdiction, age range, expiry) about a user's Nostr identity without modifying data or executing actions. This is a Read operation.

From the tool's definition Tool performs 'List all kind 31000 Signet credentials' and 'inspect a user' — these are retrieval operations with no modification or execution capability.

RECOMMENDED RULE

The rule that runs signet-credentials 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 signet-credentials, this is the rule to start with:

signet-credentials Allowed

signet-credentials 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": {
    "signet-credentials": {}
  }
}

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 signet-credentials call is checked against it from then on.
