WHAT IT DOES

What profile-by-name does on Nostr Bray

AI agents call profile-by-name 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 profile-by-name is rated Low

This tool retrieves profile information about a contact by name. It is a straightforward lookup operation that reads data without creating, modifying, deleting, executing code, or moving money. The minimal severity reflects that profile lookups on a social/trust platform pose low risk of misuse—even if an agent probes contacts, the impact is limited to information retrieval.

From the tool's definition Tool name 'profile-by-name' and description 'Look up a contact' indicate a query/retrieval operation with no side effects.

RECOMMENDED RULE

The rule that runs profile-by-name 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 profile-by-name, this is the rule to start with:

profile-by-name Allowed

profile-by-name 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": {
    "profile-by-name": {}
  }
}

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 profile-by-name call is checked against it from then on.
