WHAT IT DOES

What identity-list does on Nostr Bray

AI agents call identity-list 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 identity-list is rated Low

The tool performs a data retrieval operation ('List') with no capability to create, modify, delete, or execute actions. It explicitly states it 'Never includes private keys', further confirming it is a safe read operation. The blast radius of misuse is minimal — an attacker gains only visibility into available identities, not the ability to compromise them or perform unauthorized actions.

From the tool's definition Tool description states 'List all known identities' and 'Returns array of { npub, purpose, index, personaName }' — a read-only query operation that retrieves and enumerates existing data without modification or side effects.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs identity-list 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 identity-list, this is the rule to start with:

identity-list Allowed

identity-list 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": {
    "identity-list": {}
  }
}

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 identity-list call is checked against it from then on.

FAQ

Questions about identity-list

What does the identity-list tool do? +

List all known identities (master + all derived). Returns array of { npub, purpose, index, personaName }. Never includes private keys. Use this to see what identities are available before switching. It is categorised as a Read tool in the Nostr Bray MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on identity-list? +

Register the Nostr Bray MCP server in PolicyLayer and add a rule for identity-list: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Nostr Bray. Nothing to install.

What risk level is identity-list? +

identity-list is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit identity-list? +

Yes. Add a rate_limit block to the identity-list rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block identity-list completely? +

Set action: deny in the PolicyLayer policy for identity-list. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides identity-list? +

identity-list is provided by the Nostr Bray MCP server (nostr-bray). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
