## Why signet-challenge is rated Medium

This tool publishes a public challenge event on the Nostr network targeting a specific verifier, which is a write operation (creating a new event). However, it has high severity because it can be misused to falsely accuse or publicly defame verifiers, causing reputational harm. It is reversible in principle (events can be deleted on some relays) but the social damage from a misconduct accusation may be lasting.

From the tool's own definition: "Publish a kind 31000 challenge event against a verifier suspected of misconduct. Provide a reason code and optional supporting evidence text."

## Use case

AI agents use signet-challenge to create or update resources in Nostr Bray, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Nostr Bray environment.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Nostr Bray:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "signet-challenge": {
      "limits": [
        {
          "counter": "signet-challenge_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
