MOST DANGEROUS TOOLS

Critical Risk

The most dangerous Nostr Tools for AI Agents tools

Destructive · High deleteEvent This tool irreversibly removes events from Nostr. Execute · High signNostrEvent Signing a Nostr event is an active cryptographic operation that authorizes and commits an event for publication on the Nostr network. Execute · Medium signNote Signing a note is more than a read operation; it performs a cryptographic action that produces an authenticated artifact ready to be broadcast to the Nostr network. Write · Medium createNostrEvent This tool creates unsigned Nostr events, which is a reversible write operation—it generates new data objects but does not execute, delete, or finalize them on the network.

22 of Nostr Tools for AI Agents's 23 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control Nostr Tools for AI Agents

PolicyLayer is an MCP gateway — it sits between your AI agents and Nostr Tools for AI Agents, and nothing reaches the server without passing your rules. These are the rules we recommend:

Deny destructive operations

{
  "deleteEvent": {
    "deny_if": [
      {
        "conditions": [],
        "on_deny": "Blocked by default. Requires approval."
      }
    ]
  }
}

Destructive tools should never be available to autonomous agents without human approval.

Rate limit write operations

{
  "createNostrEvent": {
    "limits": [
      {
        "counter": "createnostrevent_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "getSignerInfo": {
    "limits": [
      {
        "counter": "getsignerinfo_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

Controls API costs and prevents retry loops from exhausting upstream rate limits.

FAQ

Questions about Nostr Tools for AI Agents

Can an AI agent delete data through the Nostr Tools for AI Agents MCP server? +

Yes. The Nostr Tools for AI Agents server exposes 1 destructive tools including deleteEvent. These permanently remove resources with no undo. PolicyLayer blocks destructive tools by default so they never reach the upstream server.

How do I prevent bulk modifications through Nostr Tools for AI Agents? +

The Nostr Tools for AI Agents server has 19 write tools including createNostrEvent, createNote, createProfile. Set a rate limit in your policy -- for example, 10 calls per hour prevents an agent from making more than 10 modifications per hour. PolicyLayer enforces this at the gateway, before calls reach Nostr Tools for AI Agents.

How many tools does the Nostr Tools for AI Agents MCP server expose? +

23 tools across 3 categories: Destructive, Read, Write. 1 are read-only. 22 can modify, create, or delete data.

How do I enforce a policy on Nostr Tools for AI Agents? +

Register the Nostr Tools for AI Agents MCP server in PolicyLayer, apply the suggested rules above (adjust the limits to your use case), and point your AI client at the PolicyLayer proxy URL instead of the server directly. Your agents keep the same tools; PolicyLayer evaluates every call against policy before it executes. Nothing to install, live in minutes.

Enforce policy on every Nostr Tools for AI Agents tool call.

Deterministic rules across all 23 Nostr Tools for AI Agents tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.
