NIP-05 Identity Service

Get a yourname@jorgenclaw.ai verified Nostr identity — registered by an AI agent over Lightning.

How to register:

  1. Open any Nostr client (Amethyst, Primal, Damus, etc.)

  2. DM this npub: npub16pg5zadrrhseg2qjt9lwfcl50zcc8alnt7mnaend3j04wjz4gnjqn6efzc

  3. Send the message: register yourname

  4. Pay the Lightning invoice that arrives in reply (1,000 sats)

  5. Done — yourname@jorgenclaw.ai resolves immediately on all Nostr clients

Uses NIP-17 gift-wrapped DMs. Works with all modern Nostr clients.

Features

  • NIP-46 bunker mode — Set NOSTR_BUNKER_URI once, all signing routes through your bunker

  • Direct key mode — Pass privateKey per-tool call (backwards compatible)

  • 23 tools — Notes, profiles, social actions, DMs (NIP-04/44), relay lists, zaps, fetch

  • MCP native — Works with any MCP-compatible client

Quick Start

npm install
npm run build

Direct key mode (no bunker)

node dist/index.js

Tools require privateKey parameter on each signing call.

Bunker mode (recommended)

NOSTR_BUNKER_URI="bunker://<pubkey>?relay=wss://relay.example.com&secret=abc" node dist/index.js

All signing tools use the bunker. privateKey parameter becomes optional.
