A Model Context Protocol (MCP) server that provides Nostr capabilities to AI agents
A Nostr MCP (Model Context Protocol) server with NIP-46 remote signing support. Private keys never need to touch the AI context window.
Connect directly without running locally:
https://nostr.jorgenclaw.ai/mcp
Transport: Streamable HTTP (MCP spec 2025-03-26) — compatible with Claude Desktop, Cursor, Glama, Smithery, and any MCP client.
Legacy SSE endpoint (backward compat): https://nostr.jorgenclaw.ai/sse
Get a yourname@jorgenclaw.ai verified Nostr identity — registered by an AI agent over Lightning.
How to register:

NOSTR_BUNKER_URI once, all signing routes through your bunkerprivateKey per-tool call (backwards compatible)npm install
npm run build
node dist/index.js
Tools require privateKey parameter on each signing call.
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.
