Give your AI agent the ability to read, write, and sign on Nostr. Pay per call in sats. No accounts, no monthly fees, no surveillance.
NIP-05 subscribers at jorgenclaw.ai get 200 free calls/month — already included.
Model Context Protocol (MCP) is an open standard — think of it like a USB-C port for AI. It lets your AI assistant (Claude, ChatGPT, Cursor, and others) plug into external tools and services. When you connect an MCP server, your AI gains new abilities it didn’t have before. This server gives your AI the ability to read and write on the Nostr network: post notes, send encrypted messages, manage a profile, follow people, and more.
Tell Claude: “Post a note saying hello to my followers” — it signs and publishes.
Ask your agent to DM a contact privately — NIP-44 encrypted, end-to-end.
Update your profile, set relay lists, follow/unfollow — all through conversation.

Pay-per-call tokens are topped up by purchasing more credits. Subscribers get 200 calls reset monthly.
No. Payments go directly to the server operator (Scott Jorgensen / jorgenclaw.ai) via Lightning. No middleman holds funds.

Most AI tools require you to hand your credentials to a third party, trust their privacy policy, and accept their terms of service. This server is different. It’s built on Nostr — a protocol where your identity is a cryptographic key that you own. Your keys, your data, your social graph.
The Lightning payment model was a deliberate choice. No account signup means no email address handed over, no profile to build about you. You pay for what you use, pseudonymously, via Bitcoin. If you stop paying, nothing is owed and nothing is locked in.
This server is open-source. The code running it is the same code published at github.com/jorgenclaw/nostr-mcp-server. You can verify what it does, run your own copy, or fork it.
