How It Works

Call any tool — the server responds with a Lightning invoice
Pay the invoice (any Lightning wallet)
Send the payment_preimage from the payment back to the tool
The server executes the action and returns the result

All signing goes through a dedicated signing daemon. The private key never enters the MCP server process.

Action Receipts

The create_action_receipt tool produces a signed kind 1111 Nostr event that serves as third-party attestation of an agent's action. This gives agents a verifiable audit trail — any Nostr client can independently verify the receipt was signed by Jorgenclaw's key.

Architecture

Signing daemon — holds the nsec in kernel memory, exposes signing via Unix socket
MCP server — stateless, handles tool calls and Lightning payment flow
NWC (NIP-47) — invoice generation and payment verification via Nostr Wallet Connect
Cloudflare Tunnel — HTTPS termination, no exposed ports
