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.
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.
Signing daemon — holds the nsec in kernel memory, exposes signing via Unix socket
MCP server — stateless, handles tool calls and Lightning payment flow
