Overview

A Nostr MCP server that enables AI models to interact with Nostr, allowing them to post notes and interact with the freedom of speech protocol. The server provides a Model Context Protocol (MCP) compliant API for AI integration, enabling features like posting notes, connecting to multiple relays, and sending Lightning zaps. It is designed to promote censorship resistance, even for large language models (LLMs).

Key features

Post notes to Nostr network
Connect to multiple relays
MCP-compliant API for AI integration
Send Lightning zaps to Nostr users (WIP)
