Nostr MCP Server provides a bridge between AI assistants and the Nostr decentralized social network, enabling interaction with user profiles, posts, and Lightning Network payments. Developed by Austin Kelsay, this TypeScript implementation offers seven specialized tools for retrieving profiles, text notes, long-form content, and analyzing zap payments (Bitcoin tips) with detailed transaction information. The server features native support for npub format identifiers, NIP-57 compliant zap receipt validation, and advanced bolt11 invoice parsing, making it ideal for users who want to analyze Nostr social data, track Lightning Network payments, or search through Nostr Implementation Possibilities (NIPs) documentation without leaving their AI assistant interface.
