Nostr MCP Server

Example Use Cases

• 1

  Read and aggregate Nostr user data and posts (profiles, kind-1 notes, long-form notes) and analyze zap receipts.

• 2

  Create, sign, and publish authenticated Nostr notes and manage user profiles and keypairs programmatically.

• 3

  Perform anonymous operations or Lightning interactions (prepare anonymous zaps, generate invoices, post anonymous notes) and convert/analyze NIP-19 entities.

Description

This project implements 18 MCP tools to let language models interact with the Nostr protocol: reading profiles and notes, creating/updating profiles, creating/signing/publishing notes, preparing and sending zaps (including anonymous zaps), and converting/analyzing NIP-19 entities. It integrates with Claude for Desktop, Cursor, and Goose, and uses a default set of relays and the snstr library for cryptographic operations. The server supports both hex and npub/nsec formats, offers caching and validation for zaps, and includes a comprehensive test suite and ephemeral relay for integration testing. It's useful for automating Nostr workflows from agents while preserving options for authenticated or anonymous posting.
