What is Nostr MCP Server?
The Nostr MCP Server is a Model Context Protocol server that allows Large Language Models (LLMs) like Claude and Cursor to interact with the Nostr network. It acts as a bridge, providing LLMs with tools to access and utilize Nostr data.
How to use Nostr MCP Server?
To use the server, you need to install it, configure your LLM (Claude or Cursor) to connect to it, and then issue commands to the LLM that utilize the Nostr tools. The README provides detailed instructions for installation and configuration for both Claude and Cursor. Once configured, you can ask the LLM to perform actions like fetching profiles, notes, or zaps from the Nostr network.
