Overview
What is Nostr MCP Server?
Nostr MCP Server is a Model Context Protocol (MCP) server that enables AI models to interact with the Nostr decentralized social network. It allows LLMs to post notes and engage with the freedom‑of‑speech protocol.
How to use Nostr MCP Server?
Install via Smithery (npx -y @smithery/cli install @AbdelStark/nostr-mcp --client claude) or clone the repository, install dependencies (npm install), and create a .env file with your Nostr private key and relay list. Run with npm run dev (development) or npm start (production). The server exposes tools post_note and send_zap via MCP.
Key features of Nostr MCP Server
- Post notes to the Nostr network
- Connect to multiple relays at once
- MCP‑compliant API for AI integration
- Send Lightning zaps to Nostr users (work in progress)
- Server‑Sent Events (SSE) support for real‑time communication
Use cases of Nostr MCP Server
- An AI assistant publishing announcements or updates to Nostr
- Automated content distribution across Nostr relays
- Allowing LLMs to send micropayments via Lightning zaps
- Censorship‑resistant messaging from AI agents
FAQ from Nostr MCP Server
What does Nostr MCP Server do?
It acts as a bridge between MCP‑compatible AI models and the Nostr protocol, allowing models to post notes and send Lightning zaps directly to the Nostr network.
What are the runtime requirements?
Node.js version 18 or higher is required.
Do I need a Nostr private key?
Yes. You must set the NOSTR_NSEC_KEY environment variable (a nsec‑format key) to authenticate and publish notes.
Which Nostr relays does it connect to by default?
The default relays are wss://relay.damus.io, wss://relay.primal.net, and wss://nos.lol. You can configure a custom list via the NOSTR_RELAYS environment variable.
What transport modes are supported?
The server supports SSE (Server‑Sent Events) mode by default. Stdin transport mode is planned but not yet implemented.
