A Model Context Protocol (MCP) server that gives LLMs like Claude tools to read public profiles, text notes, long-form content, and zaps from the Nostr network.
How to use Nostr MCP Server?
Clone the repo, install dependencies with npm install, build with npm run build, then add the server to your Claude for Desktop or Cursor MCP configuration. Once configured, ask Claude to use any of the seven Nostr tools.

Frequently asked questions
Which relays does the server use by default?
The default relays are wss://relay.damus.io, wss://relay.nostr.band, wss://relay.primal.net, wss://nos.lol, wss://relay.current.fyi, and wss://nostr.bitcoiner.social.
Can I use a custom relay for a query?
Yes, you can specify any relay by adding “using relay wss://…” to your request.
What is the default query timeout?
The server has a default 8‑second timeout; you can increase it by editing the `QUERY_TIMEOUT` value in the source code.
Are there any known limitations?
Only public keys in hex or npub format are supported, and only a subset of relays is used by default. Timeouts may occur if a relay is slow.
