What is the Nostr MCP server?

Nostr mcp server connects Nostr to AI assistants that speak the Model Context Protocol. A Model Context Protocol (MCP) server that provides Nostr capabilities to LLMs like Claude.

What Nostr does

For the full MCP server with 48 tools, see: https://github.com/AustinKelsay/nostr-agent-interface

Tools it exposes

Once connected, the assistant can call these 2 tools directly:

  • Built — in budget monitoring** — optional Plaid-connected budget tracking for personal finance
  • Migrating — The Migrating tool exposed by this server

Installing the nostr mcp server

The server is distributed via npm as nostr-agent-interface, so most clients can run it without a manual build step. Add it to your MCP client's configuration and restart the client to pick it up — the copy-paste configs for Claude Desktop, Claude Code and Cursor are on this page.

Where it fits

Monitoring servers replace the paste-the-stack-trace ritual with an assistant that reads the real event, with all its surrounding context intact. Nostr sits in that group, and the shape of its toolset — Built, Migrating — tells you what it is really for. Worth comparing against the other monitoring security servers in this directory before you commit to one, since several overlap in scope but differ sharply in setup cost and permissions.

Practical notes

  • This server runs locally, so it operates with whatever access your machine and its credentials already have. Scope that deliberately rather than by default.
  • Maintained by austinkelsay.
  • MCP clients ask for confirmation before each tool call by default. Keep that on while you learn what the nostr mcp server actually does with your data.
  • Every entry in this directory is reviewed by hand before it goes live, and details are checked against the project's own documentation.

Frequently asked questions

It connects Nostr to MCP-compatible AI assistants such as Claude and Cursor, exposing 2 tools (Built, Migrating) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with Nostr directly.
