Overview

What is MCP Money?

MCP Money is an MCP (Model Context Protocol) server that brings Nostr-based money management to AI assistants. Built on Nostr Development Kit (NDK) with Cashu ecash support, it enables deposit via Lightning invoices, Lightning payments, and Nostr zaps, all managed through a local wallet.

How to use MCP Money?

Install with npm install mcp-money. Run as an MCP server with npx mcp-money (default) or use CLI commands like get_balance, deposit, pay, zap, and add_mint. Provide your Nostr private key via --nsec, the NSEC environment variable, a config file, or allow auto-generation. Integration with Claude Code or Goose is done by adding MCP configuration files.

FAQ from MCP Money

How do I provide my Nostr private key?

You can supply it via the --nsec command-line argument, set the NSEC environment variable, let the wallet auto-generate a new key, or have it saved automatically in .wallet.json after first use.

What MCP tools are available?

The server exposes get_balance, get_mint_balances, deposit, pay, zap, and add_mint as tools for AI assistants.

How do I integrate MCP Money with Claude Code?

Add to your project’s MCP configuration: set command to npx and args to ["mcp-money"], or install globally and reference the binary mcp-money directly.

Where are my private keys stored?

Private keys are stored locally in the .wallet.json file created in the working directory. Security relies on file‑system access control.
