How to Set Up and Use Bitcoin

The Bitcoin MCP Server connects AI assistants to the Bitcoin blockchain and Lightning Network, enabling real-time queries of blockchain data and Lightning invoice operations without any API keys for read-only functions. It exposes tools for generating Bitcoin key pairs, validating addresses, decoding raw transactions, fetching the latest block, and looking up transactions by ID. For Lightning Network functionality, it integrates with LNBits wallets to decode and pay BOLT11 invoices, making it useful for developers building Bitcoin-aware AI workflows.

Prerequisites

  • Node.js 18+ installed (for npx execution)
  • An MCP-compatible client such as Claude Desktop or Goose
  • LNBits instance and API keys (only required for Lightning Network payment features)
  • No Bitcoin node required — blockchain data is fetched from public APIs
1

Install the Bitcoin MCP server

The server is available as an npm package and can be run directly with npx. No global installation is required for basic use.

npx -y bitcoin-mcp@latest
2

Add to Claude Desktop configuration

Edit your Claude Desktop config file to register the bitcoin-mcp server. On macOS: ~/Library/Application Support/Claude/claude_desktop_config.json. On Windows: %APPDATA%\Claude\claude_desktop_config.json.

{
  "mcpServers": {
    "bitcoin-mcp": {
      "command": "npx",
      "args": ["-y", "bitcoin-mcp@latest"]
    }
  }
}
3

Configure Lightning Network (optional)

To enable Lightning Network features such as paying invoices, provide your LNBits credentials. Obtain the admin and read keys from your LNBits wallet's API info page.

{
  "mcpServers": {
    "bitcoin-mcp": {
      "command": "npx",
      "args": ["-y", "bitcoin-mcp@latest"],
      "env": {
        "LNBITS_URL": "https://demo.lnbits.com",
        "LNBITS_ADMIN_KEY": "your_admin_key",
        "LNBITS_READ_KEY": "your_read_key"
      }
    }
  }
}
4

Restart Claude Desktop

Fully quit and relaunch Claude Desktop so the new MCP server configuration is loaded. Look for the hammer icon in the input bar to confirm tools are available.

5

Verify with a blockchain query

Ask Claude to fetch the latest Bitcoin block. The server will call the blockchain API and return current block height, hash, and timestamp.

Bitcoin Examples

Client configuration

Minimal configuration for Claude Desktop without Lightning Network features.

{
  "mcpServers": {
    "bitcoin-mcp": {
      "command": "npx",
      "args": ["-y", "bitcoin-mcp@latest"]
    }
  }
}

Prompts to try

Try these queries once the server is connected to Claude Desktop.

- "What is the latest Bitcoin block number and when was it mined?"
- "Generate a new Bitcoin key pair with address for me"
- "Validate this Bitcoin address: bc1qxy2kgdygjrsqtzq2n0yrf2493p83kkfjhx0wlh"
- "Decode this raw Bitcoin transaction and explain what it does"
- "Decode this Lightning invoice and show the amount and description"

Troubleshooting Bitcoin

npx bitcoin-mcp fails with 'command not found' or package not found

Use the correct package name: 'npx -y bitcoin-mcp@latest' (not 'npx bitcoin'). Ensure Node.js 18+ is installed by running 'node --version'.

Lightning Network tools return authentication errors

Verify your LNBits URL is reachable and that LNBITS_ADMIN_KEY and LNBITS_READ_KEY are set correctly in the env block of your MCP config. Obtain keys from your LNBits wallet at Settings → API Info.

Blockchain queries return stale or no data

The server fetches from public blockchain APIs. Transient network failures or rate limiting may cause empty responses. Retry after a moment, or check your internet connection.
