# Bitcoin MCP — BTC address validation, transaction decoding, blockchain queries

Queries the Bitcoin blockchain for address balances, transaction inputs/outputs, and Lightning Network data. Can be pointed at a public node or your own Bitcoin Core instance.

## Install

```
npm i -g bitcoin-mcp
```

## Configuration

```json
{
  "mcpServers": {
    "bitcoin": {
      "command": "bitcoin-mcp"
    }
  }
}
```

Configure with your node's RPC endpoint if self-hosting Bitcoin Core. The default uses a public node.

## What it adds

Claude validates BTC addresses, decodes transaction inputs and outputs (UTXO model), queries confirmed and unconfirmed transactions, and traces Lightning Network channel data. The core BTC wallet tracing capability — following funds through the UTXO graph, identifying change-address clusters, and building the transaction chain for evidence documentation.
