Bitcoin MCP server for blockchain data access via Model Context Protocol

bitcoin-mcp

bitcoin-mcp extends AI utilities with accurate Bitcoin blockchain data based on MCP. bitcoin-mcp is a streamlined Model Context Protocol (MCP) server implementation that interfaces with Bitcoin Core (full-node) through bitcoin-cli. This bitcoin-mcp server provides Claude Desktop (or other mcp clients) with READ access to Bitcoin blockchain data WITHOUT wallet functionality.

Features

AI agent meets the most secure data ledger - Bitcoin.

• Query real-time Bitcoin blockchain information (via bitcoin-cli, but WITHOUT any wallet calls)

• Access mempool, blocks, and transaction data

• Generate custom 3D visualization of BTC blocks based on TX output values and BitFeed representation (i.e., those beautiful rectangles on mempool.space)

  

Prerequisites

• Claude Desktop (or other mcp clients)
• Python 3.10+
• Bitcoin full-node (w. bitcoin-cli)
• (Windows)

Installation

1. Clone the repo to your up-to-date btc full node machine (required for bitcoin-mcp to work)

2. Install dependencies:

pip install -r requirements.txt

3. Make sure Bitcoin Core is up-to-date and running. Configure .env and add BITCOIN_CLI_PATH so that MCP server can find bitcoin-cli

• Have this line BITCOIN_CLI_PATH=C:\\Program Files\\Bitcoin\\daemon\\bitcoin-cli in .env

4. Claude Desktop Configuration (standard setup for any mcp servers)

• update path\\to\\ to your local bitcoin-mcp folder

{
  "mcpServers": {
    "bitcoin-mcp": {
      "command": "python",
      "args": ["path\\to\\bitcoin-mcp\\bitcoin_mcp_server.py"],
      "env": {}
    }
  }
}

Test the server:

You can test the python server to see if it loads your btc full node.

python bitcoin_mcp_server.py

Available Tools

Mainly for mcp clients like Claude Desktop to utilize Bitcoin blockchain info, so NO WALLET FUNCTIONS ARE INCLUDED.

Code Structure

• bitcoin_mcp_server.py: Main server entry point
• bitcoin_connection.py: Bitcoin Core connection utilities
• bitcoin_config.py: Configuration management
• bitcoin_transactions.py: Transaction analysis utilities
• bitcoin_utils.py: Blockchain utilities
• bitcoin_analytics.py: Advanced blockchain analytics

Security Notes

• This mcp server does not include wallet functionality in Bitcoin Core (u can add those urself)
• By default, the server only binds to localhost (127.0.0.1)
• Enables read-only access to blockchain data

Example Usage

Get current blockchain information:

Tell me about the current state of the Bitcoin blockchain

Analyze a specific block:

Show me detailed information about block 800000

Get transaction fee history:

What have transaction fees been like over the past 24 hours?

Estimate hashrate:

What is the current estimated hashrate of the Bitcoin network?

Generate 3D representation (note that context length may not fit all TXs, try blocks where TX number < 20 ):
