A Model Context Protocol (MCP) server that provides Bitcoin blockchain data and analysis tools through free data sources.

• Real-time blockchain data from Blockstream.info API
• Bitcoin price and market data from CoinGecko API
• Network metrics and fee estimates from Mempool.space API
• UTXO analysis and basic transaction pattern detection
• Data caching for improved performance and reduced API load

• get_block: Retrieve block information by hash or height
• get_transaction: Get transaction details by TXID
• get_address: View address information, balance, and transaction history
• get_utxos: Retrieve unspent transaction outputs for an address

• get_price_data: Current Bitcoin price and market metrics
• get_historical_price: Historical price data for specified time periods

• get_network_metrics: Bitcoin network health metrics
• analyze_fee_landscape: Current fee recommendations and analysis
• analyze_mempool_state: Mempool congestion analysis

• analyze_utxo_distribution: UTXO distribution analysis for multiple addresses
• trace_coin_lineage: Basic tracing of coin movement
• detect_transaction_patterns: Identify common transaction patterns

# Clone the repository
git clone https://github.com/myownipgit/bitcoin-data-mcp.git
cd bitcoin-data-mcp

# Install dependencies
npm install

# Build the TypeScript code
npm run build

# Start the MCP server
npm start

The server runs on stdio, which allows it to be used as a plugin for AI models and tools that support the Model Context Protocol.

This MCP server can be integrated with Claude Desktop to give Claude direct access to Bitcoin blockchain data without requiring internet access from Claude itself.

1. Start your Bitcoin MCP Server:

   npm start

2. In Claude Desktop:

   • Open Settings
   • Navigate to the "Tools" or "MCP Connections" section
   • Add a new MCP connection by clicking "Add Tool"
   • Name: "Bitcoin Data MCP"
   • Connection Type: "stdio"
   • Command: The full path to the server launch command, e.g., /path/to/bitcoin-data-mcp/dist/server.js
   • Click "Save"

3. Claude will now have access to all the Bitcoin data tools provided by this server

4. Example query to Claude: "What's the current Bitcoin price and network congestion level?"

This integration allows Claude to access real-time Bitcoin data and perform analysis without needing internet access itself, as your local MCP server handles all API calls to Blockstream, CoinGecko, and Mempool.space.

# Run in development mode (build and start)
npm run dev

• Blockstream.info API
• CoinGecko API
• Mempool.space API
