Mempool.space

Integrates with mempool.space APIs to provide real-time Bitcoin network data including transaction details, block information, address balances, mining statistics, and fee recommendations for developers and traders.

A Bitcoin mempool and blockchain data MCP server built by Alexandre Sanlim that provides comprehensive access to mempool.space APIs through a clean Domain-Driven Design architecture. The server exposes 30+ tools for querying Bitcoin network data including transaction details, block information, address balances, mining pool statistics, fee recommendations, and mempool status, with support for both public mempool.space and local Bitcoin node instances like Umbrel. Built with TypeScript and organized into distinct application, domain, infrastructure, and interface layers, it's particularly useful for Bitcoin developers, analysts, and traders who need programmatic access to real-time blockchain data without managing API complexity directly.
