Connects Claude to Blockstream's Esplora API for querying Bitcoin mainnet and testnet data. You get eight tools covering the essentials: current block height, block and transaction lookups by hash or height, address summaries with balance and transaction history, mempool stats, and fee estimates by confirmation target. Useful when you need to verify transactions, check address activity, or pull live fee recommendations without leaving your AI workflow. Part of Pipeworx's gateway setup, so you can either run it standalone or bundle it with their 250+ source collection.
