Bitcoin MCP

Bitcoin MCP is a developer tool that brings Bitcoin blockchain queries, address validation, transaction decoding, and Lightning Network data into Claude. It's not a wallet, not a trading interface, just a clean read-only API for Bitcoin primitives wrapped in MCP format. I'd reach for this when building crypto tutorials, auditing transactions, or prototyping Bitcoin-adjacent features without spinning up a full node or hunting for API keys. The address validation alone saves time when you're sanity-checking user input or debugging payment flows. Transaction decoding is particularly useful if you're explaining Bitcoin mechanics to non-technical stakeholders or students, since you can paste a raw hex transaction and get a human-readable breakdown without leaving your chat interface. The Lightning Network integration is the standout feature here. Most Bitcoin tooling treats Lightning as an afterthought, but this server queries channel state, node info, and routing data as first-class operations. If you're building anything that touches Lightning, having this available in Claude means you can iterate on integration logic without context-switching to a separate Lightning explorer. Key generation works but feels like a teaching tool rather than production infrastructure. You can generate addresses and private keys, which is fine for demos or explaining HD wallet derivation paths, but you'd never use this for actual key management. The repo doesn't claim otherwise, which is honest. Quirks: it's read-only by design, so no broadcasting transactions or signing operations. That's a feature, not a bug, since it keeps the security surface small. The blockchain queries hit public APIs under the hood, so rate limits and availability depend on upstream providers. I didn't hit issues during testing, but it's worth knowing you're not querying a local node. Skip this if you need real-time mempool monitoring, historical UTXO set analysis, or anything that requires a full archival node. Also skip if you're just dabbling with crypto concepts, the specificity here assumes you already know what a UTXO is. But if you're teaching Bitcoin, building a block explorer prototype, or debugging Lightning channels, this is a solid addition to Claude Desktop.
