Bitcoin MCP
Plugs your AI agent directly into Bitcoin through the Satoshi API or your own node. Get smart fee recommendations, analyze mempool congestion, decode transactions with inscription detection, track mining difficulty and hashrate, and check address balances. The 49 tools cover everything from estimating exact transaction costs before broadcast to comparing fee tiers across confirmation targets. Zero configuration to start with the hosted API, and you can switch to local Bitcoin Core when you need it. Includes prebuilt prompts like "should I send this transaction now or wait" that call the fee intelligence tools and give you a clear answer with savings breakdowns.
