Or with docker compose:

docker compose up

Pass environment variables to connect to a local Bitcoin Core node or set your API key:

docker run -i -e SATOSHI_API_KEY=your-key bitcoin-mcp

Why bitcoin-mcp?

Fee intelligence that saves real money — know the cheapest time to send, compare fee tiers, estimate exact costs before broadcasting
Zero config — works instantly with the free hosted Satoshi API, or connect your own Bitcoin Core node
First Bitcoin MCP server on the Anthropic Registry

Top Use Cases
