What it is
A Streamable HTTP MCP server generated from Maestro's Bitcoin API. It exposes blocks, transactions and addresses to an assistant, and Maestro runs hosted endpoints for both mainnet and testnet4 so you do not have to deploy anything.
Requirements
A Maestro API key from docs.gomaestro.org, used to authenticate against the hosted endpoint. To run your own instance you need Bun 1.0 or higher: bun install, bun run build, then bun run start:http, with the key and API_BASE_URL set in .env. A self-hosted server listens on the port in .env, defaulting to 3000, and serves MCP at /mcp.
Setup effort
Add the hosted endpoint plus a key — paste it into your client, then supply credentials
