bolthub MCP Server

Connect this server

This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

This one needs environment variables set before it will start: LND_REST_HOST (LND REST API URL (recommended wallet; pair with LND_MACAROON). A wallet is optional — without one, free tools and marketplace search still work; paid calls return their payment challenge.), LND_MACAROON (Hex-encoded macaroon for LND (use a pay-scoped macaroon in production). Required with LND_REST_HOST.), NWC_URI (Nostr Wallet Connect string — easiest setup, works with CoinOS, Alby Hub, Zeus, and more. Alternative to LND.), LNBITS_URL (LNbits instance URL (pair with LNBITS_ADMIN_KEY). Alternative wallet.), LNBITS_ADMIN_KEY (Admin API key for LNbits. Required with LNBITS_URL.), PHOENIXD_URL (Phoenixd HTTP API URL (pair with PHOENIXD_PASSWORD). Alternative wallet.), PHOENIXD_PASSWORD (HTTP password for Phoenixd. Required with PHOENIXD_URL.), BUDGET_SATS (Maximum sats the server may spend per session (process lifetime), across ALL sources. Unset = unlimited; 0 = free tools only. The config file's budget.sat takes precedence.), BOLTHUB_ACCOUNT_TOKEN (Account token for tools that act on YOUR bolthub account (workspace, listing, audit, earnings, and node tools). Optional even for those: the connect_account tool pairs via the browser instead. Never needed to discover, call, or pay for APIs — buying is account-less.). The author declared them in the registry entry; get the values from the project itself.
