Tools
This server runs locally, so its tools are listed by your MCP client once it starts.
Environment variables
| Name | Description |
|---|---|
LND_REST_HOSTOptional | 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_MACAROONOptional, secret | Hex-encoded macaroon for LND (use a pay-scoped macaroon in production). Required with LND_REST_HOST. |
NWC_URIOptional, secret | Nostr Wallet Connect string — easiest setup, works with CoinOS, Alby Hub, Zeus, and more. Alternative to LND. |
LNBITS_URLOptional | LNbits instance URL (pair with LNBITS_ADMIN_KEY). Alternative wallet. |
LNBITS_ADMIN_KEYOptional, secret | Admin API key for LNbits. Required with LNBITS_URL. |
PHOENIXD_URLOptional | Phoenixd HTTP API URL (pair with PHOENIXD_PASSWORD). Alternative wallet. |
PHOENIXD_PASSWORDOptional, secret | HTTP password for Phoenixd. Required with PHOENIXD_URL. |
BUDGET_SATSOptional | 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_TOKENOptional, secret | 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. |
