Configuration

Variable	Required	Secret	Description
LFM_NOSTR_RELAYS	—	—	Comma-separated relay URLs to query. Only add a relay here if it gates writes the way relay.lightning.fm does (allowlisted artists only) — an unrestricted public relay hands back every other app's kind-31337 events too, not just Lightning FM's.
LFM_BLOSSOM_URL	—	—	Blossom server audio/image hashes resolve against.
LFM_CACHE_TTL_MS	—	—	How long a fetched catalog/profile/now-playing snapshot is reused, in milliseconds, before the next tool call re-queries the relays.
