Configuration

Variable	Required	Secret	Description
LIBRELINKUP_EMAIL	yes	—	LibreLinkUp follower account e-mail — not the primary LibreLink account. The password is stored once via `npx mcp-freestyle-login` in the OS keychain, so it never appears in this configuration.
LIBRELINKUP_PASSWORD	—	yes	Overrides the OS keychain. Intended for CI and one-off runs; prefer `mcp-freestyle-login` so no credential lands in a config file.
LIBRELINKUP_VERSION	—	—	Pinned LibreLinkUp client version sent as the `version` header. Upstream rejects stale values — set this to the current LibreLinkUp app version if requests start failing.
LIBRELINKUP_PRODUCT	—	—	Client product identifier sent as the `product` header.
LIBRELINKUP_BASE_URL	—	—	Entry point for authentication. The regional host is discovered at login and is never configured here.
