Manage LucasApp finances from the terminal. The CLI is built for humans, scripts, and AI agents: command output is structured JSON unless a command is explicitly interactive.

npm install -g lucasapp-cli

lucas auth login
lucas auth status
lucas auth logout

login opens LucasApp in your browser and asks you to approve a short visible code. Credentials are stored locally in ~/.config/lucas/credentials.json with owner-only permissions. logout clears the local credentials and attempts to revoke the CLI device token server-side.

Command groups: auth, accounts, transactions, transfers, subscriptions, subscription-groups, subscription-charges, settings, loans, stats, categories, exchange-rate, and ai. The ai group is intentionally limited to usage and text/image expense parsing.

List commands are intentionally agent-friendly:

• transactions list supports --account-id, --account-ids, --category-id, --category-ids, --type, --search, --min-amount, --max-amount, --from, --to, --limit, and --offset.
• transfers list supports --limit and --offset over transfer pairs. Each transfer pair still returns its two transaction rows.
• subscriptions list supports --limit, --offset, --frequency, --type, and --group-id.
• subscriptions calendar mirrors the backend monthly billing calendar, and subscription-groups exposes group list/create/update/delete/reorder.
• subscription-charges exposes generated charges, pending-charge pagination, account-scoped charges, and pay/confirm/manual-paid/revert actions.
• Investments are hidden for launch and are not exposed through the CLI.
• accounts list --include-archived includes archived accounts in the account array and adds archivedAccounts metadata. Balance/debt totals remain the active-account totals returned by LucasApp.
• exchange-rate convert --amount <n> includes a client-side convertedAmount derived from the backend rate.

Success:

{ "ok": true, "data": { "example": true } }

Error:

{
  "ok": false,
  "error": {
    "message": "Not authenticated. Run: lucas auth login",
    "statusCode": 401
  }
}

• Do not pass arbitrary local files to agent-driven commands.
• parse-expenses-image accepts only real JPG, PNG, WebP, or HEIC files and rejects symlinks, suspicious credential paths, unsupported extensions, and oversized images.
• Resource IDs are validated before building API paths.
• Backend error details are summarized by default. Set LUCAS_DEBUG=1 only while debugging locally; sensitive fields are redacted.
• Network failures return structured JSON instead of raw Node stack traces.
• The default production API is https://api.lucasapp.app.
• LUCAS_API_URL is intended for local development and advanced testing. Normal users should keep the default production URL.
• Never commit .env, .npmrc, credentials, keys, certificates, service account files, database dumps, or private fixtures.
