Search Mathem products and prepare a grocery cart from the terminal. Results are structured JSON, including ingredients, allergens, nutrition, origin, availability, and pricing when Mathem provides them.
Note
This unofficial project uses Mathem's private web endpoints, which can change without notice. It prepares and verifies the cart; checkout, payment, and delivery remain manual.
Install the bundled skill globally:
npx skills add onmax/mathem-cli --global --skill mathem-cli --yesThe skill teaches compatible coding agents to install and use the CLI, compare products, and prepare a verified cart.
Requires Node.js 24+, Google Chrome, and a Mathem account.
npx --yes mathem-cli login
npx --yes mathem-cli search "grekisk yoghurt" --limit 3
npx --yes mathem-cli product 8279
npx --yes mathem-cli add 8279

npx --yes mathem-cli update 2 8279
npx --yes mathem-cli delete 8279login opens Chrome so you can authenticate; the CLI never asks for your password. Search and cart commands write JSON to stdout, and every mutation returns the updated cart. Product IDs are preferred, but update and delete also accept a unique name fragment.
Caution
Login stores authenticated cookies in ~/.mathem-cli/session.json. Never share or commit that file; delete it and sign out from Mathem to revoke access.
