MCP server for the Krónan grocery store API. Claude can browse products, manage shopping notes, handle checkout, and track orders from Krónan's Snjallverslun (smart store) in Iceland.
25 tools over the Model Context Protocol:
| Category | Tools |
|---|---|
| Products | search_products, get_product, get_category_products, list_categories |
| Checkout | get_checkout, add_checkout_lines |
| Orders | list_orders, get_order, delete_order_lines, set_order_substitution, lower_order_quantity |
| Shopping notes | get_shopping_note, add_shopping_note_line, change_shopping_note_line, reorder_shopping_note_lines, delete_shopping_note_line, set_line_completion, clear_shopping_note, check_store_order_eligibility, apply_store_product_order, list_archived_lines, delete_archived_line |
| Product lists | list_product_lists, create_product_list, get_product_list, update_product_list, delete_product_list, clear_product_list, sort_product_list, update_product_list_item |
| Purchase stats | list_purchase_stats, set_purchase_stat_ignored |
| Account | get_me |
Or run directly with npx (no install needed):
Tokens are created in the Krónan Snjallverslun user settings. You need an account with Audkenni (Iceland's electronic ID) login. Go to your user or customer group settings page and create an access token. Tokens are prefixed with act_.
Add to your project's .claude/settings.local.json or global ~/.claude/settings.json:
Then ask Claude things like:
Auth is Authorization: AccessToken <token> on every request. Rate limit is 200 requests per 200 seconds per user. The client detects 429 responses and tells the caller to wait.
All prices are integers in ISK (no decimals). 230 means 230 kr.
Errors go through a typed KronanApiError with status codes. The token is scrubbed from error messages so it doesn't leak to the LLM. Auth failures and rate limits get their own user-facing messages.
set_order_substitution and set_line_completion use read-then-toggle patterns. They're not idempotent. Don't retry on timeout without checking current state first.
Full OpenAPI schema at openapi-schema.yaml.
31 tests on the HTTP client: constructor validation, error paths (429, timeouts, JSON parse failures), token scrubbing, toggle method validation, eligibility endpoint edge cases.
