Common questions
Is Kronan MCP safe?
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
You need to fill in: KRONAN_ACCESS_TOKEN
Does it run on my computer or in the cloud?
It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).
Is it still maintained?
The GitHub repo last changed –, and the latest version (1.0.1) reached the registry 7 months ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

Tools
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 |
Install
npm install -g kronan-mcpOr run directly with npx (no install needed):
npx kronan-mcpGetting a token
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_.
Usage with Claude Code
Add to your project's .claude/settings.local.json or global ~/.claude/settings.json:
{"mcpServers": { "kronan": { "command": "npx", "args": ["kronan-mcp"], "env": { "KRONAN_ACCESS_TOKEN": "act_your_token_here" } } } }
Then ask Claude things like:
- "Search for milk on Krónan"
- "What's in my shopping note?"
- "Add 2x of SKU 02500188 to my checkout"
- "Show my recent orders"
Architecture
src/├── client.ts HTTP client wrapping all Krónan API endpoints ├── index.ts MCP server registering tools via @modelcontextprotocol/sdk └── types.ts TypeScript interfaces matching the OpenAPI schema
Auth is Authorization: AccessToken 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.
