Security scores are indicators to help you make informed decisions, not guarantees. Always review permissions before connecting any MCP server.
This plugin requests these system permissions. Most are normal for its category.
Set these up before or after installing:
Environment variable: KRONAN_ACCESS_TOKEN
Add this to your MCP configuration file:
{
"mcpServers": {
"io-github-sandsower-kronan-mcp": {
"env": {
"KRONAN_ACCESS_TOKEN": "your-kronan-access-token-here"

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 |
npm install -g kronan-mcp
Or run directly with npx (no install needed):
npx kronan-mcp
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:
{
"mcpServers": {
"kronan": {
"command": "npx",
"args": ["kronan-mcp"],
"env": {
"KRONAN_ACCESS_TOKEN": "act_your_token_here"
}
}
}
}
Then ask Claude things like:
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 <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.

npm run dev # Watch mode (recompiles on change)

31 tests on the HTTP client: constructor validation, error paths (429, timeouts, JSON parse failures), token scrubbing, toggle method validation, eligibility endpoint edge cases.
