Install

npm install -g kronan-mcp

Or run directly with npx (no install needed):

npx kronan-mcp

Getting 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 <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.
