alko-mcp CLAUDE.md

alko-mcp CLAUDE.md is an instructions file for Claude Code from markusl/alko-mcp. It costs 4,176 tokens per session, scanned A, original, MIT.

Repository instructions for an MCP server that searches Alko.fi's alcohol product catalogue and provides product, store, opening-hours, stock, recommendation, and data-sync tools. MCP is a standard way for an AI assistant to use external tools.

In plain words
What is it for?
Use them when working on product searches, product details, store information, availability, recommendations, scraping, or catalogue synchronisation.
Why use it?
They explain how the server, Firestore database, web scraper, cache, and product data synchronisation fit together. This reduces guesswork when changing or running the service.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

alko-mcp CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Alko MCP Server

MCP (Model Context Protocol) server for querying the Alko.fi alcohol product catalog. Provides Claude Desktop with tools to search products, check store availability, and get recommendations.

Note: All tools return compact JSON (null values stripped) for efficient LLM processing. The LLM formats the response for human display.

Requirements

  • Node.js 24+
  • Google Cloud Firestore (or emulator for local dev)
  • Playwright (for web scraping)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
