Swiss Groceries MCP

swissgroceries-mcp gives any MCP-compatible client (Claude Desktop, Claude Code, Cursor, Cline, Continue, VS Code) real-time access to Swiss grocery chain catalogs.

What you can ask

• "Where is milk cheapest near 8001 Zürich right now?"
• "I need milk, bread, eggs, chicken, and pasta near 8050. Where should I shop to keep costs down?"
• "What is on sale at Aldi this week?"
• "Find Coop stores within 3 km of Bern Hauptbahnhof."

Install

{
  "mcpServers": {
    "swissgroceries": {
      "command": "npx",
      "args": ["-y", "@nicktcode/swissgroceries-mcp"]
    }
  }
}

No accounts, no tokens, no API keys. The Denner adapter self-registers an anonymous client on first use; everything else uses public endpoints.

For Claude Desktop one-click install, download the .mcpb from the GitHub Releases page.

Tools

Chain coverage

Highlights

• Cross-store unit-price comparison - compares CHF/kg, CHF/l, CHF/piece across chains so multi-pack and single-bottle prices are evaluated fairly.
• Three planning strategies: single_store (fewest stops), split_cart (cheapest with stop penalty), absolute_cheapest (no penalty).
• Multipack annotation - every product exposes per-bottle/per-unit estimates derived from pack patterns like 6x1.5l.
• Category-canonicality filter - when one chain returns a real apple and another returns apple juice, the juice is dropped from the cross-chain comparison automatically.
• Resilience built in - in-memory cache, retry with exponential backoff, per-host rate limiting, and a per-host circuit breaker.
