A local-first grocery price tracker that exposes read-only price history and comparison data through MCP. The server sits on top of dealwatcherer's core engine, which crawls vendor sites, normalizes prices, and stores everything locally with full source traceability. You get tools to query product price history, compare current prices across stores, and surface deals without leaving Claude. Pairs naturally with the browser extension for right-click product capture. Reach for this when you want AI-assisted shopping decisions backed by your own crawled data instead of trusting third-party APIs. No cloud roundtrip, no telemetry, just SQLite and stdio transport. Part of the "yard family" of structured-input-structured-output tools from the same author.
