Overview

AI-generated overview

DealWatch is a local-first grocery price-tracking tool whose read-only MCP server lets an assistant query tracked product prices and deal history.

What you can do
  • Query tracked products and their price history across vendors
  • Surface deal scores and alerts when a price looks worth acting on
  • Compare prices between vendors for the same product
  • Work from locally stored data, with no cloud round-trip
When to use it
Useful when you want an assistant to check whether a tracked grocery product is at a good price, or to compare vendor prices before buying, without leaving your machine.
Requirements
Runs as a local stdio process installed from the PyPI package dealwatch; desktop only, no web execution. The README describes cloning the repository and following a per-stack quickstart. No authentication, environment variables or headers are declared.
Before you install
The README describes crawling vendor sites, scheduled checks and a browser extension, so the tool may fetch product pages from third parties; review what it collects before running it. The MCP server itself is described as read-only, but the wider tool writes price history locally. No credentials are declared.

Installation

In SourceWeft

  1. Open DealWatch in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

How It Work

The repo is seven layers — exactly the seven commits in git log. New work goes in as small named PRs. No 50-file mystery commits.

LayerWhat
chore: scaffoldLicense, governance, hygiene gates, CI scaffolding.
feat(core)The primary engine. The reason dealwatcherer exists.
feat(modules)Packages, adapters, services, plugins. The second floor.
feat(contracts)Schemas, configs, public boundaries. Other code talks here.
test:Receipts. Everything in this layer must run.
feat(ops)Scripts, infra, CI helpers, build glue.
docs:Public docs surface. The pretty face.

git log reads like a building floor plan. Look once, know the whole shape.
