概览

AI 生成的概览

DealWatch 是一个本地优先的杂货价格追踪工具，其只读 MCP 服务器让助手查询已追踪商品的价格与优惠历史。

可以做什么: 查询已追踪商品及其跨商家价格历史
获取优惠评分与值得出手时的提醒
对比同一商品在不同商家的价格
基于本机存储的数据工作，不经过云端往返
适用场景: 适合希望让助手在购买前确认某款杂货商品价格是否合适，或比较不同商家报价，同时数据不出本机的场景。
运行要求: 以本地 stdio 进程运行，从 PyPI 包 dealwatch 安装；仅限桌面端，不支持网页执行。README 提到需克隆仓库并按各技术栈的快速开始操作。未声明任何认证、环境变量或请求头。

安装前请注意

README 提到会爬取商家网站、定时检查并提供浏览器扩展，因此可能访问第三方商品页面，运行前请确认其采集内容。MCP 服务器本身被描述为只读，但整体工具会在本地写入价格历史。未声明任何凭据。

安装

在 SourceWeft 中

打开控制台中的 DealWatch，将其添加到工作区。
为需要使用其工具的对话启用该服务。

Desktop only，通过 STDIO。 STDIO 服务会启动本地进程，因此需要 SourceWeft 桌面宿主。

其他 MCP 客户端

Track prices across vendors. Get the receipt before you check out.

What You Get

Surface	What
`dealwatcherer core`	Price-monitoring engine. Crawl, normalize, score, alert.
`dealwatcherer frontend`	Compare-first dashboard. See the deal, not the noise.
`browser extension`	Right-click any product. dealwatcherer does the rest.
`dealwatcherer worker`	Scheduled checks, alembic-backed history.
`public skills`	Drop into Claude/Codex/OpenClaw and let the agent shop.

[!IMPORTANT] Local-first by default. No silent telemetry. No cloud round-trip. Your data stays on your machine until you explicitly ship it somewhere.

Install

bash

git clone https://github.com/xiaojiou176-open/dealwatcherer.gitcd dealwatcherer# follow the per-stack quickstart in INSTALL.md or docs/

git clone https://github.com/xiaojiou176-open/dealwatcherer.gitcd dealwatcherer# follow the per-stack quickstart in INSTALL.md or docs/

Three commands. No curl | sh. No login. Read what you run.

Install break? Open your favorite agent and say "Read AGENTS.md and bootstrap dealwatcherer for me." Agent fix own brain. Long version: docs/.

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.

Layer	What
`chore: scaffold`	License, 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.

Ecosystem

dealwatcherer lives in the yard family: seven yards. one philosophy: structured input, structured output, structured proof.

Repo	What
switchyard	model & agent runtime switch board
browserclickyard	your AI clicks, your browser obeys
noteyard	your Apple Notes never really die
dealwatcherer (you here)	let prices fight, you sit and watch
docyard	docs site in, markdown out, no scraping by hand
fileyard	messy folders in, organized library out
proofyard	every claim ships with its receipt
