概览

AI 生成的概览

本地 MCP 服务器，监控竞品商店与 SaaS 站点，仅返回自上次运行以来的价格、库存、套餐和更新日志变化。

可以做什么
  • 监控竞品站点：提供域名或网址，只返回与相同 state_key 上次运行相比发生变化的内容。
  • 读取商店数据：Shopify 商店通过其公开商品 feed 读取，WooCommerce 商店通过其公开 Store API 读取。
  • 跟踪价格与套餐：覆盖竞品商店和 SaaS 站点的价格、库存、套餐及更新日志变化。
适用场景
适合让助手持续关注竞品价格、库存、套餐或更新日志，并只呈现差异而非整页内容，例如定期竞品调研或调价检查。
运行要求
以本地 stdio 进程运行，从 npm 包安装，需要 Node.js 运行时。需要 Apify API 令牌，通过环境变量 APIFY_TOKEN 提供。需要访问被监控站点和 Apify 的网络连接。仅限桌面端。
安装前请注意
需要 Apify API 令牌（APIFY_TOKEN），该凭据可能关联付费 Apify 账户并产生用量费用。它会向第三方站点和 Apify 发送请求，因此所监控的域名会与这些服务共享。它按 state_key 在多次运行间保存状态，结果依赖复用同一 key。

安装

在 SourceWeft 中

  1. 打开 控制台中的 Mcp Competitor Price Stock Changelog Monitor，将其添加到工作区。
  2. 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。

[Competitor Price Stock Changelog Monitor MCP server]

An MCP server for the Mamba Labs Competitor Price, Stock, and Changelog Monitor actor on Apify. Give it competitor sites. Each run compares every site with the state saved by the last run and returns only what changed.

What's Inside

What it does

  • Stores: Shopify stores through their public product feed and WooCommerce stores through their public Store API. Changes: price_change, compare_at_price_change, out_of_stock, back_in_stock, new_product, removed_product, each with the product, variant, old and new value, and a link.
  • SaaS sites: the pricing page and changelog the site links to. Changes: plan_added, plan_removed, plan_price_change, pricing_page_change, and changelog_entry.
  • One row per site per run: site_baseline on the first check under a state_key, then site_check with changes_found for a site that changed, or a free no_change row when nothing moved.

Unreadable sites come back free with a row_status saying so.

All of the work runs on Apify. This package is a thin client that starts the actor run, waits for it, and hands back the dataset rows.

Quick start

You need Node.js 18 or newer and an Apify account with an API token.

Add this to your Claude Desktop config (claude_desktop_config.json), Cursor, or any MCP client:

json
{  "mcpServers": {    "mamba-competitor-price-stock-changelog-monitor": {      "command": "npx",      "args": [        "-y",        "@mambalabsdev/mcp-competitor-price-stock-changelog-monitor"      ],      "env": {        "APIFY_TOKEN": "your-apify-token"      }    }  }}

Restart the client. The monitor_competitor_changes tool appears.

Prerequisites

Example prompts

  • "Watch deathwishcoffee.com and allbirds.com for price cuts of 10 percent or more and tell me what changed since last week."
  • "Did Notion or Linear change their pricing plans or ship anything new this week?"
  • "Which products went out of stock on gymshark.com since yesterday?"

Tool

monitor_competitor_changes. One tool. Example arguments:

json
{  "sites": [    "deathwishcoffee.com",    "linear.app"  ],  "state_key": "competitors-weekly",  "min_price_change_pct": "5"}

Inputs

Every buyer facing input of the actor, unchanged. Omitted inputs take the actor's own defaults. Numbers and booleans are sent as strings.

InputTypeDescription
sitesarrayCompetitor sites to watch, one per line: a domain (deathwishcoffee.com, linear.app) or a URL. A URL with a path is read as that page: a pricing page, a changelog page, or a product page. Up to 200 sites per run
site_typestringauto (default) reads the public Shopify product feed or the WooCommerce Store API when the site has one, and otherwise reads the pricing and changelog pages it links to
watcharrayAny of: prices, stock, products, plans, changelog. prices covers price and compare at price per variant; stock covers in stock and out of stock; products covers new and removed products; plans covers plan names and prices on a pricing page; changelog covers new changelog entries. Empty means all five
product_urlsarrayProduct pages on a store that is not Shopify or WooCommerce. Each page is read for its schema.org Product price and availability
pricing_urlsarrayPricing pages to read, when the site does not link to its pricing page from the homepage
changelog_urlsarrayChangelog or release notes pages to read, when the site does not link to one from the homepage. An RSS or Atom feed the page declares is read first
max_productsstringProducts read from a store catalog per run, up to 5000. A store with more products than this is compared on the products read, and removed products are not reported for it. Default 250
min_price_change_pctstringReport a price change only when it is at least this many percent. 0 reports every change. Default 0
max_changes_per_sitestringChange rows returned per site per run, up to 1000. The rest are counted in changes_found. Default 200
include_snapshotstringtrue to also return one snapshot row per product variant, plan, and changelog entry on the first check of a site. Each snapshot row is billed as a snapshot row. Default false
state_keystringNames the saved state, so separate schedules keep separate baselines. Runs with the same state key and site compare against each other
reset_statestringtrue to ignore the saved state and record a new baseline for every site. Default false
max_charge_usdstringOptional. The run stops before it would charge more than this
proxy_modestringauto (default) sends requests directly and moves a host to the Apify proxy default pool only when that host refuses. A reliability setting: proxy use adds nothing to your price

Pricing

Pay per event on Apify, billed to your Apify account. Prices in USD.

A site where nothing moved returns a free no_change row, and sites that cannot be read are free.

Your keys

The actor needs no key. It reads public product feeds and public pages and holds no key of any kind. Proxy traffic adds nothing to your price: Mamba Labs pays the platform costs of the run. proxy_mode is a reliability setting.

monitor_competitor_changes

Monitor competitor prices, stock, and changelogs

Watch competitor stores and SaaS sites and return only what changed since the last run with the same state_key. Give sites as domains or URLs (for example deathwishcoffee.com, linear.app). Shopify stores are read from their public product feed and WooCommerce stores from their public Store API, so you get price, compare at price, and stock changes per variant, plus new and removed products. SaaS sites are read from the pricing and changelog pages they link to, so you get plans added, removed, or repriced, and new changelog entries. Every site gets one row per run (site_baseline on the first check, then site_check with changes_found), plus one row per change with old and new values. Unreadable sites come back free with a row_status saying so. A run that does not succeed is returned as an error with its run ID. Read-only; requires an APIFY_TOKEN; Apify charges per change row and per site check that is a first check or finds a change; an unchanged site is free.
