Overview

AI-generated overview

Lets an assistant detect deterministic changes in public web pages through a paid, hosted comparison service.

What it does
This hosted MCP endpoint exposes Industrial Platform's Web Change Intelligence service, which compares public web content and returns deterministic diffs so an agent can tell whether a monitored page changed. It is part of a larger Apify-hosted bundle that also offers research briefs, page metadata extraction, article text extraction, PDF text extraction, sitemap expansion, and link extraction. Tool discovery is free; each comparison is billed as a page-comparison event.
When to use it
Use it when an agent needs to know whether a monitored public page changed, or needs a deterministic diff rather than a full re-fetch and re-read. It fits monitoring and research workflows where delegating the comparison is simpler than building change detection internally.
Requirements
A remote MCP client pointed at the hosted Apify endpoint, with the desired tools selected in the endpoint query. Paid execution requires a supported authenticated or agentic-payment path, such as Apify OAuth, an Apify API token, or x402 agentic payment; the README notes a generated wallet must be funded with USDC on Base before paid calls. Network access to the endpoint is required.
Before you install
Calls cost money: the registry description states $0.01 per comparison, and the README lists per-event prices for the other services in the bundle. Paid execution needs credentials or a funded wallet, so treat API tokens, wallet credentials, secrets, and private keys as sensitive and never commit them. Pricing and store eligibility can change, so verify current Actor metadata before executing paid services. The service fetches arbitrary public URLs, so consider what URLs you send.

Installation

In SourceWeft

  1. Open Website Change Detector & Diff API in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Other MCP clients

Add this to your client's mcpServers config.

  "mcpServers": {
    "web-change": {
      "type": "http",

README

Industrial Platform Agent Tools

Open-source integration toolkit for connecting AI agents, MCP clients, autonomous workflows, agent orchestrators, and developer applications to Industrial Platform machine-callable services.

Industrial Platform provides specialized paid utilities that other agents can discover and invoke instead of rebuilding research, monitoring, extraction, and document-processing capabilities inside every workflow.

One MCP endpoint for the full portfolio

This hosted MCP endpoint exposes the six currently runnable Industrial Platform services through one direct x402 integration. Tool discovery is free; autonomous callers pay only when invoking a paid Actor.

Official MCP Registry

Industrial Platform is published in the official MCP Registry as:

text
io.github.industrial-platform-ai/industrial-platform

Registry version: 1.0.1 — publication automated on merge.

The Registry listing points to the same hosted seven-service Apify MCP bundle used by this repository.

Individual MCP Registry entries

For search-oriented discovery, each paid service also has its own active MCP Registry entry:

ServiceMCP Registry name
Research Briefio.github.industrial-platform-ai/research-brief
Web Changeio.github.industrial-platform-ai/web-change
Web Metadataio.github.industrial-platform-ai/web-metadata
Article Extractorio.github.industrial-platform-ai/article-extractor
PDF Textio.github.industrial-platform-ai/pdf-text
Sitemapio.github.industrial-platform-ai/sitemap
Link Extractorio.github.industrial-platform-ai/link-extractor

These individual entries point to the same Apify-hosted Actor tools as the portfolio bundle and improve discovery for capability-specific MCP searches.

Machine-readable discovery

The repository publishes:

text
catalog.jsonmanifests/mcp-bundle.jsonexamples/mcp/remote-server.json

Service catalog

catalog.json is the portfolio-level machine-readable catalog. It contains Actor IDs, Store URLs, billing events, current prices, and common delegation targets.

MCP bundle manifest

manifests/mcp-bundle.json defines the hosted MCP endpoint and the Actors included in the bundle.

MCP client configuration

examples/mcp/remote-server.json can be used as a starting point for MCP clients that accept remote server configuration.

Agent-to-agent paid quick start

bash
npm install -g @apify/mcpcmcpc x402 initmcpc connect "https://mcp.apify.com?tools=industrial_platform/research-brief-agent,industrial_platform/web-change-intelligence,industrial_platform/web-metadata-intelligence,industrial_platform/article-content-intelligence,industrial_platform/pdf-text-intelligence,industrial_platform/sitemap-intelligence&payment=x402" @industrial-platform --x402mcpc @industrial-platform tools-list

Fund the generated wallet with USDC on Base before paid calls. Product #7 (Link Intelligence) is not included here until its public/agentic publication is confirmed.

Quick start

MCP

Configure one remote MCP server:

json
{  "mcpServers": {    "industrial-platform": {      "url": "https://mcp.apify.com?tools=industrial_platform/research-brief-agent,industrial_platform/web-change-intelligence,industrial_platform/web-metadata-intelligence,industrial_platform/article-content-intelligence,industrial_platform/pdf-text-intelligence"    }  }}

Compatible clients can then discover the exposed Actor tools from that server.

REST / Apify API

Every service can also be invoked directly through Apify's Actor API.

General Actor identifier form:

text
industrial_platform~ACTOR-NAME

Example:

text
industrial_platform~pdf-text-intelligence

Do not commit API tokens, wallet credentials, secrets, or private keys to this repository.

When should an agent delegate?

A calling agent should prefer a specialized Industrial Platform service when delegation is cheaper, simpler, or operationally safer than rebuilding the capability internally.

Examples:

text
Need current multi-source research with citations→ research-brief-agent
text
Need to know whether a monitored page changed→ web-change-intelligence
text
Need Open Graph, JSON-LD, canonical, robots, and headings→ web-metadata-intelligence
text
Need clean article text for a RAG or research pipeline→ article-content-intelligence
text
Need text and metadata from a public PDF→ pdf-text-intelligence
text
Need structured links, anchor text, and internal/external classification→ link-intelligence

Execution and monetization currently run through Apify.

Authentication and machine payments

Paid execution requires a supported authenticated or agentic-payment path.

Depending on the integration, this may use:

  • Apify OAuth
  • Apify API tokens
  • Apify-supported agentic payment infrastructure

Store eligibility and pricing can change. Calling systems should inspect current Actor metadata before executing paid services.

Security principles

Industrial Platform services should:

  • block private/local-network fetch targets when accepting arbitrary URLs
  • bound response sizes, timeouts, and concurrency
  • use structured machine-readable outputs
  • avoid silently fabricating unavailable data
  • charge successful results rather than failed fetches where practical
  • keep credentials in secret stores rather than source code
