# MCP Factory: pay-per-use MCP tools for AI agents
**MCP Factory** builds small, reliable, pay-per-use tools that AI agents can call over the [Model Context Protocol (MCP)](https://modelcontextprotocol.io). Each tool runs as an [Apify Actor](https://apify.com/apifmcpfactory) and is exposed through Apify's hosted MCP server — no installation, no infrastructure, no subscription. Your agent calls the tool directly; usage bills through your Apify account at flat, transparent per-result prices.
## The tools
### 🔍 Tech Stack Detector
Find out what any website is built with. Scans a list of URLs and identifies the technologies behind each site — CMS, ecommerce platform, web frameworks, analytics, CDN, web server, and more — using the open-source webappanalyzer fingerprint dataset (7,500+ technologies across 109 categories). A fast, affordable Wappalyzer / BuiltWith alternative at roughly **$5 per 1,000 sites**.

- **Apify Store:** [apify.com/apifmcpfactory/tech-stack-detector](https://apify.com/apifmcpfactory/tech-stack-detector)
- **Try an example task:** [run it with sample input](https://apify.com/apifmcpfactory/tech-stack-detector/input)
- **Details:** [tech-stack-detector/](tech-stack-detector/)
### 🧾 EU VAT Validator
Validate EU VAT numbers in bulk against **VIES**, the European Commission's official VAT validation service — and get the official **consultation number** on every check as audit evidence for tax inspections. Bulk-safe with automatic retries, tolerant of messy input formats, **$5 per 1,000 validations flat**.

### 🤖 llms.txt Checker
A complete **AI readiness audit** for any website in one pass: checks **llms.txt**, **llms-full.txt**, **robots.txt AI-crawler policy** (GPTBot, ClaudeBot, PerplexityBot, Google-Extended, CCBot, Bytespider), and **sitemap.xml**, then returns a **0–100 AI readiness score** with a plain-English list of exactly what to fix. **~$5 per 1,000 sites.**

## Connect all three tools at once
One MCP server URL exposes any combination of tools. To give your agent the full MCP Factory toolkit:
```
https://mcp.apify.com?tools=apifmcpfactory/tech-stack-detector,apifmcpfactory/eu-vat-validator,apifmcpfactory/llms-txt-checker
```
**Claude Desktop** (`claude_desktop_config.json`):
```json
{
"mcpServers": {
"mcp-factory": {
"command": "npx",
"args": [
"mcp-remote",
"https://mcp.apify.com?tools=apifmcpfactory/tech-stack-detector,apifmcpfactory/eu-vat-validator,apifmcpfactory/llms-txt-checker",
"--header",
"Authorization: Bearer YOUR_APIFY_TOKEN"
]
}
}
}
```
**Cursor** (`.cursor/mcp.json`):
```json
{
"mcpServers": {
"mcp-factory": {
"url": "https://mcp.apify.com?tools=apifmcpfactory/tech-stack-detector,apifmcpfactory/eu-vat-validator,apifmcpfactory/llms-txt-checker",
"headers": {
"Authorization": "Bearer YOUR_APIFY_TOKEN"
}
}
}
}
```
Replace `YOUR_APIFY_TOKEN` with your API token from [Apify Console](https://console.apify.com/settings/integrations). New Apify accounts include free monthly usage credit, so you can try every tool before paying anything.
## How pricing works
Every tool is **pay-per-event**: a small flat fee per run plus a flat fee per result. No subscriptions, no tiers, no minimums. Usage is billed through the Apify account whose token your agent uses — you can see every run, result, and charge in [Apify Console](https://console.apify.com).
## About
MCP Factory publishes on the Apify platform as [apifmcpfactory](https://apify.com/apifmcpfactory). Each tool is designed around the same principles: one clear job, bulk-safe execution (one output row per input, always), honest pricing, and output an AI agent can use without post-processing.
