  "markdown": "# MCP Factory: pay-per-use MCP tools for AI agents\n\n**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.\n\n## The tools\n\n### 🔍 Tech Stack Detector\n\nFind 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**.\n\n- **MCP server URL:** `https://mcp.apify.com?tools=apifmcpfactory/tech-stack-detector`\n- **Apify Store:** [apify.com/apifmcpfactory/tech-stack-detector](https://apify.com/apifmcpfactory/tech-stack-detector)\n- **Try an example task:** [run it with sample input](https://apify.com/apifmcpfactory/tech-stack-detector/input)\n- **Details:** [tech-stack-detector/](tech-stack-detector/)\n\n### 🧾 EU VAT Validator\n\nValidate 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**.\n\n- **MCP server URL:** `https://mcp.apify.com?tools=apifmcpfactory/eu-vat-validator`\n- **Apify Store:** [apify.com/apifmcpfactory/eu-vat-validator](https://apify.com/apifmcpfactory/eu-vat-validator)\n- **Try an example task:** [run it with sample input](https://apify.com/apifmcpfactory/eu-vat-validator/input)\n- **Details:** [eu-vat-validator/](eu-vat-validator/)\n\n### 🤖 llms.txt Checker\n\nA 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.**\n\n- **MCP server URL:** `https://mcp.apify.com?tools=apifmcpfactory/llms-txt-checker`\n- **Apify Store:** [apify.com/apifmcpfactory/llms-txt-checker](https://apify.com/apifmcpfactory/llms-txt-checker)\n- **Try an example task:** [run it with sample input](https://apify.com/apifmcpfactory/llms-txt-checker/input)\n- **Details:** [llms-txt-checker/](llms-txt-checker/)\n\n## Connect all three tools at once\n\nOne MCP server URL exposes any combination of tools. To give your agent the full MCP Factory toolkit:\n\n```\nhttps://mcp.apify.com?tools=apifmcpfactory/tech-stack-detector,apifmcpfactory/eu-vat-validator,apifmcpfactory/llms-txt-checker\n```\n\n**Claude Desktop** (`claude_desktop_config.json`):\n\n```json\n{\n    \"mcpServers\": {\n        \"mcp-factory\": {\n            \"command\": \"npx\",\n            \"args\": [\n                \"mcp-remote\",\n                \"https://mcp.apify.com?tools=apifmcpfactory/tech-stack-detector,apifmcpfactory/eu-vat-validator,apifmcpfactory/llms-txt-checker\",\n                \"--header\",\n                \"Authorization: Bearer YOUR_APIFY_TOKEN\"\n            ]\n        }\n    }\n}\n```\n\n**Cursor** (`.cursor/mcp.json`):\n\n```json\n{\n    \"mcpServers\": {\n        \"mcp-factory\": {\n            \"url\": \"https://mcp.apify.com?tools=apifmcpfactory/tech-stack-detector,apifmcpfactory/eu-vat-validator,apifmcpfactory/llms-txt-checker\",\n            \"headers\": {\n                \"Authorization\": \"Bearer YOUR_APIFY_TOKEN\"\n            }\n        }\n    }\n}\n```\n\nReplace `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.\n\n## How pricing works\n\nEvery 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).\n\n## About\n\nMCP 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.\n",
