The Actor is free to use, and you only pay for the Apify platform usage, which gets cheaper the higher subscription plan you have.

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases. In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours, and optionally produces a well-defined JSON output, datasets with results, or files in key-value store. In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server. Actors are written with capital "A". ## How to integrate an Actor? If asked about integration, you help developers integrate Actors into their projects. You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready. The best way to integrate Actors is as follows. In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md): ```bash npm install apify-client ``` In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md): ```bash pip install apify-client ``` In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md): ````bash # MacOS / Linux curl -fsSL https://apify.com/install-cli.sh | bash # Windows irm https://apify.com/install-cli.ps1 | iex ```bash In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md). If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md). For usage examples, see the [API](#api) section below. For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt). # README ## Tech Stack Detector MCP Server - Shopify, WordPress, SaaS ![Tech Stack Detector MCP Server - Shopify, WordPress, SaaS](https://ai-sales-personalizer.vercel.app/og/mcp-techstack-detective-mcp.png) **Give your AI agent 4 technographic tools: detect Shopify apps, WordPress plugins, DNS + email + SaaS footprint, and estimate SaaS spend. The foundation of competitive intelligence and vendor research.** Runs in Apify Standby mode (warm, responds in seconds). **Free to try right now** (in the 14-day price-notice window), then $0.10 per tool call. ### Who uses this - **Agencies** qualifying which sites run Shopify or WordPress before pitching app, theme, or migration work. - **Sales teams** prioritizing accounts by the exact SaaS a prospect already pays for. - **Competitive-intel & investors** fingerprinting a target's stack and vendor spend during diligence. - **AI agents** that need a site's technographic profile to personalize outreach. ### Connect in 30 seconds The server speaks **Streamable HTTP** at `/mcp`. Add this to your MCP client config: ```json { "mcpServers": { "techstack-detective": { "url": "https://fetchcraft--techstack-detective-mcp.apify.actor/mcp?token=YOUR_APIFY_TOKEN" } } } ```` Works in **Claude Desktop, Cursor, Cline, Windsurf, VS Code**, and any Streamable-HTTP MCP client. **Get your token:** sign in at apify.com, then Settings, then Integrations, then copy your **Personal API token**. Paste it in place of `YOUR_APIFY_TOKEN`. The first call wakes the standby server (about 5 seconds); after that, calls are instant. **Test it works** (replace the token): ```bash curl -s -X POST "https://fetchcraft--techstack-detective-mcp.apify.actor/mcp?token=YOUR_APIFY_TOKEN" \ -H "Content-Type: application/json" -H "Accept: application/json, text/event-stream" \ -d '{"jsonrpc":"2.0","id":1,"method":"tools/list","params":{}}' ``` ### What you get A representative result (clean structured JSON): ```json { "domain": "stripe.com", "mx_provider": "Google Workspace", "dmarc_policy": "reject", "cdn_provider": "Cloudflare", "saas_signals": ["AWS SES", "Atlassian", "SendGrid"] } ``` ### Tools | Tool | What it does | |---|---| | `detect_shopify_stack` | Shopify + 25+ app fingerprints (Klaviyo, Recharge, Yotpo) | | `detect_wordpress_stack` | WordPress + 30+ plugins (Elementor, Yoast, Rank Math) | | `dns_email_footprint` | MX, SPF, DMARC, CDN, hosting + 25 SaaS signals from DNS | | `scan_saas_spend` | 60+ SaaS tools on a site + estimated monthly spend | Each tool runs a maintained fetchcraft Apify Actor under the hood and returns clean structured JSON. No LLM key, no scraping infrastructure to manage. ### Example agent prompts - "What apps is gymshark.com running?" -> `detect_shopify_stack` - "What email vendor and SaaS does stripe.com use?" -> `dns_email_footprint` - "Estimate the SaaS spend of notion.so." -> `scan_saas_spend` ### Why pay-per-call beats a subscription - **No subscription, no seats, no minimums.** You pay $0.10 per call, only for what you actually use. Comparable tools in this space usually lock you into a monthly plan whether you run it or not. - **No LLM key and no scraping infrastructure to manage.** Connect your Apify token and the maintained Actors do the work, returning clean structured JSON. - **Built for AI agents.** Drop-in MCP server over Streamable HTTP for Claude Desktop, Cursor, Cline, Windsurf, and VS Code. - **$5/month in free Apify platform credits** on every account, that is 50 free calls every month, indefinitely. ### Pricing - **Free right now.** Every tool call is free during the 14-day price-notice window. - After that: **$0.10 per tool call**, flat. No subscription, no seat licenses, no minimum. - Every Apify account includes **$5/month in free platform credits** (= 50 free tool calls every month). ### FAQ **Which MCP clients work?** Any client supporting Streamable HTTP: Claude Desktop, Cursor, Cline, Windsurf, VS Code, and others. **Do I need an LLM key?** No. Connect your Apify token and go. **Is the first call slow?** Only the very first one, while the standby server wakes (about 5 seconds). Subsequent calls are instant. **Can I get the full fetchcraft suite?** Yes, 28 scrapers plus 6 MCP servers under the `fetchcraft` publisher.
