Techstack Detective

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:

{
  "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):

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):

{
  "domain": "stripe.com",
  "mx_provider": "Google Workspace",
  "dmarc_policy": "reject",
  "cdn_provider": "Cloudflare",
  "saas_signals": ["AWS SES", "Atlassian", "SendGrid"]
}

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.

• $5/month in free Apify platform credits on every account, that is 50 free calls every month, indefinitely.

Pricing

• After that: $0.10 per tool call, flat. No subscription, no seat licenses, no minimum.
