Website intelligence for your AI assistant

Connect Stackcrawler to Claude, Codex, and ChatGPT to scan websites, discover technology stacks, and research technology adoption.

Connect with Model Context Protocol

MCP gives your assistant access to Stackcrawler’s website technology data. Scan a public website, find sites using a technology or theme, and explore newly detected technologies without writing API requests.

Available tools

scan_website

Identify a public website’s frameworks, ecommerce platform, analytics, hosting, and CMS. Optionally include public contacts and social profiles.

find_websites_by_technology

Find indexed websites using a technology slug, with language, domain, keyword, and Lighthouse score filters.

find_websites_by_theme

Find indexed websites using a theme slug, with the same discovery filters.

get_technology_migrations

Explore websites where a technology was newly detected. Filter by technology and paginate through results.

Tools are read-only. Discovery results are limited to 20 websites per call, with pagination for further results.

Authentication and usage

Use a Stackcrawler API key with Claude Code or Codex. Browser connections use OAuth sign-in when enabled on the hosted service. MCP calls follow the same subscription limits, rate limits, and usage accounting as the REST API.
