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.
