Screaming Frog SEO Spider MCP Server (headless) runs on your own machine — the client starts it, so there is no endpoint to ping. 886 installs a week from pypi. Last commit 31 Aug 2026.
Headless Screaming Frog SEO Spider via its CLI: run crawls, export and filter data, no GUI needed.
Today is the operative word: we check Screaming Frog SEO Spider MCP Server (headless) every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.
