Screaming Frog SEO Spider MCP Server An MCP (Model Context Protocol) server that gives Claude (or any MCP-compatible client) programmatic access to Screaming Frog SEO Spider — crawl websites, export crawl data, and manage your crawl storage, all from your AI assistant. Prerequisites Screaming Frog SEO Spider installed on your machine (tested with v23.x, should work with v16+). Download from: https://www.screamingfrog.co.uk/seo-spider/ A valid Screaming Frog license. The free version has a 500-URL crawl limit. Most MCP features (headless CLI, saving/loading crawls, exports) require a paid license. Python 3.10+ Important: How the Workflow Works Screaming Frog uses an internal database that can only be accessed by one process at a time. This means: You must close the Screaming Frog GUI before the MCP server can access crawl data. The typical workflow is: Run your crawl — either through the SF GUI (with all your custom settings, filters, etc.) or via the MCP tool. Close the Screaming Frog GUI — the GUI locks the crawl database. The MCP server's headless CLI cannot read or export data while the GUI is running.
