As an MCP server

{ "mcpServers": { "everthread": { "command": "npx", "args": ["-y", "everthread", "mcp"] } } }

Tools: check_site, explain_finding, list_findings. Works with Claude Code, Claude Desktop, Cursor, and anything else that speaks MCP.

What it does and doesn't do

It loads the home page the way a browser does and reads the certificate, security headers, scripts, forms, frames, redirects, a fixed handful of well-known files, and the page text. It never logs in, probes for hidden paths, or runs exploit tooling. Public results withhold the exact address of an exposed file; the site owner sees it after signing up. Only check sites you own or have permission to check.
