# Dedupe Bookmarks — MCP tool `findutils:dedupe_bookmarks`

Remove duplicate links from a Netscape bookmarks.html export (Chrome, Firefox, Edge, Safari) and return a clean bookmarks.html plus a CSV of the duplicates. Two bookmarks are duplicates when their addresses match after folding letter case in the host, default ports and a trailing slash, and, by default, after dropping utm_* / fbclid / gclid tracking parameters and the #fragment. The first copy is kept with its title, date and folder; the duplicates CSV lists every folder a copy sat in. Other query parameters are never touched, non-web addresses compare verbatim, and no link is fetched.
