What is I built an MCP?
Bookmarks OS is a bookmark manager designed to replace your browser's native bookmarking system. It lets you save, organise, and retrieve bookmarks across multiple browsers and devices using folders, tags, and full-text search. The tool addresses a common frustration: browser bookmarks are difficult to search, share, and access consistently across different devices. Bookmarks OS centralises your saved links in one place with better organisation tools and cross-platform access. It's particularly useful for researchers, content curators, project managers, and anyone who saves dozens of links daily and needs to find them later without scrolling through chaotic folders.
