History-Sync

History Sync turns Chrome's browsing history into something your AI agents can actually use. Install the extension, sign in once with Google, and any page you dwell on for 10+ seconds gets captured to your own server. Then point Claude, Cursor, Claude Desktop, or any other MCP-capable client at the server and ask what you've been reading. WHAT GETS CAPTURED · URL, title, basic page metadata (description, OpenGraph tags) · How long you dwelled on the page · The visit timestamp WHAT NEVER GETS CAPTURED · Incognito browsing — the extension declares incognito: not_allowed · chrome:// pages, extension internals, privileged URLs · Form contents, passwords, cookies, page-body text beyond title/metadata · Anything from sites you've added to your disallow list WHAT YOU CONTROL · One-click pause from the extension popup · "Block this site" to stop capture on the active tab · Wildcard disallow patterns (e.g. *.bank.com) — applied retroactively AND going forward, so prior matching entries are deleted from the server · Revoke any MCP client from the web dashboard — token stops working on the next call HOW IT WORKS The extension flushes captured pages to history-sync.vercel.app every ~60 seconds. The server exposes them via MCP at /api/mcp/mcp with OAuth scoped per-client. Source is open; see GitHub link.
