Douze turns a website you're already signed in to into MCP tools your assistant can call. Hit "Watch this site", do the task once, and Douze infers tools from that tab's API traffic. You review every candidate - grouped as reads, writes and destructive - and approve only what to expose. Calls then run inside your own browser session: no API keys, no scraping, no re-auth. Passwords, cookies and tokens are redacted before capture. Works with ChatGPT, Claude or a local MCP client. Open source.
