Connect Lose It! to your AI assistant
Get a private link that lets Claude, ChatGPT, or any MCP client log your food and weight in Lose It!
Your private link
Treat this link like a password. Anyone who has it can read and change your Lose It! diary. Paste it only into your AI client's settings, and don't post it anywhere. It expires in days.
Add it to your client
- Claude — Settings → Connectors → Add custom connector, and paste the link.
- ChatGPT — Settings → Connectors → add an MCP server, and paste the link.
- Claude Code / other MCP clients — add it as a streamable-HTTP MCP server.
No extra credentials to configure: the link authenticates by itself. Then try asking your assistant “what did I eat today?”
What happens to your password
- It is never saved on this server. It is used once, in memory, to confirm Lose It! accepts it — then it is gone. Nothing is written to any database or disk here, because there is no database.
- It is encrypted into your link. This is the part worth understanding: your link contains your credentials, encrypted with a key only this server holds. That is how it works without an account system. The server can open it while serving your request; anyone who sees the link cannot. This also means the link itself is as sensitive as your password.
- Your login token is never stored either. The token Lose It! returns is kept in memory only, so it can be reused for a few minutes instead of logging in on every request, and it disappears when the server restarts.
- It never appears in logs. Request logs would normally record the full URL, so the credential-carrying part is stripped out before anything is written. The password is never logged in any form.
- Nothing is shared with anyone. Your credentials go to Lose It! and nowhere else. This page loads no outside code, so no analytics or CDN sees you here.
- To revoke a link, change your Lose It! password. That invalidates every link ever issued for your account.
Lose It! has no official API and no “sign in with Lose It” button, so a password is unfortunately the only way in. This project is open source — you can read exactly what it does, or run your own copy.
