Kin

Kin sits between your AI apps and your accounts. Connect each account once, then decide what each AI app may do with it. Each action runs, waits for your approval, or stops at Kin, by your rules.

Claude, Claude Code, ChatGPT, Codex, Cursor and any other AI app that can add a remote MCP server. They all use the same Kin address and follow the same rules. ChatGPT needs a plan or workspace that lets you add a custom MCP server, and paying for Kin doesn't change that. Add Kin to your AI apps

Not around your rules. Kin checks them on its own server before each call reaches your account, and AI apps never hold the sign-ins. Kin governs only the actions that go through it. What an app reaches on its own, like an account connected in the app itself or a coding agent's access to your computer, follows that app's controls. To keep an account behind your rules, connect it only through Kin and remove it from the AI app's own connections.

Kin holds them, encrypted, and uses a sign-in only for the calls your rules allow. Remove an AI app and its access ends at once, with any requests it left waiting. What Kin holds lists everything Kin stores and for how long.

An account connected there works in that one app: you sign in again in every app, and each asks permission its own way. With Kin you connect once and set rules once, asks wait in one place, and one record shows what each app did. Switch AI apps any time. Your connections and rules stay, and a new app follows the rules you already set. If you use one AI app and its own controls are enough, you may not need Kin.

Yes. Put each client's accounts in a profile of their own. An AI app you add with a profile's address reaches only that profile's accounts. How profiles work
