Getting started

Ouroboros Apps makes AI plugins for ChatGPT, Claude, Grok, and Cursor. A plugin here is a small server your assistant can call. It holds facts you saved. The assistant reads those facts before it answers, instead of filling the gap from the chat.

What you connect

Each plugin has one address that ends in /mcp. You paste that address into Claude, Cursor, Grok, or ChatGPT developer mode. The client asks the server which tools exist. That list is public. Using a tool is not.

There are ten plugins: Claim, Continuity, Deposit, Desk, Invoice, Milestone, Papers, Patent, Rank, and Scope. They all connect the same way.

In ChatGPT, Continuity is in the app directory and the other nine are still in review. Until they're listed, paste the address yourself in developer mode, or use Claude, Cursor, or Grok.

How sign-in works

1. You add the connector and choose sign-in. Leave the client id and secret empty. The server registers the client for you.
2. A browser window opens. You sign in there. Don't paste a password or a token into the chat or into request headers.
3. After that, the assistant can call tools on your account. If it tries before you sign in, the server says no.

You approve what gets saved. The plugin does not watch your other chats.

Pick your app: Claude, Cursor, Grok, ChatGPT. Plugin pages are in the sidebar.
