ChatGPT + Cuiar

ChatGPT runs the errand. You see every click.

  • Remote MCP with OAuth
  • ChatGPT asks before each write
  • No Cuiar credits for ChatGPT's steps
Set it up Get Cuiar

You already ask ChatGPT what to buy and where to book. With Cuiar as a plugin, ChatGPT can also open the shop, read your member price and fill in the form.

The work happens in real tabs on your computer, in the workspace you pick. ChatGPT asks you before each click or typed field. Sign-ins come from the Cuiar vault, so ChatGPT never sees a password.

A ChatGPT chat. The user types @ and picks the Cuiar plugin, then asks for a headphone price check. ChatGPT asks to confirm a click in Cuiar, the user confirms, and a table of three shop prices comes back.

Setup

Add Cuiar as a custom MCP plugin.

Do this one time, in ChatGPT on the web. The Cuiar app must be open and signed in on your computer when ChatGPT uses it.

    Open Plugins

    Go to chatgpt.com/plugins. Click the plus button, then Add custom MCP server.

  2. 2

    Enter the server

    Name it Cuiar. Under Connection, paste the server URL. Set Authentication to OAuth.

    Read the risk warning. Click I understand and want to continue, then Create as a plugin.

  4. 4

    Install and sign in

    Install the plugin from your personal plugins. ChatGPT opens cuiar.com. Sign in and allow the access.

  5. 5

    Mention it in a chat

    Type @ and pick Cuiar, then write the errand.

    @Cuiar In my Shopping workspace, find the Sony WH-1000XM6 on the three shops where I have an account. List the price with shipping and any member discount.

Route

ChatGPT reaches Cuiar over the remote server.

ChatGPT connects only to public remote MCP servers. Cuiar's server is public and signs in with OAuth. ChatGPT cannot start programs or run commands on your computer, so the other routes do not apply.

Good to know

Plans
OpenAI's help center lists full custom MCP support for Business, Enterprise and Edu, and read and fetch only for Pro. Cuiar's click and type tools write. Check your plan before you set it up.
Your computer
ChatGPT works from OpenAI's cloud. The tabs open in the Cuiar app on your computer, so the app must be open and signed in.
Credits
ChatGPT's own tool calls use no Cuiar credits. run_task gives the whole errand to the Cuiar agent and uses credits.
