Your inventory.
Now in conversation.

Before you start

• An existing, active Rattib account with setup completed and Google linked. Free, Pro, and Pro Plus accounts can connect.
• ChatGPT on the web with permission to add custom MCP connections. Availability depends on your ChatGPT account and workspace settings.
• A few minutes to sign in and choose which inventory ChatGPT can read. This guide does not sign you in or read your inventory.

This is an early-access custom connection, not a listing in ChatGPT’s public directory. The connection addresses still include staging; use the exact settings below.

Link Google in Rattib

1. Open Rattib and stay signed in to the account that contains your inventory.
2. Open Profile → Sign-in methods, then link Google if it is not already linked.
3. Use that same Google account when connecting Rattib in ChatGPT.

Your ChatGPT login email can be different. What matters is the Google account you choose during the Rattib connection sign-in.

Add the connection in ChatGPT

Open ChatGPT Plugins (opens in a new tab), select +, then Add custom MCP server. Suggested name: Rattib — inventory.

Under Connection, use the following server URL and choose OAuth for authentication.

Open Advanced OAuth settings and choose User-Defined OAuth Client.

Client Secret

Leave empty

Token endpoint auth method

none

Scopes

Select profile:read and inventory:read

Optional editing scope

Also select inventory:edit only if you want ChatGPT to edit existing inventory

Base scopes

Leave empty

OIDC enabled

Off

Review ChatGPT’s custom-connection warning. If you agree, accept it and select Create as a plugin. Install the resulting plugin if ChatGPT asks you to.

Sign in and choose your access

1. Continue with the Google account linked in step 1. The Rattib sign-in opens at auth-staging.rattib.com.
2. Check that the Rattib account shown is yours.
3. Select the current Spaces you want to share. Include current Outside Items if you want ChatGPT to find those too. Nothing is selected automatically.
4. Review and approve the requested read-only or editing permission, then return to ChatGPT. Editing requires its own explicit consent.

New Spaces need new permission. Choosing all current Spaces does not grant access to future Spaces. New items inside a selected Space can be read, subject to your current permissions. Outside access covers the items selected at consent time, not every future Outside Item.

To include additional Spaces or Outside Items later, disconnect the old grant, then reconnect and choose your updated scope.

Start with a question

In a ChatGPT conversation, type @ and select your installed Rattib plugin. Ask it to use Rattib, for example:

• “Use Rattib to find my chargers in the bedroom. Tell me their Space names.”
• “What could I take from my inventory for a fishing trip? Check all available pages.”
• “List the items in my travel Space, including quantities and descriptions.”

Large inventories arrive in pages. A first response may be only a partial list; ask ChatGPT to continue until there are no more pages. There is no total 25- or 200-item connection limit, but only the inventory you authorized is available.

ChatGPT can read item details, Space names, locations, quantities, categories, notes, linked-item references, and available current AI descriptions. AI descriptions are supporting context, not verified facts. Check important answers against Rattib.

Optional edits to existing inventory

With the editing scope, ask ChatGPT to update an existing Item’s name, description, quantity, category, notes, or saved AI description; edit an existing Space’s name, notes, status, or location; or move a whole Item to an existing Space. Categories, statuses, locations, and destination Spaces must already exist. Source and destination must be in your selected access and you must be an Owner, not a Guest.

Review the exact records and changes before approving a tool action. Changes affect the same inventory used by the Rattib app and other Owners. Partial-quantity moves, moving to Outside, adding, deleting, duplicating, combining, photo changes, sharing changes, and Checklist edits are not supported through this connection.

Already connected? Your read-only connection remains read-only. Refresh the tool list and reconnect with inventory:edit selected, then approve the new editing consent. If ChatGPT cannot change the connection’s scopes, create a separate connection with the settings above. Never share a client secret.

You stay in control

The connection can read your profile and authorized inventory. Only a separately approved editing connection can change existing Owner-editable records. It cannot create or delete Items or Spaces, or change sharing. Photos and Checklists are not provided through this connection. Your existing sharing permissions still apply.

Information retrieved through the connection is sent to ChatGPT for your conversation. Only connect the Spaces and Outside Items you are comfortable sharing. This website stores no connection credentials.

You can stay connected between conversations, but may occasionally need to sign in again. To stop future access, open Manage Rattib connections (opens in a new tab), sign in with the same Google account, and choose Disconnect. You can also remove the plugin in ChatGPT.

Disconnecting does not delete information already shared in a ChatGPT conversation, or undo edits already saved. Manage that content separately in ChatGPT and review saved changes in Rattib. Read the Rattib Privacy Policy before connecting.
