Connecting Liberator to ChatGPT

Use ChatGPT’s MCP connector with OAuth to query CloudQuant Data Liberator from a ChatGPT workspace. Each user authenticates with their own Liberator credentials, so data access follows individual entitlements rather than a shared API key.

​
Prerequisites

  • Access through app.cloudquant.ai — ChatGPT MCP setup for Liberator is done from that CloudQuant environment.
  • A ChatGPT Pro or Plus account — the MCP connector is only available on paid tiers.
  • Developer tool access enabled in ChatGPT (required before you can create custom Apps). Enable it under Settings.
  • A CloudQuant Data Liberator account with valid username and password.
  • The Liberator MCP Endpoint URL from the Liberator UI (for example, https://api.cloudquant.ai/mcp).
OAuth is the recommended authentication method. Each user who connects through the ChatGPT app authenticates with their own Liberator credentials, so entitlements stay per-user.

​
Setup steps

1

Open ChatGPT Settings

In ChatGPT, click your workspace or profile name in the lower-left corner, then select Settings.
2

Create an App under Advanced settings

In Settings, open the Advanced section, click Apps, then click Create App.
3

Fill in the app details

In the New App dialog, set:Example MCP Endpoint URL:
Copy the exact URL from your Liberator UI if your environment differs.
4

Set authentication to OAuth

Under Authentication, select OAuth. This is the recommended method for Liberator and keeps access tied to each user’s credentials.
5

Accept the custom MCP warning and create

ChatGPT shows a warning that custom MCP servers introduce risk. Check I understand and want to continue, then click Create. The Create button stays inactive until you acknowledge the warning.
6

Authenticate and grant access

ChatGPT starts the OAuth flow and shows a Grant Access to ChatGPT screen. Approve access for:
  • User profile
  • openid
  • User roles
  • Email address
  • groups
Click Yes to grant access so ChatGPT can authenticate to the Liberator MCP server on your behalf.
Once access is granted, the CloudQuant Liberator MCP connector is ready to use in your ChatGPT workspace.

​
Using the connector

After the app is created, Liberator MCP tools are available in ChatGPT conversations:
Because OAuth is used, each user who interacts with the connector is prompted to authenticate with their own CloudQuant credentials. Individual data access and entitlements apply — no shared API keys are required.
