How to Connect ChatGPT to the Ezekia MCP (enabling the App in ChatGPT) : Ezekia

This article explains how ChatGPT Enterprise Owners or Admins can connect ChatGPT to Ezekia using Model Context Protocol (MCP) and make the Ezekia MCP connector app available for end users within their organisation. Once enabled, ChatGPT users can securely search, create, and update data in Ezekia using natural language - directly from within ChatGPT.

Important: ChatGPT vs Ezekia’s Built-in AI

Ezekia supports two completely separate AI integrations:

Ezekia Built-in AI/Sidekick

Uses the OpenAI API
Requires an OpenAI API key and credits
Configured inside Ezekia
Powers features such as Sidekick and summarisation within the platform

ChatGPT via MCP

Uses ChatGPT as an external AI tool
Does not use an OpenAI API key
Does not consume OpenAI API credits
Does not use an Ezekia API token
Is configured inside ChatGPT (not Ezekia)

Connecting ChatGPT via MCP is independent of enabling Sidekick and other AI features inside Ezekia.

Who This Guide Is For

This setup must be completed by a ChatGPT Enterprise plan Owner, or by an Admin where permitted by their ChatGPT role permissions.

Owners can publish connector apps for organisational use
Admins can create connector apps with availability depending on permissions
End users cannot enable MCP themselves
ChatGPT users log in (if required) and approve access to Ezekia via an OAuth pop-up authorisation prompt (see How Authentication Works below).

All connector apps are visible only within your organisation.

How Authentication Works

ChatGPT uses an OAuth authorisation flow to allow users to approve access to Ezekia the first time they use the Ezekia MCP connector app. When prompted, users may be asked to log in to Ezekia (if they are not already signed in) and then approve access. Once authorised, ChatGPT can interact with Ezekia on the user’s behalf, respecting their existing Ezekia permissions. End users do not generate, manage, or enter API tokens when using the Ezekia MCP app in ChatGPT.

Prerequisites

To use ChatGPT with Ezekia via MCP, you will need:

A ChatGPT Enterprise subscription
Owner or Admin access in ChatGPT
Access to Ezekia MCP by way of an Ezekia admin account

You do not need an OpenAI API key or OpenAI credits to use the MCP.

Enable the Ezekia MCP Connector app in ChatGPT

This step must be completed by a ChatGPT Owner or Admin with an Enterprise subscription. Terminology sometimes differs, but in ChatGPT:

If you are an owner, on the app screen, select Publish next to your app connector, review and tick any risks, and then Publish once again: If you are an admin without Publishing permissions, find your app Apps / Connectors and then select the 3 dots > URL > Share URL, and share this with your colleagues:
