Do I need an API key to connect Google Tag Manager to ChatGPT?

No. You sign in to Google Tag Manager once through Metorial, and ChatGPT uses that connection. No API keys go into ChatGPT's settings.

Which Google Tag Manager tools can ChatGPT use?

All 11 Google Tag Manager tools your team allows, such as Manage User Permission, Manage Container, Manage Trigger. Admins can narrow that list per team.

Can I control which teammates use Google Tag Manager in ChatGPT?

What if ChatGPT doesn't show Google Tag Manager tools?

Workspace policy controls it. On Enterprise and Edu, an admin grants the permission to create plugins with MCPs; ask them to enable it for you.

Once Google Tag Manager is enabled in Metorial, teammates sign in with SSO and get the same connection in ChatGPT, with only the tools their role allows.

One link covers every app you approve. See how the MCP gateway handles access, roles and audit logs for the whole company.

Manage User Permission: Create, list, get, update, or delete user permissions for a GTM account.
Manage Container: Create, retrieve, update, or delete a GTM container.
Manage Trigger: Create, list, get, update, or delete triggers in a GTM workspace.

Type @ and pick the plugin. The selection applies to that message only, so @mention it again when a follow-up needs fresh Google Tag Manager data.
For write actions, ChatGPT may ask you to confirm first, depending on the app permissions and the action.
Once published for a workspace, ChatGPT keeps a snapshot of the tool list. When your team adds Google Tag Manager tools in Metorial, an admin refreshes the actions in Workspace settings before they appear.
You can use several apps in one prompt, for example read Google Tag Manager data and then create a ticket in another app.

Add custom MCP server is missing: Workspace policy controls it. On Enterprise and Edu, an admin grants the permission to create plugins with MCPs; ask them to enable it for you.
The plugin exists but no tools appear: Creating the plugin is not enough: install it from your plugins, then start a new conversation so ChatGPT loads its tools.
ChatGPT answers without using the tools: Pick the plugin with @ in the composer and name the action you want, for example "use Metorial to look up the latest ticket".
