• Type @ and pick the plugin. The selection applies to that message only, so @mention it again when a follow-up needs fresh Gumroad 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 Gumroad 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 Gumroad 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".
