How to connect GitHub to ChatGPT

1. 1. Enable GitHub in Metorial

   In your Metorial portal, enable the GitHub MCP server and sign in with the account that owns the data. Access stays governed by your team policies.

2. 2. Add a custom MCP server

   On ChatGPT web, open Plugins, select +, then Add custom MCP server.

3. 3. Paste your Metorial MCP URL

   Name it Metorial, paste your Magic MCP URL (<your-magic-mcp-url>), choose OAuth and accept the risk notice.

4. 4. Create and install the plugin

   Select Create as a plugin, install it and sign in to load GitHub tools.

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