ChatGPT connects to Noux through Plugins (OpenAI’s UI for remote MCP servers). You sign in with your Noux account; no manual token copying required.
ChatGPT OAuth is granted mcp:read and mcp:write scopes (all Noux MCP OAuth connections use both). ChatGPT can query your organization’s data and call write tools (comments, invitations, notifications, key document spread, mutual action plans) as you — limited by your room permissions in Noux. ChatGPT may ask you to confirm before each write action. Reconnect the connector if you connected before this change and need write tools.

​
Before you start

  • A Noux account with access to your organization
  • ChatGPT on the web (chatgpt.com) — custom MCP connectors are not available on mobile apps
  • A paid ChatGPT plan (Plus, Pro, Business, Enterprise, or Edu)
  • Network access to https://mcp.noux.app and https://noux.app
On ChatGPT Business, Enterprise, or Edu, a workspace admin or owner must enable custom MCP connectors before members can create apps. See Business and Enterprise workspaces below. You do not need to create a personal Bearer token for ChatGPT — OAuth handles authentication.

​
Step 1 — Enable Developer Mode

  1. Open ChatGPT in your browser.
  2. Go to Settings.
  3. Open Security and login.
  4. Turn on Developer mode (marked ELEVATED RISK).
OpenAI has moved this toggle between Settings → Apps → Advanced settings and Settings → Security and login across releases. If you do not see it under Security and login, check Apps → Advanced settings instead.
Leave Lockdown mode off — it can block connectors that reach external services.

​
Step 2 — Create the Noux connector

  1. Go to Settings → Plugins (or Workspace settings → Apps on Business if your admin publishes workspace apps).
  2. Click Create (or +).
  3. Fill in the form:

​
Advanced settings

For the standard Noux setup you do not need extra OAuth credentials:
  • Select OAuth as the authentication type
  • Leave any OAuth Client ID or Client Secret fields empty if shown
Noux registers ChatGPT automatically using OAuth 2.1 dynamic client registration. You do not need to paste credentials from the Noux app.
Only add connectors from developers you trust. The URL must be exactly https://mcp.noux.app/mcp — including the /mcp path.
Click Create (or Save). On Business, admins must publish the app in Workspace settings → Apps before other members can use it.

​
Step 3 — Connect and sign in

  1. Start a new chat on the web (or open an existing one).
  2. Enable the Noux connector from the chat tools or plugins menu, or ask ChatGPT to use Noux data — the first tool call launches OAuth.
  3. Your browser opens the Noux authorization flow:
    • Sign in to noux.app if you are not already logged in
    • Review the consent screen — it explains what MCP access ChatGPT is requesting
  4. Click Allow access.
ChatGPT receives an OAuth access token scoped to your user and organization. The connector should show as connected.

​
Step 4 — Verify it works

Ask ChatGPT something that uses Noux data, for example:
  • “Use Noux to call get_info and tell me my organization id.”
  • “List my Noux sales rooms.”
  • “Summarize recent activity in my Noux organization.”
ChatGPT should invoke Noux MCP tools (see the tool reference). If tools are not available, remove and recreate the connector, re-authorize from Settings → Plugins, or start a new chat.

​
What ChatGPT can access

Through OAuth, ChatGPT acts as you in your Noux organization with mcp:read and mcp:write scopes. That includes:
  • Rooms, members, visitors, and invitations
  • Room conversations and comments
  • Notetaker meetings, transcripts, summaries, and coaching
  • Organization activity for reporting
  • Write tools such as posting comments, sending invitations and update notifications, spreading key documents, and creating or updating mutual action plans — subject to your room permissions
ChatGPT confirms with you before executing write actions. This is different from Claude Desktop, which may invoke write tools without a separate confirmation step. For automation without ChatGPT, use a personal Bearer token in Cursor or scripts, or the REST API with an organization API key.

​
Business and Enterprise workspaces

On ChatGPT Business, only workspace admins and owners can enable Developer mode and create or publish MCP apps. Workspace admin — enable custom connectors
  1. Open Workspace settings (not personal Settings).
  2. Go to Permissions & roles → Connected data.
  3. Turn on Developer mode / Create custom MCP connectors.
Create and publish the Noux app
  1. In Workspace settings → Apps, click Create (Developer mode may be enabled here automatically).
  2. Use URL https://mcp.noux.app/mcp and OAuth authentication.
  3. Test the app, then publish it for your workspace.
Each admin must also enable Developer mode in their own Settings → Security and login if they create apps from personal settings.

​
Troubleshooting

For Cursor, automation scripts, or other clients that do not support Plugins OAuth, use a personal Bearer token instead.
ChatGPT can connect with a Token auth type and a personal Bearer token instead of OAuth. This works for quick tests but is not recommended for regular use — tokens must be copied manually, rotated by you, and do not support the same one-click sign-in flow as OAuth.
  1. Create a token under Integrations → MCP.
  2. In Settings → Plugins → Create, set Authentication to Token and paste the token.
  3. Use connector URL https://mcp.noux.app/mcp.
Prefer OAuth for production and team use.
