doesn´t work.
doesn´t work.
This doesn´t work. impossible to connect to it´s MCP from any agent. You are correct: the Composio instructions in that screenshot are no longer current for your ChatGPT Plus account.
What changed
On 9 July 2026, OpenAI replaced the former Apps directory with the Plugin Directory. Standard integrations are now connected through:
ChatGPT → Settings → Plugins
or
Sidebar → Plugins → select plugin → Connect
After installation, plugins/apps are invoked with an @ mention or through + → More in a chat.
I checked the Plugin Directory available to this account, and Composio is not currently listed as an installable plugin.
Manual Composio MCP connection
The manual Create app → paste MCP URL route still exists, but OpenAI now restricts it by plan:
Business, Enterprise and Edu: full MCP, including write and modify actions.
Pro: custom MCP with read/search/fetch permissions only.
Plus: custom MCP creation is not currently listed as supported.
That is why your Plus account does not show Developer Mode or Create app, despite Composio’s page claiming Plus support. OpenAI’s current documentation takes precedence over the Composio guide.
Current supported setup for full Composio access
With a Business workspace, as an owner/admin:
Open ChatGPT Web. Custom MCP setup is web-only.
Open Workspace settings → Apps → Create.
Enable Developer Mode when prompted, or under Settings → Apps → Advanced Settings.
Enter a name such as Composio.
Paste the same endpoint:
Select the offered authentication mechanism.
Click Scan Tools.
Complete the Composio browser authorization.
Click Create.
Open a new chat and select the draft Composio app from the tools menu.
The Composio endpoint itself remains current; the outdated part is its ChatGPT plan eligibility and navigation instructions.
Result for your account
ChatGPT Plus: BLOCKED for manually adding the Composio MCP.
The Composio dashboard loaded. I see a login page. Here's what I need you to do:
Option 1 (easiest): Open your own browser and go to to log in. Once authenticated,
I can walk you through the setup from there.
Option 2: You can log in through my browser session. Click the "Sign in to Composio" button and I'll try to
follow along.
The challenge is — my browser is headless, so I can't actually type your credentials or interact with OAuth flows
that require your real browser.
Best path for Composio email access:
1. You log into composio in your own Chrome
2. Connect your Outlook/Microsoft 365 account there (it supports Outlook as a connection)
3. Get your Composio API key
4. I set up the MCP server connection with your key
Want me to try clicking the sign-in button to see what happens, or should we go with you handling the login in
your real browser first? only problem they do not give you API key. it is a waste of time
