I have similar issue when using ChatGPT with custom connector. It is not visible inside the projects. Outside the projects connectors are accessible but only for limited number of tool calls - after 3-5 calls agent tells me that “list_resources returns only {finite: true}" and it cannot finish the work.
So what I tested:
Start new conversation outside Projects: ask ChatGPT about access to connector - PASS
Move this conversation to any Projects, freshly created or older does not matter: ask ChatGPT about access to connector - FAIL - no connectors are available.
Move conversation out of the Projects: ask ChatGPT about access to connector - PASS - connector available again.
I have the same issue. Replying to boost as I think it is a critically important issue.
Summary of my similar/same issue:
MCP Apps created via Admin → Apps can enter a partially registered state where they work in non-Project chats but are not discoverable or usable inside Projects. Oddly the app appears inside projects as an app in the drop down menu if first invoked outside a Project, but is still not usable. This creates inconsistent behavior, breaks the documented “Apps are workspace-wide” model, and prevents MCP usage in Projects.
which says “Are connectors supported in projects? Connectors are currently not supported.”
Connectors → are now apps (they got renamed)
So maybe this is by design? but frankly who isn’t working primarily in projects?! Simply for organisation of chats if nothing else.
WORKAROUND:
The only workaround I have found is that you can move a chat in and out of a project, and the app connection appears to work whilst the chat is outside the project and not whilst it is inside the project. You can then in theory:
move chat out of the project
run prompt that calls the app
move the chat back into the project
run prompts that relate to project context/scope/documents
and so on….
Maybe this workaround helps someone.
But seriously, this is madness, please fix!
PS: chatgpt is also super happy to lie about this, and just pretend that it can see the app and make up a fake output.
You are right about Connectors support inside projects. Just my assumption was wrong.
I have used Connectors in Projects for about 2 months and it just stopped working about week ago - at the time when Connectors stopped working in Projects, some members posted problems with their Connectors; I thought it may be corelated to my observations, here is the link to original post: https://community.openai.com/t/chatgpt-not-using-connected-local-app-sdk/1369390
Commenting to help boost priority of this issue. I would love for my projects to be able to see my app but it can’t find any tools unless I’m outside of the “project” interface.
I also just got alerted to this issue by our workspace users. This is a big issue for us, users have been using our custom connector (now “App”) in projects for months. This was the main reason we migrated to ChatGPT business. Please take a look!
This is a blocker for us as well. We are exposing data agents to our business users, and we want them to be able to use project instructions to provide their own preferred outputs. Not having this capability is a blocker. If it is not fixed, we’ll have to consider other platforms that offer this capability (e.g., Claude).
The more I work with projects, more broken it appears. Files attached at the Project root, aren’t accessible to chats within the project. And the idea of using an external repository, works great till learning that app connectors aren’t available inside projects.
I’m seeing the same problem. The strange part is that I used an n8n MCP connector in this same project a few weeks ago with no issues.
Now, none of the attached tools are being detected. ChatGPT initially claimed this behavior was normal, until I shared the entire previous thread showing that it did work before.
Something has clearly changed. OpenAI needs to acknowledge this as a bug and fix it. This is critical for Enterprise users.
Apps aren’t a feature in projects just yet. I’ve filed an issue and referenced this thread to bring attention to it. I also noted in the issue that custom apps do show up under the + → More… menu in the composer area while in a Project, and they can be selected, but they don’t do anything yet.
What’s strange is that this used to work. The timing of when it stopped lines up almost exactly with the rename from connectors to apps.
I can still see custom apps in chats that live inside a Project, but only in the web app. They don’t appear at all in the Windows desktop app. Even when an app is visible in a Project chat, attaching or running it does nothing.
If I move the chat out of the Project, the app works again, but I lose all the Project-level instructions and context. That tradeoff makes this feel less like a bug and more like a questionable product decision.
The most annoying part for me, is that apps like Notion can’t be utilized for team collaboration, when ChatGPT is entirely unable to connect to team workspaces. This severs the only use case Notion offers for use with ChatGPT as an integrated app.
Solo projects suffer from a similar issue, with ChatGPT still struggling with context retention between chats, even ones within a project. This stops the connection between the source of truth and discussion with ChatGPT.
Shared Projects in Business workspaces for team collaboration is essentially useless without the ability to access company knowledge layer and connected apps
Noted. There are a lot of really cool use cases for this, for sure. The team is aware of the desire for this. I don’t have optics to comment on timeline, though.
