devspace chatgpt workspace no actions issue

[hcchou1232]

ChatGPT Workspace App imports no Actions, while MCP Inspector successfully lists and calls tools

Summary

I'm trying to use DevSpace with the new ChatGPT Workspace Apps (Business
workspace).

The MCP server works correctly in MCP Inspector, but when importing the
same server into ChatGPT Workspace Apps, the app is created with no
Actions available.

It appears that ChatGPT never performs tools/list after the app is
created.

Environment

• Windows 11
• Node v24.14.1
• npm 11.11.0
• Git 2.53.0.windows.1
• DevSpace @waishnav/devspace 1.0.4
• Streamable HTTP over Cloudflare Tunnel

DevSpace

Started with:

export DEVSPACE_TRUST_PROXY=1
npx @waishnav/devspace serve

devspace doctor reports everything OK.

MCP Inspector

Successful flow:

• OAuth
• initialize
• tools/list
• tools/call

Tool Open workspace is listed and executes successfully.

Example:

{
  "workspaceId": "...",
  "root": "C:\\Users\\HCC\\earth\\universe",
  "mode": "checkout"
}

ChatGPT Workspace Apps

Using the same public MCP endpoint:

• OAuth succeeds
• App creation succeeds
• App appears in Workspace
• Actions page shows: This app has no available actions.

ChatGPT reports the app has no callable tools.

Server logs

Observed during app creation:

POST /mcp -> 401
GET /
GET /.well-known/openid-configuration -> 404
POST / -> 201

ChatGPT never sends:

initialize
tools/list
tools/call

while MCP Inspector does.

Verified

• Cloudflare tunnel works
• OAuth works
• DCR registration succeeds
• devspace doctor passes
• MCP Inspector initialize/tools/list/tools/call all succeed
• ChatGPT Workspace imports zero Actions

Question

Is there any known compatibility issue between DevSpace 1.0.4 and the
new ChatGPT Workspace Apps?

Is there any additional MCP metadata or capability that ChatGPT
Workspace expects beyond what MCP Inspector requires?
