MCP tools in TRUSTED project are not shown in Codex Desktop, but they still work.

What issue are you seeing?

MCP tools are not visible in Codex Desktop for trusted project, even though they are connected and working. The tools can still be invoked successfully, but they do not appear in the interface as expected.

What steps can reproduce the bug?

1. Make sure the project is trusted.
2. Add the following configuration to project_folder/.codex/config.toml:

model = "gpt-5.4"

[mcp_servers.todoist]
command = "npx"
args = ["@greirson/mcp-todoist"]
env = {"TODOIST_API_TOKEN" = "..."}

1. Run codex app in that folder.
2. Verify that the Todoist MCP server works by sending the prompt: "show my tasks for today". The tasks are returned successfully.
3. However, the /mcp command in Codex Desktop shows no MCP servers.
4. If I run the Codex CLI app instead, it does show this MCP server.

Example:
<img width="814" height="485" alt="Image" src="https://github.com/user-attachments/assets/23d8823c-393c-40fe-9906-1e1e717853ce" />

In cli there is no such problem:
<img width="1216" height="470" alt="Image" src="https://github.com/user-attachments/assets/0cb719b8-0a98-4f5d-9a2d-4fa11c29af90" />

What is the expected behavior?

If the MCP server is configured and usable, it should also appear in /mcp in Codex Desktop.
