What version of the Codex App are you using (From “About Codex” dialog)?
26.513.31313 (2867)
What subscription do you have?
API
What platform is your computer?
Darwin 25.4.0 arm64 arm
What issue are you seeing?
When I am connecting to MCP servers (in my case Notion and Linear), either:
- I use
codex mcp login notion,codex mcp login linearfrom command line, it opens a browser page with the url it gives asking to trust the127.0.0.1, i approve, it shows approved in the browser, then I force quit the codex app, and reopen the runtime, it is connected (This one works) - If I directly tell Codex to look at a ticket in Linear (I had the MCP authenticated before but it does not stays authenticated forever), it launches automatically the webpage for authentication, I click, web page says it is authenticated, but
The XXX MCP is configured, but its refresh token is expired/invalid. I’m going to re-authenticate it now; the skill notes a restart may be needed after OAuth, but I’ll see if this live session can pick it up.and then does not continue with this MCP
What steps can reproduce the bug?
- Go into a session with the coding agent, when Linear/Notion is not yet authenticated/authenticated before but not now;
- Ask Codex to see Linear ticket xxx, It will pop the authenticate web page, you click authenticate
127.0.0.1, and it will say authenticated, but then Codex will say:The XXX MCP is configured, but its refresh token is expired/invalid. I’m going to re-authenticate it now; the skill notes a restart may be needed after OAuth, but I’ll see if this live session can pick it up.
What is the expected behavior?
After I approve the authentication and the page says authenticated, Codex can access the MCP
