Please refer to this documentation for details about how to configure MCP servers for use with codex.

@etraut-openai it was working fine last week, it stopped working, i don't know if it was from the update to the 0.50 or the extensions updates. We should have this standarized, not having a config.toml and claude another thing, and others their thing. Makes sense if .vscode is detecting and Copilot chat is also detecting that Codex should also detect it.

In the config.toml is also not detecting:

Maybe you were using the copilot agent by mistake but Codex has never supported .vscode/mcp.json

From the top of your screenshot, it definitely does see the stripe mcp, you just need to log in with the codex CLI using codex mcp login stripe

We're going to add UI for MCP management in the extension but don't have it yet.
