@fatbobman thank you for writing this up! I'm trying to follow your article to configure additional MCP servers for Codex, but the built-in agent insists that the only available MCP is xcode-tools. The config changes are fine, Codex CLI works just fine. Is there some sort of internal allowlist in Xcode? Or is this an environment issue?

@andrii_ch @fatbobman Two things to investigate via my gist https://gist.github.com/everyplace/0a1e2637261325ea1d47447f4085bf37?utm_source=Fatbobman%20Blog&utm_medium=web 1) check the logs. Sometimes you’ve configured it correctly, but the paths for dependencies for the MCP server are wrong. Look at how injecting the PATH. Check the logs to see if there’s something strange / failing. 2) you could ignore this and set the dangerous flag to make it figure itself out.
