Am I dumb or does Codex for Mac just not support any xcodebuildmcp interactions (like swipe, tap, etc.)? The cli version does properly for the same project. Anyone manage to get that to work? Is MCP setup different?

Okay figured it out, if you have *project* level config.toml, the following works fine for the codex-cli but not codex-mac:

[mcp_servers.XcodeBuildMCP]
command = "xcodebuildmcp"
args = ["mcp"]

Adding the environment specifically seems to fix the Mac app, and I just moved it to global codex config:

env = { XCODEBUILDMCP_ENABLED_WORKFLOWS = "simulator,ui-automation" }
