  "_comment": "Codex-side [mcp_servers.<name>] keys certain MCPs need that codex-cli 0.150.1 offers NO way to set: `codex mcp add` has no flag for them, and config.toml's [mcp_servers.*] tables are inert (measured -- editing one there does not change what `codex mcp list` reports). sync_mcp_registrations.ps1 reports these after registering so the gap stays visible instead of looking complete. Re-check on each codex-cli upgrade; delete an entry once a real interface exists and the key is set.",
