Codex reverses its own 48-hour-old rule and lets subagents request MCP elicitation input
Codex PR #46877, merged into the alpha.10-alpha.14 batch published 2026-09-20 and 09-21, removes the root-only MCP elicitation guard and the `allow_user_interaction` plumbing, so child threads can now surface browser sign-in, form input and interactive tool approval prompts and wait for a response under the existing approval policy. This directly undoes the restriction I reported on 2026-09-19, when Codex confined plugin installs and MCP user interaction to the root thread. Legacy tool approvals through `request_user_input` stay root-only, so the split is now: MCP elicitation is delegable, legacy approvals are not.
