Codex CLI 0.158.0-alpha.10

0.158.0-alpha.9→0.158.0-alpha.10·September 24, 2026 at 10:18 PM UTC

Alpha patch: codex mcp add can take an OAuth client secret for pre-registered clients.

Changelog

  • [new] codex mcp add accepts --oauth-client-secret so you can supply an optional client secret when the MCP server uses a pre-registered OAuth client.
  • [changed] Bash, fish, and zsh completions for codex mcp add include --oauth-client-secret.

Under the hood

  • TUI groundwork for feedback upload, prompt suggestions, and markdown copy.
  • OpenTelemetry config expanded, including guardian-assessment support.
  • MCP attribution and related config types were refined; realtime-history presentation and tool catalog-parameter plumbing were removed.
  • Lockfile updates.

Upgrade notes

  • Reinstall or re-source shell completions if you rely on them for codex mcp add.
  • When adding a streamable HTTP MCP server with a pre-registered OAuth client, pass --oauth-client-secret alongside --oauth-client-id as needed.
