Codex CLI 0.142.2 improves tool discovery and proxy login

Codex CLI 0.142.2 makes it easier for the agent to find external tools by using MCP tool search by default when the setup supports it. It still keeps compatibility with older models and other providers. On macOS, authentication can follow system proxy, PAC, and WPAD settings when respect_system_proxy is turned on. The previous 0.142.1 release added similar optional Windows system proxy support for login, including PAC, WPAD, fixed proxies, and bypass rules.

Plugins can now provide separate logos for dark mode, and apps can show richer safety-check screens using server-provided visibility data and faster-model metadata. The fixes are mostly practical. Expired Amazon Bedrock credentials now lead to useful recovery guidance instead of a vague authorization error. Remote stdio MCP servers can accept absolute working folders written in the remote platform’s own path format.

Remote HTTP(S) image input problems now return clearer validation errors that the model can see, while inline data URLs and local images still work. PowerShell commands with executable parts that the safety classifier cannot inspect now require approval, and Code Mode warns when the selected model is missing required metadata. Versions 0.142.3 and 0.142.4 were maintenance releases with no user-facing changes.
