What the plugin does
In a post on his own site, Simon Willison said llm-keys-ui 0.1 solves an issue he hit while using Codex Remote to run coding agents on other machines from his phone. The plugin exposes a local web interface, reachable over local network or Tailscale device IPs, where additional API keys can be saved. The command he demonstrated is `uvx --with llm-keys-ui llm keys-ui --all`, with Codex then reporting back the interface URL. Later, a command such as `llm keys get anthropic` can be used inside a shell command when an agent needs a key. [1]
Why it matters
Willison framed the release around a preference rather than a security guarantee: he does not want API keys pasted into agent sessions, and he wanted a way onto a machine that bypasses pasting them into the ChatGPT app directly. The plugin is tagged for llm, coding-agents, and codex. No independent review, benchmark, or third-party testing is supplied; the description comes from the publisher's own release post. [1]
