## Summary

Simon Willison announced the open‑source plugin llm-keys-ui version 0.1, aimed at developers who run coding agents on remote machines. The tool lets users store and retrieve LLM provider API keys without copying them into a ChatGPT session, addressing a common security inconvenience.

The plugin works with Codex Remote. Users start the UI with a command such as `uvx --with llm-keys-ui llm keys-ui --all`, which returns a local or Tailscale URL where keys can be added. Later, an agent can fetch a stored key via `llm keys get anthropic` (or any other provider) as part of its shell workflow. The approach keeps secrets out of terminal history and simplifies key rotation for multiple agents.

By exposing a lightweight web interface for key management, the plugin reduces the risk of accidental key leakage while keeping the workflow entirely command‑line driven. It joins a series of recent posts by Willison on LLM tooling, including work on GPT‑6 Astra routing and analysis of AI‑driven attacks on RubyGems.

## Key points

- llm-keys-ui 0.1 adds a web UI for storing LLM API keys used by remote coding agents.
- Invoked via `uvx --with llm-keys-ui llm keys-ui --all` to receive a local or Tailscale URL.
- Stored keys are accessed later with `llm keys get <provider>` such as Anthropic.

## Why it matters

Secure, on‑the‑fly key handling prevents accidental exposure of LLM credentials, making remote agent workflows safer for developers.
