cli-anything-browser

A command-line tool for controlling a Chrome or Chromium browser through its accessibility tree, a text-based representation of page elements. It uses DOMShell to connect terminal commands to the open browser.

In plain words
What is it for?
Use it to open and navigate pages, read or search page content, click elements, type text, and inspect the current page.
Why use it?
It allows coding agents and scripts to navigate pages and interact with controls in a structured way.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade B, and why

cli-anything-browser scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Instruction-override phrasingmediumPrompt injection

Text telling the model to disregard its earlier instructions or safety rules is the shape of a prompt injection, whoever wrote it.

- Craft ARIA labels with manipulative text (e.g., "Ignore previous instructions")

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.
