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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00042 | $0.00487 |
| Opus 5 | $0.00021 | $0.00244 |
| Sonnet 5 | $0.00008 | $0.00097 |
| Haiku 4.5 | $0.00004 | $0.00049 |
Grade A, and why
browse scanned grade A with 0 findings 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 8d 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Browse
Gives you direct access to a Chromium browser via the Browser Bridge MCP tools.
Available Tools
| Tool | Purpose |
|---|---|
browser_status |
Check connection and get active tab info |
browser_navigate |
Go to a URL |
browser_screenshot |
Capture visible area of a tab |
browser_evaluate |
Run JavaScript in the page context |
browser_click |
Click an element by CSS selector |
browser_fill |
Fill a form field by CSS selector |
browser_get_content |
Get text or HTML of a page or element |
browser_get_tabs |
List all open tabs |
browser_get_console |
Get console logs from a tab |
browser_wait_for |
Wait for a selector to appear |
Workflow
- Always start with
browser_statusto confirm the extension is connected. - Use
browser_navigateto go to the target page. - Use
browser_screenshotto see the current state before interacting. - After any interaction (click, fill), take another screenshot to verify the result.
Selector Tips
- Prefer
[data-testid="foo"]selectors when available. button:has-text("Submit")is NOT supported — usebrowser_evaluateto find elements by text content instead.- For scrolling, use
browser_evaluatewithdocument.querySelector('selector').scrollIntoView(). Do NOT usewindow.scrollBy()— it doesn't work with many framework scroll containers.
Gotchas
- Screenshots require a visible, focused tab. Minimized or background tabs will fail.
browser_evaluateresults must be JSON-serializable. Promises return{}— use synchronous expressions or await inside an IIFE and return a primitive/plain object.browser_fillworks with React. It uses native property setters to trigger React state updates.- All tools accept an optional
tabId. Omit it to target the active tab.
Task: $ARGUMENTS
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

browse is a skill published in the GitHub repository adbarc92/mcp-browser-bridge (1 stars, last pushed 9d ago), licensed MIT. It adds 42 tokens to every session and 487 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.

signed-in-browser
Drive the browser the user is already signed into, instead of a cold automation profile. Use when a task lives behind a login — a dashboard, an admin console, an internal tool, a ticket queue, a bank or billing page, webmail, a social account — or when a scripted login is failing on SSO, MFA, CAPTCHA or bot detection.…

Submit to Hacker News, including Show HN, by driving a signed-in browser. Use when launching a product, tool or MCP server, or when a submission needs its customary author comment. Covers the title rules, when a Show HN is allowed, the url-or-text choice, and how to tell a real submission from a silent failure.
