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 | $0.02373 | $0.02373 |
| Opus 5 | $0.01187 | $0.01187 |
| Sonnet 5 | $0.00475 | $0.00475 |
| Haiku 4.5 | $0.00237 | $0.00237 |
Grade B, and why
bwb-browser AGENTS.md 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 4d 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.
Reads agent configuration directoriesmediumAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

What is bwb?
Browser Without Bloat — a lightweight MCP server that gives any AI agent browser superpowers. 76KB. 26 tools. Zero heavy dependencies.
While other MCP browser tools ship a full browser binary (Playwright MCP = ~250MB, Puppeteer MCP = ~400MB), bwb uses raw Chrome DevTools Protocol (CDP) — the protocol Chrome speaks natively. It auto-detects the browser already on your system.
Built on Termux/Android. Runs everywhere. Weighs nothing. Browser automation from your phone.
🔥 Zero-Config Install (5 seconds)
Don't copy-paste configs. Don't hunt for the right path. Just:
npm install -g bwb-browser
bwb --setup
That's it. bwb --setup auto-detects every AI agent on your machine (OpenCode, Antigravity, Claude Code, Hermes, Cline, Continue, Codex CLI), writes the correct MCP config for each, detects Chrome/Chromium, and prints a summary. Close and reopen your agent — tools are ready.

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.

bwb-browser AGENTS.md is an instructions file published in the GitHub repository krshforever/bwb-browser (15 stars, last pushed 28d ago), licensed MIT. It adds 2,373 tokens to every session, about $0.0119 per session on Opus 5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
