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 | $0.04388 | $0.04388 |
| Opus 5 | $0.02194 | $0.02194 |
| Sonnet 5 | $0.00878 | $0.00878 |
| Haiku 4.5 | $0.00439 | $0.00439 |
Grade C, and why
camoufox-mcp AGENTS.md scanned grade C 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 7d 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.
Recursive force deletehighDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

Project Overview
This is a TypeScript-based MCP (Model Context Protocol) server that provides browser automation capabilities using Camoufox (a privacy-focused Firefox fork). The server exposes browser tools with bounded output and extensive privacy controls:
camoufox_status: return server, browser, queue, session, policy, and network-security posture status.browse: navigate once and return bounded text, HTML, metadata, diagnostics, and optional screenshot output.browse_snapshot: navigate once and return bounded visible text, ARIA snapshot data, and interactive element metadata.browse_sequence: navigate once, run a bounded CSS-selector action sequence, then return final content, snapshot data, diagnostics, and optional screenshot output.browse_links,browse_forms,browse_outline,browse_find: low-context page extraction tools.browse_screenshot,browse_console,browse_network_summary: focused screenshot and diagnostics tools.browse_session_*: short-lived isolated browser sessions with challenge pause/resume, best-effortattemptmetadata, and optional LLM-assisted provider playbooks whenCAPTCHA_AUTONOMOUS=true.

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.

camoufox-mcp AGENTS.md is an instructions file published in the GitHub repository whit3rabbit/camoufox-mcp (46 stars, last pushed 3d ago), licensed MIT. It adds 4,388 tokens to every session, about $0.0219 per session on Opus 5. A static security scan graded it C with 1 finding (recursive force delete).
