Written for Claude Code and Codex and OpenCode: Claude Code plugin machinery, but also the file is AGENTS.md. Also seen: mentions AGENTS.md; mentions Codex; built for openclaw.

This is whit3rabbit/camoufox-mcp's own configuration. It tells Claude Code, Codex and OpenCode how to work on camoufox-mcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything camoufox-mcp configures →

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 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-effort attempt metadata, and optional LLM-assisted provider playbooks when CAPTCHA_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.
