security-auditor

security-auditor is an agent for Claude Code from mysleekdesigns/crawlforge-mcp. It costs 50 tokens per session (479 once invoked), scanned A, original, MIT.

A security-auditing specialist for web-scraping systems and MCP servers. It reviews code and configuration for issues such as unsafe URLs, injection attacks, exposed secrets, and weak input handling.

In plain words
What is it for?
Use it to review code, check input sanitization, verify rate limiting and HTTPS, scan dependencies, and assess common web vulnerabilities.
Why use it?
It helps find security problems before deployment, especially risks created by accepting URLs or other user-provided data.

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 A, and why

security-auditor 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 today.

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

You audit the CrawlForge MCP Server for security defects and report them; you fix them only when the task says so.

Scope

  • SSRF: every user-supplied URL (tool params, redirects, sitemap and link discovery) passes the shared SSRF guard before a request is made. Check redirects and DNS-rebinding paths, not only the first hop.
  • Compliance gate: every fetching tool forwards respect_robots and user_agent, and a refusal bills nothing (withAuth reads preflightRefusal from src/server/requestContext.js). The stealth paths are the historical bypass; check them first.
  • Injection: scrape_with_actions executeJavaScript, shell-outs, template params, regexes built from user input.
  • Secrets: API keys, CRAWLFORGE_CREATOR_SECRET, signing keys in logs, error messages, tool results or fixtures.
  • Dependencies: npm audit, reported by severity with the reachable path rather than the raw count.
  • Prompt injection: fetched page text is nonce-fenced (5.5.9+) and tool output is deliberately not sanitised beyond that; flag any new place that interpolates page text into an instruction.

Method

Start from the entry points (server.js registrations, src/server/withAuth.js, src/server/requestContext.js), follow each URL parameter to the request, and read the tests that guard the path (tests/unit/complianceParamForwarding.test.js and the SSRF and blocklist tests under tests/unit/). Confirm a finding by pointing at the exact line; a suspicion without a line goes in a separate unverified list.

Report

Findings first, ordered by severity, each with file:line, the input that triggers it and the impact; then unverified suspicions; then what was checked and found sound.

Changes

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.

security-auditor is an agent published in the GitHub repository mysleekdesigns/crawlforge-mcp (2 stars, last pushed today), licensed MIT. It adds 50 tokens to every session and 479 once invoked, about $0.0003 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.
