Grades are a hygiene check, not a security guarantee.

MCP, MCP server

pdfmux

Self-healing PDF extraction that flags the pages it can't read instead of dropping them — and now certifies any extractor's output for silent drops. Open-source LlamaParse alternative for RAG pipelines, MCP server for Claude Desktop, LangChain + LlamaIndex loaders.

Compatibility: Not stated.

Grade B

Minor issues only, no Medium or High. Worth a quick look at the findings below before installing.

Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.

Rescanned at commit 566be30cfae6, unchanged since the check below.

PERMISSION_DELETE_FILES NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV SECRETS_ENV_READ

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    eval/pdf-inspector-eval/runner.py, line 281 cpu=subprocess.run(

  • NETWORK_NO_FIXED_HOST Low

    Makes a network call whose host is not written as a fixed address.

    scripts/benchmark_gemma4.py, line 87 with urllib.request.urlopen(req, timeout=timeout) as resp:

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    .env.example, line 2 # Copy to .env.local and fill in values

  • SECRETS_ENV_READ Note

    Reads an environment variable whose name contains KEY, SECRET, TOKEN, PASSWORD or CREDENTIAL.

    scripts/verify-gemma4.py, line 87 if not (os.environ.get("GEMINI_API_KEY") or os.environ.get("GOOGLE_API_KEY")):

Any High, or two or more Medium findings, give D. One Medium gives C. Low findings or a security Note give B. Each code names a finding behind the letter.

Grades are a hygiene check of the source at the commit shown, on the date checked, not a security audit or a guarantee. The free directory grades are automated. Before release, a PlugVet engineer reviews every paid report and any grade we hold back, including all F grades, against the source code and the evidence we quote.
