PERMISSION_DELETE_FILES NETWORK_NO_FIXED_HOST SECRETS_PATH_UNCONFIRMED SECRETS_ENV_READ OBFUSCATION_FILE_OVER_READ_CAP

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    src/zotero_mcp/_helpers.py, line 793 shutil.rmtree(temp_dir, ignore_errors=True)

  • NETWORK_NO_FIXED_HOST Low

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

    src/zotero_mcp/library.py, line 1230 async def fetch(

  • SECRETS_PATH_UNCONFIRMED Low

    The Secrets check reports a credential or environment file, but no quoted line shows a recognisable path.

    src/zotero_mcp/_helpers.py, line 343 api_key = os.environ.get("ZOTERO_API_KEY", "")

  • SECRETS_ENV_READ Note

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

    src/zotero_mcp/_helpers.py, line 343 api_key = os.environ.get("ZOTERO_API_KEY", "")

  • OBFUSCATION_FILE_OVER_READ_CAP Note

    A file was over the read cap and was not fully read.

    uv.lock, line 1 version = 1

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.
