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

PERMISSION_DELETE_FILES NETWORK_NO_FIXED_HOST SECRETS_PATH_UNCONFIRMED INSTALL_DOCUMENTED_INSTALLER SECRETS_ENV_READ OBFUSCATION_FILE_OVER_READ_CAP

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    papers_mcp/telemetry.py, line 194 out = subprocess.check_output(

  • NETWORK_NO_FIXED_HOST Low

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

    install.sh, line 75 curl -s -m 3 -X POST "$TELEMETRY_URL" -H "Content-Type: application/json" -d "$payload" >/dev/null 2>&1 || true

  • SECRETS_PATH_UNCONFIRMED Low

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

    papers_mcp/sources/semanticscholar.py, line 26 _KEY = os.getenv("FIND_RESEARCH_PAPERS_MCP_S2_API_KEY", "").strip()

  • INSTALL_DOCUMENTED_INSTALLER Note

    Documentation shows an installer that pipes a download into a shell.

    AGENTS.md, line 13 curl -fsSL "https://papers.builditwithai.xyz/install" | bash

  • SECRETS_ENV_READ Note

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

    papers_mcp/sources/semanticscholar.py, line 26 _KEY = os.getenv("FIND_RESEARCH_PAPERS_MCP_S2_API_KEY", "").strip()

  • 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.

What was checked
