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

Rescanned at commit 1e80cc98a703, unchanged since the check below.

NETWORK_UNNAMED_HOST SECRETS_PATH_DOTENV OBFUSCATION_ENCODED_BLOB SECRETS_ENV_READ

Why this grade

  • NETWORK_UNNAMED_HOST Low

    Calls a fixed host that the description does not name.

    CLAUDE.md, line 430 curl -s "https://api.github.com/repos/Vortiago/mcp-outline/commits/<SHA>/check-runs" \

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    start_server.sh, line 10 export $(grep -v '^#' .env | xargs)

  • OBFUSCATION_ENCODED_BLOB Low

    Contains a long base64 shaped string in a file that should be readable.

    uv.lock, line 1 version = 1

  • SECRETS_ENV_READ Note

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

    src/mcp_outline/server.py, line 177 if not os.getenv("OUTLINE_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.
