Why this grade

  • NETWORK_NO_FIXED_HOST Low

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

    src/intervals_icu_mcp/client.py, line 196 oldest: Oldest date to fetch (ISO-8601 format)

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    CLAUDE.md, line 19 make auth # Set up Intervals.icu credentials (.env)

  • PERMISSION_SHELL_DECLARED Note

    Runs shell commands, and the manifest or description says so.

    .github/scripts/openapi_diff.py, line 81 out = subprocess.check_output(

  • SECRETS_ENV_READ Note

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

    scripts/smoke_eval.py, line 144 if not os.environ.get("ANTHROPIC_API_KEY"):

  • OBFUSCATION_FILE_OVER_READ_CAP Note

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

    openapi-spec.json, line 1 {"openapi":"3.0.1","info":{"title":"Intervals.icu API","version":"v1.0.0"},"servers":[{"url":"https://intervals.icu"}],"security":[{"APIKey":[],"AccessToken":[]}],"paths":{"/api/v1

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.
