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

Rescanned at commit 9dc9d6510aa0, unchanged since the check below.

PERMISSION_DELETE_FILES SECRETS_PATH_DOTENV

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    src/cli.test.ts, line 17 fs.unlinkSync(defaultEnvFile);

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    src/cli.test.ts, line 7 const defaultEnvFile = path.join(process.cwd(), '.env.mcp');

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.
