Grades are a hygiene check, not a security guarantee.

MCP, MCP server

Grade B

Minor issues only, no Medium or High. Worth a quick look at the findings below before installing.

Graded by PlugVetRubric v2

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

Rescanned at commit 69ce021795c4, unchanged since the check below.

PERMISSION_DELETE_FILES NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_HOST SECRETS_PATH_DOTENV

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    scripts/package-smoke-test.ts, line 636 fs.rmSync(tempDir, { recursive: true, force: true });

  • NETWORK_NO_FIXED_HOST Low

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

    scripts/package-smoke-test.ts, line 351 const healthRes = await fetch(`http://127.0.0.1:${testPort}/healthz`);

  • NETWORK_UNNAMED_HOST Low

    Calls a fixed host that the description does not name.

    scripts/package-smoke-test.ts, line 351 const healthRes = await fetch(`http://127.0.0.1:${testPort}/healthz`);

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    .gitignore, line 9 .env

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.
