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

NETWORK_UNNAMED_HOST SECRETS_PATH_DOTENV SECRETS_ENV_READ

Why this grade

  • NETWORK_UNNAMED_HOST Low

    Calls a fixed host that the description does not name.

    .github/workflows/release.yml, line 295 fetch('https://registry.modelcontextprotocol.io/v0/servers?search=' + encodeURIComponent(name))

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    .gitignore, line 6 .env

  • SECRETS_ENV_READ Note

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

    packages/core/scripts/probe-live.mjs, line 29 const apiKey = process.env.TYPESAFE_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.
