Graded by PlugVetRubric v2

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

Rescanned at commit 1811b604eeb1, unchanged since the check below.

NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV SECRETS_ENV_READ OBFUSCATION_FILE_OVER_READ_CAP

Why this grade

  • NETWORK_NO_FIXED_HOST Low

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

    mcp/src/fetch.ts, line 12 * Plain fetch (free quota) or, when a private key is configured, an x402-paying fetch

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    scripts/doctor.ts, line 8 * (defaults to PUBLIC_BASE_URL from .env, then http://localhost:4021)

  • SECRETS_ENV_READ Note

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

    mcp/src/index.ts, line 18 const doFetch = createFetch(process.env.X402_PRIVATE_KEY);

  • OBFUSCATION_FILE_OVER_READ_CAP Note

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

    data/names/dict.json, line 1 {"builtAt":"2026-09-12T19:40:36.594Z","sources":["mecab-ipadic Noun.name.csv (NAIST license - see IPADIC-COPYING.txt)","japanese-personal-name-dataset (MIT - see LICENSE.txt)"],"co

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.
