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

NETWORK_NO_FIXED_HOST 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.

    src/lib/http.ts, line 87 const response = await fetch(url, { method: "POST", headers, body });

  • SECRETS_ENV_READ Note

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

    src/index.ts, line 121 const authToken = process.env["GF_MCP_AUTH_TOKEN"];

  • OBFUSCATION_FILE_OVER_READ_CAP Note

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

    src/data/airports.json, line 1 [{"code":"AAA","name":"Anaa Airport","city":"Anaa","country":"PF","lat":-17.3526,"lon":-145.51},{"code":"AAB","name":"Arrabury Airport","city":"Tanbar","country":"AU","lat":-26.696

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.
