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

NETWORK_NO_FIXED_HOST SECRETS_PATH_UNCONFIRMED

Why this grade

  • NETWORK_NO_FIXED_HOST Low

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

    .smithery/shttp/module.js, line 42 `}var oi=class{constructor(e=jg.stdin,r=jg.stdout){this._stdin=e,this._stdout=r,this._readBuffer=new ni,this._started=!1,this._ondata=n=>{this._readBuffer.append(n),this.processRea

  • SECRETS_PATH_UNCONFIRMED Low

    The Secrets check reports a credential or environment file, but no quoted line shows a recognisable path.

    README.md, line 74 Start a new session and call `discover_services` or `service_health`; both are free. Keep the network on `auto` until a wallet is configured. For Base payments, store `X402_EVM_PRI

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.
