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

PERMISSION_DELETE_FILES INSTALL_UNPINNED NETWORK_NO_FIXED_HOST

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    src/commands/init/backup.test.ts, line 22 await fs.unlink(resolve(testDir, file));

  • INSTALL_UNPINNED Low

    Dependencies use a range or git URL with no lockfile.

    package.json, line 47 @modelcontextprotocol/sdk

  • NETWORK_NO_FIXED_HOST Low

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

    src/mcp-registry/registry-client.ts, line 181 const response = (await fetch(url, {

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.
