Grades are a hygiene check, not a security guarantee.

MCP, MCP server

io.github.Digital-Defiance/mcp-filesystem

We've built the most comprehensive suite of MCP servers that give AI agents superpowers they've never had before. This isn't just another tool collection, it's a paradigm shift that transforms AI assistants from code generators into intelligent development partners with run

Grade B

Minor issues only, no Medium or High. Worth a quick look at the findings below before installing.

Graded by PlugVetRubric v2

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

Rescanned at commit 1baa41acbacc, unchanged since the check below.

PERMISSION_DELETE_FILES NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_HOST SECRETS_PATH_DOTENV INSTALL_DOCUMENTED_INSTALLER SECRETS_ENV_READ OBFUSCATION_FILE_OVER_READ_CAP

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    scripts/build-binaries.test.ts, line 23 fs.rmSync(tempDir, { recursive: true, force: true });

  • NETWORK_NO_FIXED_HOST Low

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

    get-docker.sh, line 37 # $ curl -fsSL https://get.docker.com -o install-docker.sh

  • NETWORK_UNNAMED_HOST Low

    Calls a fixed host that the description does not name.

    get-docker.sh, line 37 # $ curl -fsSL https://get.docker.com -o install-docker.sh

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    .gitignore, line 29 .env

  • INSTALL_DOCUMENTED_INSTALLER Note

    Documentation shows an installer that pipes a download into a shell.

    INSTALLATION.md, line 34 curl -fsSL https://raw.githubusercontent.com/digital-defiance/ai-capabilities-suite/main/scripts/install-linux.sh | bash

  • SECRETS_ENV_READ Note

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

    scripts/release-lib/git-operations.js, line 200 return !!(process.env.GITHUB_TOKEN || process.env.GH_TOKEN);

  • OBFUSCATION_FILE_OVER_READ_CAP Note

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

    eng.traineddata, line 1 ���������������������������������������������������������������������������������������������������������������������������������������������\%O�7O

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.
