Wazuh Mcp Server

Wazuh Mcp Server, an MCP server listed in the PlugVet directory.

Compatibility: Not stated.

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 e751871c850d, unchanged since the check below.

INSTALL_UNPINNED NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_HOST SECRETS_PATH_DOTENV PERMISSION_SHELL_DECLARED SECRETS_ENV_READ OBFUSCATION_FILE_OVER_READ_CAP

Why this grade

  • INSTALL_UNPINNED Low

    Dependencies use a range or git URL with no lockfile.

    requirements.txt, line 10 fastapi>=0.128.0,<1.0.0

  • NETWORK_NO_FIXED_HOST Low

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

    deploy-production.sh, line 147 if curl -f -s http://localhost:3000/health > /dev/null 2>&1; then

  • NETWORK_UNNAMED_HOST Low

    Calls a fixed host that the description does not name.

    deploy-production.sh, line 147 if curl -f -s http://localhost:3000/health > /dev/null 2>&1; then

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    deploy-production.sh, line 3 # generated key to the server (which reads MCP_API_KEY from .env).

  • PERMISSION_SHELL_DECLARED Note

    Runs shell commands, and the manifest or description says so.

    deploy.py, line 70 result = subprocess.run(cmd, capture_output=True, text=True, check=check)

  • SECRETS_ENV_READ Note

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

    evals/tool_selection.py, line 190 p.add_argument("--api-key", default=os.getenv("OPENAI_API_KEY"))

  • OBFUSCATION_FILE_OVER_READ_CAP Note

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

    src/wazuh_mcp_server/server.py, line 1 #!/usr/bin/env python3

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.

What was checked

Plain notes from the hygiene checks.

  • Permissions

    Note

    requests shell access. The manifest names this permission.

  • Install and update

    Concern

    dependencies are not pinned.

    INSTALL_UNPINNED

    requirements.txt, line 10

    fastapi>=0.128.0,<1.0.0

  • Network

    Concern

    can reach a host that is not written as a fixed address. can reach download.docker.com. The description does not name that host. can reach raw.githubusercontent.com. The description does not name that host.
