Grades are a hygiene check, not a security guarantee.

MCP, MCP server

Vsql Mcp

vsql_mcp exposes a VillageSQL database as a Model Context Protocol server, so MCP clients — Claude Code, Claude Desktop, IDE agents — can discover the schema and run governed queries without a sidecar process.

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.

NETWORK_NO_FIXED_HOST PERMISSION_SHELL_DECLARED

Why this grade

  • NETWORK_NO_FIXED_HOST Low

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

    mysql-test/t/mcp_basic.test, line 67 with urllib.request.urlopen(req) as r:

  • PERMISSION_SHELL_DECLARED Note

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

    mysql-test/t/mcp_concurrency.test, line 89 subprocess.Popen([sys.executable, "-B", os.path.abspath(__file__),

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.
