Grades are a hygiene check, not a security guarantee.

MCP, MCP server

Xrm Mcp

A minimal MCP server that gives AI coding agents (Claude Code, GitHub Copilot, Codex CLI, Cursor, Gemini CLI) clean read + careful write access to Microsoft Dataverse / XRM environments via the Dataverse Web API v9.2.

Compatibility: Not stated.

Grade B

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

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

Rescanned at commit acab4aa296b6, unchanged since the check below.

NETWORK_NO_FIXED_HOST SECRETS_PATH_UNCONFIRMED PERMISSION_SHELL_DECLARED

Why this grade

  • NETWORK_NO_FIXED_HOST Low

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

    src/xrm_mcp/api.py, line 11 def fetch(org_url: str, path: str, token: str, params: dict[str, Any] | None = None) -> dict:

  • SECRETS_PATH_UNCONFIRMED Low

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

    .gitignore, line 105 # Environments

  • PERMISSION_SHELL_DECLARED Note

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

    src/xrm_mcp/auth.py, line 50 result = subprocess.run(cmd, capture_output=True, text=True, timeout=10, env=_AZ_CLI_ENV)

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.

  • Install and update

    Pass

    No install-time script found, and dependencies are pinned or absent.

  • Network

    Concern

    can reach a host that is not written as a fixed address.

    NETWORK_NO_FIXED_HOST
