    Mentions a .env file.

    CHANGELOG.md, line 1433 ProgIDs in `.env.example` are commented out and marked UNVERIFIED: none has

  • SECRETS_ENV_READ Note

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

    config.py, line 102 self.mcp_auth_token: str = os.environ.get("MCP_AUTH_TOKEN", "").strip()

  • OBFUSCATION_FILE_OVER_READ_CAP Note

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

    server.py, line 1 """AutoCAD MCP Pro - FastMCP 3.0 server.

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.
