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

Rescanned at commit 755d1612bb43, unchanged since the check below.

PERMISSION_DELETE_FILES SECRETS_PATH_DOTENV OBFUSCATION_ENCODED_BLOB

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    src/ohm_mcp/refactoring/automated_executor.py, line 98 os.remove(filepath)

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    src/ohm_mcp/refactoring/symbol_renamer.py, line 1781 skip_dirs = {'.git', '__pycache__', 'venv', '.venv', 'env', '.env',

  • OBFUSCATION_ENCODED_BLOB Low

    Contains a long base64 shaped string in a file that should be readable.

    README.md, line 11 [![MCP Registry](https://img.shields.io/badge/MCP_Registry-Official-blue?logo=data:image/svg+xml;base64,PHN2ZyB3aWR0aD0iMjQiIGhlaWdodD0iMjQiIHZpZXdCb3g9IjAgMCAyNCAyNCIgZmlsbD0ibm9u

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.
