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

PERMISSION_DELETE_FILES NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV SECRETS_ENV_READ

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    src/mcp_server_hubspot/faiss_manager.py, line 163 os.remove(index_path)

  • NETWORK_NO_FIXED_HOST Low

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

    src/mcp_server_hubspot/clients/conversation_client.py, line 282 response = requests.request("GET", url, headers=headers, params=params)

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    src/mcp_server_hubspot/server.py, line 358 # Load environment variables from .env file if it exists

  • SECRETS_ENV_READ Note

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

    src/mcp_server_hubspot/hubspot_client.py, line 62 token = access_token or os.getenv("HUBSPOT_ACCESS_TOKEN")

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.
