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

Rescanned at commit c534b9c4b558.

PERMISSION_DELETE_FILES NETWORK_NO_FIXED_HOST SECRETS_PATH_UNCONFIRMED OBFUSCATION_FILE_OVER_READ_CAP

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    custom_components/mcp_server_http_transport/tools/appdaemon_files.py, line 757 fs.unlink(rel)

  • NETWORK_NO_FIXED_HOST Low

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

    custom_components/mcp_server_http_transport/tools/traces.py, line 286 "Specific run to fetch (from list_traces). Omit for the most recent run."

  • SECRETS_PATH_UNCONFIRMED Low

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

    .gitignore, line 48 # Environments

  • OBFUSCATION_FILE_OVER_READ_CAP Note

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

    poetry.lock, line 1 # This file is automatically @generated by Poetry 2.4.1 and should not be changed by hand.

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.
