Grades are a hygiene check, not a security guarantee.

MCP, MCP server

Attestor

The memory layer for agent teams.

Compatibility: Not stated.

Grade B

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

Graded by PlugVetRubric v2

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

PERMISSION_DELETE_FILES NETWORK_NO_FIXED_HOST NETWORK_UNNAMED_HOST SECRETS_PATH_DOTENV SECRETS_ENV_READ OBFUSCATION_FILE_OVER_READ_CAP OBFUSCATION_FILE_CAP_REACHED

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    attestor/init_wizard.py, line 171 shutil.rmtree(path)

  • NETWORK_NO_FIXED_HOST Low

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

    attestor/client.py, line 54 with urllib.request.urlopen(req, timeout=self.timeout) as resp:

  • NETWORK_UNNAMED_HOST Low

    Calls a fixed host that the description does not name.

    attestor/client.py, line 54 with urllib.request.urlopen(req, timeout=self.timeout) as resp:

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    attestor/init_wizard.py, line 46 `$ENV_VAR` references** (resolved from the environment / `.env`).

  • SECRETS_ENV_READ Note

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

    attestor/api.py, line 73 api_key = os.environ.get("PINECONE_API_KEY")

  • 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 2.3.2 and should not be changed by hand.

  • OBFUSCATION_FILE_CAP_REACHED Note

    The 400 file cap was reached before every file was read.

    poetry.lock, line 1 # This file is automatically @generated by Poetry 2.3.2 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.
