Grades are a hygiene check, not a security guarantee.

MCP, MCP server

Bilinc

Bilinc, an MCP server listed in the PlugVet directory.

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 SECRETS_PATH_DOTENV SECRETS_ENV_READ

Why this grade

  • PERMISSION_DELETE_FILES Low

    Contains a call that can delete files.

    benchmarks/modal/amb_graph_candidate_runner.py, line 123 process = subprocess.run(command, cwd="/opt/amb", capture_output=True, text=True, check=False)

  • NETWORK_NO_FIXED_HOST Low

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

    scripts/prewarm_pg_tenants.py, line 30 rows = await conn.fetch(

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    benchmarks/modal/amb_graph_candidate_runner.py, line 48 if name.startswith(".env") or name.endswith((".sqlite", ".sqlite3", ".db", ".pem", ".key")):

  • SECRETS_ENV_READ Note

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

    src/bilinc/client.py, line 525 self.api_key = os.environ.get("BILINC_API_KEY") or load_config_api_key()

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.
