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

Rescanned at commit ff4c6b9446cf, unchanged since the check below.

NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV PERMISSION_SHELL_DECLARED SECRETS_ENV_READ OBFUSCATION_FILE_OVER_READ_CAP OBFUSCATION_FILE_CAP_REACHED

Why this grade

  • NETWORK_NO_FIXED_HOST Low

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

    examples/jira-oauth/plugins/mxcp_plugin_jira_oauth/plugin.py, line 70 response = requests.get(

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    src/mxcp/sdk/core/config/resolvers/__init__.py, line 9 from .env import EnvResolver

  • PERMISSION_SHELL_DECLARED Note

    Runs shell commands, and the manifest or description says so.

    src/mxcp/server/interfaces/cli/dbt.py, line 223 subprocess.run(cmd, env=env, check=True)

  • SECRETS_ENV_READ Note

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

    src/mxcp/sdk/core/config/resolvers/onepassword.py, line 125 self._original_token = os.environ.get("OP_SERVICE_ACCOUNT_TOKEN")

  • OBFUSCATION_FILE_OVER_READ_CAP Note

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

    uv.lock, line 1 version = 1

  • OBFUSCATION_FILE_CAP_REACHED Note

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

    uv.lock, line 1 version = 1

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.
