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.

Rescanned at commit 8cea962148c7, unchanged since the check below.

INSTALL_UNPINNED NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV PERMISSION_SHELL_DECLARED SECRETS_ENV_READ

Why this grade

  • INSTALL_UNPINNED Low

    Dependencies use a range or git URL with no lockfile.

    requirements.txt, line 7 mcp>=1.0

  • NETWORK_NO_FIXED_HOST Low

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

    run_demo.py, line 52 if httpx.get(f"{BASE}/health", timeout=2).status_code == 200:

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    ap2_settle.py, line 18 Reads Solana keypairs from .env (NEVER echoes private keys). Devnet only.

  • PERMISSION_SHELL_DECLARED Note

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

    router/wallet.py, line 29 proc = subprocess.run(args, capture_output=True, text=True, cwd=str(WORKER), timeout=120)

  • SECRETS_ENV_READ Note

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

    arbitrum_settle.py, line 140 buyer_key = os.environ.get("APV0_BUYER_PRIVATE_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.

What was checked

Plain notes from the hygiene checks.

  • Permissions

    Note

    requests shell access. The manifest names this permission.

    PERMISSION_SHELL_DECLARED

    router/wallet.py, line 29

    proc = subprocess.run(args, capture_output=True, text=True, cwd=str(WORKER), timeout=120)

  • Install and update

    Concern

    dependencies are not pinned.

    INSTALL_UNPINNED

    requirements.txt, line 7

    mcp>=1.0

  • Network

    Concern

    can reach a host that is not written as a fixed address.

    NETWORK_NO_FIXED_HOST

    run_demo.py, line 52

    if httpx.get(f"{BASE}/health", timeout=2).status_code == 200:

    run_live.py, line 49

    if httpx.get(f"{BASE}/health", timeout=2).status_code == 200:

    run_mpp_live.py, line 114

    if httpx.get(f"{BASE}/health", timeout=2).status_code == 200:

    Show more

    run_mpp_live.py, line 153

    r = httpx.get(f"{BASE}/work", timeout=10)

    run_v1_dogfood.py, line 50

    if httpx.get(f"{BASE}/health", timeout=2).status_code == 200:

    setup_tempo.py, line 106

    r = httpx.post(FAUCET_URL, json={"address": addr}, timeout=30)

    mcp_router/discovery.py, line 9

    The parse step (`parse_accepts`) is split from the network fetch (`discover_rails`) so

    mcp_router/discovery.py, line 51

    r = httpx.get(url, timeout=timeout, follow_redirects=True)

  • Secrets

    Concern

    reads a credential or environment file.

    SECRETS_ENV_READ SECRETS_PATH_DOTENV

    ap2_settle.py, line 18

    Reads Solana keypairs from .env (NEVER echoes private keys). Devnet only.

    ap2_settle.py, line 33

    ENV = Path(__file__).resolve().parent / ".env"

    arbitrum_settle.py, line 140

    buyer_key = os.environ.get("APV0_BUYER_PRIVATE_KEY", "")

    Show more

    arbitrum_settle.py, line 24

    Reads keys from .env (NEVER echoes private keys). Arbitrum Sepolia testnet only.

    arbitrum_settle.py, line 37

    ENV = Path(__file__).resolve().parent / ".env"

    arbitrum_settle.py, line 138

    sys.exit("APV0_ARB_USDC unset - set the Circle USDC address on Arbitrum Sepolia in .env first "

    arbitrum_settle.py, line 141

    fac_key = os.environ.get("APV0_EVM_FACILITATOR_PRIVATE_KEY", "")

    arbitrum_settle.py, line 144

    sys.exit("need APV0_BUYER_PRIVATE_KEY + APV0_EVM_FACILITATOR_PRIVATE_KEY + APV0_SELLER_ADDRESS in .env "

    gen_evm_facilitator.py, line 9

    Writes APV0_EVM_FACILITATOR_PRIVATE_KEY into .env (gitignored, runtime-only) iff not already

    gen_evm_facilitator.py, line 21

    ENV = Path(__file__).resolve().parent / ".env"

    router/config.py, line 88

    BUYER_PRIVATE_KEY = os.environ.get("APV0_BUYER_PRIVATE_KEY", "") # 0x... testnet key

    router/config.py, line 97

    OPENROUTER_KEY = os.environ.get("APV0_OPENROUTER_KEY", "")

    router/rails/mpp_rail.py, line 226

    self._secret_key = secret_key or os.environ.get("MPP_SECRET_KEY")
