Grades are a hygiene check, not a security guarantee.

MCP, MCP server

UCAI

UCAI, 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.

Rescanned at commit c25ecc5f4002, unchanged since the check below.

NETWORK_NO_FIXED_HOST SECRETS_PATH_DOTENV OBFUSCATION_MINIFIED_PAYLOAD PERMISSION_SHELL_DECLARED SECRETS_ENV_READ

Why this grade

  • NETWORK_NO_FIXED_HOST Low

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

    src/abi_to_mcp/__init__.py, line 137 fetch_result = asyncio.run(registry.fetch(abi_source, network=network))

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    examples/defi_protocol/generate.sh, line 20 echo " echo 'RPC_URL=https://eth.llamarpc.com' > .env"

  • OBFUSCATION_MINIFIED_PAYLOAD Low

    Contains a very long line with almost no spaces in a script or style file.

    docs/site/assets/javascripts/bundle.79ae519e.min.js, line 1 "use strict";(()=>{var Zi=Object.create;var _r=Object.defineProperty;var ea=Object.getOwnPropertyDescriptor;var ta=Object.getOwnPropertyNames,Bt=Object.getOwnPropertySymbols,ra=Obj

  • PERMISSION_SHELL_DECLARED Note

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

    src/abi_to_mcp/cli/commands/serve.py, line 76 process = subprocess.run(

  • SECRETS_ENV_READ Note

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

    src/abi_to_mcp/core/config.py, line 126 self.private_key = os.environ.get("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

    src/abi_to_mcp/cli/commands/serve.py, line 76

    process = subprocess.run(

  • Install and update

    Pass

    No install-time script found, and dependencies are pinned or absent.

  • Network

    Concern

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

    NETWORK_NO_FIXED_HOST

    fetch_result = asyncio.run(registry.fetch(abi_source, network=network))

    async def fetch(self, source: str, **kwargs) -> FetchResult:

    src/abi_to_mcp/fetchers/base.py, line 40

    raise NotImplementedError("Subclasses must implement fetch()")

  • Secrets

    Concern

    reads a credential or environment file.

    private_key = os.environ.get("PRIVATE_KEY")

    web-v2/src/lib/networks.ts, line 82

    const apiKey = process.env.NEXT_PUBLIC_ETHERSCAN_API_KEY || "";

  • Agent instructions

    Pass

    No instruction to ignore earlier instructions or to hide a step.

  • Obfuscation

    Concern

    contains a minified payload.
