Est-ce que com.mcpscores/onchain-toolkit est sûr ?

Au dernier audit MCP Hub, le serveur MCP « com.mcpscores/onchain-toolkit » est classé « Non encore testé ». Référencé dans l'annuaire. Seul le pentest comportemental fait foi, et il n'a pas encore été exécuté sur ce serveur. Le verdict est réévalué en continu ; consultez la fiche pour l'état à jour.

Méthode : MCP Hub analyse la description de chaque outil (couche 1) et, pour le verdict fort, exécute le serveur dans une micro-VM isolée avec leurres et réseau bloqué (couche 2). On publie des noms et des compteurs, jamais le contenu brut renvoyé par un outil.

Les 6 outils

• address_info≈ 253 tokens

  Native balance, the next nonce to use, and whether the address holds contract code — the three things needed before sending from or to an address. Pass 'token' as well to read an ERC-20 balance for the same address in the same call. Values are read at the latest block, so a reorg can change them. Costs $0.008 USDC per call via x402 on Base.

  Paramètres, retour & exemple (3)

  Paramètres

  • chain · string · optionnel
    ethereum, base, arbitrum, optimism or polygon. Defaults to base.
  • token · string · optionnel
    Optional ERC-20 contract address to also report that token's balance.
  • address · string · requis
    0x-prefixed 20-byte address.

  Exemple d'appel

  {"name": "address_info", "arguments": {"address": "texte"}}

  Exemple de retour

  {"content": [{"type": "text", "text": "…"}]}

• demand_report≈ 108 tokens

  FREE, no payment. The aggregate of what agents have told us they are looking for, most-requested first, with the categories nothing available yet serves.

  Paramètres

  • days · string · optionnel
    Window in days, default 30, max 90.

  Exemple d'appel

  {"name": "demand_report", "arguments": {"days": "texte"}}

  Exemple de retour

  {"content": [{"type": "text", "text": "…"}]}

• gas_now≈ 198 tokens

  Live gas price on Ethereum, Base, Arbitrum, Optimism or Polygon — in wei and gwei, plus what a plain 21,000-gas transfer would cost in the native token, which is the number you actually budget with. Pass several chains comma-separated to compare where to execute. Call this immediately before sending a transaction: gas moves every block, so the answer is good for seconds, not minutes. Costs $0.005 USDC per call via x402 on Base.

  Paramètres, retour & exemple (1)

  Paramètres

  • chain · string · optionnel
    One or more of ethereum, base, arbitrum, optimism, polygon — comma-separated, e.g. 'base,ethereum'. Defaults to base.

  Exemple d'appel

  {"name": "gas_now", "arguments": {"chain": "texte"}}

  Exemple de retour

  {"content": [{"type": "text", "text": "…"}]}

• request_data≈ 165 tokens

  FREE, no payment. Describe in your own words the data you are trying to buy — anything, not just on-chain data — and get back whether we operate a service that supplies it, with the MCP endpoint if so. Every request is catalogued so repeatedly-requested data gets built. Nothing identifying is stored, only the words of the request.

  Paramètres, retour & exemple (1)

  Paramètres

  • need · string · requis
    What you are looking for.

  Exemple d'appel

  {"name": "request_data", "arguments": {"need": "texte"}}

  Exemple de retour

  {"content": [{"type": "text", "text": "…"}]}

• token_info≈ 230 tokens

  Read an ERC-20's name, symbol, decimals and total supply straight from the contract on the chain you name, and confirm the address actually has code there. Use before quoting an amount or building a transfer: getting decimals wrong is the classic way to send 1,000,000x the intended value. An address with no code, or a contract that is not an ERC-20, is reported as such and is NOT charged. Costs $0.005 USDC per call via x402 on Base.

  Paramètres, retour & exemple (2)

  Paramètres

  • chain · string · optionnel
    ethereum, base, arbitrum, optimism or polygon. Defaults to base.
  • address · string · requis
    0x-prefixed 20-byte contract address.

  {"name": "token_info", "arguments": {"address": "texte"}}

  Exemple de retour

  {"content": [{"type": "text", "text": "…"}]}

• tx_status≈ 216 tokens

  Status of a transaction by hash: success, failed or still pending, with the block it landed in, sender and recipient, value moved, gas used, the fee actually paid, and how many logs it emitted. Use to confirm an action you took really settled rather than assuming it did. An unknown hash is reported as not_found and is NOT charged. Costs $0.005 USDC per call via x402 on Base.

  Paramètres, retour & exemple (2)

  Paramètres

  • hash · string · requis
    0x-prefixed 32-byte transaction hash.
  • chain · string · optionnel
    ethereum, base, arbitrum, optimism or polygon. Defaults to base.

  Exemple d'appel

  {"name": "tx_status", "arguments": {"hash": "texte"}}
