Est-ce que money.barker/stablecoin-yield est sûr ?

Au dernier audit MCP Hub, le serveur MCP « money.barker/stablecoin-yield » 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.

• barker_executable_pools≈ 359 tokens

  EXECUTION DISCOVERY: which stablecoin vaults in Barker's index support direct deposit/redeem through barker_execution_quote. Returns executable pools with adapter support, live deposit capacity (is_full) and APY/TVL. Call this before barker_execution_quote — every pool listed here can be quoted, and its pool_uid is the exact string that tool expects (its vault_token_address works there too). Skip this call entirely if you already know the vault contract address. All parameters are optional: call with no arguments to get the top executable pools across every asset. APY unit: decimal (0.05 = 5%). Use for 'which pools can my agent actually deposit into', '哪些池子能直接存'. (paid: $0.01 per call via x402)

• barker_execution_quote≈ 716 tokens

  EXECUTION QUOTE (non-custodial): buy an unsigned, ready-to-sign transaction that deposits into or redeems from a stablecoin vault. Returns transaction_request {chainId,from,to,data,value} + route + risk summary + approval info. Barker NEVER broadcasts and never holds funds — return the transaction to YOUR user's wallet to sign; vault shares always go to signer_address (receiver is not a parameter). Same-chain only (self/portals adapters). pool_uid takes EITHER a Barker pool_uid OR the vault contract address — if you already know the vault address, quote directly, no discovery call needed. Flow: barker_yield_advisor → barker_executable_pools → this tool → your user signs. Asset identity is resolved by the selected pool; symbols and underlying-asset token addresses are never accepted as identity (pass the VAULT contract, not the asset contract). If a pool has multiple possible underlying assets, the backend rejects ambiguity instead of guessing. Use for 'deposit 1000 USDC into this vault', '帮我把 USDC 存进这个池子（自己签名）'. (paid: $0.05 per call via x402)

  Paramètres, retour & exemple (7)

  Paramètres

  • action · string · optionnel · deposit | redeem
    Default deposit
  • amount · string · optionnel
    Same amount in human units ("1000" = 1000 USDC), converted server-side using the pool's own asset decimals. Use this if you don't want to compute base units yourself. Alternative to amount_base_units.
  • chain_id · integer · optionnel
    Optional, only useful when pool_uid is a contract address that is deployed at the same address on several chains (e.g. Aave aTokens). EVM chain id, e.g. 8453 for Base.
  • pool_uid · string · requis
    Either the exact pool_uid from barker_executable_pools (copy verbatim), OR the vault contract address (0x + 40 hex) if that is what you already have — no discovery call needed. Both are matched exactly; partial names and keywords are rejected (POOL_NOT_FOUND), because this is a money path and Barker never guesses the pool. If one contract hosts several products (e.g. Pendle PT vs LP), you get 409 POOL_AMBIGUOUS with the exact candidates to choose from.
  • slippage · number · optionnel
    Optional slippage tolerance, e.g. 0.005
  • signer_address · string · requis
    EVM address that will sign AND receive vault shares / redeemed assets. Mandatory — it is the tx sender and the share recipient, so Barker can never infer or default it.
  • amount_base_units · string · requis
    Integer amount in token base units (1 USDC = 1000000). For redeem: underlying assets to withdraw. Send either this OR `amount` — not both (they are cross-checked and a mismatch is rejected).

  VAULT POSITION (on-chain read): current redeemable value of a wallet's ERC-4626 vault position. Pass the pool_uid (from barker_executable_pools / barker_execution_quote) and the wallet address; Barker resolves the vault contract and reads balanceOf + convertToAssets directly on-chain, returning shares and current_value in the vault's underlying asset (value_asset, e.g. USDC). Barker does not store your deposit baseline — record the principal you deposited yourself; earned = current_value - your net deposits. Use after depositing via barker_execution_quote to monitor a position: 'how much is my vault position worth now', '我存进金库的 USDC 现在值多少'. (paid: $0.001 per call via x402)
