上下文成本
這是每次將伺服器的工具載入模型上下文時所消耗的約略 token 數量。數量越高，可用於其他工作的注意力就越少。

⚪scan_contract(chainId, address)
Security scan of a verified EVM smart contract: who controls it now (owner / proxy admin: renounced, single-key EOA or Safe multisig), every owner/role-gated function (mint, pause, blacklist, upgrade, fees), proxy status, and Slither static-analysis findings ranked by impact. Use before approving, depositing into or buying a token. Chains: 1 Ethereum, 8453 Base, 42161 Arbitrum, 10 Optimism, 137 Polygon, 56 BNB.

}🟢check_token(chainId, address)
Fast (1-3 s) risk verdict for an ERC-20 token before buying it: LOW/MEDIUM/HIGH with reasons. Who controls it (renounced, single key, Safe multisig, timelock), upgradeable proxy, admin powers in the bytecode (mint, blacklist, pause, adjustable tax, trading switch), source verification, DEX liquidity and pair age. Chains: 1 Ethereum, 8453 Base, 42161 Arbitrum, 10 Optimism, 137 Polygon, 56 BNB.

}⚪gas_now(chainId)
Live EIP-1559 gas for a chain: base fee, slow/standard/fast tips, maxFeePerGas values and the cost of common actions. Chains: 1, 8453, 42161, 10, 137, 56.

}⚪address_info(chainId, address)
What is this address? EOA, EIP-7702 delegated EOA, Safe multisig (threshold, owners), timelock, ERC-20 token, proxy or contract, with native balance. Use before sending funds to or trusting an address.

}🟢check_x402_payability(url)
For x402 sellers: can a real buyer actually pay this endpoint? Sends one payment signed by a fresh unfunded key through the endpoint's server and facilitator. Payable endpoints fail only on balance; anything else is reported with the exact reason (schema, description over 500 chars, EIP-712 domain, price over the $1 default client cap, paywall not enforcing).
