## Tools (as reported by the server, not verified)

- `get\_native\_balance`: Get the native coin \(e.g. ETH\) balance of an address, in wei.
- `get\_transactions`: Get the list of normal \(external\) transactions for an address.
- `get\_internal\_transactions`: Get internal transactions for an address, or by a specific parent transaction hash.
- `get\_token\_transfers`: Get token transfer events for an address, optionally filtered by token contract. Select the token standard: erc20 \(fungible, default\), erc721 \(NFT\), or erc1155 \(multi-token\).
- `resolve\_ens\_name`: Resolve an ENS name \(or onchain subdomain, e.g. etherscan.eth or gm.etherscan.eth\) to its Ethereum address. Ethereum mainnet only. Offchain names that require CCIP Read / wildcard resolution \(e.g. \*.base.eth\) are not supported.
- `get\_contract\_source`: Get the verified source code and metadata for a contract address.
- `get\_contract\_abi`: Get the verified ABI \(JSON\) for a contract address.
- `get\_contract\_creation`: Get the creator address and creation transaction hash for up to 5 contract addresses. The multi-kilobyte creation bytecode is omitted by default to keep responses small; set include\_creation\_bytecode=true to include it.
- `get\_transaction\_receipt\_status`: Get the receipt status of a transaction \(1 = success, 0 = failed\). Post-Byzantium only.
- `get\_transaction\_status`: Get the contract execution status of a transaction \(detects failed/erroring executions\).
- `get\_gas\_oracle`: Get current gas price recommendations \(safe / propose / fast\) from the gas tracker.
- `get\_block\_by\_timestamp`: Get the block number closest to a given Unix timestamp \(seconds\).
- `get\_supported\_chains`: Get the chains / chain IDs supported by the Etherscan V2 API. In the hosted \(proxy\) deployment this returns a bundled snapshot shipped with the server, refreshed when the package is updated; in direct/stdio mode it queries the live chain-list endpoint. A chain's absence from the returned list is not
- `get\_logs`: Search event logs by contract address and/or topics over a block range. Topics are 32-byte hex values; topic0 is usually the keccak256 event-signature hash. Adjacent-topic operators \(and/or\) combine multiple topic filters. Provide 'address' and/or at least one topic.
- `get\_transaction\_by\_hash`: Get the full transaction object for a transaction hash \(from, to, value, input data, gas, gas price, nonce, block number/hash, transaction index\). Returns null if the hash is unknown.
- `get\_transaction\_receipt`: Get the transaction receipt for a transaction hash \(execution status, gas used, cumulative gas used, effective gas price, logs, and the created contract address for deployments\). Returns null if the hash is unknown or the transaction is still pending.
- `render\_etherscan\_widget`: Present exact facts returned by Etherscan data tools in a fast explorer-style card. Call the relevant Etherscan data tool first and copy only supported values into this tool. Never invent scores, risk labels, historical prices, forecasts, or audit conclusions.
