Etherscan is a remote MCP server that gives an AI agent 16 tools, among them get_block_by_timestamp, get_contract_abi, get_contract_creation. It answers at https://mcp-keyless.etherscan.io/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 10 September 2026; the last check, on 19 October 2026, succeeded.
Read-only Etherscan V2 blockchain data: balances, transactions, transfers, tokens, contracts, logs.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
get_block_by_timestamp | Get the block number closest to a given Unix timestamp (seconds). Inputs: timestamp, closest, chainid |
get_contract_abi | Get the verified ABI (JSON) for a contract address. Inputs: address, chainid |
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. Inputs: contractaddresses, include_creation_bytecode, chainid |
get_contract_source | Get the verified source code and metadata for a contract address. Inputs: address, chainid |
get_gas_oracle | Get current gas price recommendations (safe / propose / fast) from the gas tracker. Inputs: chainid |
get_internal_transactions | Get internal transactions for an address, or by a specific parent transaction hash. Inputs: address, txhash, chainid, startblock, endblock, page |
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' Inputs: address, fromblock, toblock, topic0, topic1, topic2 |
get_native_balance | Get the native coin (e.g. ETH) balance of an address, in wei. Inputs: address, chainid, tag |
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-li |
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). Inputs: standard, address, contractaddress, chainid, startblock, endblock |
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. Inputs: txhash, chainid |
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 sti Inputs: txhash, chainid |
get_transaction_receipt_status | Get the receipt status of a transaction (1 = success, 0 = failed). Post-Byzantium only. Inputs: txhash, chainid |
get_transaction_status | Get the contract execution status of a transaction (detects failed/erroring executions). Inputs: txhash, chainid |
get_transactions | Get the list of normal (external) transactions for an address. Inputs: address, chainid, startblock, endblock, page, offset |
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, o Inputs: view, title, subtitle, chain, metrics, items |

It answered our last check on 19 October 2026 in 484 ms. Over 6 checks since 10 September 2026 it answered 6. Status here comes from Neuronto's own probes, not from the publisher.
Yes. It is published by etherscan.io and served from mcp-keyless.etherscan.io, the vendor's own domain: https://mcp-keyless.etherscan.io/mcp.
16, as returned by the server's own tools/list on 12 September 2026: get_block_by_timestamp, get_contract_abi, get_contract_creation, get_contract_source, get_gas_oracle, get_internal_transactions, get_logs, get_native_balance, and 8 more.

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://mcp-keyless.etherscan.io/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
Publisher: io.etherscan. Endpoint host: mcp-keyless.etherscan.io. ARD identifier: urn:air:io.etherscan:mcp:etherscan-mcp.
First indexed 10 September 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
