Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 724 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-11-25, serverInfo.name etherscan-mcp.

  • Pass
    Lists tools

    tools/list returned 17 tools.

  • Pass
    Current protocol

    Negotiated 2025-11-25. The bar is 2025-06-18 or newer.

  • Pass
    HTTPS

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 724 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 724 ms over 1 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

  • Not measured
    Free tier cited

    No publisher quote has been checked.

Tools

  • Pass
    Tools described

    Every tool description is at least 20 characters.

  • Pass
    Valid input schemas

    Every inputSchema is a JSON Schema object.

  • Pass
    Parameters documented

    61 of 74 parameters have a description (82%). The bar is 80%.

  • Pass
    Safety hints

    Every tool sets readOnlyHint or destructiveHint.

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

  • Fail
    Website matches publisher

    The website host does not match the reverse-domain namespace.

  • Fail
    Source repo linked

    No repository URL is on file.

  • Not measured
    Repo owner matches

    This namespace is not an io.github login, so the owner comparison does not apply.

  • Pass
    Recently updated

    Updated 2026-09-04T06:33:47.776955Z, within 180 days.

Capabilities

Tools 17

get_block_by_timestamp

Get the block number closest to a given Unix timestamp (seconds).

Discovered
get_contract_abi

Get the verified ABI (JSON) for a contract address.

Discovered
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.

Discovered
get_contract_source

Get the verified source code and metadata for a contract address.

Discovered
get_gas_oracle

Get current gas price recommendations (safe / propose / fast) from the gas tracker.

Discovered
get_internal_transactions

Get internal transactions for an address, or by a specific parent transaction hash.

Discovered
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.

Discovered
get_native_balance

Get the native coin (e.g. ETH) balance of an address, in wei.

Discovered
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 proof that it lacks live support.

Discovered
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).

Discovered
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.

Discovered
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.

Discovered
get_transaction_receipt_status

Get the receipt status of a transaction (1 = success, 0 = failed). Post-Byzantium only.

Discovered
get_transaction_status

Get the contract execution status of a transaction (detects failed/erroring executions).

Discovered
get_transactions

Get the list of normal (external) transactions for an address.

Discovered
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.

Discovered
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. A name that does not resolve returns ok:true with a null result.
