## Verdict

Etherscan MCP server answered 99.8% of Glimind's liveness checks over 30 days, better than 24% of MCP servers, with 867 ms median handshake and 5 outages in 90 days. Its agent-readiness grade is A (97/100) across 17 tools, costing an agent about 4,088 tokens to load. Checked every few minutes; no tool is ever called.

- `get_internal_transactions`: Get internal transactions for an address, or by a specific parent transaction hash.
- `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. Adj
- `get_native_balance`: Get the native coin (e.g. ETH) balance of an address, in wei.
- `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, refreshe

- `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 
- `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
- `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_transactions`: Get the list of normal (external) transactions for an address.
- `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 i
- `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 C
