## Quality 91/100 (strong)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-11-25; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 100 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 16 of 16 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 3,822 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: 3 tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 16, about 3,822 tokens to load them all
- tool set hash: 9e5b61ade8ac5034855dad769241b99e
- tools last changed: 2026-10-12T14:21:17.244Z
- badge: [![protogrid quality](https://protogrid.dev/badge/io.etherscan/etherscan-mcp.svg)](https://protogrid.dev/servers/io.etherscan/etherscan-mcp)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Packages

_none_

## Tools (16)

- `get_block_by_timestamp`: Get the block number closest to a given Unix timestamp (seconds).
- `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_contract_source`: Get the verified source code and metadata for a contract address.
- `get_gas_oracle`: Get current gas price recommendations (safe / propose / fast) from the gas tracker.
- `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. Adjacent-topic operators (and/or) combine multiple topic filters. Provide 'address' and/or at least one topic.
- `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, 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.
- `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).
- `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.
- `get_transaction_receipt_status`: Get the receipt status of a transaction (1 = success, 0 = failed). Post-Byzantium only.
- `get_transactions`: Get the list of normal (external) transactions for an address.
- `get_transaction_status`: Get the contract execution status of a transaction (detects failed/erroring executions).
- `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.
