## Tools

16 declared. Observed from a live `tools/list` probe.
- `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 
- `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 respons
- `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, refreshe
- `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_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
- `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

## Install

**Verdict: review** — Installable, but 2 things to check first: No CVE coverage: this entry has no npm/PyPI coordinates to query OSV against, so "no known vulnerabilities" is not a claim that can be made about it.
**Cautions** (coverage gaps and advisories — never blocking)
- No CVE coverage: this entry has no npm/PyPI coordinates to query OSV against, so "no known vulnerabilities" is not a claim that can be made about it.
- No publisher has proved control of this listing; it is indexed, not vouched for.
**Config** (claude-code):
```json
"{\n  \"mcpServers\": {\n    \"etherscan-mcp\": {\n      \"type\": \"http\",\n      \"url\": \"https://mcp-keyless.etherscan.io/mcp\"\n    }\n  }\n}"
```

## Blast radius

Contained to moderate — no credential declaration found, from the publisher, the upstream registry, or the README. Known so far: runs on someone else's infrastructure; read-only tool surface.
- Floor 9, ceiling 27 (tier: unknown)
- `unknown` means the floor and ceiling land in different bands — not measured enough to name one. It does not mean low.
- This is impact, not likelihood. A high radius is not a defect: a filesystem server is supposed to write files. It is never part of the trust score.
