TDQS
Scored across 6 tools
Each tool targets a distinct Ethereum data type (balance, ABI, ENS, gas prices, token transfers, transactions) with no overlap, making it easy for an agent to choose the correct one.
All tools follow a verb_noun pattern with 'get' as the verb except 'check-balance' uses 'check', which is a minor inconsistency but still predictable.
6 tools is well-scoped for an Etherscan server, covering the most common Ethereum queries without being overwhelming or too sparse.
The set covers core Ethereum operations (balance, transactions, ABI, ENS, gas, token transfers), but lacks some common endpoints like block queries or event logs, which are minor gaps.
