Scored across 23 tools
Most tools have clearly distinct resource/action targets, especially the base_* read tools. Minor overlaps exist between base_token and base_contract, base_tx and base_receipt, and base_token_risk and its trial variant, but descriptions make the intended use clear. The unrelated audit, scoring, and invoice tools are also distinguishable, though they broaden the server beyond its stated onchain scope.
All tools use consistent snake_case, and the base_* prefix cleanly groups the onchain data tools. Other namespaces (audit_*, score_*, triage_*) are clearly separated and still follow a predictable verb/domain naming style.
23 tools is on the heavy side for a server focused on Base onchain data and token risk. While many base_* tools earn their place, the inclusion of unrelated business/audit tools makes the set feel broader and more inflated than necessary.
The Base read-only surface is strong: balances, allowances, contracts, tokens, prices, risk, NFTs, transfers, transactions, gas, calls, and portfolio coverage are present. Minor gaps remain around generic log/event querying and write/submit operations, but the stated onchain data and risk purpose is largely covered.
