Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| wallet_portfolioA | Get a wallet's LIVE multi-chain portfolio in ONE call: native coin balances (ETH/POL) AND top ERC-20 token holdings, each priced in USD, across Ethereum, Base, Polygon, Arbitrum and Optimism. Reads balances straight from public RPCs and joins live prices. Use this whenever you need the current on-chain holdings / net worth of an EVM address without making dozens of RPC calls yourself. |
| token_infoA | Get on-chain facts about a token/contract: symbol, name, decimals, total supply, whether it is a deployed contract, whether it is an EIP-1967 proxy (and its implementation address), and live USD price. Reads directly from the chain. Use to vet or describe a token contract before interacting with it. |
| gas_pricesA | Get LIVE gas prices (base fee, gas price, priority fee, latest block) for one chain or all supported chains at once. Use to decide where/when a transaction is cheapest. |
| token_priceA | Get the live USD price of a token by {chain,address} (most precise) or by coingeckoId or symbol. Free key-less price feed (DefiLlama/CoinGecko). |

Scored across 4 tools
Each tool targets a distinct facet of chain data: gas prices, token metadata, token pricing, and wallet portfolio. Overlap between token_info and token_price is minimal since token_info provides comprehensive on-chain facts while token_price is a focused price lookup.
All tool names follow a consistent snake_case pattern using noun phrases (gas_prices, token_info, token_price, wallet_portfolio). No mixing of styles or inconsistent verbs.
With 4 tools, the server is well-scoped for its purpose of providing on-chain data. Each tool serves a clear need without unnecessary bloat or redundancy.
The tools cover gas, token details, price, and portfolio. Missing features like block info or transaction history are acceptable given the focused scope, but a chain-data server could optionally include additional data points.
