Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| get_current_gasA | Get the current Ethereum mainnet gas price (low / average / high, in Gwei) plus the live ETH/USD price and a send-now-vs-wait recommendation. Use this to answer "what is the gas fee right now". |
| get_l2_gasA | Compare live Layer-2 gas fees across Arbitrum, Base, Optimism, and Polygon (Gwei and the estimated wallet fee in USD for a standard transfer), and identify the cheapest right now. Use for "cheapest L2" / "L2 gas fees" questions. |
| get_eth_priceA | Get the current ETH/USD spot price and its 24-hour change. |
| best_time_to_transactA | Find out whether to send a transaction now or wait — returns the current recommendation, expected savings, and when the next cheaper gas window is predicted. |
| estimate_transaction_costA | Estimate the current USD gas cost of a specific Ethereum mainnet action (ETH transfer, ERC-20/USDC transfer, Uniswap swap, or NFT mint), or a custom gas-units amount, at the chosen priority tier. |

Scored across 5 tools
Each tool targets a distinct aspect of gas fees: timing advice, cost estimation for specific actions, current gas prices, ETH price, and L2 comparison. There is no overlapping functionality.
All tool names follow a consistent snake_case pattern with clear verb_noun structures (e.g., get_current_gas, estimate_transaction_cost, best_time_to_transact).
With 5 tools, the server is well-scoped for its purpose of gas fee prediction. It covers all essential queries without being overly minimal or bloated.
The tools cover current gas, cost estimation, timing, ETH price, and L2 comparison. Missing historical gas data or support for non-Ethereum L1s, but covers the core domain well.
