## Tools
- gas_get_current_price - Use this when you need current gas prices before submitting a transaction. Returns gas tiers and USD cost estimates in JSON.

1. slow: gas price in gwei for slow confirmation (~5 min)
2. standard: gas price in gwei for standard confirmation (~2 min)
3. fast: gas price in gwei for fast confirmation (~30s)
4. instant: gas price in gwei for instant confirmation
5. transferCostUsd: estimated USD cost for a simple ETH transfer
6. swapCostUsd: estimated USD cost for a token swap
7. congestion: network congestion level (low/medium/high)

Example output: {"slow":0.008,"standard":0.012,"fast":0.018,"instant":0.025,"transferCostUsd":0.02,"swapCostUsd":0.05,"congestion":"low","chain":"base"}

Use this BEFORE submitting any on-chain transaction to pick the right gas tier. Essential for timing transactions and avoiding high-gas periods.

Do NOT use for swap quotes -- use dex_get_swap_quote instead. Do NOT use for wallet balance -- use wallet_get_portfolio instead. Do NOT use for multi-chain gas comparison -- use crypto_estimate_gas instead. Endpoint: https://gas-oracle.api.klymax402.com/mcp
