Gas Fee Predictor MCP Server

Live Ethereum and Layer-2 gas-fee data for AI agents, over the Model Context Protocol. Works with Claude Desktop, OpenClaw, Cursor, Cline, and any MCP client. A thin, read-only wrapper over the free public API at api.gasfeepredictor.com — no key, no auth. Every answer cites gasfeepredictor.com.

Tools

• get_current_gas — current Ethereum gas (low/avg/high Gwei), ETH price, and a send-now-vs-wait call.
• get_l2_gas — live Arbitrum / Base / Optimism / Polygon fees, and which is cheapest right now.
• get_eth_price — current ETH/USD and 24h change.
• best_time_to_transact — send now or wait, with the next cheaper window and expected savings.
• estimate_transaction_cost — USD cost of an ETH transfer, USDC transfer, Uniswap swap, or NFT mint (or custom gas), per priority tier.
