From the repository
Add the server to your MCP client configuration (e.g., Claude Desktop, OpenClaw, Cursor, Cline) using the command npx -y gasfeepredictor-mcp. Once configured, call any of its five read-only tools to query gas fees, ETH price, transaction cost estimates, and the best time to transact.
get_current_gas
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_gas
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_price
Get the current ETH/USD spot price and its 24-hour change.
best_time_to_transact
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_cost
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.

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. ## Install Add to your MCP client config: { "mcpServers": { "gasfeepredictor": { "command": "npx", "args": ["-y", "gasfeepredictor-mcp"] } } } Read-only, unauthenticated, MIT licensed.Sign in to leave a review
