Live Ethereum and L2 gas fees for AI agents: current gas, cheapest L2, ETH price, cost estimates.
Live Ethereum and L2 gas fees for AI agents: current gas, cheapest L2, ETH price, cost estimates. The gasfeepredictor mcp server wraps that behind the Model Context Protocol, so an assistant can use it through 5 defined tools rather than through you.
Live Ethereum + Layer-2 gas-fee data for AI agents, via the Model Context Protocol. Works with Claude Desktop, OpenClaw, Cursor, Cline, and any other MCP client.
Everything the assistant can do here goes through one of these:
get_current_gas — "What's the Ethereum gas fee right now?" — low/avg/high Gwei, ETH price, send-now-vs-waitget_l2_gas — "Cheapest L2 right now?" — live Arbitrum / Base / Optimism / Polygon feesget_eth_price — Current ETH/USD and 24h changebest_time_to_transact — Send now or wait? Next cheaper window + expected savingsestimate_transaction_cost — USD cost of an ETH transfer / USDC transfer / Uniswap swap / NFT mint (or custom gas), per tierThe server ships on npm as gasfeepredictor-mcp, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.
Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Gasfeepredictor's toolset — get_current_gas, get_l2_gas, get_eth_price and 2 more — is a fair guide to whether it matches your workflow. It is maintained by higherbeing; worth a glance at recent repository activity before you build anything load-bearing on it.
