What does it add to Hermes?
Gas Estimator API is a MCP server related to payments and business operations. It handles financial or commercial data and actions; any write operation needs stronger approval and limits than ordinary use.
This plain-language explanation is based on the publisher description. The original text remains visible for verification.
Do not add it merely to experiment when Hermes already has a simpler path, or when you cannot review its source and permissions and sse transport.
Best for users who understand read versus write access and authentication.
Use a sandbox or test data and do not grant real payment or refund permissions in the first test.
Original publisher description
Multi-chain gas estimation — ETH, Base, Polygon, Arbitrum, BSC. x402 micropayment.
