Journey fit
Fee logic belongs in integration work while you build transaction flows and agent-assisted signing prep, before Ship hardening. Gas and fee endpoints are third-party API integrations—placed under build.integrations alongside other CryptoAPIs-io MCP servers.
How it compares
API-backed fee estimation MCP, not a local hardhat gas reporter or wallet browser extension.
