Overview

Dutyfinch is a Model Context Protocol server that provides US tariff lookup capabilities, including HTS duty rates, Section 301 China lists, and US–China tariff-cut flags. Any MCP-compatible AI assistant can call Dutyfinch's tools directly during conversations or agent runs to access this tariff data.

The server runs as a remote hosted service at https://dutyfinch.cybermax-tools.workers.dev/mcp?via=mcp-registry. It requires an API Key for authentication and is currently at release v1.0.0. No local installation is needed—connect your MCP client to the endpoint and begin using the tariff lookup tools immediately.

Dutyfinch is categorized as Development on mcp.site and integrates with all MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and others. If you maintain Dutyfinch, claim this listing to verify ownership, receive the Verified badge, and keep information up to date.
