US HTS Code Lookup

Overview

US HTS Code Lookup is a Model Context Protocol server that lets you look up, validate, and search US HTS tariff codes offline. Get official text, duty rates, and find the closest matching codes—all without leaving your AI assistant.

The server runs locally on your machine using the hts-lookup Python package, installed via uvx hts-lookup. It communicates with your MCP client over stdio and requires no authentication or external credentials to get started. The latest release is v0.2.0.

You'll find US HTS Code Lookup listed in the Development category on mcp.site. It works with Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and any other MCP-compatible client. If you maintain this server, claim your listing to earn the Verified badge and keep information up to date.
