Overview

AI-generated overview

Avalara's remote MCP server that lets an assistant classify products with HS codes and check tariff and trade compliance data for cross-border shipments.

What you can do
Classify products with Harmonized System (HS) codes for import and export, including managed classification requests and AI-assisted classification of goods descriptions or documents, then validate and verify the resulting codes against Avalara's trade content. Look up enriched trade compliance content and tariff data for cross-border transactions, and retrieve guidance on classification and compliance from Avalara's documentation.
When to use it
Use it when an assistant needs to assign or check HS codes for goods crossing borders, or to pull tariff and trade compliance information for import and export work. It suits teams already using Avalara for tax and trade compliance who want classification inside an AI client.
Requirements
A remote streamable HTTP endpoint at Avalara's MCP host; no local package. An active Avalara subscription and account, an MCP-compatible client, and a modern web browser to complete the OAuth 2.1 sign-in and consent flow. Internet access is required.
Before you install
Access is granted through OAuth consent to your Avalara account, so review the permissions requested before granting them. Classification and compliance results come from a third party and should be checked before filing or shipping decisions. Requests are subject to rate limits, and connection or permission errors may indicate account access problems.

Installation

In SourceWeft

  1. Open Avalara Classification in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.avalara%2Fclassification/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.
