Cross-border duty-rate and Trade & Tariff content lookups with product compliance and restrictions
The publisher's own server: Avalara Tax Content
Overview
Avalara's remote MCP server that lets an assistant look up cross-border duty rates, Trade & Tariff content, and product compliance and restrictions.
- What you can do
- Look up cross-border duty rates for transactions and products, as described for the Cross-Border Trade Services server in the README (the manifest lists no individual tools). Query Trade & Tariff content libraries, including import trade restrictions. Retrieve product compliance and restriction information for cross-border goods. Access Avalara's regularly updated tax and trade content through an OAuth-authorized connection.
- When to use it
- Useful when an assistant needs duty calculations, tariff content, or import restriction and product compliance information for cross-border trade, and the organization already has an Avalara subscription covering these services.
- Requirements
- A remote endpoint at mcp.avalara.com over streamable HTTP. An active Avalara subscription account is required, plus OAuth sign-in and consent through a modern web browser. Internet access is needed.
Installation
In SourceWeft
- Open Avalara Cross-Border in the dashboard and add it to a workspace.
- Connect the required credentials. They are stored privately and never shown on public pages.
- 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%2Fcross-border/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.Other MCP clients
Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.
