Overview

AI-generated overview

Gives an assistant source-linked 2026 US tariff and landed cost facts, including layered duties, MPF and HMF.

What you can do
This remote MCP server supplies reference facts about 2026 US import duties and landed cost calculations. According to its description, it covers layered tariffs plus the Merchandise Processing Fee (MPF) and Harbor Maintenance Fee (HMF), with sources linked to the figures. No individual tools are listed in the available information.
When to use it
Worth adding when an assistant needs to look up or explain US duty components and landed cost inputs for 2026, for example during trade, sourcing, or pricing questions. It is a reference source rather than a calculation or filing system.
Requirements
It is a remote streamable HTTP endpoint, so no local runtime or package installation is needed. The manifest declares no authentication, no environment variables, and no headers, so nothing appears to be required beyond network access to the endpoint.
Before you install
The manifest declares no credentials, so no secrets are requested. Because the server only returns reference facts, verify figures against official customs sources before relying on them for pricing, compliance, or filings; the description does not state how current or complete the data is.

Installation

In SourceWeft

  1. Open GroundTruth: 2026 US Tariff & Landed Cost in the dashboard and add it to a workspace.
  2. 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/site.coze.page.dytsk9wrfv%2Fgroundtruth/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
