Gateway Tariff MCP

An official MCP server from Gateway Lines that connects AI assistants to their live tariff engine. It provides US import duty calculations, HTS code classification, and trade policy change tracking using data from the US Harmonized Tariff Schedule and Federal Register. The server allows agents to determine landed costs and understand applicable trade actions like Section 301 or 232 duties.

Claude Code

Run this once in a terminal. It registers a Streamable HTTP server. Use --scope project to write .mcp.json for the repo.

Claude Code configuration

claude mcp add --transport http gateway-tariff-mcp https://mcp.gatewaylines.com

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).

Codex configuration

codex mcp add gateway-tariff-mcp --url https://mcp.gatewaylines.com

Cursor

Merge this server into .cursor/mcp.json in your project, then enable gateway-tariff-mcp in your MCP settings.

Cursor configuration

{
  "mcpServers": {
    "gateway-tariff-mcp": {
      "url": "https://mcp.gatewaylines.com"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure). The type must be streamableHttp for a remote HTTP server.

Cline configuration

{
  "mcpServers": {
    "gateway-tariff-mcp": {
      "type": "streamableHttp",
      "url": "https://mcp.gatewaylines.com",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start gateway-tariff-mcp and inspect its tools.

VS Code configuration

{
  "servers": {
    "gateway-tariff-mcp": {
      "type": "http",
      "url": "https://mcp.gatewaylines.com"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.

Gemini CLI configuration

gemini mcp add --transport http gateway-tariff-mcp https://mcp.gatewaylines.com

Claude Desktop

Merge this into claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\), then restart Claude Desktop.

Claude Desktop configuration

{
  "mcpServers": {
    "gateway-tariff-mcp": {
      "url": "https://mcp.gatewaylines.com"
    }
  }
}

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.

Windsurf configuration

{
  "mcpServers": {
    "gateway-tariff-mcp": {
      "serverUrl": "https://mcp.gatewaylines.com"
    }
  }
