Fortitude21 Dangerous Goods MCP

An official MCP server providing six JSON endpoints for dangerous goods and packaging compliance. It allows AI agents to look up UN number packaging requirements, decode UN packaging marks, check IBC inspection dates, calculate ADR points for mixed loads, determine spill pallet bund sizes, and calculate jerry can quantities without requiring an API key.

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 fortitude21-dangerous-goods-mcp https://fortitude21.com/mcp

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 fortitude21-dangerous-goods-mcp --url https://fortitude21.com/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable fortitude21-dangerous-goods-mcp in your MCP settings.

Cursor configuration

{
  "mcpServers": {
    "fortitude21-dangerous-goods-mcp": {
      "url": "https://fortitude21.com/mcp"
    }
  }
}

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": {
    "fortitude21-dangerous-goods-mcp": {
      "type": "streamableHttp",
      "url": "https://fortitude21.com/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start fortitude21-dangerous-goods-mcp and inspect its tools.

VS Code configuration

{
  "servers": {
    "fortitude21-dangerous-goods-mcp": {
      "type": "http",
      "url": "https://fortitude21.com/mcp"
    }
  }
}

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 fortitude21-dangerous-goods-mcp https://fortitude21.com/mcp

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": {
    "fortitude21-dangerous-goods-mcp": {
      "url": "https://fortitude21.com/mcp"
    }
  }
}

Windsurf

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

Windsurf configuration

{
  "mcpServers": {
    "fortitude21-dangerous-goods-mcp": {
      "serverUrl": "https://fortitude21.com/mcp"
