Tariff Code Compliance Explorer with MCP: Examples

These JSON-RPC examples use placeholder versions and node IDs. Always call list_tariff_systems first and use the exact system and version returned at runtime.

List tariff systems

{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "list_tariff_systems",
    "arguments": {}
  }
}

Resolve a tariff code

{
  "jsonrpc": "2.0",
  "id": 2,
  "method": "tools/call",
  "params": {
    "name": "resolve_nodes",
    "arguments": {
      "system": "US_HTS",
      "version": "<version from list_tariff_systems>",
      "selector": {
        "source_key": {
          "scheme": "us_hts.code",
          "value": "9506"
        },
        "kinds": ["classification"]
      }
    }
  }
}

Search native nodes

{
  "jsonrpc": "2.0",
  "id": 3,
  "method": "tools/call",
  "params": {
    "name": "search_nodes",
    "arguments": {
      "system": "US_HTS",
      "version": "<version from list_tariff_systems>",
      "query": "sports equipment",
      "kinds": ["classification"],
      "locales": ["en"]
    }
  }
}

Traverse related nodes

{
  "jsonrpc": "2.0",
  "id": 4,
  "method": "tools/call",
  "params": {
    "name": "traverse_nodes",
    "arguments": {
      "system": "US_HTS",
      "version": "<version from list_tariff_systems>",
      "start_node_ids": ["<node id returned by resolve_nodes or search_nodes>"],
      "direction": "both",
      "relations": ["parent_of", "applies_to", "references", "defines"],
      "max_depth": 2,
      "max_nodes": 100,
      "max_edges_per_node": 50
    }
  }
}
