Tariff Code Compliance Explorer with MCP: Tools

Tariff Code Compliance Explorer exposes seven read-only tools for discovering tariff systems and researching their native knowledge graphs.

Tool list

  • list_tariff_systems: list enabled tariff systems and exact versions.
  • describe_tariff_system: return one system's native profile and version-specific guide.
  • resolve_nodes: resolve a native node by source key or typed identifier.
  • search_nodes: search native tariff nodes in an explicit system and version.
  • get_node: fetch one native tariff node by opaque node ID.
  • list_node_edges: list filtered incoming or outgoing edges for one node.
  • traverse_nodes: traverse a bounded graph from one or more node IDs.

Recommended sequence

  1. Call list_tariff_systems.
  2. Use the returned system and version in later calls.
  3. Call describe_tariff_system before assuming identifier schemes, node kinds, or relations.
  4. Resolve or search for a node before using its opaque node_id in fetch or traversal calls.

Pagination and bounds

Paged tools return at most 25 items. When page.has_more is true, pass page.next_page_token back as page_token. Paged tools do not return exact totals.

Traversal is bounded by max_depth, max_nodes, and max_edges_per_node. If truncated is true, narrow the traversal instead of treating it as complete.

An over-broad search returns Search is too broad. Narrow your search and try again. Narrow the query instead of retrying it unchanged.
