TDQS

A3.7/5.0

Scored across 10 tools

Disambiguation4/5

Most tools have clearly distinct purposes, but browse_hierarchy and list_codelists both can reveal codelists, and recommend_classifications versus list_classifications both list classifications, creating minor selection ambiguity. The descriptions help differentiate them, keeping confusion low.

Naming Consistency5/5

All tool names follow a consistent snake_case verb_noun pattern (e.g., list_classifications, get_code_definition, search_codes). No mixed conventions or vague verbs appear.

Tool Count5/5

Ten tools is well-scoped for a classification server, covering discovery, navigation, search, validation, mapping, export, and recommendation without redundancy. Each tool appears to earn its place.

Completeness5/5

The set provides full lifecycle coverage for a read-only authoritative classification service: listing families/codelists, getting metadata, browsing hierarchies, searching codes, validating codes, mapping correspondences, exporting choice lists, and recommending classifications. No obvious gaps exist.

Available Tools

10 tools
browse_hierarchyBrowse classification hierarchyA
Read-onlyIdempotent
Inspect

Browse top-level nodes or immediate children. Curated families return node_kind=codelist containers at root; pass that code as parent_code to browse its options.

Inputs: classification_id (required), limit, parent_code. Returns: result

export_choice_listExport a choice listB
Read-onlyIdempotent
Inspect

Return a structured choice list at a selected hierarchy level. MICS exports require one codelist_id and never merge unrelated answer lists.

Inputs: classification_id (required), level, limit, format, +1 more. Returns: rows, level, format, warning, +4 more

get_classificationGet classification metadataA
Read-onlyIdempotent
Inspect

Get authoritative metadata and coverage for one classification_id returned by list_classifications.

Inputs: classification_id (required). Returns: id, name, domain, status, +8 more

get_code_definitionGet code definitionB
Read-onlyIdempotent
Inspect

Retrieve one exact code or codelist container, including its node_kind, hierarchy position and explanatory notes.

Inputs: code (required), classification_id (required). Returns: code, label, level, score, +11 more

list_classificationsList classificationsA
Read-onlyIdempotent
Inspect

List classification families, versions, custodians, coverage and licensing notes. Start here when the correct standard is unknown.

Inputs: domain, status. Returns: result

list_codelistsList codelistsA
Read-onlyIdempotent
Inspect

List independent option lists within a classification before searching or exporting one list.

Inputs: classification_id (required). Returns: result

map_codesMap codes between versionsB
Read-onlyIdempotent
Inspect

Apply official stored correspondences and expose splits, merges, changed meanings and unmapped codes. Never assume one-to-one equivalence.

Inputs: codes (required), source_classification_id (required), target_classification_id (required). Returns: results, sources, warnings, source_classification, +1 more

recommend_classificationsRecommend classificationsA
Read-onlyIdempotent
Inspect

Return a deterministic ranked shortlist of all relevant classification concepts and codelists. Ranking supports user choice; it is not an automatic selection. Include answer options and context.

Inputs: question_text (required), limit, answer_options, survey_context. Returns: warnings, next_action, recommendations

search_codesSearch classification codesB
Read-onlyIdempotent
Inspect

Full-text search labels and notes. Results restrict to one option list only when codelist_id is explicitly supplied.

Inputs: query (required), limit, codelist_id, classification_ids. Returns: query, total, results, warnings

validate_codesValidate classification codesB
Read-onlyIdempotent
Inspect

Validate exact codes against one named classification version.

Inputs: codes (required), classification_id (required). Returns: results, valid_count, invalid_count, classification_id
