Available tools 10

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

browse

browse_hierarchy

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.

classification

get_classification

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

classifications

list_classifications

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

code

get_code_definition

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

codelists

list_codelists

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

codes

search_codes

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

export

export_choice_list

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

map

map_codes

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

recommend

recommend_classifications

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.

validate

validate_codes

Validate exact codes against one named classification version.

International Classifications MCP — questions

Answers built from our own checks of this server.

What can International Classifications MCP do?

It exposes 10 tools, read directly from the server on our last check. Among them: browse_hierarchy, export_choice_list, get_classification, get_code_definition, list_classifications, list_codelists and 4 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is International Classifications MCP working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 90 of 91 checks got a reply (98.9%), average response time 1878 ms. The bar chart above shows every period we have measured.

How do I connect International Classifications MCP?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does International Classifications MCP need an API key?

No. International Classifications MCP completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 10 of them are readable on this page. This is what we observed, not what the docs claim.

Is International Classifications MCP open source?

Yes — it is published under the MIT licence, written in Python and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
