Unmeasured means there is not enough evidence to decide. How these checks work

Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 1138 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-11-25, serverInfo.name International Classifications MCP.

  • Pass
    Lists tools

    tools/list returned 10 tools.

  • Pass
    Current protocol

    Negotiated 2025-11-25. The bar is 2025-06-18 or newer.

  • Pass
    HTTPS

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 1138 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 1138 ms over 1 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

  • Not measured
    Free tier cited

    No publisher quote has been checked.

Tools

  • Pass
    Tools described

    Every tool description is at least 20 characters.

  • Pass
    Valid input schemas

    Every inputSchema is a JSON Schema object.

  • Fail
    Parameters documented

    0 of 27 parameters have a description (0%). The bar is 80%.

  • Pass
    Safety hints

    Every tool sets readOnlyHint or destructiveHint.

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

  • Not measured
    Website matches publisher

    This namespace is not a reverse domain, so the website comparison does not apply.

  • Pass
    Source repo linked

    A repository URL is on file.

  • Pass
    Repo owner matches

    The GitHub repository owner matches the namespace login.

  • Pass
    Recently updated

    Updated 2026-10-01T03:30:36.109988Z, within 180 days.

  • Not measured
    Open-source licence

    The GitHub licence lookup has not returned an OSI result yet.

Capabilities

Tools 10

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.

Discovered
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.

Discovered
get_classification

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

Discovered
get_code_definition

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

Discovered
list_classifications

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

Discovered
list_codelists

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

Discovered
map_codes

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

Discovered
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.

Discovered
search_codes

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

Discovered
validate_codes

Validate exact codes against one named classification version.
