@pipeworx/sdmx-structure
Dataflow dimensions and code lists — "what do the codes in this dataset mean" — for any SDMX 2.1 statistical registry: Eurostat, OECD, the European Central Bank, the UN Statistics Division (via the data.un.org SDMX hub), the IMF, the Bank for International Settlements, ILOSTAT, and the Australian Bureau of Statistics. This is the STRUCTURE half of SDMX, distinct from pulling observations — use it to decode a dimension's codes or to learn the key order a registry's own get_data tool needs.
Part of Pipeworx — an MCP gateway connecting AI agents to 1866+ live data sources. This is an independent, unofficial integration — not affiliated with, endorsed by, or published by the upstream provider.
Tools
sdmx_dataflow_structure(registry, dataflow, agency?, version?, max_codes_per_dimension?)— the ordered dimensions of one dataflow, each with its codelist's code→label pairs (capped per dimension, with a truncation flag and the true total count). Resolves the dataflow's real DSD (Data Structure Definition) reference rather than assuming the dataflow id equals the DSD id — they differ for many flows (Eurostat'sUNE_RT_Mdataflow v1.0 points at DSDUNE_RT_Mv155.0; BIS'sWS_CBPOLdataflow points at a differently named DSD,BIS_CBPOL).sdmx_codelist(registry, id, agency?, version?, filter?, limit?)— one codelist's code→label pairs by id alone, with no dataflow needed. Useful once you already know a codelist id (fromsdmx_dataflow_structure'scodelistfield, or from documentation) and just want the codes, optionally filtered by a substring.sdmx_find_dataflow(registry, query, agency?, limit?)— keyword search across a registry's dataflow catalogue by id or name, to find the id to pass tosdmx_dataflow_structure.
Registries
registry | Source | Structure format | Default agency |
|---|---|---|---|
eurostat | Eurostat | XML only (confirmed live — every JSON Accept/format combination 406s) | ESTAT |
oecd | OECD | JSON | all |
ecb | European Central Bank | XML only | ECB |
unsd | UN Statistics Division (data.un.org SDMX hub) | JSON | all |
imf | IMF | JSON | all |
bis | Bank for International Settlements | JSON | BIS |
ilo | ILOSTAT | JSON | ILO |
abs | Australian Bureau of Statistics | JSON | ABS |
OECD, IMF and UNSD default to agency `all`, not a single agency — this is load-bearing, not a placeholder. All three registries split their catalogue across many maintaining sub-agencies and there is no single agency id that covers it:
- OECD: there is no agency literally called
"OECD"— every dataflow is published under a directorate (OECD.SDD.NAD,OECD.ELS.JAI,OECD.EDU.IMEP, ...; 52 distinct agency ids observed live, some mirroring in ESTAT and IAEG-SDGs flows too). Querying agency"OECD"404s with"No Results Found"on both the catalogue listing and a single-dataflow lookup — this is the live defect fleet #2839's follow-up caught (sdmx_find_dataflow({registry:"oecd", query:"unemployment"})404ing). - IMF: ten sub-agencies (
IMF.STA,IMF.MCD,IMF.SPR,IMF.AFR,IMF.MCM,IMF.FAD,IMF.WHD,IMF.APD,IMF.RES, plus the externalISORA).IMF.STAalone 200s — which is why this looked fine at first — but covers only 190 of 223 dataflows; the other 33 are every regional economic outlook (APDREO,AFRREO,WHDREO, ...) and the fiscal affairs dataflows. - UNSD: the hub mirrors ESTAT, IAEG-SDGs, UIS and World Bank dataflows under THEIR agency ids alongside UNSD's own ~4. Querying agency
"UNSD"200s but returns only UNSD's own flows (1.4KB observed) where"all"returns the whole hub (4.4KB, ~15 dataflows).
"all" resolves a SINGLE dataflow lookup identically to the dataflow's real sub-agency for all three (verified side by side, byte-identical response, for an OECD.SDD.NAD flow, an IMF.APD flow and an ESTAT-owned UNSD-hub flow) — so there is no coverage cost to defaulting to it. Pass agency only to narrow a search to one sub-agency, or to match a different registry's single-agency default (Eurostat/ECB/BIS/ILOSTAT/ABS, each already its own one agency).
Not included: Stats NZ. Its SDMX endpoint requires a platform API key (Ocp-Apim-Subscription-Key, injected by the gateway from PLATFORM_STATSNZ_KEY) and a literal, non-URL-encoded comma in its flowRef path segment — neither fits this pack's keyless, URL-encoded-path design, and the stats-nz pack already ships a dedicated structure tool. See that pack.
Overlap with existing packs — read before calling this for ILO or ABS. The ilostat pack already ships dataflow_structure for ILO dataflows, and the abs-au pack already ships dataflow_structure for ABS dataflows — both inline codes directly, the same job sdmx_dataflow_structure here does. This pack supports registry: "ilo" and registry: "abs" only for the standalone sdmx_codelist lookup (a codelist by id, no dataflow needed) that neither of those packs exposes. Prefer ilostat's / abs-au's own `dataflow_structure` for an ILO or ABS dataflow — every response from this pack for those two registries repeats that in an overlap field.
Auth
Keyless. No auth on any of the eight registries above.
Data sources
- Eurostat SDMX 2.1 REST API — https://ec.europa.eu/eurostat/api/dissemination/sdmx/2.1 — structure endpoints (
/dataflow,/datastructure,/codelist) answer SDMX-ML XML only; every JSON Accept header andformat=SDMX-JSONquery param this pack tried either 406s or is silently ignored (confirmed live 2026-10-08). The eurostat pack's own data endpoint (/dissemination/statistics/1.0/data) is a *different* API that does speak JSON-stat — the two are not interchangeable. - OECD SDMX 2.1 REST API — https://sdmx.oecd.org/public/rest.
- European Central Bank Data Portal — https://data-api.ecb.europa.eu/service — structure endpoints are XML only, same split the ecb pack already documents for its own
/dataflowcall (fleet #1158): the DATA endpoints speak SDMX-JSON, the STRUCTURE endpoints (/dataflow,/datastructure,/codelist) do not. - UN Statistics Division SDMX hub — https://data.un.org/legacy/ws/rest — the documented
https://data.un.org/ws/rest/...path 302-redirects here; this pack calls the redirect target directly. It is a small, multi-agency hub (~15 dataflows observed) carrying UNSD's own flows (DF_UNDATA_ENERGY,DF_UNDATA_COUNTRYDATA) alongside mirrored IAEG-SDGs, UIS and World Bank flows under their own agency ids — passagencyif a dataflow you want belongs to one of those rather thanUNSD. - IMF SDMX 2.1 REST API — https://api.imf.org/external/sdmx/2.1. IMF concept-level representation trap: some IMF dimensions carry no
localRepresentation.enumerationat all — e.g.EER'sCOUNTRYandINDICATORdimensions. Their codelist is declared on the shared CONCEPT instead: the dimension'sconceptIdentityURN points at a concept scheme (e.g.IMF:CS_MASTER_DATA), and that concept's owncoreRepresentation.enumerationis the real codelist (IMF:CL_COUNTRYforCOUNTRY). This pack follows that chain automatically; a naive implementation that only readsdimension.localRepresentationwill report those dimensions as codeless. - Bank for International Settlements SDMX 2.1 REST API — https://stats.bis.org/api/v2/structure (note the
/structuresegment — BIS nests dataflow/datastructure/codelist resources under it, unlike every other registry here). - ILOSTAT SDMX 2.1 REST API — https://sdmx.ilo.org/rest. Accept-Language trap: ILO's backend returns a bare
500 languageTag1body for any request with noAccept-Languageheader at all — reproduced with Node's/Workers'fetch(which sends none by default) but NOT with curl, confirmed live 2026-10-08. This pack sendsAccept-Language: enon every outbound request to every registry (harmless elsewhere) specifically because of this. - Australian Bureau of Statistics Data API — https://data.api.abs.gov.au/rest — the documented host
api.data.abs.gov.audoes not resolve; this is the same live host the abs-au pack already found and documented.
Size trap, all registries: fetching a DSD with references=children pulls in every codelist it uses in one response — Eurostat's UNE_RT_M alone is 3.7MB because its GEO (country/region) codelist is 2.6MB. This pack never does that: it fetches the DSD with references=none (a few KB — just the dimension list and each dimension's codelist REFERENCE), then fetches only the codelists actually needed, one at a time, each capped to max_codes_per_dimension (default 50, max 500) with a truncation flag and the true total code count.
A 404 on a structure endpoint always means "no such id" — unlike a data endpoint, there is no "dataflow exists but no observations matched" ambiguity for a structure query, so this pack does not need the data-endpoint no_records/no_dataflow split that shared/src/sdmx-miss.ts provides for other packs' get_data tools. Every 404 here comes back as a structured {error: "not_found", ...} naming sdmx_find_dataflow as the next step. A 200 that parses to zero dimensions or zero dataflows is reported as a loud upstream_parse: error, never as a silent empty result.
Quick Start
Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):
{
"mcpServers": { "sdmx-structure": { "url": "https://gateway.pipeworx.io/sdmx-structure/mcp" } } }
What this endpoint actually serves
tools/list at https://gateway.pipeworx.io/sdmx-structure/mcp returns the tools in the table above plus the shared Pipeworx meta-tools — ask_pipeworx, discover_tools, search_within, remember/recall and the rest of the gateway-wide set. So the tool count you see is larger than this table: a single-pack endpoint currently lists roughly 30 shared tools alongside the pack's own. The connection's initialize response states its exact scope, and is the authoritative answer for a given day.
This is deliberate, not multiplexing by accident. The meta-tools are what let a scoped connection answer a question this pack does not cover — via ask_pipeworx, which routes across the whole catalog — without you adding a second MCP server. There is currently no way to mount a pack endpoint without them; if the extra schemas cost you more context than the routing is worth, connect to the full gateway once rather than to several pack endpoints.
Or connect to the full Pipeworx gateway to get every pack's tools listed directly, instead of just this one's:
{
"mcpServers": { "pipeworx": { "url": "https://gateway.pipeworx.io/mcp" } } }
Both URLs reach the same gateway and the same 1866+ data sources. The only difference is which pack's tools are listed directly; ask_pipeworx reaches all of them from either one.
No MCP client? Call it over HTTP
curl -X POST https://gateway.pipeworx.io/v1/tools/sdmx_dataflow_structure \
-H 'Content-Type: application/json' \ -d '{"registry":"eurostat","dataflow":"une_rt_m"}'
No account needed for the first calls. Inspect any tool: GET https://gateway.pipeworx.io/v1/tools/sdmx_dataflow_structure. Find one: POST https://gateway.pipeworx.io/v1/tools/search_packs with {"query":"..."}.
Run it from npm
@pipeworx/mcp-sdmx-structure is a local stdio bridge to the Pipeworx gateway: your MCP client starts it with npx, and it forwards every call to the same https://gateway.pipeworx.io/sdmx-structure/mcp endpoint shown above. It needs network access; there is no offline mode.
{
"mcpServers": { "sdmx-structure": { "command": "npx", "args": ["-y", "@pipeworx/mcp-sdmx-structure"] } } }
