## MCP tools (3)

### `sdmx_dataflow_structure` (~387 tokens)

Get the structure of one dataflow from any SDMX 2.1 registry: its ordered dimensions and, for each, the valid codes with labels. This answers "what do the codes in dataflow X mean" and "what key do I need to pull data from it" — use it before calling a registry-specific get_data tool. Covers eurostat, oecd, ecb, unsd (UN Statistics Division via the data.un.org SDMX hub), imf, bis, ilo, abs. For ILO or ABS dataflows, prefer the ilostat/abs-au packs' own dataflow_structure tool — this one exists mainly for the other six. Example: sdmx_dataflow_structure({ registry: "eurostat", dataflow: "une_rt_m" }) or sdmx_dataflow_structure({ registry: "bis", dataflow: "WS_CBPOL" }).

Input parameters:

- `agency` (string): Override the registry's default maintaining agency id, e.g. "OECD.SDD.NAD" for an OECD dataflow published by a specific directorate. Most callers can omit this.
- `dataflow` (string, required): Dataflow id, e.g. "une_rt_m" (Eurostat), "WS_CBPOL" (BIS), "EER" (IMF). Case usually does not matter but pass it exactly as published.
- `max_codes_per_dimension` (number): Cap codes returned per dimension (default 50, max 500). Codelists like country or region lists can have thousands of codes.
- `registry` (string, required): Which SDMX registry to query: eurostat, oecd, ecb, unsd, imf, bis, ilo, abs.
- `version` (string): Dataflow version, e.g. "1.0". Defaults to "latest".

### `sdmx_codelist` (~298 tokens)

Fetch one codelist's code->label mapping by id, from any SDMX 2.1 registry, without needing a dataflow. Use this when you already know a codelist id (e.g. from sdmx_dataflow_structure's `codelist` field, or from a dataset's documentation) and just need the codes. Example: sdmx_codelist({ registry: "ilo", id: "CL_ECO" }) or sdmx_codelist({ registry: "eurostat", id: "GEO", filter: "France" }).

Input parameters:

- `agency` (string): Override the registry's default maintaining agency id for this codelist, e.g. "SDMX" for a shared CL_FREQ. Most callers can omit this.
- `filter` (string): Case-insensitive substring filter on code id or label, e.g. "france", "quarterly".
- `id` (string, required): Codelist id, e.g. "CL_ECO", "GEO", "CL_FREQ".
- `limit` (number): Max codes to return (default 100, max 1000).
- `registry` (string, required): Which SDMX registry to query: eurostat, oecd, ecb, unsd, imf, bis, ilo, abs.
- `version` (string): Codelist version. Defaults to "latest".

### `sdmx_find_dataflow` (~251 tokens)

Keyword-search a registry's full dataflow catalogue by id or name substring. Use this to find the dataflow id to pass to sdmx_dataflow_structure when you only know a topic. Example: sdmx_find_dataflow({ registry: "bis", query: "credit" }) or sdmx_find_dataflow({ registry: "oecd", query: "unemployment" }). For Eurostat specifically, the eurostat pack's own search_datasets tool searches its ~10,000-entry table of contents with richer metadata (last-update dates, time coverage) and is usually the better choice.

Input parameters:

- `agency` (string): Restrict to one maintaining agency id instead of the registry default, e.g. "OECD.SDD.NAD".
- `limit` (number): Max results to return (default 50, max 300).
- `query` (string, required): Case-insensitive substring to match against dataflow id or name, e.g. "unemployment", "credit", "exchange rate".
- `registry` (string, required): Which SDMX registry to query: eurostat, oecd, ecb, unsd, imf, bis, ilo, abs.

## Common questions

### What is the Sdmx Structure MCP server?

Sdmx Structure is an MCP server listed in the public MCP registry as io.github.pipeworx-io/sdmx-structure. SDMX Structure MCP, dataflow dimensions and code lists for any SDMX 2.1 registry: Eurostat, OECD… This page covers its npm package (@pipeworx/mcp-sdmx-structure).

### Is the Sdmx Structure MCP server safe to use?

Sdmx Structure scores 82 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 6 November 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Sdmx Structure MCP server expose?

Sdmx Structure exposes 3 tools: sdmx_dataflow_structure, sdmx_codelist, sdmx_find_dataflow. Their descriptions and schemas cost roughly 936 tokens of context every time the server is loaded.

### Is the Sdmx Structure MCP server still maintained?

Sdmx Structure is still listed as active in the MCP registry. We last reached this channel on 6 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the Sdmx Structure MCP server under?

Sdmx Structure declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.

### What did VerifyMCP test on the Sdmx Structure MCP server?

VerifyMCP ran 16 checks on Sdmx Structure, covering Malware scan, Known CVEs, Install scripts, Dependency health and 12 more. Endpoint Security and Transport & Reachability do not apply to an npm package, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
