{"jsonrpc":"2.0","id":1,"method":"tools/list"}sdmx_dataflow_structure — 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" }).sdmx_codelist — 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" }).sdmx_find_dataflow — 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.Code samples (curl / TypeScript / one-click client install), schemas, and the live playground are on the pack page:
