Connect OECD Data to Claude
Query OECD Data directly from Claude. Arlet links the two through one MCP connection and takes care of API keys.
Connects your AI client to the OECD SDMX API (sdmx.oecd.org), the backend of OECD Data Explorer.
Tools:
- search_oecd_dataflows: keyword search over OECD-provided dataflows (the full list is cached; the first call can take ~10 seconds).
- get_oecd_dataflow_dimensions: dimension order and codes for one dataflow; shows the exact key template for the data query.
- get_oecd_data: observations for a dimension key (empty segment = wildcard, or 'all'), with lastNObservations control.
Implementation note: the OECD service returns HTTP 500 unless an Accept-Language header is sent; this server handles that. Attribution: data are from OECD Data Explorer (https://data-explorer.oecd.org).
