Mcp Nbb

Connects Claude to the National Bank of Belgium's SDMX statistical API, exposing all 221 dataflows (exchange rates, inflation, GDP, employment, government finances) through six LLM-friendly tools. Ships with a 9MB enriched catalog so Claude can search and describe datasets without hitting the API. The query tool handles raw SDMX keys or friendly filters like `{"FREQ":"D","EXR_CURRENCY":"USD"}`, while quick shortcuts cover 18 common queries (policy rates, HICP inflation, unemployment). The compare tool aligns multiple series on a common time index with automatic frequency downsampling. Includes persistent disk caching and proper WAF headers for the NBB endpoint. Useful when you need Belgian or IMF/SDDS economic data in conversational workflows without manually navigating the data explorer.
