MCP Nbb runs on your own machine — the client starts it, so there is no endpoint to ping. 80 installs a week from pypi. Last commit 13 Apr 2026.
MCP server for the National Bank of Belgium SDMX statistical API (221 dataflows).
Today is the operative word: we check MCP Nbb every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
