Apitier runs on your own machine — the client starts it, so there is no endpoint to ping. 40 installs a week from npm. Last commit 26 May 2026.
APITier utility APIs as MCP tools: validation, UK/India address lookup, barcode/QR, data conversion.
Today is the operative word: we check Apitier every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.
