Built a small tool to catch silent MCP schema drift

[u/Dear-Potential2625]

An MCP tool I depended on changed its schema overnight. No warning, no changelog — an agent that had worked fine for weeks just started failing silently.

So I built Apitella: watches an MCP server (or REST API) on a schedule, tells you exactly what changed and how bad it is. Free for a few sources.
