The best argument against my MCP server came from Anthropic

Building in public You know the risk before you start. Everyone tells you: do not build something the platform could ship. You build it anyway, because you need it and nobody has it. Then one Tuesday the release notes arrive. What the months actually looked like I want to be precise about the cost, because the cost is the reason the release notes hit the way they did. Two hours of sleep on a normal night — not one heroic week, the normal shape of the last few months. Work during the day, build in the evening, debug until the birds started. Weekends were the good days, because nobody interrupted. What got built in that time: a memory layer for AI coding assistants. It saves what was learned after a fix and reads the relevant parts back before the next task. It runs over MCP, so it works in whatever editor you happen to open. It survives restarts, model upgrades and switching tools. I did not build it as a business idea. I built it because I was tired of explaining my own four servers to an assistant every single morning. The hour the release notes landed Anthropic shipped memory into Claude Code. Not "context improvements", not "a longer window". The word in the release notes was memory — the same word I had been using for months to describe the thing I was building. I read it twice. Then I sat there and did the arithmetic that everybody in that position does: months of evenings, the sleep, the weekends — against one line in someone else's changelog. The thought was not complicated. It was three words long. Who needs mine? If you have never had a platform ship your feature, the closest thing I can describe is finding out the thing you have been carrying uphill was already at the top. Not that it was wrong. That it was unnecessary. I did not open the editor that evening. That is the honest version. I read the docs, I read them again, and I went to bed early for the first time in months, which is a strange way for a bad day to end. Why the fear was rational, not dramat
