Carpenter at 15, 30 years on-site, now building AI for construction. HORIZON SHIELD: a free AI that checks if your estimate is fair. Open data (JCCDB), verifiable on Bitcoin. verify me > trust me. from Hiratsuka, Kanagawa shield.the-horizons-innovation.com

A builder I trust took my coordinate-integrity design into his own live system, closed both halves, then found a real defect in my code. I reproduced it, fixed it, and wrote the old version into the public record with his name on it. The operator is a subject of the rule, not an exception.

Soon your AI won't just chat. It'll book the contractor, pick the supplier, pull your files. So how does it reach the real world? A thing called MCP. Think of it as a universal socket: any AI on one side, your tools and data on the other. One standard, not a custom wire per tool. 🧵

Nearly half of the MCP servers in the official registry cannot be checked from outside by anyone. Including by the people using them. 22,636 active entries. 12,077 declare a reachable address. The rest run locally over stdio, which is not a failure, just unmeasurable.

Found 93,983 times. Used 0 times. AI can find tools now. It cannot tell which ones to trust. A human asks "who pays this company?" An AI cannot. Nothing is written in a form it can read. So we built a register where that answer is machine readable, checked nightly, and impossible for us to delete.

試しに、スマホのAIにこう聞いてみてください。 「◯◯市で外壁塗装、いい会社ある?」 出てきた名前に、あなたの会社はありましたか。 無かったとしても、腕の問題ではありません。 「AIが読める形」になっていないだけです。 まず3分、これを見てください。 shield.the-horizons-innovation.com/yakumo/mirai/

Built a conformance checker for MCP servers today. Pointed it at my own servers. 0.0% passed. The condition we failed: declare, in a machine-readable field, who pays you. Our card answered that. In English prose. In the description. A disclosure only a human can read is not a disclosure.
