Nothing serious here today

Today is the operative word: we check Tokkyo Maru every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

tokkyo

tokkyo_analyze

発明（名称・技術分野・課題・解決手段・技術事実）を渡すと、特許性を事前診断する。IPC候補・新規性喪失(特許法30条)・記載要件・発明適格性・進歩性を◯△✕で自己診断し、先行技術調査の角度とクエリも返す。代理出願はしない(本人/弁理士支援)。最終判断は弁理士。

tokkyo_check

tokkyo.json を渡すと、新規性喪失(特許法30条)・記載要件(サポート/実施可能)・発明適格性・進歩性を、その場で決定論的に◯△✕判定する。bim.house の houki_check(建築基準法その場判定)の特許版。登録可否の法的確定ではない(最終は弁理士)。

tokkyo_draft

発明から、特許明細書一式の骨子(tokkyo.json正本＋特許請求の範囲＋明細書セクション＋要約)を決定論生成して返す。bim.house の bim.json／商標まるの shohyo.json に相当。tokkyo_check も同梱。

Tokkyo Maru — questions

Answers built from our own checks of this server.

What can Tokkyo Maru do?

It exposes 3 tools, read directly from the server on our last check. Among them: tokkyo_analyze, tokkyo_check, tokkyo_draft. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Tokkyo Maru working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 825 ms. The bar chart above shows every period we have measured.

How do I connect Tokkyo Maru?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Tokkyo Maru need an API key?

No. Tokkyo Maru completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Tokkyo Maru?

It answers our handshake in 825 ms on average, which is faster than 9% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
