Overview

AI-generated overview

A remote MCP server that gives an assistant pre-filing patentability checks, draft specification outlines, and novelty-loss assessment for inventions.

What you can do
Tokkyo Maru accepts an invention description and returns a preliminary patentability diagnosis, a skeleton for a patent specification, and an assessment of novelty loss under Article 30 of the Japanese Patent Act. It is positioned as filing support for inventors or patent attorneys, not as a substitute for representation. The registry description lists no individual tools.
When to use it
Useful when someone is considering a Japanese patent filing and wants a quick preliminary read on patentability, a starting outline for a specification, or a check on whether prior disclosure may have destroyed novelty. It is a pre-check aid, not legal advice or filing representation.
Requirements
Remote streamable HTTP endpoint at no package installation. The manifest declares no authentication, no environment variables, and no headers, so no credentials appear to be needed. Network access to the endpoint is required.
Before you install
The service is described as filing support that does not act as an agent, so its output should not be treated as legal advice or a substitute for a qualified patent attorney. Invention details submitted for diagnosis are sent to a third-party remote endpoint; avoid sharing confidential or unpublished technical information you are not prepared to disclose externally.

Installation

In SourceWeft

  1. Open Tokkyo Maru in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.yukihamada%2Ftokkyo-maru/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

83% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
