Jct Transition Lint 2026

A local npx MCP server named Jct Transition Lint 2026 that appears intended to lint Japanese consumption-tax invoice and purchase codes for the 2026 rate…

What you can do

• The manifest lists no tools, so the exact operations are unknown.
• The registry description frames it around the end of the 80% deduction on 30 September 2026 and the move to 70% from 1 October 2026 under the Reiwa 8 tax reform.
• It appears aimed at flagging leftover 0.8 and 0.5 values in invoice and purchase codes, per-line rounding, and registration numbers that are not in the T plus 13-digit format.
• The README only describes VS Code themes by the same publisher and does not document any usage.

When to use it

Possibly worth considering if you maintain Japanese invoice or purchase data and want an assistant to check codes and rounding ahead of the October 2026 tax-rate change. Because no tools are listed and the README does not document the server, confirm what it actually does before relying on it.

Requirements

Runs as a local process via npx from the npm package @readystack/jct-transition-lint-2026, so Node.js and network access for the package download are needed. No authentication, environment variables or headers are declared. Desktop only; no web executable.
