MCP Server for Transit API

An MCP server for Transit API, a Japanese public transit API built on https://api.transit.ls8h.com/.

This package exists as a local npm / npx-based wrapper and as a base for future wrapper tools and experiments. It also includes lightweight result previews, which may make the first-step UX a little smoother for LLMs.
