Original project author: [Joooook](https://github.com/Joooook) (license attribution: Jok).

This plugin is based on and optimized from the upstream 12306 query implementation, adapted for native DeepSeek Harness integration.

Reviewed commit: ff6439da6f63d7d72181abea4568abd69878c600

The station field layout and supplemental entry (`src/stations/loader.ts`, `missing-stations.ts`), ticket field positions and packed price mapping (`src/parser/ticket.ts`), raw response contracts (`src/types.ts`), and request parameters/discovery patterns (`src/client/`) are adapted from this MIT project. The MCP runtime, transports, server, CLI and model-visible helper tools are not incorporated.

Native plugin contracts follow the official tool-todo, tool authoring and plugin installation references. The project consumes published SDK packages as dependencies/peers; their distribution retains each package's own license. Agent tests use the published official testkit and a locally written, scripted adapter following its StreamChunk contract. No reference repository source tree is distributed in this package.
