xby-12306-ticket-purchase-search: MCP-Based 12306 Ticket Booking Search Plugin

This plugin encapsulates the 12306 ticket purchase service based on the MCP protocol, aiming to address the data access challenges that large models face when retrieving specific ticket information. It offers core functions including authentication, station code lookup, available ticket queries, transfer routing options, and train stopover information retrieval. Developers must obtain an API key from the Xiao Ben Yang official website and configure it using the `set_xby_apikey` tool. GitHub installation is recommended. Currently, transfer ticket queries return only the first 10 results.
