xby-constellation: Constellation Info Lookup and Horoscope Analysis Plugin

xby-constellation is a Model Context Protocol (MCP)-based astrology data query plugin developed specifically for DeepSeek Harness (DSH). It addresses the pain point of agents needing to maintain backend services to access domain-specific knowledge, providing complete capabilities such as basic zodiac information, rising sign calculation, daily horoscopes, and compatibility analysis. Users need to obtain an API key from the official website and configure it via `set_xby_apikey` to call various interfaces for data queries. Licensed under the MIT License, the plugin provides a standardized astrology analysis solution for the DSH ecosystem.
