xby-osrs-stat: Real-Time OSRS Player Data and Leaderboard Service

xby-osrs-stat is an MCP server plugin for DeepSeek Harness (DSH) that provides real-time data services for *Old School RuneScape*. It allows agents to directly obtain comprehensive player data, skill leaderboards, and activity leaderboards, as well as perform player data comparisons. Users must first obtain an API key from the official website and configure it using `set_xby_apikey`, after which they can invoke features such as `get_player_stats` and `get_skill_leaderboard` in conversation. The plugin is open source and released under the MIT License, making it suitable for agent applications that need to integrate OSRS game data.
