OP.GG MCP Server is a Model Context Protocol implementation that connects OP.GG data with AI agents and platforms. It provides a standardized interface for retrieving OP.GG data via function calling, enabling AI agents to access real-time game statistics through a remote MCP endpoint (https://mcp-api.op.gg/mcp). The server exposes tools across League of Legends, TFT, and Valorant that cover champion analytics (leader boards, analysis, meta-data, skin sales), summoner data (search, game history, renewal), esports schedules and standings, TFT meta decks and item combinations, champion item builds and item recommendations, TFT play-style commentary, and Valorant maps, character meta, leaderboards, agent compositions by map, character statistics, and player match history. This MCP server can be connected directly via StreamableHttp using the supergateway, installed via Smithery, or integrated into Claude Desktop MCP configuration. It is released under the MIT License and aims to provide immediate, consumable data for AI models and agent frameworks with minimal setup.
