OpenDota MCP Server is a Model Context Protocol (MCP) server that exposes the OpenDota API through a standard MCP interface, allowing LLMs and AI assistants to retrieve real-time Dota 2 statistics, match data, player information, and more. It provides access to player profiles, statistics, and match history; detailed match information; professional players and teams; hero statistics and rankings; and player search by name. The server includes a predefined set of data retrieval tools such as get_player_by_id, get_player_recent_matches, get_match_data, get_player_win_loss, get_player_heroes, get_hero_stats, search_player, get_pro_players, get_pro_matches, get_player_peers, get_heroes, get_player_totals, get_player_rankings, get_player_wordcloud, get_team_info, get_public_matches, and get_match_heroes to cover common use cases. Installation is supported via Smithery or manual setup, and running can be done directly or through Claude Desktop integration. An OpenDota API key is required (supplied via OPENDOTA_API_KEY). The README also includes example configurations and a client tool for testing, making this suitable for developers and AI systems that need structured, real-time Dota 2 data.
