LeetCode MCP Server connects AI assistants to LeetCode's extensive library of coding problems, user profiles, and competitive programming data. It provides fast, programmatic access to algorithmic challenges and contest statistics to support coding interview preparation and technical assessment workflows. Key capabilities include: - Search problems with filters for difficulty level (Easy, Medium, Hard) and topic tags like arrays, dynamic programming, and trees - Retrieve daily coding challenges for consistent practice routines - Access detailed user profiles including submission history and solved problem counts - Query contest rankings and competition performance data - Flexible integration via both command-line interface and programmable JavaScript/TypeScript API
