LeetCode MCP Server provides a bridge to LeetCode's programming problem platform through the Model Context Protocol. Developed by jinzcdev, this TypeScript implementation supports both leetcode.com and leetcode.cn sites, offering tools for accessing problem descriptions, searching by tags and difficulty, retrieving user profiles and submission history, and accessing community solution articles. The server handles authentication via LeetCode session cookies for accessing private data, and exposes resources for problem metadata and solution content, making it particularly valuable for developers seeking programming assistance, contest preparation, or algorithm learning through AI assistants.
