1. Node.js runtime environment
2. (Optional) LeetCode session cookie for authenticated API access

To install leetcode-mcp-server for Claude Desktop automatically via Smithery:

npx -y @smithery/cli install @jinzcdev/leetcode-mcp-server --client claude

npm install @jinzcdev/leetcode-mcp-server -g npx -y @jinzcdev/leetcode-mcp-server --site global

npx -y @jinzcdev/leetcode-mcp-server --site global --session <YOUR_LEETCODE_SESSION_COOKIE>

Alternatively, you can clone the repository and run it locally:

json { "mcp": { "servers": { "leetcode": { "type": "stdio", "command": "npx", "args": ["-y", "@jinzcdev/leetcode-mcp-server"], "env": { "LEETCODE_SITE": "global", "LEETCODE_SESSION": "<YOUR_LEETCODE_SESSION_COOKIE>" } } } } } ``


User-specific data access requires LeetCode session authentication:

1. Log in to LeetCode (Global or China site) 2. ExtractLEETCODE_SESSIONcookie from browser developer tools 3. Configure server with--session flag or LEETCODE_SESSION` environment variable
