概要

What is LeetCode MCP Server?

The LeetCode MCP Server is a Model Context Protocol (MCP) server that provides seamless integration with LeetCode APIs, enabling advanced automation and intelligent interaction with LeetCode's programming problems, contests, solutions, and user data. It supports both leetcode.com (Global) and leetcode.cn (China) platforms.

How to use LeetCode MCP Server?

Install the npm package globally or run it with npx. Configure it using command-line arguments (--site, --session) or environment variables (LEETCODE_SITE, LEETCODE_SESSION). Integrate with MCP‑compatible clients (e.g., VS Code) by adding a JSON configuration to your user settings. Tools are invoked through the MCP client after setup.

FAQ from LeetCode MCP Server

What are the prerequisites?

A Node.js runtime environment, and optionally a LeetCode session cookie for authenticated API access.

How do I set the site (global or China)?

Use the --site command-line argument with value global or cn, or set the LEETCODE_SITE environment variable. Command-line arguments take precedence over environment variables.

Where does the authentication session cookie come from?

The LEETCODE_SESSION cookie is obtained from your browser after logging into LeetCode. It is required for private data access such as user notes, submission details, and problem progress.

What transports does the server use?

The server communicates via stdio transport using the MCP protocol, configured through a command execution (e.g., npx).

What are the known limitations?

Notes tools are only available on LeetCode China (CN). The get_recent_submissions tool is only available on Global. Several tools require authentication.
