LeetCode MCP server

This is a small helper that connects your AI assistant to LeetCode, the site where people practice coding problems. Once it is set up, you can ask your AI about a problem, a user, or your own progress, and it will go fetch the answer for you. It is handy if you practice coding, prepare for interviews, or just like keeping track of your solved problems.

What this MCP server does

You ask your AI something about LeetCode, like the daily challenge or a problem you are stuck on. The AI passes your request to this helper. The helper talks to LeetCode's own systems and brings the answer back. Then the AI shows it to you in the chat, as a list, a summary, or a block of text. If you log in, it can also read and change your private things, like your notes.

What it gives back to you

You get answers in the chat: problem descriptions, lists of problems, solution text, user stats, or your own submission history.

Everything appears as normal text you can read and copy.
