# interactive-leetcode-mcp

Wires LeetCode into your agent: fetch problems, step through hints, run sample tests locally, submit code. Handy when you grind interview prep inside the chat.

## What it does

The server gives the agent access to LeetCode problems and your account. You sign in once: the agent opens the browser, you log in and hand over two cookie values, `csrftoken` and `LEETCODE_SESSION`, and the server verifies them before saving. From there it can pull a problem by slug, search by difficulty or tag, and fetch the daily challenge.

Practice happens through sessions. `start_problem` opens or resumes a problem, `request_hint` walks you up the hint ladder one step at a time, and community editorials stay locked until you reach the last level. `run_local_tests` executes your code against the sample cases in a local subprocess; installed runtimes are required, and `runner_doctor` lists which ones it finds.

Submitting goes through `submit_solution`, which returns the verdict along with runtime and memory figures. The project is under active development, so expect rough edges. You need Node.js v20 or newer, a LeetCode account, and a browser for the login step.

## Requirements
- Needs: Node.js (commands run via npx)

## Install

### Claude Code (native platform)

codex mcp add interactive-leetcode-mcp -- npx -y @sperekrestova/interactive-leetcode-mcp
```

### Cursor

**Config file**
File `.cursor/mcp.json`:
```json
{
    "mcpServers": {
        "interactive-leetcode-mcp": {
            "command": "npx",
            "args": [
                "-y",
                "@sperekrestova/interactive-leetcode-mcp"
            ]
        }
    }
}
```

### GitHub Copilot

            "command": "npx",
            "args": [
                "-y",
                "@sperekrestova/interactive-leetcode-mcp"
            ]
        }
    }
}
```

### Gemini CLI

**Platform CLI**
```bash
gemini mcp add interactive-leetcode-mcp npx -y @sperekrestova/interactive-leetcode-mcp
```

## When to use it
- work a LeetCode problem with hints that unlock in stages
- try a solution on sample cases before submitting
- find problems by difficulty and topic
- submit code and read the verdict with runtime stats
- open an editorial after giving the problem a real try

## Example prompts
- Authorize with LeetCode and walk me through it
- Start the two-sum problem in Python
- Give me a hint on the current problem
