### Description (declared)

# CSES MCP Server

*Your AI assistant's gateway to [CSES](https://cses.fi) (Code Submission Evaluation System)* 🧩

## 🤔 What is this?

`cses-mcp` is a Python-based MCP (Model Context Protocol) server that lets
an MCP-compatible client (like Claude Desktop or Claude Code) act on your
behalf on CSES: browsing problems, reading problem statements, submitting
solutions, and checking submission history/verdicts.

As far as I know, CSES has no public API, so all data access is via scraping authenticated HTML
pages and posting to existing web forms using your own session cookie.

### Why?

CSES is one of the best free problem sets for learning competitive
programming, but working through it usually means a lot of manual tab-
switching: reading a statement, writing code elsewhere, coming back to
submit, then digging through a verdict page to figure out what went wrong.
This project turns that whole loop into a conversation — ask an AI
assistant to find you a problem, explain the statement, help you reason
through an approach, submit your solution, and diagnose a wrong verdict,
all without leaving the chat. The goal isn't to solve problems *for* you
(though it can) — it's to make the feedback loop tight enough that you
actually learn faster: get hints instead of full solutions when you want
them, understand *why* a submission got Wrong Answer or Time Limit
Exceeded, and use past-attempt history to see your own progress over time.

## 🚀 Quick Start

Pick whichever fits — Option A if you just want to use it, Option B if
you're editing the code.

### Option A — Copy-paste (no local clone)

Paste this straight into your MCP client config — `uvx` fetches and runs
the published package, no clone, no `uv sync`, no `.env` file to manage:

```json
{
  "mcpServers": {
    "cses-mcp": {
      "command": "uvx",
      "args": ["qhung-cses-mcp@latest"],
      "env": {
        "PHPSESSID": "<your CSES session cookie>"
      }
    }
  }
}
```
