Install Advent of Code MCP Server in your MCP client (Claude Desktop, Cursor, Windsurf, and others).

Repository: https://github.com/mazharenko/aoc-mcp

This project is developed for educational purposes. The server aims to simplify interactions with the Advent of Code website and enhance the puzzle-solving workflow.

However, building aself-submitting apparound solutions will likely be the most efficient approach.

- Gets star count for a specified Advent of Code year
- Parameters:year(int)
- Returns:Stars(int)

- Submits an answer for an Advent of Code day part. If the previous answer has been given too recently, waits until it can be submitted (with progress notifications).
- Parameters: int year, int day, int part, string answer
- Returns:Correct/Incorrect/TooLow/TooHigh

- Retrieves the personal puzzle input
- Parameters: int year, int day
- Returns: input text as an embedded resource

Resource template for the personal puzzle input

> submit "42" for 2024/10/1

> get aoc input for 2024/10 and save it

> Get aoc input for 2024/10 and write it to a new file. Run aoc program for year 2024 day 10, pass 2024 and 10 as positional arguments and the created file path as --input-file argument. Read the answers from the output and submit them.
