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. Exposed over MCP by the aoc mcp mcp server, that capability becomes something an assistant can invoke while it works, not something you go and do afterwards.
Setup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client. The configuration blocks on this page cover the common clients.
Everything the assistant can do here goes through one of these:
GetAocProgress — The GetAocProgress tool exposed by this serverSubmitAnswer — The SubmitAnswer tool exposed by this serverGetInputResource — The GetInputResource tool exposed by this serverYou will need one environment variable: SESSION_COOKIE. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
Plenty of developer tooling servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Aoc MCP's toolset — GetAocProgress, SubmitAnswer, GetInputResource — is a fair guide to whether it matches your workflow. It is maintained by mazharenko; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
