What is the Doom MCP server?

Doom MCP server exists for a simple reason — assistants are far more useful when they can act on Doom directly instead of describing what you should do. Play DOOM via MCP - works with Claude Code, Cursor, and any MCP client.

What you get

Play DOOM in Claude Code, Cursor, or any MCP-compatible client. The AI sees the game, fights demons, navigates levels, and reports what's happening - or you direct it move by move.

What the assistant can call

Once Doom is connected, these are the calls the assistant has available:

  • doom_start — Start or restart DOOM. Safe to call at any time — if a game is already running it restarts cleanly without needing a new session
  • doom_action — Advance the game. All listed actions are held simultaneously for the tick duration
  • doom_screenshot — Save a full-resolution 320x200 screenshot to the system temp directory and open it in the default image viewer. Does not advance the game (beyond a

Setting it up

doom-mcp on npm is all you need. Most clients run it directly, so configuration is a few lines and a restart.

Configuration and credentials

You will need one environment variable: DOOM_WAD_PATH. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.

Choosing this one

Plenty of browser automation 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. Doom's toolset — doom_start, doom_action, doom_screenshot — is a fair guide to whether it matches your workflow. It is maintained by gunnargrosch; worth a glance at recent repository activity before you build anything load-bearing on it.

We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.

Before you rely on it

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the doom mcp server does with a few real requests.
