Summer Engine
summer-engine · MCP server
Summer Engine is a desktop game engine, and this package connects your AI coding agent to it. Through its MCP server your agent can build scenes, write scripts, play the game, take screenshots and read errors. Bundled skills cover movement, combat, multiplayer, VFX, audio, UI and level design. A command line downloads the engine app, signs you in, creates projects from templates and, as a preview feature, publishes games to Summer's store.

Why it's useful
Your agent can build, play and check a whole game in the engine and pick the project up again where an earlier session stopped.
What you could do with it
- Ask your agent to build a scene with scripts and physics, then play it and read any errors.
- Have your agent take screenshots of the running game to check its own work.
- Start a new project from a platformer, racing or roguelike template, then ask your agent to build on it.
Written from its documentation: what it says it can do, not what our checks found.
Maintenance
Not measuredNo release date is on record for this package yet. The nightly publisher check records one as it reaches each npm package, about once every ten nights.
Release activity only: it says nothing about quality or safety, and a finished small package can be fine without releases. How it is measured
What this does not cover
- Everything. Treat it as you would software from anywhere else.
Receipt history: every signed receipt for every version of this listing, and what changed between them.
In its maker's words
Local Summer CLI and MCP server for Summer Engine. Install and run the engine, connect Claude Code, Cursor, Codex, Gemini, and other agents, and build real games with bundled skills, hooks, and plugins.

Static scanned
- What it establishes
- Its published package, or for a hosted server its source repository at a recorded commit, was read file by file, without running it, by every check in our current scan.
- What it does not
- How it behaves when it runs, or anything the scan does not read yet: several rubric checks, the repository's history, and compiled code in folders named dist or build. For a hosted server, that the endpoint runs the code that was read. The ooruby Index sets out exactly what was read.
- Exactly what was read
- Version 3.4.1, the file with digest sha512-uzG89ns0zWst3+RsseoyFgW3lNsEp3wk+9fnmY20Hvqozt95HiQ8sNpC4GqyozfH1Jcwo0Pu78vgTIdWbSA80w==, as the registry publishes it. A published version cannot be replaced, so this names the same bytes for anyone who checks.
- Authentication
- Runs locally. No hosted endpoint is listed for this package. You run it on your own machine, so there is no endpoint of ours to authenticate against.

No build provenance published. The repository above is the one the publisher declared, and nothing links it to the package you would install. That is not a mark against this listing, since most packages are published this way, but it is a check nobody can run.
