YouGame is installed from its publisher's own source and answers where it runs, so this marketplace is not in the path of a single call. There is no address here to send one to, and a panel that pretended otherwise would be showing you an answer we made up. Install it and call it from your own client — the Installation tab has the entry for each one.

Publish a browser game on YouGame: the build rules, the leaderboard SDK, pre-upload checks.
Quickstart
# 1 — run it from where its publisher ships it

# 2 — ask your agent something
> Publish a browser game on YouGame: the build rules, the leaderboard SDK, pre-upload checks.
YouGame is free: there is no plan to choose, no cap to set and nothing that can bill you.
Collected from a public index. Nobody has claimed this account, so nothing here was written by its author — claim it if it is yours.
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. Nothing here runs on your machine and nothing runs on ours: this server answers at its publisher’s own address, and what you install is the connection straight to it.
This is a public server: you run it yourself and this marketplace is not in the path. Claude Code registers it in one command. The transport below is http, as the publisher's own manifest declares it.
claude mcp add --transport http yougame-mcp https://yougame.co/mcpReconnect, or start a new session, and the tools appear in the model’s tool list.
One config entry pointing straight at the publisher’s own address — this marketplace is not in the path, and nothing from this listing executes on your machine.
8 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.
Tool surface
What the model actually sees. Descriptions are diffed on every release — see version history.
The rules a browser game must follow to run on YouGame (build layout, paths, limits, the runtime sandbox, what usually breaks and how to fix it) plus how to verify and upload. Read this first when making a game YouGame-ready.
No parameter schema on file.
The complete YouGame SDK reference: leaderboards (gameOver / submitScore), beat-my-score links, online multiplayer with matchmaking, friend invites, skill ratings, and coins. One script tag, no account needed.
No parameter schema on file.
Runs YouGame's pre-upload checks on a build folder and returns a verdict: ready, risky (warnings), or broken (the game will not start). Pass every file path in the folder (relative to the folder, forward slashes) and the text of index.html; also pass the text of .html/.css/.js files worth scanning (8 MB of text in total). Fix what it reports and run it again until the verdict is ready, then zip th
No parameter schema on file.
Searches the YouGame documentation (the publish guide and the SDK reference) and returns matching sections with ids. Use it to answer a specific question — how scores are posted, what multiplayer guarantees, what breaks a build — without reading a whole document, then call fetch with an id.
No parameter schema on file.
Returns the full text of one YouGame documentation section by the id search returned (for example "sdk#leaderboards").

Publishes a staged build as a game on YouGame, live at once. Needs the creator's API key. First stage the build: zip the build folder's contents and POST the zip as the raw body to https://yougame.co/api/agent/upload with header "Authorization: Bearer $YOUGAME_API_KEY" (for example: curl -sS -X POST https://yougame.co/api/agent/upload -H "Authorization: Bearer $YOUGAME_API_KEY" -H "Content-Type: a

Ships a new build of a game the creator already published, as its next version: same link, same origin, scores and comments kept. Needs the creator's API key. Stage the new build exactly as for publish_game (zip, POST to https://yougame.co/api/agent/upload, fix what the report calls broken), then call this tool (or POST the same fields to https://yougame.co/api/agent/update) with the game's slug (

The games the API key's creator has published on YouGame: slug, URL, title, version, plays, SDK features. Needs the creator's API key.

What counts against your monthly calls
| Tool | Unit | Calls used | Out of the allowance |
|---|
Nothing here is billable. YouGame costs nothing to install and nothing to call, at any volume.
Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.
This listing is a hosted endpoint: the publisher runs it and we connect to it. The scanner reads packages and source, and neither exists to read here, so there is no grade — not a withheld one, an unmeasured one. What can be checked instead is on Installation: what it asks to reach and what it writes.
Release history
Pinned to 1.0.0 — the install command below asks for that release. A pin is part of an install, so it is kept for this visit and written down when you install.
No release note was published with this version.
One review per account, from a signed-in account that does not publish this listing. Nothing else is asked — you can say what you think before you install it. Publishers can reply once per review, and a review can be edited or deleted by whoever wrote it.
Writing one takes an account with at least 50 real tool calls against YouGame in the last 90 days. That is the whole gate — there is no other way to post, which is why the counts beside each review are worth reading.
Nobody has reviewed this listing. The rating on the card is the mean of the reviews written here and nothing else, so there is no rating until somebody writes the first — which takes an account with 50 real tool calls against it.
