MCP server for interacting with the Scryfall MTG API
Arcade.fun 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.
What it does
Discover playable browser experiences and manage creator-owned game uploads on Arcade.fun.
Quickstart
# 1 — add it to Claude Code
claude mcp add --scope user --transport http arcade-fun-mcp https://arcade.fun/mcp
# 2 — ask your agent for something these tools do
# list_experiences, create_experience, start_version and 5 more
Arcade.fun costs nothing on mcprush: there is no plan to choose here, no cap to set and nothing mcprush can bill you for.
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: it answers at its publisher’s own address and this marketplace is not in the path. Claude Code registers it in one command; --scope user makes it available in every project. The transport below is http, as the publisher's own manifest declares it.
claude mcp add --scope user --transport http arcade-fun-mcp https://arcade.fun/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.
Every approved experience currently playable on arcade.fun, with the origin games are served from. Needs no credentials.
No parameter schema on file.
Register a new experience and get its manage key. Returns game, key and the first version id. The key is shown only here and controls the listing forever — save it. This creates a draft; upload_build is what sends it for review.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| title | string | yes | What the experience is called, 2 to 60 characters. |
| author | string | yes | The creator name players see, 2 to 30 characters. |
| string | yes | Reviewer contact address. Players never see it. | |
| wallet | string | yes | Solana address that receives this listing's creator trading fees. Every public listing launches with its own coin. |
| tagline | string | no | One line for the cabinet. |
| how | string | no | How to take part: the controls and how to begin. |
| inputs | array | yes | How people interact. At least one. |
| devices | array | no | Devices actually tested. Mobile requires touch, voice or camera among inputs. |
| aspect | string | no | Shape on screen. Empty fills the screen. |
| kind | string | no | 'sdk' if the entry page calls arcade.ready(), otherwise 'web'. Detected from the build too. |
| rights | boolean | yes | Confirm the experience is yours to share, including its art, music and code. |
| terms | boolean | yes | Confirm you agree to the arcade.fun terms and community guidelines. |
Open a new version slot for an experience you already own. The live approved version keeps playing until the new one is reviewed.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| game | string | yes | The 12-character game id. |
| key | string | yes | That game's manage key. |
Send the browser build for a version and publish it. One HTML file, or a zip with index.html at its root. A build that passes the sandbox checks goes live immediately: the result has live: true and the play URL. Otherwise live: false and waiting says why, either a list of things to fix or that this arcade reviews that upload by hand. Also returns file count, size, engine and whether the arca
| Parameter | Type | Required | Notes |
|---|---|---|---|
| version | string | yes | Version id from create_experience or start_version. |
| key | string | yes | The game's manage key. |
| content_base64 | string | yes | The .html or .zip file, base64 encoded. Up to 24 MB decoded. |
| filename | string | yes | The file's name, so the type is read correctly: e.g. index.html or build.zip. |
| entry | string | no | Start page inside a zip, if it is not index.html. |
| threads | boolean | no | True if the build needs SharedArrayBuffer. Threaded builds open in their own tab and cannot use the SDK bridge. Omit to work it out from the files. |
Name the page that starts the experience, when a zip had several and no index.html.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| version | string | yes | — |
| key | string | yes | — |
| entry | string | yes | A path the upload result offered, e.g. game/play.html. |
Upload the square cover used for the cabinet, the sharing card and the coin image. PNG, JPEG, WebP or GIF up to 4 MB.

|---|---|---|---|
| game | string | yes | — |
| key | string | yes | — |
| image_base64 | string | yes | The image, base64 encoded. |
Upload the MP4 played when the experience's link is shared. Without one the platform builds an animated title card from the cover instead.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| game | string | yes | — |
| key | string | yes | — |
| video_base64 | string | yes | The MP4, base64 encoded. |
Where an experience stands: its details, its coin plan, any note from the reviewers, and every version with its status.

- Every tool — any call limit is its publisher’s, not ours
- No card, and mcprush charges nothing for it
- Runs at its publisher’s own address — this marketplace is not in the path
- Nothing to cap, because mcprush bills nothing
What counts against your monthly calls
| Tool | Unit | Calls used | Out of the allowance |
|---|
Nothing here is billable: mcprush charges nothing to install Arcade.fun or to call it, 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.
| Term | Level | What it prices | Points |
|---|---|---|---|
| capability-exposure | moderate | capability blast radius (moderate) — client exposure if the model is manipulated | −3 |
| coverage-honesty | manifest | inspection depth (manifest) — how much of the target the scan could see | −4 |
What the scan could actually read
A grade is only as meaningful as its coverage, so the scanner publishes its own depth before it publishes its result.
The scan read each tool’s name, description, input schema and annotations exactly as the server listed them the last time it answered us; no code was reviewed. We ask the server again about once a month, and a list that changed is graded again.
The implementation source was not read — this reflects the declared tool metadata only.
Capability — what it could do if the model were manipulated
Tags derived from each tool’s schema and the implementation, not from what the tool calls itself. moderate is the level these add up to.
| Tool | Capability tags | Why the tag was assigned |
|---|---|---|
| list_experiences | no tags | |
| create_experience | state-write | state-write: declares readOnlyHint: false |
| start_version | state-write | state-write: declares readOnlyHint: false |
| upload_build | state-write | state-write: declares readOnlyHint: false |
| set_entry | state-write | state-write: declares readOnlyHint: false |
| set_cover | state-write | state-write: declares readOnlyHint: false |
| set_trailer | state-write | state-write: declares readOnlyHint: false |
| experience_status | no tags |
Toxic-flow graph
The lethal trifecta, checked as a graph rather than as a checklist: untrusted input, a sensitive source and an external sink have to meet before there is a path worth worrying about.
The public result for this release does not print the flow graph, so there is nothing to show here. That is not the same as "no paths were found": what the scan did read is above, under coverage.
Supply chain and provenance
This is the first scan of this surface here, so there is nothing yet to compare it against.
Every result on this tab comes from one deterministic pass over the published package — offline, rule by rule, and auditable line by line above. Same methodology version, same bytes, same score.
Release history
This is an address its publisher runs: which release it serves is theirs to choose, so there is nothing here to pin. The history below is for reading; the current release on file is 1.0.0.
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.
Any signed-in account that does not publish Arcade.fun can review it, once — before installing it or after. A review from an account that has installed it is marked as one.
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 a signed-in account that does not publish it, and nothing else.
