Available tools 2

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

game
update_game
Publish a new version of an existing Playfrog game at the same play link. Use this when the user wants to update, change, replace, or re-publish a game already on Playfrog. Requires the game_id and manage_token returned by publish_game. Send the complete set of files again, not a diff. Returns the new version_id and the same play_url.
publish
publish_game
Publish a browser game (HTML5/JavaScript, static files) to Playfrog and get a public, shareable play link in seconds. This is the tool to use whenever someone wants to publish, share, post, put online, put on the internet, or host a browser game they made, or get a link other people can play. Free, no account and no API key. Send the game files; an index.html at the top level is required, 2.5 MB of files in total. An optional cover image improves the game page and social share card. Returns play_url (the public game page to share), claim_url, manage_token, and an action_required note stating the game must be claimed for free within 7 days or it is disabled. Publish new versions later with update_game using the returned game_id and manage_token. Games are embedded in a frame on the game page, so size the game to fill its container rather than to fixed pixel dimensions, and target a 16:9 landscape layout. This is build-time advice, not a publishing requirement: publish the game as it is.

Publish — questions

Answers built from our own checks of this server.

What can Publish do?
It exposes 2 tools, read directly from the server on our last check. Among them: publish_game, update_game. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Publish working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 182 of 182 checks got a reply (100.0%), average response time 824 ms. The bar chart above shows every period we have measured.
Did Publish ever remove tools?
Yes. create_game_draft, update_game_draft are no longer exposed — we recorded the date each one disappeared. A tool vanishing usually means a breaking change for anything that depended on it.
How do I connect Publish?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Publish need an API key?
No. Publish completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 2 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Publish?
It answers our handshake in 824 ms on average, which is faster than 8% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
