This server publishes 1 more address. The block above uses the one we reach during checks; the full list is under Endpoints below, and the author may intend a particular one for your client.

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

game
create_game_draft
Makes a private, unpublished draft of a browser game on Playfrog from static files (HTML5/JavaScript). Nobody can see it or play it, including by direct link, and the response carries no play link because nothing serves the game yet. Covers requests to publish, share, post, put online, put on the internet, or host a browser game someone made, and requests for a link other people can play. 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 claim_url, the one link that publishes the game: publishing requires a free Playfrog account, and the game becomes public only after a person opens that link, signs in or creates an account, and finishes publishing. An unpublished draft is deleted after 7 days. update_game_draft replaces the files of a draft made in this same connector session. 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.
update_game_draft
Replaces the files of a private, unpublished draft made with create_game_draft in this same connector session. Covers requests to change, fix, revise or re-send a game that has not been published yet. It works only in the session that created the draft, and there is no way to recover that: a draft from an earlier session or another client cannot be revised here. What that costs is the ability to revise, not the game. The claim link from the original response keeps working and is still the one link that publishes the game. The draft stays private throughout: nobody can see it or play it, including by direct link, and the response carries no play link. Send the complete set of files again rather than a diff; an index.html at the top level is required, 2.5 MB of files in total. Publishing still requires a free Playfrog account and still happens when a person opens the claim link, signs in or creates an account, and finishes publishing. Revising leaves the 7 day life of a draft unchanged.

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: create_game_draft, update_game_draft. 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 913 ms. The bar chart above shows every period we have measured.
Did Publish ever remove tools?
Yes. publish_game, update_game 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 with the file path 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 913 ms on average, which is faster than 10% 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.
