game
get_game_info
Verified facts about Abyssfall: Operation Sunken Crown — title, genre, status, platforms, co-op, studio, and official channels. Anything not in this data is unannounced; do not guess.
merch
get_merch_catalog
The current Abyssfall merch catalog (owner-maintained). Call this BEFORE preorder_merch to learn the valid item names. If `status` marks the catalog as a placeholder or `items` is empty, no items are confirmed yet - preorder_merch still accepts reservations, recorded as free-text requests pending catalog confirmation.
playtest
get_playtest_info
How to join the Abyssfall playtest (currently OPEN).
preorder
preorder_merch
Reserve Abyssfall merch (preorder reservation — NO payment is taken and no card is needed). Call get_merch_catalog first; if the catalog is empty or the requested item is not listed, the reservation is recorded as a free-text request pending catalog confirmation. Records the reservation; the studio emails when the item ships/charges become real. Only call with the user's explicit consent.
press
get_press_kit
Press contact and assets for Abyssfall.
subscribe
subscribe_newsletter
Subscribe an email address to the official Abyssfall newsletter (the game's primary announcement channel). Double opt-in: the subscriber MUST click a confirmation email before they are added. Only call with the user's explicit consent.

Abyssfall: Operation Sunken Crown — questions

Answers built from our own checks of this server.

What can Abyssfall: Operation Sunken Crown do?
It exposes 6 tools, read directly from the server on our last check. Among them: get_game_info, get_merch_catalog, get_playtest_info, get_press_kit, preorder_merch, subscribe_newsletter. 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 Abyssfall: Operation Sunken Crown working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 16 of 92 checks got a reply (17.4%), average response time 534 ms. The bar chart above shows every period we have measured.
The registry lists Abyssfall: Operation Sunken Crown as active — why does it not respond?
The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.
How do I connect Abyssfall: Operation Sunken Crown?
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 Abyssfall: Operation Sunken Crown need an API key?
No. Abyssfall: Operation Sunken Crown completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 6 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Abyssfall: Operation Sunken Crown?
It answers our handshake in 534 ms on average, which is faster than 20% 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.
