What changed 7

Every tool that appeared, vanished or quietly changed what it asks for. Recorded since 3 September 2026. No other catalogue keeps this.

3 Sep 7 tools changed the parameters they ask for browse, card_of_the_day, find_variants and 4 more

Cards missed 2 checks this week

Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.

Cards — questions

Answers built from our own checks of this server.

What can Cards do?
It exposes 7 tools, read directly from the server on our last check. Among them: browse, card_of_the_day, find_variants, get_card, get_set_checklist, identify_card and 1 more. 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 Cards working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 90 of 91 checks got a reply (98.9%), average response time 502 ms. The bar chart above shows every period we have measured.
How do I connect Cards?
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 Cards need an API key?
No. Cards completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 7 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Cards?
It answers our handshake in 502 ms on average, which is faster than 30% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
