Today is the operative word: we check Sundae UI every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Available tools 9

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

component

get_component

Full documentation for one asset: description, when to use it, props, variants (tweakable options), keyboard support, accessibility, dependencies, usage example and free/pro status.

get_component_source

Returns the source files for an asset, to be written under components/sundae/. Free assets need no auth. Pro assets require an API token for an account with active Sundae Pro; the entitlement is checked on the server for every call.

account

get_account

Whether this MCP connection is authenticated and has Sundae Pro. Never returns personal data beyond that.

browse

browse_category

List the assets in one category, newest first, optionally only free or only pro.

Sundae UI — questions

Answers built from our own checks of this server.

What can Sundae UI do?

It exposes 9 tools, read directly from the server on our last check. Among them: browse_category, find_related, get_account, get_component, get_component_source, get_install_instructions and 3 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 Sundae UI working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 298 ms. The bar chart above shows every period we have measured.

How do I connect Sundae UI?

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 Sundae UI need an API key?

No. Sundae UI completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 9 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Sundae UI?

It answers our handshake in 298 ms on average, which is faster than 46% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
