What it does

Sundae UI is an MCP server, a connector that lets an AI assistant use it as a tool. It is hosted: an assistant connects to it over the internet, nothing to install.

No capability identified yet from its description.

Facts come from the Official MCP Registry, as declared by the publisher. Capabilities are matched automatically (low confidence). None of this is a test of the tool.

9 tools offered to AI assistants

  • search_components · Search Sundae UI by keyword, optionally filtered by category and tier. Returns metadata and install commands, never source.
  • list_categories · All Sundae categories with descriptions and how many assets each holds.
  • browse_category · List the assets in one category, newest first, optionally only free or only pro.
  • 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_usage_example · The usage example and props table for one asset. Available for free and pro assets.
  • get_install_instructions · How to install one asset: target directory, shadcn command, dependencies, styling requirements and whether Pro is needed.
  • 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.
  • find_related · Assets related to one asset (same category, shared tags or art direction), each marked free or pro.
  • get_account · Whether this MCP connection is authenticated and has Sundae Pro. Never returns personal data beyond that.

What "online" means: the server answered an MCP connection at the time of the check. It is not a guarantee of security, quality or continuous uptime. How we test: we open an MCP session and ask for the tool list, as an AI assistant would. We never run a tool and never send a key. Checked every few days. Method

Is this your server? Monitoring Pro: a check every 30 minutes and an email within the hour when it stops answering. Launch offer: $39.99 once, for life.
