Overview

AI-generated overview

Lets an assistant search free React, Tailwind, and shadcn UI components, blocks, and dashboards and retrieve installable source.

What it does
Watermelon UI is a remote MCP server that exposes a searchable catalog of free React, Tailwind, and shadcn components, blocks, and dashboards. Through the assistant, it returns matching entries and the installable source for them, so UI pieces can be found and pulled into a project without browsing a site manually. The manifest lists no tools, so the exact tool names and parameters are not documented here.
When to use it
Useful when building or extending a React interface with Tailwind and shadcn and you want the assistant to locate ready-made components, blocks, or dashboard layouts and hand back source you can install. Less relevant if your stack is not React, Tailwind, or shadcn.
Requirements
A remote MCP endpoint at mcp.watermelon.sh over streamable HTTP; no packages, environment variables, or headers are declared. The manifest declares no authentication, and network access to the endpoint is needed.
Before you install
The manifest declares no authentication, so requests to the remote endpoint are not tied to a declared credential. Source returned by the server is third-party code; review it before installing or running it in a project. No write, payment, or secret-handling behavior is described in the available input.
