Server details

Identifier: sh.watermelon/ui
Transport: Streamable HTTP
Runtime: Web executable
Trust: Verified
Published: Sep 30, 2026

Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified that this server's namespace belongs to watermelon.sh, which also runs its endpoint. That identifies the publisher; it does not make the server's tools safe.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

Watermelon UI lets an assistant search a catalog of free React, Tailwind and shadcn components, blocks and dashboards and retrieve installable source.

What you can do: Search the catalog across components, animated components, blocks, dashboards and templates, and list categories with entry counts or top-level catalog totals. Retrieve a single entry with its preview, dependencies, install command and source files when an installable registry item exists. Get a short set of visually relevant options for a design goal before committing to an implementation. Compose a source-backed page plan by picking compatible blocks for each requested section. Look up entries by kind and slug through compatibility aliases.
When to use it: Useful when building React interfaces with Tailwind and shadcn and you want the assistant to find ready-made components, blocks or dashboards, compare design options, or assemble a page plan from existing blocks instead of writing everything from scratch.
Requirements: A remote streamable HTTP endpoint; no package, environment variable or header is declared. The manifest declares no authentication.

Before you install

The catalog is third-party content, so review retrieved source files and install commands before running them in your project. The server is described as read-only lookup and planning; it does not appear to write to your codebase itself.

Installation

In SourceWeft

Open Watermelon UI in the dashboard and add it to a workspace.
Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/sh.watermelon%2Fui/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

85% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
