Watermelon UI Auth Docs

Watermelon UI currently exposes public, read-only developer surfaces that do not require authentication. Agents and engineers can access the public docs, catalog endpoints, and hosted MCP discovery routes without bearer tokens, session cookies, or account login flows.

No-auth surfaces

Public API

The current public HTTP API is read-only. It supports summary, listing, and single-entry lookup endpoints for the Watermelon catalog. Responses include structured JSON errors, versioning headers, deprecation headers on compatibility aliases, and rate-limit headers for self-throttling clients.

MCP

The hosted Watermelon MCP server is also read-only and currently unauthenticated. It is intended for structured catalog access, not private account actions or repository mutation.

Open-source UI platform for developers

Watermelon UI is an open-source platform for browsing React components, animated interactions, dashboards, templates, and reusable page sections. The project is built for the community and helps developers move from inspiration to implementation faster by pairing visual previews with source-backed examples and documentation. The platform also includes full templates so people can see how individual blocks work together as realistic product pages instead of only as isolated snippets.

Important public pages include the main docs home, animated components, blocks, dashboards, templates, developer docs, about, contact, privacy, terms, copyright, llms.txt, and the sitemap. The repositories under WatermelonCorp are the source of truth for contributions, and the platform repository includes local MCP tooling for structured agent access to the catalog.
