/llms.txt/openapi.json/api/docs/api/catalog/summary/api/catalog/entries?kind=blocks
Content Model
Most public content is file-based and lives in src/data/contents.
animated-components/: animated component source foldersregistry/: MDX metadata for animated component entriescomponents/: UI component category configsblocks/: block content and previewsdashboards/: dashboard entries and demostemplates/: template entries and demos
Routes are wired in src/components/layout/app-routes.tsx, and the sitemap is generated from the same content model in scripts/generate-sitemap.ts.
Installable Components
Watermelon components are distributed as copy-paste shadcn registry items, so
the resulting code lives in the consuming project and remains fully editable.
npx shadcn@latest add https://registry.watermelon.sh/r/card-split-accordian.json
The registry is generated from the maintained animated component source during
every platform build and includes the complete base-component collection.
Connect the hosted MCP server (no API key) to your AI client:

AI And Developer Surfaces
Watermelon includes a few machine-readable surfaces to help agents and tooling understand the project faster:

The hosted MCP endpoint lives at https://mcp.watermelon.sh/mcp and exposes
800+ source-backed examples through search, retrieval, inspiration, category,
and page-composition tools.
The hosted Worker records aggregate initialize and tools/call event counts
in Cloudflare Analytics Engine. It does not retain IP addresses, session IDs,
prompts, tool arguments, or client-provided versions.
