claude.ai · Claude Desktop

Add as a custom connector

Remote connector — nothing to install. Works on claude.ai (web) and the Claude desktop app.

  1. Copy the server URL https://mcp.stealthis.dev/mcp.
  2. Open Settings → Connectors → Add custom connector.
  3. Name it Stealthis, paste the URL, click Add. Done — the tools appear in every chat.
Claude Add custom connector modal with the name Stealthis and URL https://mcp.stealthis.dev/mcp filled in
claude.ai → Connectors → Add custom connector
Find components

Search the library from chat

Ask in plain language — the agent calls search and get_snippet behind the scenes.

Prompt
"Search stealthis for a pricing table with a monthly/annual toggle and add it to my landing page."
search → get_snippet
Prompt
"List stealthis resources in the web-animations category that use GSAP, easy difficulty."
list_resources
Prompt
"Show me stealthis dark-theme hero sections and paste the HTML of the best one."
search → get_snippet(html)
Claude Code

One command in your terminal

Registers the server for every Claude Code session.

terminal
$ claude mcp add stealthis --transport http https://mcp.stealthis.dev/mcp

Build pages

Assemble full pages from real snippets

The library ships complete landing pages per industry — gym, clinic, fintech, agency, and 60+ more verticals.

Prompt
"Build a gym landing page using stealthis snippets: hero, class schedule, pricing and a signup modal."
search → get_resource → get_snippet ×4
Prompt
"Create a design-system starter for my brand based on stealthis theme resources — tokens, buttons, cards, forms."
list_resources → get_snippet
Local development

Remote by default, local if you hack on it

The hosted server is what claude.ai and Desktop connectors use — nothing runs on your machine. If you're developing the worker itself, run it locally and point a local client at it:

terminal
$ bun run dev:mcp
# → http://localhost:8787/mcp

Prefer plain HTTP? The same tools exist as REST routes (GET /tools/…) and a machine summary at GET /api.

Live demos

Preview before you steal

Every resource with a demo has a full-screen page on lab.stealthis.dev — the agent fetches the link with get_lab.

Prompt
"Find three stealthis glassmorphism cards, give me their live demo links so I can compare, then install my favorite."
search → get_lab ×3 → get_snippet

FAQ

Do I need an API key or account?
No. The server is free and public. Add the URL and start prompting.
Which clients are supported?
Any MCP client that speaks Streamable HTTP: claude.ai (web), Claude Desktop, Claude Code, Cursor, and others. There's also a plain REST API (GET /tools/…) and a machine-readable summary at GET /api.
What exactly do the five tools return?
list_resources and search return catalog metadata; get_resource returns full details for one slug; get_snippet returns real source code (html, css, js, react, next, vue, svelte, astro); get_lab returns a live full-screen demo URL.
Is this remote or does it run on my machine?
Remote — it's a Cloudflare Worker at mcp.stealthis.dev. claude.ai connectors always use the remote URL. Local (http://localhost:8787/mcp) only applies when you run the worker yourself during development.
Where does the content come from?
Everything in the Stealthis library — 2,000+ MIT-licensed resources, each with docs on stealthis.dev and live demos on lab.stealthis.dev.
