What can the tools do?

Five tools: list_resources, get_resource, get_snippet, search and get_lab. Your agent can browse the catalog, read full metadata, pull real code snippets and open live demos.

Is it remote or local?

claude.ai and Claude Desktop connectors are remote — they call https://mcp.stealthis.dev/mcp directly. Local development uses http://localhost:8787/mcp.

Model Context Protocol

2,000+ UI resources for your AI agent.

Q: Do I need an API key?

No. The Stealthis MCP server is free and public — just add the URL, no authentication required.

Q: Which clients are supported?

Anything that speaks MCP Streamable HTTP: claude.ai (web), Claude Desktop, Claude Code, Cursor and other MCP clients.

One URL. Free. No API key. Claude, Claude Code and Cursor can search, read and drop Stealthis components, pages and design systems into a project.

Custom connector

Remote — nothing runs on your machine.

Copy https://mcp.stealthis.dev/mcp.
Open Settings → Connectors → Add custom connector.
Name it Stealthis, paste the URL, click Add. The five tools show up in every chat.

Terminal

Claude Code

One command registers the server for every session.

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

Then put this in CLAUDE.md so the agent searches the library before writing UI from scratch:

Before writing any UI component from scratch, search the stealthis MCP server (tools: search, get_snippet) and adapt it to our design tokens.

mcp.json

Cursor

Add the HTTP server to your MCP config.

{
  "mcpServers": {
    "stealthis": {
      "type": "http",
      "url": "https://mcp.stealthis.dev/mcp"
    }
  }
}

Development

Remote by default, local if you hack on it

claude.ai always uses the hosted Worker. Run the worker yourself only when developing it:

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