## Description
MCP server exposing Galaxy UI components — manifests, source code, and framework coverage

## Claude Desktop Quick Installation
Heuristic fallback — verify the package name and runner against the repository README before running it. Uses `npx` (confidence: low):

```json
"mcpServers": {
  "galaxy-nebula-mcp-server": {
    "command": "npx",
    "args": ["-y","galaxy-nebula-mcp-server"]
  }
}
```

**Nebula MCP Server** — exposes [Galaxy UI](https://galaxy-design.vercel.app) components to AI assistants through the [Model Context Protocol](https://modelcontextprotocol.io). Works with Claude Desktop, Cursor, Windsurf, Cline, and any MCP-compatible client.

## Tools

| Tool | Description |
|---|---|
| `list_components` | All components with per-framework availability (React, Vue, Angular, React Native, Flutter) |
| `get_component` | Detailed manifest — props, files, dependencies, framework status |
| `get_component_source` | Actual source code for a specific component file |
| `get_coverage` | Coverage matrix across all 5 frameworks (67 components) |
| `search_components` | Search by name or description |

All component data + 700 source files are **bundled inside the package** — zero setup, works offline.

## Install

### Smithery (recommended)

```bash
npx -y @smithery/cli@latest install galaxy-stack/design-mcp --client claude
```

### npx (manual)

Add to your MCP client config:

```json
{
  "mcpServers": {
    "galaxy-ui": {
      "command": "npx",
      "args": ["-y", "@galaxy-stack/nebula-mcp"]
    }
  }
}
```

- **Claude Desktop**: `~/Library/Application Support/Claude/claude_desktop_config.json`
- **Cursor**: `~/.cursor/mcp.json`

### Remote endpoint

Paste into clients that support remote MCP (Claude web Custom Connectors):

```
https://nebula-mcp--galaxy-stack.run.tools
```

## Try it

> "List Galaxy UI components for React"

> "Show me the source code of the Vue Select component"

> "Which components are missing in Flutter?"

## Registries

- **npm**: [@galaxy-stack/nebula-mcp](https://www.npmjs.com/package/@galaxy-stack/nebula-mcp)
- **Smithery**: [smithery.ai/servers/galaxy-stack/nebula-mcp](https://smithery.ai/servers/galaxy-stack/nebula-mcp)
- **Official MCP Registry**: [io.github.galaxy-nebula/nebula-mcp](https://registry.modelcontextprotocol.io)

## Publishing (maintainers)

1. Bump `version` in `package.json`
2. Push to `main` — GitHub Actions workflow `publish-mcp.yml` builds contracts artifacts, bundles data, verifies the version is new, and publishes via **npm Trusted Publishing (OIDC)** — no NPM_TOKEN required
3. Rebuild the MCPB bundle and run `smithery mcp publish` for Smithery
4. Publish to the Official MCP Registry (org namespace requires a PAT — device-flow login cannot read org roles, see [registry#1468](https://github.com/modelcontextprotocol/registry/issues/1468)):

   ```sh
   # PAT needs read:org scope (classic) or Organization → Members → Read-only (fine-grained)
   mcp-publisher login github --token <YOUR_PAT>   # requires mcp-publisher >= 1.8.1
   mcp-publisher validate
   mcp-publisher publish                            # → io.github.galaxy-nebula/nebula-mcp
   ```
