Key features

  1. 01List components and framework availability
  2. 02Inspect component manifests
  3. 03Retrieve component source files
  4. 04View framework coverage
  5. 05Search by component name or description
  6. 06Bundled data works offline

Use cases

  1. 01Finding components available in a framework
  2. 02Checking component props and dependencies
  3. 03Retrieving source for a UI component
  4. 04Identifying framework coverage gaps

MCP support

Exposes Galaxy UI component listings, manifests, source code, coverage, and search as tools for MCP clients.

Configuration

Local server config is the same for every client. Copy it into your client’s MCP config file.

mcp.json · Universal config
{
  "mcpServers": {
    "galaxy-nebula-nebula": {
      "command": "npx",
      "args": [
        "-y",
        "@galaxy-stack/nebula-mcp"
      ]
    }
  }
}
Run commandnpx -y @galaxy-stack/nebula-mcp

Local servers need a runtime on your machine (e.g. Node.js 18+). Config file locations differ by client; see your client’s docs.

Nebula MCP Server — exposes Galaxy UI components to AI assistants through the Model Context Protocol. Works with Claude Desktop, Cursor, Windsurf, Cline, and any MCP-compatible client.

Tools

ToolDescription
list_componentsAll components with per-framework availability (React, Vue, Angular, React Native, Flutter)
get_componentDetailed manifest — props, files, dependencies, framework status
get_component_sourceActual source code for a specific component file
get_coverageCoverage matrix across all 5 frameworks (67 components)
search_componentsSearch by name or description

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

Install

Smithery (recommended)
npx -y @smithery/cli@latest install galaxy-stack/design-mcp --client claude
npx (manual)

Add to your MCP client config:

{
  "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

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):

    # 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

New to MCP?

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
