@galaxy-stack/nebula-mcp

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

| 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.

Registries

• npm: @galaxy-stack/nebula-mcp
• Smithery: smithery.ai/servers/galaxy-stack/nebula-mcp
• Official MCP Registry: io.github.galaxy-nebula/nebula-mcp

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
