@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.

Official MCP Registry: io.github.galaxy-nebula/nebula-mcp

Publishing (maintainers)

Bump version in package.json
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
Rebuild the MCPB bundle and run smithery mcp publish for Smithery

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
