Galaxy Nebula MCP Server
MCP server exposing Galaxy UI components — manifests, source code, and framework coverage
Runs on your machine from its package; the steps are below.
What it does
- Reads
- Writes
- High impact
At most: only reads or looks up information.
What it costs
FreeOdel charges nothing per call. The publisher may charge for its own service.
Runs locally over stdio
This server isn't hosted — your MCP client launches it from a package registry. Use one of the commands below, or drop the config into your client (e.g. Claude Desktop).
Run
npx -y @galaxy-stack/nebula-mcp
MCP client config
{
"mcpServers": {
"galaxy-nebula-mcp-server": {
"command": "npx",
"args": [
"-y",
"@galaxy-stack/nebula-mcp"
]
}
}
}@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.
