MCP server

claude mcp add ngwr -- npx -y -p ngwr ngwr-mcp

Or add this to the client's config file:

{
  "mcpServers": {
    "ngwr": {
      "command": "npx",
      "args": ["-y", "-p", "ngwr", "ngwr-mcp"]
    }
  }
}

Client	Config file
Claude Code	`.mcp.json` in the project root
Claude Desktop, macOS	`~/Library/Application Support/Claude/claude_desktop_config.json`
Claude Desktop, Windows	`%APPDATA%\Claude\claude_desktop_config.json`
Cursor	`.cursor/mcp.json` in the project, or `~/.cursor/mcp.json`

Restart Claude Desktop after you edit its config.

{
  "mcpServers": {
    "ngwr": {
      "command": "node",
      "args": ["./node_modules/ngwr/mcp/server.js"]
    }
  }
}

The path is relative to where the client starts the server: the project root for Claude Code.

`search_ngwr`	`query`, `limit` (10, at most 40)	Matching entry points with import line and selector. Start here.
`get_ngwr_component`	`name`: entry point, symbol or selector	Selectors, exports, import line, `@use` line and docs URLs
`get_ngwr_api`	`symbol`: a class or a function, `kind` to narrow a class (`input`, `output`, `method`, …)	Inputs, models, outputs and methods of one class, or the signature of one function (`provideWr`, a `with*()` feature)

It reads only its own package: no network, no writes, and it never runs the commands it returns.
