Angular Toolkit MCP

A Model Context Protocol (MCP) server that provides Angular project analysis and refactoring capabilities. This server enables LLMs to analyze Angular projects for component usage patterns, dependency analysis, code quality issues, and provides automated refactoring assistance.

Installation

No installation required! Run directly with npx:

``bash
npx @push-based/angular-toolkit-mcp@latest --workspaceRoot=/path/to/workspace --ds.uiRoot=packages/ui
`

Configuration

Add the server to your MCP client configuration (e.g., Claude Desktop, Cursor, Copilot, Windsurf):

`json
{
"mcpServers": {
"angular-toolkit": {
"command": "npx",
"args": [
"@push-based/angular-toolkit-mcp@latest",
"--workspaceRoot=/absolute/path/to/your/angular/workspace",
"--ds.uiRoot=packages/ui",
"--ds.storybookDocsRoot=storybook/docs",
"--ds.deprecatedCssClassesPath=design-system/component-options.mjs"
]
}
}
}
`
