Angular CLI MCP Server
The Angular CLI includes a Model Context Protocol (MCP) server that enables AI assistants (like Cursor, Gemini CLI, JetBrains AI, etc.) to interact directly with the Angular CLI. It provides tools for project analysis, guided migrations, and running builds/tests.
Available Tools (Default)
When the MCP server is enabled, AI agents have access to the following tools:
| Name | Description |
|---|---|
ai_tutor |
Launches an interactive AI-powered Angular tutor. |
get_best_practices |
Retrieves the Angular Best Practices Guide (crucial for standalone components, typed forms, etc.). |
list_projects |
Lists all applications and libraries in the workspace by reading angular.json. |
onpush_zoneless_migration |
Analyzes code and provides a plan to migrate it to OnPush change detection (prerequisite for zoneless). |
search_documentation |
Searches the official documentation at https://angular.dev. |
Experimental Tools
Some tools must be enabled explicitly using the --experimental-tool (or -E) flag.
| Name | Description |
|---|---|
build |
Performs a one-off build using ng build. |
devserver.start |
Asynchronously starts a dev server (ng serve). Returns immediately. |
devserver.stop |
Stops the dev server. |
devserver.wait_for_build |
Returns the logs of the most recent build in a running dev server. |
e2e |
Executes end-to-end tests. |
test |
Runs the project's unit tests. |
Configuration
To use the MCP server, you configure your host environment (IDE or CLI) to run npx @angular/cli mcp.
Antigravity IDE
Create a file named .antigravity/mcp.json in your project's root:
{
"mcpServers": {
"angular-cli": {
"command": "npx",
"args": ["-y", "@angular/cli", "mcp"]
}
}
}
Gemini CLI
Create .gemini/settings.json in the project root:
{
"mcpServers": {
"angular-cli": {
"command": "npx",
"args": ["-y", "@angular/cli", "mcp"]
}
}
}
Cursor
Create .cursor/mcp.json in the project root (or globally at ~/.cursor/mcp.json):
{
"mcpServers": {
"angular-cli": {
"command": "npx",
"args": ["-y", "@angular/cli", "mcp"]
}
}
}
VS Code
Create .vscode/mcp.json:
{
"servers": {
"angular-cli": {
"command": "npx",
"args": ["-y", "@angular/cli", "mcp"]
}
}
}
Command Options
You can pass arguments to the MCP server in the args array of your configuration:
--read-only: Only registers tools that do not modify the project.--local-only: Only registers tools that do not require an internet connection.--experimental-tool(-E): Enables specific experimental tools (e.g.,-E build,-E devserver).
Example for read-only mode with experimental tools enabled:
"args": ["-y", "@angular/cli", "mcp", "--read-only", "-E", "build", "-E", "test"]
