ember-cli-mcp

Allow MCP clients like Claude Code to run Ember CLI commands directly in your projects.

What is this?

This MCP server lets any MCP client (like Claude Code) execute Ember CLI commands. No more copy-pasting commands or switching between terminals - just ask Claude to run your tests, generate components, or build your app.

Quick Start

With Claude Code

Install globally first:

npm install -g ember-cli-mcp
claude mcp add ember-cli -s user -- ember-cli-mcp

Manual Configuration

If you prefer to configure manually, add to your MCP settings:

{
  "ember-cli": {
    "command": "npx",
    "args": ["ember-cli-mcp"]
  }
}

That's it. Now you can tell Claude: "run my tests" or "generate a component called user-card".

Key Features

Test Filtering

Run specific tests with powerful filtering options:

Option	Description	Example
filter	Filter by test name	"authentication"
module	Filter by module	"Unit | Service"
launch	Browser selection	"Chrome,Firefox"
reporter	Output format	"tap", "dot", "xunit"
server	Keep running	true
silent	Hide output	true

Example:

ember_test({ 
  filter: "authentication",
  module: "Unit | Service",
  cwd: "/path/to/your/project"
})

All Commands

Command	Description
ember_new	Create new apps
ember_serve	Start dev server
ember_build	Build for production
ember_test	Run tests (with filters!)
ember_generate	Generate components, routes, services, etc.
ember_destroy	Remove generated code
ember_install	Install addons
ember_project_info	Get project details
ember_list_addons	See installed addons
ember_list_blueprints	Available blueprints
ember_run_command	Run any Ember CLI command

Every command supports the cwd parameter to work with different projects.

Examples

Ask Claude things like:

• "Run the authentication tests"
• "Generate a TypeScript service called notifications"
• "Build my app for production"
• "What addons are installed?"
• "Start the dev server on port 3000"

Claude will use the MCP server to actually run these commands in your project.

Working with Multiple Projects

Every command accepts a cwd parameter:

// Test project A
ember_test({ 
  filter: "user",
  cwd: "/projects/app-a"
})

// Build project B
ember_build({
  environment: "production",
  cwd: "/projects/app-b"
})

Blueprints

All 40+ Ember blueprints are supported:

Category	Blueprints
Components	component, component-class, component-test, template
Routes	route, controller, route-test, controller-test
Services	service, helper, service-test, helper-test
Data	model, adapter, serializer, transform
Tests	acceptance-test, integration-test, unit-test
Utilities	util, mixin, initializer, instance-initializer
