Faber MCP Server

MCP (Model Context Protocol) server for deploying Laravel applications to Faber servers directly from Cursor.

Overview

Faber MCP enables you to deploy and manage Laravel applications on Faber servers using AI agents in Cursor. Simply ask your AI assistant to "deploy this project to production" and it handles the rest - including provisioning new stacks, managing GitHub deploy keys, and triggering deployments.

Features

• Deploy Laravel apps from Cursor with natural language commands

• Available globally across all your projects

• Multi-server support (production, staging, etc.)

• Automatic GitHub deploy key setup via Device Flow OAuth

• Full stack management (apps, domains, databases, SSL)

• Release management and rollbacks

• Real-time logs and debugging

Installation

Option 1: Install from npm (when published)

Option 2: Install from source

Configuration

Step 1: Create Server Configuration

Create ~/.faber-mcp.json with your Faber server details.

You can copy example-config.json as a starting point:

Or create it from scratch:

Requirements:

• SSH key must have access to the Faber server

• faber CLI must be installed on the server

• You must be able to authenticate as root

Step 2: Configure Cursor

Edit ~/.cursor/mcp.json (create if it doesn't exist):

Alternative configurations:

If Cursor can't find the global command, use the full path:

Or use npx (no global install needed):

Important: Restart Cursor completely after adding the MCP server configuration.

Usage Examples

Deploy Current Project

Simply ask Cursor's AI agent:

"Deploy this project to production"

The agent will:

1. Check if the app already exists on the server

2. If not, prompt you for:

   • Project name (username in Faber)

   • Git repository URL

   • Domain name

   • PHP version

   • Git branch

3. Create the full stack (app, domain, database, SSL, .env)

4. GitHub Authorization (if GitHub OAuth is configured on server):

   • Cursor will display a message like:

     GitHub Authorization Required 1. Open: https://github.com/login/device 2. Enter code: A1B2-C3D4 Waiting for authorization...

   • Click the verification URI and enter the code

   • Authorize the application in your browser

   • Server automatically adds the deploy key to your repository

5. Or if the app exists, trigger a deployment

Other Commands

"Check if myapp is deployed on production"

"List all apps on the production server"

"Rollback myapp to the previous release"

"Show me the production server status"

"Deploy this to staging server"

Multi-Server Support

When using multiple servers, specify which one:

"Deploy this to staging server"

The agent will use the staging profile from your config. If not specified, it uses defaultServer.

• faber_app_logs - View Laravel application logs

Environment

• faber_get_env - Read .env file (read-only)

• faber_set_env_var - Set a specific .env variable

Troubleshooting

MCP server not connecting

• Verify SSH key has access: ssh -i ~/.ssh/id_rsa root@your-server.com

• Check ~/.faber-mcp.json syntax is valid JSON

• Ensure faber CLI is installed on the server: ssh root@server "which faber"

Cursor not recognizing tools

• Restart Cursor completely after adding MCP config

• Check Cursor's MCP logs: View → Output → Select "MCP" from dropdown

• Verify the path in ~/.cursor/mcp.json is correct and absolute

SSH connection errors

• Test SSH connection manually first

• Ensure SSH key permissions: chmod 600 ~/.ssh/id_rsa

• Check server firewall allows SSH on port 22

Faber commands failing

• Verify you're running as root on the server

• Check Faber is installed: ssh root@server "faber version"

• Review server logs: ssh root@server "faber logs"

Requirements

• Node.js 18+ (for running the MCP server locally)

• SSH access to Faber server(s)

• Faber CLI installed on target server(s)

• Cursor IDE with MCP support
