MCP Server Setup

What is the MCP Server?

The Fast Mode MCP (Model Context Protocol) Server connects AI coding assistants like Cursor and Claude Desktop directly to Fast Mode. This means your AI can:

• Build websites that work perfectly with Fast Mode
• Manage your CMS content (create, update, delete items)
• Create collections and fields automatically
• Deploy websites directly to your projects
• Validate templates and manifests as it works

Prerequisites

• Node.js 18+ installed on your computer
• Cursor or Claude Desktop (or another MCP-compatible AI tool)
• A Fast Mode account

Installation for Cursor

Step 1: Open MCP Settings

1. Open Cursor
2. Go to Settings (gear icon or Cmd/Ctrl + ,)
3. Navigate to Features → MCP Servers
4. Click Add new MCP server

Step 2: Add the Configuration

Copy and paste this entire configuration:

{
  "mcpServers": {
    "fastmode": {
      "command": "npx",
      "args": ["-y", "multisite-cms-mcp@latest"],
      "env": {
        "FASTMODE_API_URL": "https://api.fastmode.ai"
      }
    }
  }
}

Step 3: Restart Cursor

Close and reopen Cursor for the changes to take effect.

Installation for Claude Desktop

Step 1: Open Settings

1. Open Claude Desktop
2. Go to Settings → Developer → MCP Servers

Step 2: Add the Configuration

Add the Fast Mode server with this configuration:

{
  "mcpServers": {
    "fastmode": {
      "command": "npx",
      "args": ["-y", "multisite-cms-mcp@latest"],
      "env": {
        "FASTMODE_API_URL": "https://api.fastmode.ai"
      }
    }
  }
}

Step 3: Restart Claude Desktop

Close and reopen Claude Desktop.

First-Time Authentication

The first time your AI uses a Fast Mode tool, you'll need to authenticate:

What Happens

1. Your browser opens to app.fastmode.ai/device
2. A code appears in your AI tool (like "ABCD-1234")
3. Sign in to Fast Mode (if not already)
4. Enter the code and click Authorize
5. Done! Your AI is now connected

Where Credentials Are Stored

After authentication, your credentials are saved to:

~/.fastmode/credentials.json

These refresh automatically, so you won't need to re-authenticate for 90 days.

Verify It's Working

Ask your AI assistant:

"What Fast Mode projects do I have access to?"

If the MCP server is working, it will list your projects. If you see an authentication prompt, follow the steps above.

Alternative: Global Installation

If you prefer to install globally instead of using npx:

npm install -g multisite-cms-mcp

Then use this configuration instead:

{
  "mcpServers": {
    "fastmode": {
      "command": "multisite-cms-mcp",
      "env": {
        "FASTMODE_API_URL": "https://api.fastmode.ai"
      }
    }
  }
}
