Installation

# Install dependencies
bun install

# Build the server
bun run build

Authentication

The server supports two authentication methods:

HTTP Transport (Recommended)

Pass your API key as a Bearer token in the Authorization header:

curl -X POST http://localhost:3000/mcp \
  -H "Authorization: Bearer your_platform_api_token" \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","method":"tools/list","id":1}'

stdio Transport

Set the CLERK_PLATFORM_API_KEY environment variable:

export CLERK_PLATFORM_API_KEY=your_platform_api_token

Usage

HTTP Mode (Remote/Multi-client)

# Start server on default port 3000
bun run start:http

# Start server on custom port
bun run dist/index.js --http --port 8080

stdio Mode (Local Integrations)

# With environment variable
CLERK_PLATFORM_API_KEY=your_token bun run start

# Or just start (will prompt for auth on first tool use)
bun run start

Development Mode

# HTTP with auto-reload
bun run dev:http

# stdio with auto-reload
bun run dev

With Cursor/Claude Desktop

For HTTP transport (recommended for remote access):

{
  "mcpServers": {
    "clerk-platform": {
      "url": "http://localhost:3000/mcp",
      "headers": {
        "Authorization": "Bearer your_platform_api_token"
      }
    }
  }
}

For stdio transport (local):

{
  "mcpServers": {
    "clerk-platform": {
      "command": "bun",
      "args": ["run", "/path/to/clerk-platform-mcp-server/dist/index.js"],
      "env": {
        "CLERK_PLATFORM_API_KEY": "your_platform_api_token"
      }
    }
  }
}

Command Line Options

Usage:
  clerk-platform-mcp-server [options]

Options:
  --http         Use HTTP transport (default: stdio)
  --port <port>  Port for HTTP server (default: 3000)
  --help, -h     Show help message

Example Workflows

Creating a New Application

1. Use clerk_create_application with name="My App" and template="b2b-saas"
2. The response includes application_id and instance details with keys

Setting Up a Custom Domain

1. Use clerk_update_application_domain to set domain name
2. Configure CNAME records from the response
3. Use clerk_trigger_dns_check to verify configuration
4. Use clerk_get_application_domain_status to monitor progress

Transferring an Application

1. Use clerk_create_application_transfer to initiate transfer
2. Share the transfer code with the recipient workspace
3. Recipient claims the transfer using the code
4. Use clerk_get_application_transfer to check status
