/**
* Instantly MCP Server - Official Multi-Transport Implementation
*
* Supports both local and remote usage:
* - Stdio Transport: For Claude Desktop, Cursor IDE, local NPM usage
* - Streaming HTTP Transport: For remote hosting at https://mcp.instantly.ai/mcp
*
* Usage:
* node dist/index.js # stdio mode (default)
* TRANSPORT_MODE=http node dist/index.js # HTTP mode for mcp.instantly.ai
*
* Environment Variables:
* INSTANTLY_API_KEY: Your Instantly.ai API key (required for stdio mode)
* TRANSPORT_MODE: 'stdio' (default) or 'http'
* PORT: HTTP server port (default: 3000)
* NODE_ENV: 'production' for mcp.instantly.ai deployment
*
* Authentication Methods (HTTP mode):
* 1. Header-based (more secure): mcp.instantly.ai/mcp
* - Authorization: Bearer [API_KEY]
* - x-instantly-api-key: [API_KEY]
* 2. URL-based: mcp.instantly.ai/mcp/{API_KEY}
