/**
* Exa AI Web Search MCP Server
*
* This MCP server integrates Exa AI's search capabilities with Claude and other MCP-compatible clients.
* Exa is a search engine and API specifically designed for up-to-date web searching and retrieval,
* offering more recent and comprehensive results than what might be available in an LLM's training data.
*
* The server provides tools that enable:
* - Real-time web searching with configurable parameters
* - Company research and analysis
* - Web content crawling
* - LinkedIn search capabilities
* - Deep research workflows
* - And more!
*
* This is the Smithery CLI entry point. For Vercel deployment, see api/mcp.ts
