Overview
This server demonstrates how to build custom tools (arithmetic, weather) that can be integrated with Model Context Protocol (MCP) clients like Claude Desktop.
Installation
node mcp.jsSecurity Notes
The server uses Zod for robust input validation for all registered tools, significantly mitigating common injection risks. Network requests for the weather tool are confined to the official Open-Meteo API. No hardcoded secrets, direct 'eval' usage, or code obfuscation were identified in the provided source. Communication over stdio primarily limits direct external network attack surface for the server process itself.
