MCP - Model Context Protocol
@AdiGo22
MCP Server using TypeScript and JavaScript made with official MCP docs handling US Weather data having context for two tools - showing weather forecast and weather alerts for US based location. Used Zod for data validation and architectured two folders - src and build , developme
Overview
What is MCP - Model Context Protocol?
MCP is an open standard that enables developers to build secure, two-way connections between their data sources and AI-powered tools. It follows a client-server architecture where a host application can connect to multiple servers, allowing developers to either expose their data through MCP servers or build AI applications (MCP clients) that connect to these servers.
How to use MCP - Model Context Protocol?
Developers write TypeScript code in the src/ directory, implementing MCP protocol handlers (Resources, Tools, Prompts), compile it to JavaScript in the build/ directory using the TypeScript compiler, then run it via node build/index.js. Claude Desktop interacts with the server over stdio, where the flow is: Claude Desktop ↔ stdio ↔ Server Transport ↔ McpServer ↔ Tools.
