MCP TypeScript SDK  
AI SummaryThe MCP TypeScript SDK is a comprehensive toolkit for building and integrating Model Context Protocol servers and clients in TypeScript applications. Developers building AI-powered tools, Claude integrations, or context-aware LLM applications benefit from its standardized approach to managing resources, tools, and prompts.

Copy this and paste it into Claude Code, Cursor, or any AI assistant:
I want to set up the "MCP TypeScript SDK  " agent in my project. Please run this command in my terminal: # Add AGENTS.md to your project root curl --retry 3 --retry-delay 2 --retry-all-errors -o AGENTS.md "https://raw.githubusercontent.com/rakeshgangwar/30Days30Agents/main/agents/Day-11-Recipe-Generator/mealie-mcp-server/docs/MCP.md" Then explain what the agent does and how to invoke it.
Description
- [Overview](#overview)
Overview
The Model Context Protocol allows applications to provide context for LLMs in a standardized way, separating the concerns of providing context from the actual LLM interaction. This TypeScript SDK implements the full MCP specification, making it easy to: • Build MCP clients that can connect to any MCP server • Create MCP servers that expose resources, prompts and tools • Use standard transports like stdio and Streamable HTTP • Handle all MCP protocol messages and lifecycle events
Tools
Tools let LLMs take actions through your server. Unlike resources, tools are expected to perform computation and have side effects: `typescript // Simple tool with parameters server.tool( "calculate-bmi", { weightKg: z.number(), heightM: z.number() }, async ({ weightKg, heightM }) => ({ content: [{ type: "text", text: String(weightKg / (heightM * heightM)) }] }) ); // Async tool with external API call server.tool( "fetch-weather", { city: z.string() }, async ({ city }) => { const response = await fetch(https://api.weather.com/${city}); const data = await response.text(); return { content: [{ type: "text", text: data }] }; } ); `
