What is MCP TypeScript SDK?
The Model Context Protocol (MCP) lets you build servers that expose data and functionality to LLM applications in a secure, standardized way. Think of it like a web API, but specifically designed for LLM interactions.
How to use MCP TypeScript SDK?
Use the SDK to build MCP clients that connect to any MCP server, create MCP servers that expose resources, prompts, and tools, utilize standard transports like stdio and SSE, and handle all MCP protocol messages and lifecycle events. Start by installing the package with npm install @modelcontextprotocol/sdk and follow the quickstart guide to create a simple MCP server.
