modelcontextprotocol/typescript-sdk
Official TypeScript SDK for building and interacting with Model Context Protocol (MCP) servers and clients, enabling standardized context provision for large language models.
wong2/litemcp
LiteMCP is a TypeScript framework designed to facilitate the creation of MCP (Model Context Protocol) servers in an elegant and structured manner. It provides developers with a comprehensive set of features including support for tools, resources, prompts, logging, and SSE (Server-Sent Events) transport, all integrated within a single framework. The framework emphasizes simplicity and full TypeScript support, allowing for clear and type-safe definitions of tools, resources, and prompts. Tools in LiteMCP are executable functions that servers expose to clients and LLMs (Large Language Models) to perform specific actions, such as fetching web content or adding numbers. Resources represent various types of data that the server can provide, including file contents, images, logs, and other binary or text data, each identified by a unique URI. Prompts enable the definition of reusable prompt templates and workflows, facilitating standardized interactions with LLMs. The framework includes built-in logging capabilities with multiple log levels (debug, info, warn, error) to help monitor server activities and errors. It also features built-in error handling and a CLI tool for testing and debugging MCP servers efficiently. LiteMCP supports SSE transport, allowing servers to communicate with clients over server-sent events, enhancing real-time data delivery. Although LiteMCP is deprecated in favor of the official MCP TypeScript SDK, it remains a valuable tool for developers who prefer its CLI commands or want a lightweight framework for MCP server development. The project also provides integration with MCP Inspector for web-based server inspection and debugging. Overall, LiteMCP offers a streamlined and developer-friendly approach to building MCP servers, focusing on modularity, ease of use, and robust support for MCP features.
