# MCP Everything Server A comprehensive reference implementation for the [Model Context Protocol](https://modelcontextprotocol.io/) (MCP) that demonstrates all features of the protocol. This server showcases the versatility and extensibility of MCP, demonstrating how it can be used to give Large Language Models (LLMs) secure, controlled access to tools and data sources. This server is built with the [TypeScript MCP SDK](https://github.com/modelcontextprotocol/typescript-sdk). ## Features This server implements a comprehensive set of MCP features including: - **Tools**: Various tools including echo, add, long-running operations, environment variable printing, LLM sampling, and more - **Prompts**: Simple and complex prompts with arguments, resource references, and embedded content - **Resources**: Static resources with pagination support, resource templates, and subscriptions - **Logging**: Configurable logging levels with real-time notifications - **Completions**: Auto-completion for prompt arguments and resource references - **Elicitation**: Interactive user input collection with structured schemas - **Annotations**: Content annotations for priority and audience targeting - **Progress Tracking**: Progress notifications for long-running operations - **Real-time Updates**: Resource update notifications and stderr streaming ## Installation ```bash npm install -g @modelcontextprotocol/server-everything ``` ## Usage ### Standard I/O ```bash mcp-server-everything ``` ### Server-Sent Events (SSE) ```bash npm run start:sse ``` ### HTTP with Streaming Support ```bash npm run start:streamableHttp ``` ## Development 1.
