What it does
This is a reference implementation of an MCP server maintained by the MCP steering group. It demonstrates core MCP protocol features—prompts, resources, and tools—to showcase the capabilities of the Model Context Protocol for extending LLM functionality. Built using the TypeScript MCP SDK, it serves as an educational reference for developers building their own MCP servers and learning how to integrate protocol features.
Who it's for
Developers building MCP servers who want to understand the protocol design and learn from reference implementations. This server is expressly not intended for production use; it is best used as a learning tool and reference for MCP SDK patterns, server architecture, and protocol feature implementation.
Common use cases
- Learning MCP protocol features and capabilities
- Reference for MCP SDK patterns and best practices
- Testing MCP client implementations against a reference server
- Understanding how to structure prompts, resources, and tools in an MCP server
Setup pitfalls
- Reference implementation only—not intended for production use despite extensive feature coverage
- CI tests are currently failing; verify recent commits before relying on functionality or using code as reference
- Standalone execution is not useful; the server must be configured into an MCP client application to function
- Risk class is categorized as high; review the source code before deploying
