Educational reference implementations demonstrating MCP features and SDK usage; the README warns they are not production-ready. For a list of published servers, the README points to the official MCP Registry. Many older servers (GitHub, Brave Search, GitLab, etc.) were moved to `modelcontextprotocol/servers-archived`.
