Model Context Protocol Servers Released v2.0.0
The official Model Context Protocol (MCP) servers repository has been upgraded to version 2.0.0, refactoring both TypeScript and Python packages to support modern specifications while maintaining backward compatibility with legacy clients. This major release aligns official reference servers with the latest MCP specification, ensuring developers can build advanced AI integrations with improved stability, security fixes, and new features. TypeScript servers now require Node.js 24 as a minimum floor and have migrated to TS SDK v2 via codemod, alongside various bug fixes for filesystem and other server packages.
## BACKGROUND
Model Context Protocol (MCP) is an open standard introduced by Anthropic in November 2024 to standardize how AI systems and large language models securely connect to external tools, databases, and data sources. MCP servers act as programs exposing specific capabilities—such as file access or code management—to AI applications through these standardized interfaces.
