About This MCP

Official MCP reference server demonstrating all protocol features (tools, resources, prompts, sampling) for testing and development. One of seven reference servers still maintained after the 2025-05-29 archival of non-core servers; MCP governance moved to the Agentic AI Foundation (Linux Foundation) on 2025-12-09, latest stable spec 2025-11-25 (2026-07-28 revision at release-candidate stage). Not for production use but essential for MCP protocol testing.
