Microsoft open-sources MCP for Beginners course with six languages and 50+ translations

The course covers MCP basics, security practices, server and client construction, VS Code integration, stdio transport, HTTP streaming, and 13 labs up to PostgreSQL integration. The current protocol version is 2026-07-28, using date-based versioning; it explains stateless requests and the Extensions framework, notes that Roots, Sampling, and Logging are deprecated, and keeps some hands-on samples on 2025-11-25 pending SDK updates. With 50+ built-in translations, Microsoft recommends git sparse-checkout excluding the translations and translated_images directories to cut download time. For .NET, Java, TypeScript, JavaScript, Rust, and Python developers preparing to adopt MCP, this material strings environment setup through production deployment into one path, avoiding guesswork over protocol details; Module 11's 13 labs are directly useful for teams connecting MCP servers to PostgreSQL. For teams maintaining multilingual docs, translation upkeep is handled by Co-op Translator, but repo size grows notably with each language, and cloning without sparse checkout multiplies fetch costs.
