MCP: Model Context Protocol Server Development

Build, review, and debug MCP servers that expose tools, resources, and prompts to AI coding assistants. The goal is secure, well-structured servers that follow the protocol spec and don't become yet another server with preventable injection vulnerabilities.

Target versions (September 2026):

• MCP specification: 2026-07-28 (current stable; stateless core, extensions framework, and no initialize/session handshake)
• TypeScript SDK: @modelcontextprotocol/server, @modelcontextprotocol/client, and @modelcontextprotocol/core 2.0.0 (the monolithic @modelcontextprotocol/sdk 1.30.0 is the legacy line)
• Python SDK: mcp 2.1.1 (2.x stable; review the v1-to-v2 migration guide)
• Protocol transports: stdio and Streamable HTTP. The standalone HTTP+SSE transport is deprecated and available only as a temporary legacy bridge
