What's your MCP server stack in late 2026?

Developers are discussing MCP server stacks in late 2026, focusing on stdio versus HTTP transport in production, tool scoping, and rate limit patterns. The conversation highlights the need to distinguish genuinely useful servers from demo-only versions. Simultaneously, maintaining accurate tool descriptions is critical, as outdated information causes agents to fail tasks. A 40-line Node script provides a solution by extracting and structuring tool descriptions, ensuring better communication and scalability for MCP server deployments.
