## Description

The SpecCoding MCP Server provides a structured workflow for software development that guides users through five sequential stages: feature definition, requirements gathering, design document creation, task list generation, and task execution. Built in C# with .NET, it manages session state across workflow stages and uses templated prompts to ensure consistent documentation and planning artifacts are created before implementation begins. The server enforces proper workflow progression through stage validation, maintains feature context throughout the process, and generates organized output files including requirements documents in EARS format, comprehensive design documents, and actionable task lists that can be executed by coding agents, making it valuable for teams that want to follow a disciplined approach to feature development with proper documentation and planning.
