Spec-Driven Development MCP Server

What is Spec-Driven Development MCP Server?

A Model Context Protocol (MCP) server that provides structured prompts for generating requirements, design documents, and code in a systematic spec-driven development workflow. It is intended for developers who want to move from ad‑hoc “vibe coding” to a traceable, specification‑first approach.

How to use Spec-Driven Development MCP Server?

Requires Node.js 20+. Install by adding the server configuration in mcp.json (command: npx, args: ["-y","mcp-server-spec-driven-development@latest"]) or by clicking the VS Code install buttons in the README. Invoke the three available prompts in order: generate-requirements, generate-design-from-requirements, generate-code-from-design.

Key features of Spec-Driven Development MCP Server

• Structured workflow: requirements → design → code
• Uses EARS (Easy Approach to Requirements Syntax) format
• Integrates with any MCP‑compatible tool (VS Code, etc.)
• Generates markdown files in a specs/ folder

Use cases of Spec-Driven Development MCP Server

• Creating a formal requirements document from high‑level user stories
• Deriving a design document directly from previously written requirements
• Generating implementation code that is traceable back to a design
• Enforcing a consistent spec‑driven process in team projects

FAQ from Spec-Driven Development MCP Server

What problem does this server solve?

It replaces unstructured “vibe coding” with a reproducible, spec‑driven workflow where requirements, design, and code are linked, improving clarity and maintainability.

What are the runtime requirements?

Node.js version 20 or later. No other external services or databases are mentioned.

Where are the generated files saved?

generate-requirements writes to specs/requirements.md; generate-design-from-requirements writes to specs/design.md; generate-code-from-design writes implementation files into the project root folder.

Does this server require any paid subscriptions or API keys?

No. The README lists no API keys, authentication, or paid tiers. It runs entirely via npx.

How is this different from a regular code‑generation tool?

It enforces a three‑step process (requirements → design → code) using the EARS format, ensuring every line of code is traceable back to a written requirement.
