MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.

Overview

AI-generated overview

A local MCP server that supplies structured prompts guiding an assistant through requirements, design and code generation for spec-driven development.

What you can do
Generate a requirements document in EARS format from a high-level description, written to specs/requirements.md
When to use it
Use it when you want a systematic requirements-to-design-to-code workflow instead of ad-hoc coding, for example starting a new application or feature where traceable specifications matter.
Requirements
Local process run via npx from the npm package mcp-server-spec-driven-development; Node.js 20 or later. No authentication, environment variables or headers are declared.
Before you install
The code generation prompt writes implementation code into the project root folder, and the other prompts write documents under specs/, so files in your workspace are created or changed. Review generated output before relying on it.

Installation

In SourceWeft

  1. Open Spec Driven Development in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

Spec-Driven Development MCP Server

[NPM Downloads] [Install in VS Code]

Model Context Protocol (MCP) server that facilitates spec-driven development workflows by providing structured prompts for generating requirements, design documents, and code following a systematic approach.

[Spec-Driven Development Server MCP server]

🎯 Purpose

This MCP server enables developers to follow a structured spec-driven development approach by providing prompts that guide you through:

  1. Requirements Generation - Create detailed requirements documents using the EARS (Easy Approach to Requirements Syntax) format
  2. Design Generation - Generate design documents based on requirements
  3. Code Generation - Generate implementation code based on design documents

✨ Features

  • Structured Workflow: Follows a clear progression from requirements → design → code
  • EARS Format Support: Uses industry-standard EARS format for requirements documentation
  • MCP Protocol: Integrates seamlessly with MCP-compatible tools and environments

🚀 Quick Start

Prerequisites

  • Node.js 20+

Installation

VS Code

Install the MCP server in VS Code using below buttons:

[Install in VS Code] [Install in VS Code Insiders]

Alternatively, you can add configuration in mcp.json:

json
{    "servers": {        "spec-driven": {            "command": "npx",            "args": [                "-y",                "mcp-server-spec-driven-development@latest"            ]        }    }}
Cursor, Claude Code

Install the MCP server in Cursor using below button:

Alternatively, you can add configuration in mcp.json:

json
{    "mcpServers": {        "spec-driven": {            "command": "npx",            "args": [                "-y",                "mcp-server-spec-driven-development@latest"            ]        }    }}

📋 Available Prompts

1. Generate Requirements Document

  • Name: generate-requirements
  • Description: Generate requirements.md using EARS format
  • Input: High-level requirements of the application. Example: 'A Vue.js todo application with task creation, completion tracking, and local storage persistence'
  • Output: Structured requirements document in specs/requirements.md

2. Generate Design from Requirements

  • Name: generate-design-from-requirements
  • Description: Generate design.md from requirements.md
  • Input: Reads from specs/requirements.md
  • Output: Design document in specs/design.md

3. Generate Code from Design

  • Name: generate-code-from-design
  • Description: Generate code from design.md
  • Input: Reads from specs/design.md
  • Output: Implementation code in the root folder

📖 Workflow Example

  1. Start with Requirements: Use the generate-requirements prompt with your initial requirements text
  2. Create Design: Use generate-design-from-requirements to create a design document based on your requirements
  3. Generate Code: Use generate-code-from-design to generate implementation code from your design

This creates a traceable path from requirements through design to implementation, ensuring consistency and completeness in your development process.

🤔 Why Spec-Driven Development?

Moving beyond Vibe Coding to a structured, specification-driven approach brings clarity, consistency, and maintainability to your development workflow. Instead of coding by intuition alone, Spec-Driven Development provides a systematic foundation that scales with your project's complexity.

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
