## 🎯 Overview
This MCP server implements the context engineering methodology created by **[Cole Medin](https://github.com/coleam00)** in his [Context Engineering Introduction repository](https://github.com/coleam00/context-engineering-intro). It provides intelligent automation for creating comprehensive Product Requirements Prompts that account for your existing codebase context.
### What This Server Does
The Context Engineering MCP Server intelligently analyzes your existing codebase and automatically generates:
- 🔍 **Contextual Questions** based on detected patterns and frameworks
- 📋 **Comprehensive INITIAL.md** documentation following Cole's methodology
- 📝 **Product Requirements Prompts** (PRPs) using proven templates
- 🎯 **Execution Guidance** with agent recommendations and task breakdowns
- 💾 **Persistent Storage** for managing PRPs and project context
- 🔗 **Archon Integration** for seamless task and knowledge management
### Why Use This Server?
Instead of starting with blank requirements documents:
1. **Analyzes your existing code** to understand architecture and patterns
2. **Asks intelligent questions** specific to your tech stack and domain
3. **Synthesizes insights** into comprehensive documentation
4. **Generates actionable PRPs** that account for your current context
5. **Provides storage and versioning** for long-term project management
## 📋 MCP Tools (9 Available)

1. **`list_templates`** - List all available PRP templates with optional category filtering
2. **`generate_prp`** - Generate a Product Requirements Prompt based on a template and project context
3. **`validate_prp`** - Validate a PRP against context engineering best practices
4. **`search_templates`** - Search for templates by name, description, or tags
5. **`create_custom_template`** - Create new custom PRP templates
6. **`analyze_context`** - Analyze project context to recommend suitable templates and improvements
### Storage & Management Tools
7. **`list_prps`** - List all stored PRPs with filtering and search capabilities

## 📖 Usage Examples
### Basic PRP Generation
```javascript
// List available templates
const templates = await mcp.call('list_templates', { category: 'web-app' });
// Generate a PRP for a Next.js project
const prp = await mcp.call('generate_prp', {
templateId: 'nextjs-app-template',
projectContext: {
name: 'E-commerce Platform',
domain: 'retail',
stakeholders: ['Product Manager', 'Engineering Team', 'Design Team'],
objectives: ['Build scalable e-commerce platform', 'Implement modern UX'],
constraints: ['Budget: $50k', 'Timeline: 3 months']
},
saveToStorage: true,
outputFormat: 'markdown'
});
```
### Context Analysis Workflow
```javascript
// Analyze project context
const analysis = await mcp.call('analyze_context', {
projectContext: {
name: 'Mobile Banking App',
domain: 'fintech',
description: 'Secure mobile banking application with real-time transactions',
stakeholders: ['Bank Executives', 'Compliance Team', 'Customers'],
constraints: ['PCI DSS Compliance', 'SOX Compliance', 'High Security Requirements']
}
});
// Use recommended template
const prp = await mcp.call('generate_prp', {
templateId: analysis.recommendedTemplates[0].id,
projectContext: analysis.enhancedContext
});
```
### Storage Management
```javascript
// List stored PRPs
const prps = await mcp.call('list_prps', {
category: 'fintech',
status: 'active',
limit: 10
});
// Update a PRP
const updated = await mcp.call('update_prp', {
id: 'prp-123',
updates: {
status: 'completed',
metadata: { version: '2.0' }
},
comment: 'Updated requirements based on stakeholder feedback'
});
```

```bash
# Run all tests
npm test
# Run tests with coverage
npm run test:coverage
# Run specific test suites
npm run test:unit # Unit tests
