# MCP Resources Implementation Plan
**Project**: MCP ADR Analysis Server
**Plan Date**: 2025-10-07
**Target Completion**: 8 weeks (4 phases × 2 weeks)
**Priority**: High (Critical architecture improvement)
---
## Overview
This plan addresses the resource gap identified in the MCP Resources Audit. The project currently has only 3 resources despite 40+ tools, with a significant portion of tools performing read-only operations that should be exposed as resources.
### Objectives
1. **Refactor existing resources** to return data instead of prompts
2. **Implement 20+ new resources** for read-only data access
3. **Add templated resource support** for individual entity access
4. **Establish caching infrastructure** for resource optimization
5. **Reduce tool count** by migrating read-only tools to resources
### Success Criteria
- ✅ Minimum 20 resources exposed (from current 3)
- ✅ All read-only tools either migrated or deprecated
- ✅ 60%+ cache hit rate for frequently accessed resources
- ✅ 50% faster response times for data access
- ✅ Zero breaking changes for existing tool consumers
---
## Phase 1: Foundation & Critical Resources
**Duration**: Week 1-2
**Priority**: Critical
**Dependencies**: None
### Objectives
- Fix existing resource implementations
- Establish resource infrastructure
- Implement most critical resources
### Tasks
#### 1.1 Resource Infrastructure Setup
**File**: `src/resources/resource-cache.ts` (NEW)
```typescript
/**
* Resource-level caching infrastructure
*/
export class ResourceCache {
private cache = new Map<string, CacheEntry>();
async get<T>(key: string): Promise<T | null> {
const entry = this.cache.get(key);
if (entry && entry.expiry > Date.now()) {
return entry.data as T;
}
this.cache.delete(key);
return null;
}
set(key: string, data: any, ttl: number): void {
this.cache.set(key, {
data,
expiry: Date.now() + ttl * 1000,
createdAt: Date.now()
});
}
clear(pattern?: string): void {
if (!pattern) {
this.cache.clear();
return;
}
for (const key of this.cache.keys()) {
if (key.includes(pattern)) {
this.cache.delete(key);
}
}
}
getStats(): CacheStats {
const entries = Array.from(this.cache.values());
return {
totalEntries: this.cache.size,
validEntries: entries.filter(e => e.expiry > Date.now()).length,
expiredEntries: entries.filter(e => e.expiry <= Date.now()).length,
cacheSize: JSON.stringify(entries).length
};
}
}
interface CacheEntry {
data: any;
expiry: number;
createdAt: number;
}
interface CacheStats {
totalEntries: number;
validEntries: number;
expiredEntries: number;
cacheSize: number;
}
// Singleton instance
export const resourceCache = new ResourceCache();
```
**Estimated Effort**: 4 hours
**Tests Required**: Unit tests for cache operations
---
#### 1.2 Refactor Existing Resources
**Files to Modify**:
- `src/resources/index.ts` (ALL functions)
**Changes**:
1. **generateArchitecturalKnowledgeGraph**
- Remove prompt-based response
- Load actual knowledge graph data
- Return structured JSON data
- Implement caching
2. **generateAnalysisReport**
- Remove prompt-based response
- Generate actual analysis data
- Return report structure
- Implement caching
3. **generateAdrList**
- Already returns actual data (✓)
- Add caching support
- Enhance with metadata
**Example Refactor**:
```typescript
// BEFORE (Prompt-based)
export async function generateArchitecturalKnowledgeGraph(
projectPath: string
): Promise<ResourceGenerationResult> {
return {
data: {
prompt: knowledgeGraphPrompt,
instructions: "Submit to AI..."
},
contentType: 'application/json',
ttl: 3600
};
}
// AFTER (Data-based)
export async function generateArchitecturalKnowledgeGraph(
projectPath: string
): Promise<ResourceGenerationResult> {
const cacheKey = `knowledge-graph:${projectPath}`;
// Check cache
const cached = await resourceCache.get(cacheKey);
if (cached) {
return cached;
}
// Load actual knowledge graph
const kgManager = new KnowledgeGraphManager();
const snapshot = await kgManager.loadKnowledgeGraph();
const technologies = await detectTechnologies(projectPath);
const patterns = await detectPatterns(projectPath);
const adrs = await discoverAdrs(projectPath);
const result = {
data: {
projectId: Buffer.from(projectPath).toString('base64'),
timestamp: new Date().toISOString(),
version: '1.0.0',
metadata: {
