Multi-Platform MCP Integration

Complete guide to the unified learning system that works across Cursor, Claude Code, and all AI platforms

🌐 Multi-Platform MCP Integration

One learning system. All platforms. Zero duplication.

The MCP Development AI system now supports platform-agnostic learning, enabling Cursor, Claude Code, Claude Desktop, and any future AI tools to share the same intelligent agent system.

🎯 Overview

The Problem We Solved

Before Session 16, the MCP system was tightly coupled to Cursor:

Agent IDs like cursor-angular-agent
Platform-specific detection
Decisions isolated to one tool
No cross-platform learning

The Solution

Platform-Agnostic Architecture where:

✅ Agents are functional (angular-agent, not cursor-angular-agent)
✅ Platform tracked for analytics, not routing
✅ All platforms share decisions in one unified pool
✅ Cross-platform learning - Cursor decisions improve Claude Code and vice versa
✅ Backwards compatible - Legacy agent IDs still work

Key Principles

Principle	Implementation	Benefit
Platform-Agnostic Agents	Functional IDs (e.g., `angular-agent`)	All platforms use same agents
Platform Metadata	Tracked in `session.platform`	Analytics without routing impact
Shared Decision Pool	One database for all platforms	Cross-platform learning
Automatic Detection	Multi-layered platform detection	No manual configuration
Legacy Support	`normalizeAgentId()` function	Backwards compatible

🔧 Technical Implementation

Platform Detection

The system automatically detects which AI platform is making requests:

// Multi-layered detection strategy
export function detectPlatform(): PlatformMetadata {
  // 1. Environment variables
  if (process.env.CLAUDE_CODE_AGENT === 'true') {
    return { type: 'claude-code', environment: detectEnvironment() };
  }

  // 2. Process arguments
  const args = process.argv.join(' ');
  if (args.includes('claude-code')) {
    return { type: 'claude-code' };
  }

  // 3. Parent process inspection
  const execPath = process.env._ || '';
  if (execPath.includes('claude') && !execPath.includes('cursor')) {
    return { type: 'claude-code' };
  }

  // 4. Cursor detection
  if (isCursor()) {
    return { type: 'cursor', environment: 'cursor' };
  }

  // 5. Fallback
  return { type: 'external' };
}

Platform Metadata Structure

interface PlatformMetadata {
  type: 'cursor' | 'claude-code' | 'claude-desktop' | 'api' | 'external';
  version?: string;      // e.g., "claude-code-2.0.75"
  model?: string;        // e.g., "claude-opus-4-5-20251101"
  environment?: string;  // e.g., "vscode", "terminal"
  clientId?: string;     // Unique client identifier
}

Decision Structure with Platform

interface DevelopmentDecision {
  id: string;
  agentId: string;  // NOW: "architecture-agent" (not "cursor-architecture-agent")

  session: {
    type: PlatformType;
    sessionNumber: number;
    sessionID: string;
    platform: PlatformMetadata;  // ✨ NEW: Platform tracking
  };

  type: DecisionType;
  question: string;
  chosen: string;
  reasoning: string;
  confidence: number;
  // ... rest of decision fields
}

🌟 New Features

1. Platform-Agnostic Agent IDs

Before (Session <16):

// Platform-specific IDs
agentId: "cursor-angular-agent"
agentId: "cursor-architecture-agent"

After (Session 16+):

// Functional IDs - work across all platforms
agentId: "angular-agent"
agentId: "architecture-agent"

Migration:

✅ Automatic via normalizeAgentId()
✅ Legacy IDs still work
✅ No breaking changes

normalizeAgentId('cursor-angular-agent')  // → 'angular-agent'
normalizeAgentId('angular-agent')         // → 'angular-agent'

2. get_platform_info Tool

New MCP tool for platform debugging and analytics:

// Usage
const info = await get_platform_info({ includeHistory: true });

// Returns
{
  success: true,
  platform: {
    type: "claude-code",
    version: "2.0.75",
    model: "claude-opus-4-5-20251101",
    environment: "vscode",
    clientId: "cc-session-123"
  },
  session: {
    type: "claude-code",
    sessionNumber: 16,
    sessionID: "16.8"
  },
  capabilities: {
    sharedLearning: true,
    crossPlatformDecisions: true,
    legacyAgentIdSupport: true,
    platformAgnosticRouting: true
  },
  supportedPlatforms: [
    "cursor",
    "claude-code",
    "claude-desktop",
    "api",
    "external"
  ],
  usageHistory: {  // Only with includeHistory: true
    "cursor": 150,
    "claude-code": 45
  }
}

3. Enhanced get_stats Tool

Now includes platform breakdown:

const stats = await get_stats();

// Returns (new fields)
{
  stats: {
    version: "4.0.0",
    currentPlatform: "claude-code",  // ✨ NEW
    currentSession: 16,

    platforms: {  // ✨ NEW
      "cursor": {
        decisionCount: 150,
        successRate: 87,
        lastActive: "2025-12-28T20:48:03Z"
      },
      "claude-code": {
        decisionCount: 45,
        successRate: 92,
        lastActive: "2025-12-28T20:48:38Z"
      }
    },

    // ... rest of stats
  }
}

🔄 Cross-Platform Learning

How It Works

Cursor makes decision → Logged with platform="cursor"
                          ↓
                    Stored in unified database
                          ↓
                    Agent learns pattern
                          ↓
Claude Code requests context → Gets pattern from Cursor
                          ↓
              Claude Code benefits from Cursor's learning
                          ↓
Claude Code makes improved decision → Logged with platform="claude-code"
                          ↓
                    Agent gets smarter
                          ↓
              Both platforms benefit from combined intelligence

Example Scenario

Day 1 - Cursor Session

// Developer using Cursor makes architectural decision
log_decision({
  type: 'architecture',
  question: 'How to structure user authentication?',
  chosen: 'JWT with refresh tokens in httpOnly cookies',
  reasoning: 'More secure than localStorage, prevents XSS attacks',
  confidence: 0.95
});
// Platform: cursor, AgentID: architecture-agent

Day 2 - Claude Code Session

// Developer using Claude Code needs auth guidance
const context = await preflight({ task: 'Implement auth system' });

// Claude Code receives:
{
  historicalHints: [
    "JWT with refresh tokens in httpOnly cookies - prevents XSS (95% confidence)"
  ],
  // This came from Cursor's decision!
}

Result
- Claude Code benefits from Cursor's learning
- No manual knowledge transfer needed
- Consistent best practices across platforms

📊 Analytics & Monitoring

Platform Statistics

Track which platforms contribute most to the learning system:

// Per-agent platform breakdown
const angularStats = getAgentPlatformStats('angular', decisions);

// Returns
{
  "cursor": {
    count: 89,
    successRate: 0.87
  },
  "claude-code": {
    count: 34,
    successRate: 0.92
  }
}

Cross-Platform Success Rates

Compare agent performance across platforms:

// Get all stats
const stats = await get_stats();

// Analyze platform differences
const cursorAngularSuccess = stats.platforms.cursor.successRate;
const claudeAngularSuccess = stats.platforms['claude-code'].successRate;

if (claudeAngularSuccess > cursorAngularSuccess) {
  console.log('Claude Code users are making better Angular decisions!');
}

🎓 Best Practices

For Developers

// ✅ DO: Let platform auto-detect
// The system knows which tool you're using

// ✅ DO: Use the same session across platforms
// Session 16 works in both Cursor and Claude Code

// ✅ DO: Report outcomes regardless of platform
// All platforms benefit from feedback
await report_outcome({
  decisionId: 'dec_123',
  wasSuccessful: true
});

// ❌ DON'T: Specify platform manually
// Let the detection handle it automatically

For Platform Integration

// ✅ DO: Set appropriate environment variables
process.env.CLAUDE_CODE_AGENT = 'true';
process.env.CLAUDE_MODEL = 'claude-opus-4-5-20251101';

// ✅ DO: Pass through environment in MCP config
{
  "env": {
    "CLAUDE_CODE_AGENT": "true",
    "CLAUDE_SESSION_ID": "${sessionId}"
  }
}

// ✅ DO: Use platform info for debugging
if (process.env.DEBUG_PLATFORM) {
  const info = await get_platform_info({ includeHistory: true });
  console.log('Platform:', info.platform);
}

📝 Migration Guide

Upgrading from Pre-Session 16

No action required! The system is backwards compatible:

// Old decisions with cursor-* IDs
{ agentId: "cursor-angular-agent", ... }

// Automatically normalized to
{ agentId: "angular-agent", ... }

// When queried, both formats work:
getAgentDecisions('angular')  // Returns decisions from both formats

Adding New Platforms

To add support for a new platform:

Add platform type:

// In types/index.ts
export type PlatformType =
  | 'cursor'
  | 'claude-code'
  | 'your-new-platform'  // ← Add here
  | ...

Add detection logic:

// In session-detector.ts
function isYourPlatform(): boolean {
  return process.env.YOUR_PLATFORM_AGENT === 'true';
}

Update detection function:

export function detectPlatform(): PlatformMetadata {
  if (isYourPlatform()) {
    return { type: 'your-new-platform', ... };
  }
  // ... existing detection
}

Create MCP config:

{
  "mcpServers": {
    "gograb-development-ai": {
      "env": {
        "YOUR_PLATFORM_AGENT": "true"
      }
    }
  }
}

That's it! All agents and learning automatically work.
