# IT-MCP Integration Readiness Summary
**Date**: 2025-11-01
**Status**: Phase 1 Foundation Complete ✅
---
## Completed Infrastructure (Phase 1)
### 1. DatabaseSyncService (`src/services/databaseSync.ts`)
✅ **Created**: 231 lines
**Purpose**: Hybrid SQLite/PostgreSQL synchronization
**Features**:
- Background sync worker (configurable interval)
- Conflict resolution strategies (last-write-wins, manual, merge)
- Health monitoring and status reporting
- Offline resilience with local queue
- Batch upload optimization
**Configuration**:
```typescript
new DatabaseSyncService(planner, {
postgresConnectionString: process.env.POSTGRES_URL,
syncIntervalMs: 60000,
batchSize: 50,
conflictResolution: "last-write-wins",
enableAutoSync: true
});
```
**Status**: ✅ Ready to connect when PostgreSQL available
---
### 2. CommandQueueService (`src/services/commandQueue.ts`)
✅ **Created**: 375 lines
**Purpose**: Local command queue with retry logic
**Features**:
- SQLite persistence (`mcp_command_queue.db`)
- Priority-based ordering (urgent > high > normal > low)
- Automatic retry with max retry limits
- Status tracking (queued → picked → executing → completed/failed)
- Queue statistics and health monitoring
- Old command purging (configurable retention)
**Schema**:
```sql
CREATE TABLE command_queue (
job_id TEXT PRIMARY KEY,
tool_name TEXT NOT NULL,
params TEXT NOT NULL,
requested_capabilities TEXT NOT NULL,
target_agent_id TEXT,
status TEXT CHECK(status IN ('queued', 'picked', 'executing', 'completed', 'failed', 'timeout')),
priority TEXT CHECK(priority IN ('low', 'normal', 'high', 'urgent')),
created_at TEXT NOT NULL,
retry_count INTEGER DEFAULT 0,
max_retries INTEGER DEFAULT 3
);
```
**Status**: ✅ Fully operational locally, ready for remote sync
---
### 3. AutoDiscoveryService (`src/services/autoDiscovery.ts`)
✅ **Created**: 178 lines
**Purpose**: MCP server registration and heartbeat
**Features**:
- Server capability advertisement
- Auto-registration with central registry
- Heartbeat mechanism (default 30s interval)
- Dynamic capability updates
- Graceful deregistration on shutdown
**Advertised Data**:
```typescript
{
serverId: UUID,
serverType: "mcp-server",
hostname: string,
capabilities: ['local-shell', 'local-sudo', 'ssh-linux', ...],
tools: ['system-overview', 'mac-diagnostics', ...],
version: "0.1.0",
metadata: { platform, nodeVersion, startedAt }
}
```
**Status**: ⏳ Awaiting OpenAPI specs for `/api/v1/servers/register` endpoint
---
### 4. KeycloakAuthService (`src/services/keycloakAuth.ts`)
✅ **Created**: 280 lines
**Purpose**: JWT token lifecycle management
**Features**:
- Client credentials flow (service-to-service)
- Password flow (user-based, optional)
- Auto-refresh before expiry (90% of lifetime)
- Token validation and decoding
- Graceful token revocation
**Authentication Flows**:
```typescript
// Client credentials (recommended for IT-MCP)
const authService = new KeycloakAuthService({
serverUrl: "https://acdev.host:8080",
realm: "mcp-agents",
clientId: "it-mcp-server",
clientSecret: process.env.KEYCLOAK_CLIENT_SECRET
});
const tokenSet = await authService.authenticate();
const token = await authService.getAccessToken(); // Auto-refreshes
```
**Status**: ⏳ Awaiting Keycloak realm configuration and client credentials
---
### 5. CLAUDE.md Updated
✅ **Updated**: Now 790 lines (was 543)
**Purpose**: Comprehensive hybrid architecture documentation
**New Sections Added**:
- Hybrid Architecture overview (local vs distributed mode)
- Database Layer (SQLite + PostgreSQL schemas)
- Integration Services (DatabaseSync, CommandQueue, AutoDiscovery, KeycloakAuth)
- Environment variables for distributed mode
- Integration status tracking
- Next steps for server team
**Status**: ✅ Complete and accurate
---
## Integration Dependencies
### Awaiting from Server Team
#### 1. OpenAPI Specification
**Needed Endpoints**:
- `POST /api/v1/servers/register` - Server registration
- `POST /api/v1/servers/{id}/heartbeat` - Heartbeat submission
- `GET /api/v1/commands/poll` - Poll for available commands
- `POST /api/v1/commands/{job_id}/result` - Submit command result
- `DELETE /api/v1/servers/{id}` - Deregister server
**Format**: OpenAPI 3.0 JSON/YAML for client generation
#### 2. PostgreSQL Access
**Needed**:
- Connection string (host, port, database, user, password)
- Schema setup scripts (create tables, indexes)
- Migration guide from SQLite schema to PostgreSQL
**Schema Tables Required**:
- `thought_sessions`
- `structured_thoughts`
- `mcp_agents`
- `command_queue`
- `command_audit`
- `agent_heartbeats`
- `tool_runs`
#### 3. Keycloak Configuration
**Needed**:
- Realm name (e.g., `mcp-agents`)
- Client ID for IT-MCP
- Client secret (for client credentials flow)
- Role → Capability mappings
- Token lifetime configuration
#### 4. Redis Specifications
**Needed**:
- Redis connection string
- Pub/sub channel names for:
- Agent heartbeats
- Command dispatch
- Command results
- Message format specifications
