Cortex Memory MCP Server

🔒 CRITICAL: CORTEX MCP CONFIGURATION RESTRICTION

⚠️ STRICTLY PROHIBITED: Multiple Cortex MCP configurations ✅ MANDATORY: Only ONE Cortex configuration allowed

RULE: Use only [mcp_servers.cortex] - no alternatives, backups, or multiples for Cortex only

Check: Run npm run mcp:check-config to verify compliance

See: MCP-CONFIGURATION-RULES.md for detailed restrictions


Overview

Cortex Memory MCP Server v2.0.0 is an AI-optimized knowledge management system that provides semantic search, memory storage, and intelligent deduplication through the Model Context Protocol (MCP). The system uses Qdrant vector database for knowledge operations with a streamlined 3-tool interface designed specifically for AI agent integration.

★ Insight ───────────────────────────────────── Current Status (2025-11-04): Development phase with solid core infrastructure. TypeScript compilation, linting, and build processes are working correctly. Test suite has some timeout issues on Windows but basic functionality is verified. Core MCP integration is functional. ─────────────────────────────────────────────────

Architecture

Qdrant-First Database Layer

The system uses Qdrant as the primary and only database backend:

Qdrant Responsibilities:

  • Vector similarity search and semantic understanding
  • Embedding storage and retrieval with OpenAI embeddings
  • Approximate nearest neighbor search
  • Collection management and sharding
  • Semantic ranking and relevance scoring
  • All data storage and retrieval operations

Key Architecture Benefits:

  • Single database backend for simplicity and reliability
  • Optimized for vector operations and semantic search
  • Automatic schema management
  • Type-safe TypeScript operations
  • Comprehensive error handling with graceful degradation

Service Layer

🚨 ARCHITECTURAL ISSUE: Service Layer Exists But Not Fully Wired

Implemented Services (Not Connected to Main Server):

  • Memory Store Service - Comprehensive validation, deduplication, and storage orchestration
  • Memory Find Service - Multi-strategy search: semantic, keyword, and hybrid modes
  • Similarity Service - Content similarity detection (85% threshold) with Jaccard algorithms
  • Deduplication Service - Advanced duplicate detection with content hashing and similarity scoring
  • Validation Service - Complete validation for all 16 knowledge types with business rules
  • Auto-Purge Service - TTL-based cleanup (90-day for most types, 30-day for PR context)
  • Expiry Worker Service - Scheduled cleanup of expired items (P6-T6.2)
  • Chunking Service - Content chunking capability (implemented but not yet wired to main flow)

Current Problem: Main server bypasses the comprehensive service layer and directly accesses the database layer. This means:

  • Advanced features not accessible to end users
  • Business rules not enforced in main workflow
  • Multi-strategy search not available (only semantic search works)
  • Content chunking not active (8000 char limit enforced)
  • Similarity analysis not exposed (basic deduplication only)

What Users Get vs What Exists:

  • Basic MCP tools only → ✅ Comprehensive orchestration layer exists
  • Semantic search only → ✅ Multi-strategy search service exists
  • 8000 char limit → ✅ Chunking service exists for large content
  • Basic validation → ✅ Full business rules validation exists

Next Steps:

  1. Connect main server to MemoryStoreOrchestrator - Enable full service layer
  2. Integrate Chunking Service - Remove 8000 char limit, enable parent-child
  3. Wire Memory Find Service - Enable multi-strategy search
  4. Expose Advanced Features - Business rules, similarity analysis, etc.

Integration Layer

  • MCP Protocol - Model Context Protocol for seamless Claude Code integration
  • REST API - HTTP endpoints for external system integration
  • Unified Interface - Single entry point for all database operations

Knowledge Types

The system supports 16 comprehensive knowledge types:

  1. entity - Graph nodes representing any concept or object
  2. relation - Graph edges connecting entities with typed relationships
  3. observation - Fine-grained data attached to entities
  4. section - Document containers for organizing knowledge
  5. runbook - Step-by-step operational procedures
  6. change - Code change tracking and history
  7. issue - Bug tracking and problem management
  8. decision - Architecture Decision Records (ADRs)
  9. todo - Task and action item tracking
  10. release_note - Release documentation and changelogs
  11. ddl - Database schema migration history
  12. pr_context - Pull request metadata and context
  13. incident - Incident response and management
  14. release - Release deployment tracking 15.risk - Risk assessment and mitigation
  15. assumption - Business and technical assumptions

Basic system monitoring for Cortex memory.

Operations:

  • health - Database health status
  • stats - Basic database statistics
  • telemetry - Performance report
  • metrics - System metrics

Returns:

  • capabilities (object): Current system capabilities
  • Operation-specific data based on request

Current Limitations:

  • Document management operations not implemented
  • Limited to basic monitoring and statistics
  • No advanced analytics or troubleshooting

Current Advanced Features

Basic Semantic Deduplication

The system detects basic duplicates using content similarity with an 85% threshold:

const duplicateItem = {
  kind: 'entity',
  data: { title: 'User Authentication' },
};

// System will detect duplicates and skip storage
const result = await memory_store({ items: [duplicateItem] });
// Returns: { stored: [], errors: [], autonomous_context: {...} }

Current Limitations:

  • No conflict resolution or merge suggestions
  • No contradiction detection
  • Basic similarity only (no semantic understanding)

Basic Semantic Search

The system provides vector-based semantic search:

const results = await memory_find({
  query: 'authentication best practices',
});

// Returns semantic similarity matches from Qdrant

Current Limitations:

  • Single search strategy (semantic only)
  • No keyword or hybrid search available
  • No query expansion or suggestions
  • Basic similarity scoring only

⚠️ Not Yet Implemented (Target Features)

The following features are documented in the API but not currently implemented:

Multi-Strategy Search

  • Hybrid search combining semantic + keyword
  • Multiple search modes (fast/deep)
  • Query expansion and suggestions

Autonomous Context Generation

  • AI-generated insights and recommendations
  • Smart context and suggestions
  • Advanced search analytics

Advanced Deduplication

  • Contradiction detection
  • Merge suggestions
  • Conflict resolution

Graph Features

  • Entity relationship mapping
  • Graph traversal
  • Relationship-based search

Content Management

  • Document chunking
  • Parent-child relationships
  • Large document handling
