MCP 服务器

NEXUS Memory MCP App

A sovereign, six-layer permanent memory system that provides users with a structured and persistent personal knowledge base across VS Code, Claude, and ChatGPT. It utilizes a neural mesh architecture and ENGRAM O(1) lookup to ensure data ownership and constant-time memory retrieval.

🧠 NEXUS Memory MCP App

The first sovereign memory dashboard for VS Code, Claude & ChatGPT.

Why NEXUS Memory?

Feature	Copilot Memory	NEXUS Memory
Retention	28 days	Permanent
Scope	Repository only	Your entire life
Structure	Flat	6 semantic layers
Ownership	GitHub servers	You own it (BYOS)
Certification	None	Bitcoin OTS
Lookup speed	O(n) vector	O(1) ENGRAM

Features

6-Layer Memory Architecture (L1-L6)
- L1: Working memory (24h TTL)
- L2: Episodic (events, experiences)
- L3: Semantic (facts, knowledge)
- L4: Intent (goals, objectives)
- L5: Provenance (sources)
- L6: Policy (rules, constraints)
Neural Mesh - 8 specialized ganglions with consensus voting
ENGRAM O(1) - Constant-time memory lookup via multi-head SHA-256
Tension Detection - Auto-detect contradictions and outdated info
Cross-Platform - Works in VS Code, Claude Desktop, and ChatGPT
