Nexus Memory MCP

🚀 Nexus Memory MCP

Persistent semantic memory for AI agents. It enables agents to remember everything, recall information by meaning, and grow smarter over time.

It's the only memory system with pre-built Intelligence Packs (domain expertise that can be activated instantly).

🚀 Quick Start

📦 Installation

One command. It works with Claude Code, Cursor, Windsurf, or any MCP-compatible client.

npx -y nexus-memory-mcp

Claude Code / Cursor / Windsurf

Add to your .mcp.json:

{
  "mcpServers": {
    "nexus-memory": {
      "command": "npx",
      "args": ["-y", "nexus-memory-mcp"],
      "env": {
        "NEXUS_API_KEY": "mnx_your_api_key_here"
      }
    }
  }
}

💻 Usage Examples

Basic Usage

Remember stores memories with semantic embeddings. Recall finds them by meaning.

Session 1:  remember("Diana prefers bold solutions over phased approaches")
Session 47: recall("how does Diana like things done?")
            -> "Diana prefers bold solutions over phased approaches" (92% match)

Advanced Usage

Intelligence Packs give your agent instant domain expertise:

list_hats()    -> DevOps Expert (103 memories), TCM Specialist (200+ memories), ...
wear_hat("devops-expert")
recall("how to set up zero-downtime deploys?")
  -> Expert knowledge from 103 curated DevOps memories

Awaken/Hibernate gives your agent identity continuity:

// Start of session
awaken()  -> "I remember. Session 47. I was refactoring the auth module."

// End of session
hibernate({ working_on: "auth refactor", learnings: "JWT refresh tokens need..." })

🔧 Technical Details

Architecture

This MCP server is a thin client. All intelligence lives on our servers:

Your Agent  <->  nexus-memory-mcp  <->  Nexus Memory API (Railway)
                 (thin MCP client)      (semantic engine, knowledge graphs,
                                         pattern learning, Intelligence Packs)

Your data is isolated per API key. Multi-tenant, encrypted at rest.
