Documentation Overview

Memory Nexus MCP

Persistent semantic memory for AI agents. Remember everything, recall by meaning, grow smarter over time.

The only memory system with pre-built Intelligence Packs (domain expertise you can activate instantly).

Install

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

Terminal

npx -y @memory-nexus/mcp

Claude Code / Cursor / Windsurf

Add to your .mcp.json:

config.json

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

Tools

Core Memory

Tool	Description
`remember`	Store a memory with context, importance, and metadata
`recall`	Semantic search across all memories (by meaning, not keywords)
`connect`	Create relationships between memories (build knowledge graphs)
`forget`	Remove a memory
`stats`	Memory statistics
`context`	Session context summary (preferences, decisions, patterns)

Agent Self-Continuity

Tool	Description
`awaken`	Restore identity from previous sessions (call at session start)
`hibernate`	Save session state for next awakening (call at session end)

Intelligence Packs

Tool	Description
`list_hats`	Browse available Intelligence Packs
`wear_hat`	Activate a pack (imports expert knowledge into your memory)

How It Works

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

Code

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)

Intelligence Packs give your agent instant domain expertise:

Code

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:

Code

// 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..." })

Architecture

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

Code

Your Agent  <->  @memory-nexus/mcp  <->  Memory Nexus 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.

Environment Variables

Variable	Required	Description
`NEXUS_API_KEY`	Yes	Your API key (starts with `mnx_`)
`NEXUS_API_URL`	No	Custom API URL (default: production)
