Installation

Ajoutez ceci à la configuration MCP de votre client (Claude Desktop : claude_desktop_config.json ; Cursor : .cursor/mcp.json ; VS Code et les autres utilisent la même forme « mcpServers »).

NPM package @memory-nexus/mcp
Claude Code 
claude mcp add memory-nexus-mcp -e 'NEXUS_API_KEY=<NEXUS_API_KEY>' -- npx -y @memory-nexus/mcp@1.0.0

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.

npx -y @memory-nexus/mcp
Claude Code / Cursor / Windsurf

Add to your .mcp.json:

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

Tools

Core Memory
ToolDescription
rememberStore a memory with context, importance, and metadata
recallSemantic search across all memories (by meaning, not keywords)
connectCreate relationships between memories (build knowledge graphs)
forgetRemove a memory
statsMemory statistics
contextSession context summary (preferences, decisions, patterns)
Agent Self-Continuity
ToolDescription
awakenRestore identity from previous sessions (call at session start)
hibernateSave session state for next awakening (call at session end)
Intelligence Packs
ToolDescription
list_hatsBrowse available Intelligence Packs
wear_hatActivate a pack (imports expert knowledge into your memory)

How It Works

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)

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..." })

Architecture

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

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.
