What is Memsolus?

Memsolus is a persistent memory platform for AI agents. It lets your AI assistant remember context across conversations, track decisions, search past knowledge, and navigate entity relationships through a knowledge graph.

This package exposes the full Memsolus API as an MCP (Model Context Protocol) server, so any MCP-compatible AI client — Claude Desktop, Claude Code, Cursor, Windsurf, VS Code Copilot, Zed, and others — can store and retrieve memories, query knowledge, and traverse entity graphs without custom integration code.

---

Prerequisites

• A Memsolus account (sign up)
• An API key (see Getting an API Key below)
• Node.js 18+ or Bun

---

Getting an API Key

1. Sign up or log in at app.memsolus.com
2. Go to Settings > API Keys
3. Click Create API Key
4. Give it a name (e.g., Claude Desktop)
5. Select permissions: at minimum MemoryRead and MemoryWrite. For full access, also enable KnowledgeRead and DashboardRead
6. Copy the key — it starts with msk_ and you will not be able to see it again after closing the dialog
7. Set the key as the MEMSOLUS_API_KEY environment variable or paste it directly into your client config

---

Installation

Choose the section that matches your AI client. All configurations use npx -y @memsolus/mcp, which runs the latest published version without a local install step.

Claude Code

Run this command in your terminal:

claude mcp add memsolus -- npx -y @memsolus/mcp

To pass the API key inline without setting an environment variable:

claude mcp add memsolus -e MEMSOLUS_API_KEY=msk_your_key_here -- npx -y @memsolus/mcp

After adding, restart Claude Code or run /mcp to confirm that memsolus appears in the server list.

Claude Desktop

Locate and open your Claude Desktop configuration file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json

Add the following entry inside mcpServers:

{
  "mcpServers": {
    "memsolus": {
      "command": "npx",
      "args": ["-y", "@memsolus/mcp"],
      "env": {
        "MEMSOLUS_API_KEY": "msk_your_key_here"
      }
    }
  }
}
