Mem0 Plugin for Claude Code, Claude Cowork & Cursor

Add persistent memory to your AI workflows. Store, retrieve, and manage memories across sessions using the Mem0 Platform. Works with Claude Code (CLI), Claude Cowork (desktop app), and Cursor.

Step 1: Set your API key

You must complete this step before installing the plugin.

Sign up at app.mem0.ai if you haven't already
Go to app.mem0.ai/dashboard/api-keys
Click Create API Key and copy the key (starts with m0-)

Add it to your shell profile:

# For zsh (default on macOS)
echo 'export MEM0_API_KEY="m0-your-api-key"' >> ~/.zshrc
source ~/.zshrc

# For bash
echo 'export MEM0_API_KEY="m0-your-api-key"' >> ~/.bashrc
source ~/.bashrc

Confirm it's set:

echo $MEM0_API_KEY
# Should print: m0-your-api-key

Step 2: Install the plugin

Choose one of the options below. All require MEM0_API_KEY to be set first (see above).

Claude Code (CLI) / Claude Cowork (Desktop)

Claude Code and Claude Cowork share the same plugin system.

CLI:

/plugin marketplace add mem0ai/mem0
/plugin install mem0@mem0-plugins

Cowork desktop app: Open the Cowork tab, click Customize in the sidebar, click Browse plugins, and install Mem0.

This installs the full plugin including the MCP server, lifecycle hooks (automatic memory capture), and the Mem0 SDK skill.

Cursor

Already have mem0 configured as an MCP server? Remove the existing entry from your Cursor MCP settings before installing to avoid duplicate tools.

Option A — One-click deeplink (installs MCP server only):

Install Mem0 MCP in Cursor

Option B — Manual configuration (MCP server only):

Add the following to your .cursor/mcp.json:

{
  "mcpServers": {
    "mem0": {
      "url": "https://mcp.mem0.ai/mcp/",
      "headers": {
        "Authorization": "Token ${env:MEM0_API_KEY}"
      }
    }
  }
}

Option C — Cursor Marketplace (full plugin with hooks and skills):

Install from the Cursor Marketplace for the complete experience including lifecycle hooks and the Mem0 SDK skill.

Verify it works

After installing, confirm the MCP server is connected:

Start a new session (or restart your current one)
Ask: "List my mem0 entities" or "Search my memories for hello"
If the mem0 tools appear and respond, you're all set
