# 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.**

1. Sign up at [app.mem0.ai](https://app.mem0.ai) if you haven't already
2. Go to [app.mem0.ai/dashboard/api-keys](https://app.mem0.ai/dashboard/api-keys)
3. Click **Create API Key** and copy the key (starts with `m0-`)
4. Add it to your shell profile:

   ```bash
   # 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
   ```

5. Confirm it's set:

   ```bash
   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](cursor://anysphere.cursor-deeplink/mcp/install?name=mem0&config=eyJtY3BTZXJ2ZXJzIjp7Im1lbTAiOnsidXJsIjoiaHR0cHM6Ly9tY3AubWVtMC5haS9tY3AvIiwiaGVhZGVycyI6eyJBdXRob3JpemF0aW9uIjoiVG9rZW4gJHtlbnY6TUVNMF9BUElfS0VZfSJ9fX19)

**Option B — Manual configuration** (MCP server only):

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

```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](https://cursor.com/marketplace) for the complete experience including lifecycle hooks and the Mem0 SDK skill.

## Verify it works

After installing, confirm the MCP server is connected:

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