  **Prerequisites**
  - Mem0 Platform account (<a href="https://app.mem0.ai" rel="nofollow">Sign up here</a>)
  - API key (<a href="https://app.mem0.ai/settings/api-keys" rel="nofollow">Get one from dashboard</a>)
  - Node.js 14+ (for npx)
  - An MCP-compatible client (Claude, Claude Code, Cursor, Windsurf, VS Code, OpenCode)

## What is Mem0 MCP?

Mem0 MCP Server exposes Mem0's memory capabilities as MCP tools, letting AI agents decide when to save, search, or update information. The cloud-hosted MCP server requires no local installation — just connect and start using memory.

## Quick Setup

Add Mem0 MCP to your preferred clients with a single command:

```bash
npx mcp-add \
  --name mem0-mcp \
  --type http \
  --url "https://mcp.mem0.ai/mcp" \
  --clients "claude,claude code,cursor,windsurf,vscode,opencode"
```

This automatically configures Mem0 MCP for all supported clients at once.

## Available Tools

The MCP server exposes these memory tools to your AI client:

| Tool | Description |
|------|-------------|
| `add_memory` | Save text or conversation history for a user/agent |
| `search_memories` | Semantic search across existing memories with filters |
| `get_memories` | List memories with structured filters and pagination |
| `get_memory` | Retrieve one memory by its `memory_id` |
| `update_memory` | Overwrite a memory's text after confirming the ID |
| `delete_memory` | Delete a single memory by `memory_id` |
| `delete_all_memories` | Bulk delete all memories in scope |
| `delete_entities` | Delete a user/agent/app/run entity and its memories |
| `list_entities` | Enumerate users/agents/apps/runs stored in Mem0 |

## Client-Specific Setup

You can also configure individual clients:

<AccordionGroup>
  <Accordion title="Claude Desktop">
    ```bash
    npx mcp-add \
      --name mem0-mcp \
      --type http \
      --url "https://mcp.mem0.ai/mcp" \
      --clients "claude"
    ```

    Or manually add to your Claude Desktop configuration (`claude_desktop_config.json`):
    ```json
    {
      "mcpServers": {
        "mem0-mcp": {
          "type": "http",
          "url": "https://mcp.mem0.ai/mcp"
        }
      }
    }
    ```
  </Accordion>

  <Accordion title="Claude Code">
    ```bash
    npx mcp-add \
      --name mem0-mcp \
      --type http \
      --url "https://mcp.mem0.ai/mcp" \
      --clients "claude code"
    ```
  </Accordion>

  <Accordion title="Cursor">
    ```bash
    npx mcp-add \
      --name mem0-mcp \
      --type http \
      --url "https://mcp.mem0.ai/mcp" \
      --clients "cursor"
    ```

    Or go to Cursor → Settings → MCP and add:
    ```json
    {
      "mcpServers": {
        "mem0-mcp": {
          "type": "http",
          "url": "https://mcp.mem0.ai/mcp"
        }
      }
    }
    ```
  </Accordion>

  <Accordion title="Windsurf">
    ```bash
    npx mcp-add \
      --name mem0-mcp \
      --type http \
      --url "https://mcp.mem0.ai/mcp" \
      --clients "windsurf"
    ```
  </Accordion>

  <Accordion title="VS Code">
    ```bash
    npx mcp-add \
      --name mem0-mcp \
      --type http \
      --url "https://mcp.mem0.ai/mcp" \
      --clients "vscode"
    ```
  </Accordion>

  <Accordion title="OpenCode">
    ```bash
    npx mcp-add \
      --name mem0-mcp \
      --type http \
      --url "https://mcp.mem0.ai/mcp" \
      --clients "opencode"
    ```
  </Accordion>
</AccordionGroup>

## Verify Your Setup

Once configured, your AI client can:
- Automatically save information with `add_memory`
- Search memories with `search_memories`
- Update memories with `update_memory`
- Delete memories with `delete_memory`

**Sample Interactions:**

```
User: Remember that I love tiramisu
Agent: Got it! I've saved that you love tiramisu.

User: What do you know about my food preferences?
Agent: Based on your memories, you love tiramisu.

User: Update my project: the mobile app is now 80% complete
Agent: Updated your project status successfully.
```

## Quick Recovery

- **"Connection refused"** → Check your internet connection and ensure the MCP client is correctly configured
- **"Invalid API key"** → Get a new key from <a href="https://app.mem0.ai/settings/api-keys" rel="nofollow">Mem0 Dashboard</a>
- **"npx command not found"** → Install Node.js from [nodejs.org](https://nodejs.org)
