## Setup

## Setup
Add this to your claude_desktop_config.json:

```json
{
  "mcpServers": {
    "memory": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-memory"
      ]
    }
  }
}
```

You can specify a custom path for the memory file:

```json
{
  "mcpServers": {
    "memory": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-memory", "--memory-path", "/path/to/your/memory.jsonl"]
    }
  }
}
```

If no path is specified, it will default to memory.jsonl in the server's installation directory.

The prompt for utilizing memory depends on the use case and an example prompt for chat personalization is provided.
