# 4. MCP Persistence

Gives your Agent a **personal database** to save, organize, and retrieve information across different conversations and sessions.

This MCP is particularly useful for:

| Folder                 | What it holds                      |
| ---------------------- | ---------------------------------- |
| **Taking notes**       | General information and reminders  |
| **Selecting memories** | Past experiences, important events |
| **Preferences**        | User settings and habits           |
| **Conversations**      | Summaries of important chats       |

You can even use this MCP as a CRM to manage your prospects and current clients!

## Configuration parameters

This MCP doesn't require any parameters. The basic configuration is enough to start saving data.

### Custom parameters

No additional parameters needed.

## How to use MCP Persistence

Add instructions to tell the Agent, **what to save and when to retrieve** data.

**Practical examples:**

```
Save user preferences to the database using MCP Persistence whenever the user specifies them.
Before responding, check the database for any existing information about the current user.
```

Imagine your AI assistant as your own  **personal secretary**.

With MCP Persistence, this secretary now has a **filing cabinet**. They can write things down, look things up, and come back with fully prepared answers
