> Model Context Protocol (MCP) provides a standardized way for AI agents to manage their own memory through Mem0, without manual API calls.

## Why use MCP

When building AI applications, memory management often requires manual integration. MCP eliminates this complexity by:

- **Universal compatibility**: Works with any MCP-compatible client (Claude, Claude Code, Cursor, Windsurf, VS Code, OpenCode)
- **Agent autonomy**: AI agents decide when to save, search, or update memories
- **Zero infrastructure**: No servers to maintain - Mem0's cloud MCP handles everything
- **Standardized protocol**: One integration works across all your AI tools

## Setup

Add Mem0 MCP to all supported 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"
```

Or configure a specific client:

```bash
npx mcp-add \
  --name mem0-mcp \
  --type http \
  --url "https://mcp.mem0.ai/mcp" \
  --clients "cursor"
```

For manual configuration, add this to your MCP client config:

```json
{
  "mcpServers": {
    "mem0-mcp": {
      "type": "http",
      "url": "https://mcp.mem0.ai/mcp"
    }
  }
}
```

For detailed per-client instructions, see the [Mem0 MCP Quickstart](/platform/mem0-mcp).

## Available tools

The MCP server exposes 11 memory tools to your AI client:

| Tool | Purpose |
|------|---------|
| `add_memory` | Store conversations or facts |
| `search_memories` | Find relevant memories with filters |
| `get_memories` | List memories with pagination |
| `update_memory` | Modify existing memory content |
| `delete_memory` | Remove specific memories |
| `delete_all_memories` | Bulk delete memories |
| `delete_entities` | Remove user/agent/app entities |
| `get_memory` | Retrieve single memory by ID |
| `list_entities` | View stored entities |
| `list_events` | List memory operation events with filters and pagination |
| `get_event_status` | Check the status of an async memory operation by `event_id` |

## How it works

1. **Configure the MCP server** - Add Mem0 MCP to your AI client using the setup command above
2. **Agent connects** - Your AI client connects to Mem0's cloud MCP server over HTTP
3. **Autonomous memory** - The agent decides when to store/retrieve memories as part of its reasoning
4. **No manual API calls** - The agent manages memory automatically through MCP tools

## Example interactions

Once connected, your AI agent can:

```
User: Remember that I'm allergic to peanuts
Agent: [calls add_memory] Got it! I've saved your peanut allergy.

User: What dietary restrictions do I know about?
Agent: [calls search_memories] You have a peanut allergy.
```

The agent automatically decides when to use memory tools based on context.

## Try these prompts

```python
# Multi-task operations
"Generate 5 user personas for our e-commerce app with different demographics, store them all, then search for existing personas"

# Natural context retrieval
"Anything about my work preferences I should remember?"

# Complex information updates
"Update my current project: the mobile app is now 80% complete, we've fixed the login issues, and the launch date is March 15"

# Time-based queries
"What meetings did I have last week about Project Phoenix?"

# Memory cleanup
"Delete all test data and temporary memories from our development phase"

# Personal preferences
"I drink oat milk cappuccino with one sugar every morning, and I prefer standing desks"

# Health and wellness tracking
"I'm allergic to peanuts and shellfish, and I go for 5km runs on weekday mornings"
```

These examples demonstrate how MCP enables natural language memory operations - the AI agent automatically determines when to add, search, update, or delete memories based on context.

## What you can do

The Mem0 MCP server enables powerful memory capabilities for your AI applications:

- **Health tracking**: "I'm allergic to peanuts and shellfish" - Add new health information
- **Research data**: "Store these trial parameters: 200 participants, double-blind, placebo-controlled" - Save structured data
- **Preference queries**: "What do you know about my dietary preferences?" - Search and retrieve relevant memories
- **Project updates**: "Update my project status: the mobile app is now 80% complete" - Modify existing memory
- **Data cleanup**: "Delete all memories from 2023" - Bulk remove outdated information
- **Topic overview**: "Show me everything about Project Phoenix" - List all memories for a subject

## Performance tips

- Enable graph memories for relationship-aware recall
- Use specific filters when searching large memory sets
- Batch operations when adding multiple memories
- Monitor memory usage in the Mem0 dashboard

## Best practices

- **Use the cloud MCP**: The hosted MCP server at `https://mcp.mem0.ai/mcp` handles infrastructure for you
- **Use wildcards**: `user_id: "*"` to search across all users
- **Monitor usage**: Track memory operations in the dashboard
- **Document patterns**: Share successful prompt patterns with your team
