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.
