Mem0 Plugin for Claude & Cursor

Add persistent memory to your AI coding workflows. Store, retrieve, and manage memories across sessions using the Mem0 Platform. Works with both Claude Code and Cursor.

Step 1: Set your API key

You must complete this step before installing the plugin for either Claude Code or Cursor.

1. Sign up at app.mem0.ai if you haven't already

2. Go to app.mem0.ai/dashboard/api-keys

3. Click Create API Key and copy the key (starts with m0-)

4. Add it to your shell profile:

   # For zsh (default on macOS)
   echo 'export MEM0_API_KEY="m0-your-api-key"' >> ~/.zshrc
   source ~/.zshrc
   
   # For bash
   echo 'export MEM0_API_KEY="m0-your-api-key"' >> ~/.bashrc
   source ~/.bashrc
   

5. Confirm it's set:

   echo $MEM0_API_KEY
   # Should print: m0-your-api-key
   

Step 2: Install the plugin

Choose one of the options below. Both require MEM0_API_KEY to be set first (see above).

Claude Code

/plugin marketplace add mem0ai/mem0
/plugin install mem0@mem0-plugins

Cursor

Click the deeplink below to install the Mem0 MCP server in Cursor:

Install Mem0 MCP in Cursor

Already have mem0 configured as an MCP server? Remove the existing entry from your .mcp.json or settings before installing this plugin to avoid duplicate tools.

Verify it works

After installing, confirm the MCP server is connected:

1. Start a new session (or restart your current one)
2. Ask: "List my mem0 entities" or "Search my memories for hello"
3. If the mem0 tools appear and respond, you're all set

What's included

• MCP Server — Connects to the Mem0 remote MCP server (mcp.mem0.ai), providing tools to add, search, update, and delete memories. No local dependencies required.
• Mem0 Skill — Guides Claude on how to integrate the Mem0 SDK (Python & TypeScript) into your applications
