# Mem0 Plugin for Claude Code, Claude Cowork, Cursor, Codex, OpenCode & Antigravity
> **Claude Code users:** version 0.3.0 of the Claude Code plugin now lives at
> [`integrations/claude-code-plugin`](../claude-code-plugin/) and is what `mem0@mem0-plugins` installs.
> Update with `claude plugin marketplace update mem0-plugins` then
> `claude plugin update mem0@mem0-plugins --scope user` — your memories carry over
> automatically. This directory continues to serve the Cursor, Codex, Kimi,
> Antigravity, and OpenCode integrations until they are ported. The Claude Code
> manifest, hooks, and MCP config have been removed from this directory, so
> there is nothing here left to install into Claude Code.
Add persistent memory to your AI workflows. Store, retrieve, and manage memories across sessions using the Mem0 Platform. Works with **Claude Code** (CLI), **Claude Cowork** (desktop app), **Cursor**, **Codex**, **OpenCode**, and **Antigravity**.

**Cowork desktop app:** Open the Cowork tab, click **Customize** in the sidebar, click **Browse plugins**, and install Mem0.

- **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.
- **Lifecycle Hooks** — Automatic memory capture at key points. Claude Code, OpenCode, and Antigravity wire hooks natively when the full plugin is installed. Codex hooks are opt-in via a one-time installer (`scripts/install_codex_hooks.py`).

- **Mem0 SDK Skill** — Guides the AI on how to integrate the Mem0 SDK (Python & TypeScript) into your applications.
## Updating the plugin
When the plugin updates (new version pulled from the marketplace, or a fresh local install), the MCP server connection in your existing session is left holding a stale handle and stops responding. **Restart your client to reconnect:**
- **Claude Code:** run `/restart` in the prompt, or close and reopen the CLI.
- **Cursor:** quit and relaunch.
- **Codex:** restart the editor session.
- **OpenCode:** restart the session.
- **Antigravity:** restart the session.
Your `MEM0_API_KEY` doesn't need to be re-entered — the auth header is re-read from your environment on the new session. The plugin's MCP config uses `${MEM0_API_KEY}` interpolation at session start, not at install time, so as long as the env var is set persistently (in your shell profile or `~/.claude/settings.json` `env` block), reconnection is automatic on restart.

If reconnection still fails after a restart, check that `MEM0_API_KEY` is reachable in the new shell (`echo $MEM0_API_KEY`) and confirm you're using a key that starts with `m0-` (from https://app.mem0.ai/dashboard/api-keys, not a legacy token).
