[supermemory](https://github.com/supermemoryai/claude-supermemory) is a Claude Code plugin that gives your AI persistent memory across sessions. Your agent remembers what you worked on — across sessions, across projects.

<Tip>
**Prefer to keep everything on your machine?** This plugin works with [self-hosted Supermemory](/self-hosting/overview) — run `npx supermemory local`, then set `baseUrl` in project config (or point your install at your local API) and use the API key printed on first boot.
</Tip>

## Install the plugin

> **Requires Node.js 18+** on your PATH — the memory hooks run as Node scripts.

```bash
# Add the plugin marketplace
/plugin marketplace add supermemoryai/claude-supermemory

# Install the plugin
/plugin install supermemory
```

<Note>
**Migrating from the old `claude-supermemory` plugin name?** It was renamed to `supermemory` and will not update in place:

```bash
/plugin marketplace update supermemory-plugins
/plugin install supermemory@supermemory-plugins
# Only if the old plugin is still installed:
/plugin uninstall claude-supermemory@supermemory-plugins
```
</Note>

## Authenticate

Start a Claude Code session and the plugin opens a browser login, then saves the key to `~/.supermemory-claude/credentials.json`.

Or create a Supermemory API key from the [API Keys](https://console.supermemory.ai/keys) page in the console and add it to your shell profile:

<Tabs>
  <Tab title="macOS / Linux (zsh)">
    ```bash
    echo 'export SUPERMEMORY_CC_API_KEY="sm_..."' >> ~/.zshrc
    source ~/.zshrc
    ```
  </Tab>
  <Tab title="macOS / Linux (bash)">
    ```bash
    echo 'export SUPERMEMORY_CC_API_KEY="sm_..."' >> ~/.bashrc
    source ~/.bashrc
    ```
  </Tab>
  <Tab title="Windows (PowerShell)">
    ```powershell
    [System.Environment]::SetEnvironmentVariable("SUPERMEMORY_CC_API_KEY", "sm_...", "User")
    ```
    Restart your terminal after running this.
  </Tab>
</Tabs>

## How it works

Once installed, the plugin runs automatically:

- **Session context** — At session start, profile facts for this project are loaded into context.
- **Direct recall** — Before Claude sees each substantive prompt, the hook searches Supermemory and injects fresh matches. Set `recallDirective` to switch to advisory mode, where Claude decides when to search.
- **Auto-capture** — After each Claude response (the Stop hook), conversation content added since the last save is captured in the background.
- **Shared repo memory** — Captures go to one repository container shared with the Codex, OpenCode, and Cursor plugins, tagged with `sm_scope: personal` metadata.
- **MCP tools** — The hosted Supermemory MCP tools (`search_memory`, `add_memory`, and more) use the same credentials. `search_memory` and the legacy camelCase read tools (`listMemories`, `listDocuments`, `getDocument`, `listSpaces`, `whoAmI`) are approved automatically; other tools, including `list_memories`, `list_documents`, `get_document` and `get_profile`, still ask for approval. For deeper history, Claude can also use the `context-gatherer` agent.

## Commands

| Command | Description |
| --- | --- |
| `/supermemory:index` | Index codebase architecture, conventions, and how to run it into the project container |
| `/supermemory:status` | Show authentication status, API and MCP reachability, and the active project container |

## Configuration

### Environment variables

```bash
SUPERMEMORY_CC_API_KEY=sm_...        # Optional: browser login is used when unset
SUPERMEMORY_API_URL=...              # Optional: override the REST API base URL
SUPERMEMORY_REPO_TAG=...             # Optional: override the project container
SUPERMEMORY_ISOLATE_WORKTREES=true   # Optional: key the container on the worktree path
SUPERMEMORY_DEBUG=true               # Optional: enable debug logging
```

### Global settings

Create `~/.supermemory-claude/settings.json`:

```json
{
  "maxProfileItems": 5,
  "signalExtraction": true,
  "signalKeywords": ["remember", "architecture", "decision", "bug", "fix"],
  "signalTurnsBefore": 3,
  "includeTools": ["Edit", "Write"]
}
```

| Option | Description |
| --- | --- |
| `maxProfileItems` | Max memories in context (default: 5) |
| `recallDirective` | Override the built-in reasoned-recall instruction |
| `signalExtraction` | Only capture important turns (default: false) |
| `signalKeywords` | Keywords that trigger capture |
| `signalTurnsBefore` | Context turns before a signal (default: 3) |
| `includeTools` | Tools to explicitly capture |

### Project config

Per-repo overrides in `.claude/.supermemory-claude/config.json`. Create the file manually:

```json
{
  "apiKey": "sm_...",
  "baseUrl": "https://api.supermemory.ai",
  "namespace": "my-team-project",
  "signalExtraction": true
}
```

| Option | Description |
| --- | --- |
| `apiKey` | Project-specific API key |
| `baseUrl` | Supermemory API URL (use for self-hosted) |
| `apiVersion` | `v5` or `legacy`. The hosted API uses v5; custom `baseUrl` values default to `legacy`. Set `v5` to use v5 with a self-hosted server 0.0.9 or newer |
| `namespace` | Override the project container. Takes precedence over `repoContainerTag` |
| `repoContainerTag` | Override the project container (checked before `SUPERMEMORY_REPO_TAG`) |

API key precedence is `SUPERMEMORY_CC_API_KEY`, project `apiKey`, then `~/.supermemory-claude/credentials.json`.
