# Supermemory MCP Server 4.0
A standalone MCP (Model Context Protocol) server for Supermemory that gives AI assistants persistent memory across conversations. Built on Cloudflare Workers with Durable Objects for scalable, persistent connections.
## Features
- **Authentication** - Supports both API keys and OAuth authentication
- **Persistent Memory** - Save and recall information across sessions
- **User Profiles** - Auto-generated profiles from stored memories
- **Project Scoping** - Organize memories by project with `x-sm-project` header
- **Analytics** - PostHog integration for usage tracking
## Setup
### Quick Install (Recommended)
```bash
npx -y install-mcp@latest https://mcp.supermemory.ai/mcp --client claude --oauth=yes
```
Replace `claude` with your MCP client: `claude`, `cursor`, `windsurf`, etc.
### Manual Configuration
Add to your MCP client config (Claude Desktop, Cursor, Windsurf, etc.):
```json
{
"mcpServers": {
"supermemory": {
"url": "https://mcp.supermemory.ai/mcp"
}
}
}
```
The server uses OAuth authentication by default. Your MCP client will automatically discover the authorization server via `/.well-known/oauth-protected-resource` and prompt you to authenticate.
### API Key Authentication (Alternative)
If you prefer to use an API key instead of OAuth, you can pass it directly in the `Authorization` header. Get your API key from [app.supermemory.ai](https://app.supermemory.ai):
```json
{
"mcpServers": {
"supermemory": {
"url": "https://mcp.supermemory.ai/mcp",
"headers": {
"Authorization": "Bearer sm_your_api_key_here"
}
}
}
}
```
API keys start with `sm_` and are automatically detected. When an API key is provided, OAuth authentication is skipped.
### Project Scoping (Optional)
To scope all operations to a specific project, add the `x-sm-project` header:
```json
{
"mcpServers": {
"supermemory": {
"url": "https://mcp.supermemory.ai/mcp",
"headers": {
"x-sm-project": "your-project-id"
}
}
}
}
```
## Tools
### `memory`
Save or forget information about the user.
```json
{
"content": "User prefers dark mode and uses TypeScript",
"action": "save",
"containerTag": "optional-project-tag"
}
```
| Parameter | Type | Required | Description |
|-----------|------|----------|-------------|
| `content` | string | Yes | The memory content to save or forget |
| `action` | `"save"` \| `"forget"` | No | Default: `"save"` |
| `containerTag` | string | No | Project tag to scope the memory |
### `recall`
Search memories and get user profile.
```json
{
"query": "What are the user's programming preferences?",
"includeProfile": true,
"containerTag": "optional-project-tag"
}
```
| Parameter | Type | Required | Description |
|-----------|------|----------|-------------|
| `query` | string | Yes | Search query to find relevant memories |
| `includeProfile` | boolean | No | Include user profile summary. Default: `true` |
| `containerTag` | string | No | Project tag to scope the search |
### `whoAmI`
Get the current logged-in user's information.
```json
{}
```
Returns: `{ userId, email, name, client, sessionId }`
## Resources
| URI | Description |
|-----|-------------|
| `supermemory://profile` | User profile with stable preferences and recent activity |
| `supermemory://projects` | List of available memory projects |
## Prompts
| Name | Description |
|------|-------------|
| `context` | User profile and preferences for system context injection |
## Development
### Prerequisites
- [Bun](https://bun.sh/) or Node.js
- [Wrangler CLI](https://developers.cloudflare.com/workers/wrangler/)
### Install Dependencies
```bash
bun install
```
### Environment Variables
Create a `.dev.vars` file:
```env
API_URL=http://localhost:8787
or
API_URL=https://api.supermemory.ai
```
| Variable | Description | Default |
|----------|-------------|---------|
| `API_URL` | Main Supermemory API URL for OAuth validation | `https://api.supermemory.ai` |
### Run Locally
```bash
bun run dev
```
The server will start at `http://localhost:8788`.
**Note:** For local development, you also need the main Supermemory API running at the `API_URL` for OAuth token validation.
### Deploy
```bash
bun run deploy
```
