title: CLI
description: "Manage memories from your terminal — built for both humans and AI agents."
icon: "terminal"
iconType: "solid"
---
The mem0 CLI lets you add, search, list, update, and delete memories directly from the terminal. It works with the Mem0 Platform API and is available as both an npm package and a Python package.
Both implementations provide identical behavior — same commands, same options, same output formats.
<Tip>
**Built for AI agents.** Pass `--agent` (or `--json`) as a global flag on any command to get structured JSON output optimized for programmatic consumption — sanitized fields, no colors or spinners, and errors as JSON too. Drop it into any agent tool loop with zero extra parsing.
</Tip>
## Installation
<CodeGroup>
```bash npm
npm install -g @mem0/cli
```
```bash pip
pip install mem0-cli
```
</CodeGroup>
## Authentication
Run the interactive setup wizard to configure your API key:
```bash
mem0 init
```
This prompts for your API key and a default user ID, validates the connection, and saves the configuration locally.
For CI/CD or non-interactive environments, pass both values as flags:
```bash
mem0 init --api-key m0-xxx --user-id alice
```
You can also set your API key via environment variable:
```bash
export MEM0_API_KEY="m0-xxx"
```
## Quick start
```bash
# Add a memory
mem0 add "I prefer dark mode and use vim keybindings" --user-id alice
# Search memories
mem0 search "What are Alice's preferences?" --user-id alice
# List all memories for a user
mem0 list --user-id alice
# Get a specific memory
mem0 get <memory-id>
# Update a memory
mem0 update <memory-id> "I prefer light mode now"
# Delete a memory
mem0 delete <memory-id>
```
## Commands
### `mem0 init`
Interactive setup wizard. Prompts for your API key and default user ID.
```bash
mem0 init
mem0 init --api-key m0-xxx --user-id alice
mem0 init --email alice@company.com
```
If an existing configuration is detected, the CLI will ask for confirmation before overwriting. Use `--force` to skip the prompt (useful in CI/CD pipelines).
```bash
mem0 init --api-key m0-xxx --user-id alice --force
```
| Flag | Description |
|------|-------------|
| `--api-key` | API key (skip prompt) |
| `-u, --user-id` | Default user ID (skip prompt) |

| `--code` | Verification code (use with `--email` for non-interactive login) |
| `--force` | Overwrite existing config without confirmation |
### `mem0 add`
Add a memory from text, a JSON messages array, a file, or stdin.
```bash
mem0 add "I prefer dark mode" --user-id alice
mem0 add --file conversation.json --user-id alice
echo "Loves hiking on weekends" | mem0 add --user-id alice

### `mem0 search`
Search memories using natural language.
```bash
mem0 search "dietary restrictions" --user-id alice

### `mem0 list`
List memories with optional filters and pagination.
```bash
mem0 list --user-id alice
mem0 list --user-id alice --category preferences --output json
mem0 list --user-id alice --after 2024-01-01 --page-size 50
```
| Flag | Description |

mem0 delete <memory-id>
# Delete all memories for a user
mem0 delete --all --user-id alice --force
# Delete all memories project-wide
mem0 delete --all --project --force
# Preview what would be deleted
mem0 delete --all --user-id alice --dry-run
```

| `--all` | Delete all memories matching scope filters |
| `--entity` | Delete the entity and all its memories |

The file should be a JSON array where each item has a `memory` (or `text` or `content`) field and optional `user_id`, `agent_id`, and `metadata` fields.
### `mem0 config`
View or modify the local CLI configuration.
```bash
mem0 config show # Display current config (secrets redacted)
mem0 config get api_key # Get a specific value
mem0 config set user_id bob # Set a value
```
### `mem0 entity`
List or delete entities (users, agents, apps, runs).
```bash
mem0 entity list users
mem0 entity list agents --output json
mem0 entity delete --user-id alice --force
```
### `mem0 event`
Inspect background processing events created by async operations (e.g. bulk deletes, large add jobs).
```bash
# List recent events
mem0 event list
# Check the status of a specific event
mem0 event status <event-id>
```
| Flag | Description |
|------|-------------|
| `-o, --output` | Output format: `text`, `json` |
### `mem0 status`
Verify your API connection and display the current project.
```bash
mem0 status
```
### `mem0 version`

```
## Output formats
All commands support the `--output` flag to control how results are displayed:
| Format | Description |
|--------|-------------|
| `text` | Human-readable output with colors and formatting (default for most commands) |
| `json` | Structured JSON, suitable for piping to `jq` or consumption by AI agents |
| `table` | Tabular format (default for `list`) |
| `quiet` | Minimal output — just IDs or status codes |
| `agent` | Structured JSON envelope with sanitized fields — set automatically by `--json`/`--agent` |
Example with JSON output:
```bash
mem0 search "user preferences" --user-id alice --output json | jq '.data.results[].memory'
```
## Use with AI agents
The CLI is purpose-built for use inside AI agent tool loops. Pass `--agent` or `--json` as a global flag on **any** command to activate agent mode:
- Every command outputs a consistent JSON envelope: `{"status", "command", "duration_ms", "scope", "count", "data"}`
- The `data` field contains only the fields that matter — IDs, memory text, scores, categories. Noisy API fields are stripped.
- All human-readable output is suppressed: no spinners, no colors, no banners.
- Errors are returned as JSON to stdout with a non-zero exit code, so your agent can catch them the same way as successes.
```bash
# Drop --agent on any command and get clean, parseable JSON
mem0 --agent search "response preferences" --user-id user-42
mem0 --agent add "User prefers concise responses" --user-id user-42
mem0 --agent list --user-id user-42
mem0 --agent delete --all --user-id user-42 --force
```
<CodeGroup>
```json Output: mem0 --agent search "dark mode" --user-id alice
{
"status": "success",
"command": "search",
"duration_ms": 134,
"scope": { "user_id": "alice" },
"count": 2,
"data": [
{ "id": "abc-123", "memory": "User prefers dark mode", "score": 0.97, "created_at": "2026-01-15", "categories": ["preferences"] },
{ "id": "def-456", "memory": "User uses vim keybindings", "score": 0.81, "created_at": "2026-01-10", "categories": ["tools"] }
]
}
```
```json Output: mem0 --agent add "Likes concise answers" --user-id alice
{
"status": "success",
"command": "add",
"duration_ms": 210,
"data": [
{ "id": "ghi-789", "memory": "Likes concise answers", "event": "ADD" }
]
}
```
</CodeGroup>
Two other agent-friendly features:
- **`--output json`** returns structured data without sanitization — useful when you want the full raw API response
- **`mem0 help --json`** returns the complete command tree as JSON, so agents can self-discover available commands and options
For non-interactive environments (CI, agent runtimes), set credentials via `mem0 init --api-key m0-xxx --user-id alice --force` or the `MEM0_API_KEY` environment variable.
## Environment variables
| Variable | Description |
|----------|-------------|
| `MEM0_API_KEY` | API key (overrides config file) |
| `MEM0_BASE_URL` | API base URL |
| `MEM0_USER_ID` | Default user ID |
| `MEM0_AGENT_ID` | Default agent ID |
| `MEM0_APP_ID` | Default app ID |
| `MEM0_RUN_ID` | Default run ID |
| `MEM0_ENABLE_GRAPH` | Enable graph memory (`true` / `false`) |
Environment variables take precedence over values in the config file, which take precedence over defaults.
## Global flags
These flags are available on all commands:
| Flag | Description |
|------|-------------|
| `--json` | Enable agent mode: structured JSON envelope output, no colors or spinners |
| `--agent` | Alias for `--json` |
| `--api-key` | Override the configured API key for this request |
| `--base-url` | Override the configured API base URL for this request |
| `-o, --output` | Set the output format |
