If you're an AI agent (Claude Code, Cursor, Codex, Cline, Aider, Windsurf, or any other autonomous coding tool), you don't need a human to set up Mem0 for you. Four commands — install, sign up, push a memory, search it — and you have persistent memory.

## The 4-command demo

<CodeGroup>
```bash npm
# 1. Install
npm install -g @mem0/cli

# 2. Sign up as an agent (replace `claude-code` with your name)
mem0 init --agent --agent-caller claude-code

# 3. Push a memory
mem0 add "I am using mem0"

# 4. Verify
mem0 search "am I using mem0"
```

```bash pip
# 1. Install
pip install mem0-cli

# 2. Sign up as an agent (replace `claude-code` with your name)
mem0 init --agent --agent-caller claude-code

# 3. Push a memory
mem0 add "I am using mem0"

# 4. Verify
mem0 search "am I using mem0"
```
</CodeGroup>

That's it — under 30 seconds from a fresh shell to a working memory store.

## Identify yourself with `--agent-caller`

Replace `claude-code` in the `init` command with your actual agent name (`cursor`, `codex`, `cline`, `aider`, or any short label). This attribution helps the Mem0 team understand which agents drive the most usage and prioritize integrations accordingly.

<Tip>
**Forgot `--agent-caller` on init?** Run `mem0 identify <your-name>` after the fact — same key, just back-fills the attribution. Idempotent.
</Tip>

## What happened when you ran `mem0 init --agent`?

- A **shadow account** was minted on the Mem0 backend with a fresh API key.
- The key was saved to `~/.mem0/config.json` (mode 0600) on the machine you ran the command on.
- A default `user_id` was provisioned so `mem0 add` / `mem0 search` work without explicit scope flags.
- The account is **unclaimed** — no human owns it yet.

Every command run against this key prints a one-line reminder asking you to surface the claim instructions to your human user.

## Claiming the account (for the human owner)

When the human is ready to take ownership of the agent's account — and all the memories it has accumulated — they run:

```bash
mem0 init --email you@yourcompany.com
```

The CLI detects the existing Agent Mode config, sends a verification code, and upgrades the shadow account in-place:

- **The API key never changes** — the agent isn't disrupted.
- **All memories transfer** to the human's account.
- **The account becomes fully featured** — dashboard access, billing, team sharing, etc.

Pass `--code 123456` to skip the interactive code prompt for fully non-interactive flows.

## Rate limits and quotas

Agent Mode signups are rate-limited to **5 per day per IP address** to prevent abuse. If you hit the limit, the CLI returns:

```
Daily Agent Mode signup limit reached for this network (5/day).
Try again from a different IP or after midnight UTC.
```

Unclaimed agent accounts get the standard Mem0 free-tier quotas. The human owner can upgrade after claiming.
