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

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"

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.

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:

mem0 init --email [email protected]

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.
