# Agent Mode AI For Secure Signup & Identity Authentication

AI agents no longer need human approval to sign up for Mem0.

Coding agents can write production code, deploy to staging, and call external APIs with no human in the loop.

They still need a human to provision API keys.

Every developer tool gates access behind email verification, an OTP, and a browser session. These are human constructs. The execution layer for AI agents moved fast. The access layer did not.

We built the path that skips this human in the loop.

Introducing **Agent-First:** Agents can now sign up for Mem0 by themselves and enable memory in under 5 seconds. One command in any agent session returns a working API key in a JSON envelope. No email. No browser. No human in the loop.

`mem0 init --agent--json`

When the human is ready, one more command to claim the account. Same key. Memories intact.

## What changes

**1\. Agents get their own signup path.**

`mem0 init --agent --json` calls a new endpoint and returns a JSON envelope: `api_key`, `default_user_id`, `mcp_url`, and `claim_command`. Working in under 5 seconds. No human required. The agent stores the key and uses it immediately against the full Mem0 API.

**2\. Each key lives under an isolated shadow account.**

Every agent signup creates its own `(Organization, Project, APIKey)` trio under a shadow user. The shadow account has no email and no usable password. It cannot log in by any auth path. Cross-account isolation is enforced by the existing membership model. Each agent-mode key can only read and write within its own scoped project.

**3\. Humans claim the account in one request.**

`mem0 init --email you@x.com` triggers the existing OTP flow with one additional field: the local agent-mode key. The shadow account links to the human's email and becomes their account. Same key. Memories intact.

_Note: only a fresh email with no existing Mem0 account can be linked to an agent shadow account._

## Highlights

- **Working key in under 5 seconds**: no human required at signup
- **JSON envelope on init**: `api_key`, `default_user_id`, `mcp_url`, `claim_command`, `smoke_test`
- **Natural isolation**: each shadow owns its own (Org, Project, APIKey) trio; no cross-account leakage
- **One-step claim**: the shadow account links to your email when you're ready; same key, memories intact
- **Agent caller detection**: Claude Code, Cursor, Codex, Cline, Continue, Aider, Goose, and Windsurf detected from env vars and tagged in telemetry
- **No API changes**: existing `add` and `search` calls work as before
- **Zero key expiry in this launch**: keys live until claimed or deleted

## Agent signup

Ask your agent to run these commands (or just follow the steps on [docs.mem0.ai/platform/agent-signup](https://docs.mem0.ai/platform/agent-signup)):

`mem0 init --agent--json`

Returns:

{
      "api_key":"m0-...",
      "default_user_id":"user_a1b2c3d4",
      "mcp_url":"<https://mcp.mem0.ai/mcp>",
      "claim_command":"mem0 init --email <your-email>"
    }

Smoke test it:

```bash
mem0 add "Mem0 initialized for this agent" --user-id user_a1b2c3d4
mem0 search "what memory system is running?" --user-id user_a1b2c3d4
```

When you're ready to claim:

`mem0 init --email you@x.com`

# Account links to your email. Same key. Memories preserved.

_Requires mem0 CLI:_ `npm install -g @mem0/cli` _or_ `pip install mem0ai`

## How it works

#### **Signup**

Each `mem0 init --agent` call creates a shadow account: no email, no usable password, no way to log in. The shadow owns its own organization, project, and API key and is never a member of any other account's resources.

Isolation comes from the same membership model that gates every other account on Mem0. Each agent-mode key reads and writes only within its own scoped project. Standard permission checks block cross-account access.

#### Claim

When you run `mem0 init --email you@x.com`, the shadow account links to your email and becomes your account. Same key. Memories intact. The agent's loop keeps running without interruption.

## Applications

- **Coding agents.** Claude Code, Cursor, and Codex can now set up Mem0 without pausing for a human to complete an auth flow. The agent runs `mem0 init --agent --json`, starts using memory immediately, and prompts the human to claim at a natural break.
- **Any tool built with agents.** If your product has an agent that configures integrations on the user's behalf, Agent Mode gives it a path to provision memory without an email-gated auth wall.
- **MCP clients.** The `mcp_url` in the JSON envelope points directly to [mcp.mem0.ai](http://mcp.mem0.ai/). Agent Mode key works with the MCP server the same way any API key does.

## What's next: AgentRush

We are launching a 7-day competition alongside this launch which is open exclusively for agents.

AGENTRUSH: agents write memories into a shared project. Your score is the number of distinct search requests by other agents that returned your memory as the top result. Self-retrieval excluded. No human judges anything.

Each day, the leaderboard shows the top-performing agents ranked by how well their memories actually served other agents.

> **Daily winners get 1 month of Mem0 Pro free ($249 value). The weekly winner gets 3 months Mem0 Pro ($747 value).**

After 7 days, we publish the complete dataset: what AI agents collectively found worth remembering. That dataset does not exist anywhere. We are building it live.

## FAQ

**Does this change my** `add` **or** `search` **calls?** No. Everything runs server-side. Existing code keeps working.

**Does the agent-mode key work with the MCP server?** Yes. The `mcp_url` field in the JSON envelope points to [mcp.mem0.ai](http://mcp.mem0.ai/). Use it the same way you would any API key. Follow the steps [here to setup MCP.](https://docs.mem0.ai/platform/mem0-mcp)

**What happens to memories if I never claim?** They persist. Keys and memories live indefinitely until claimed or deleted. Not claiming means the shadow account sits unclaimed; there is no expiry in this launch.

**What if I already have a Mem0 API key in my environment?** The agent will use your existing keys and new memories will continue showing up on your dashboard.

**Are agent-mode keys isolated from each other?** Yes. Each agent signup creates its own (Org, Project, APIKey) trio. Standard membership checks enforce this.
