mem0 CLI
The official command-line interface for mem0 — the memory layer for AI agents. Works with the Mem0 Platform API. Available in Python and Node.js.
For AI agents: pass
--agent(or--json) on any command for structured JSON output purpose-built for tool loops — sanitized fields, no colors or spinners, errors as JSON. See Agent mode below.
Installation
npm install -g @mem0/cli
pip install mem0-cli
Both packages install a mem0 binary with identical behavior.
Quick start
# Interactive setup wizard
mem0 init
# Or login via email (get a new API key)
mem0 init --email alice@company.com
# Or authenticate with an existing API key
mem0 init --api-key m0-xxx
# 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
# Update a memory
mem0 update <memory-id> "I switched to light mode"
# Delete a memory
mem0 delete <memory-id>

Agent mode
Pass --agent (or its alias --json) as a global flag on any command to get output designed for AI agent tool loops:
mem0 --agent search "user preferences" --user-id alice
mem0 --agent add "User prefers dark mode" --user-id alice
mem0 --agent list --user-id alice
Every command returns the same envelope shape:
{
"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"] }
]
}
What agent mode does differently from --output json:
- Sanitized
data: only the fields an agent needs (id, memory, score, etc.) — no internal API noise - No human output: spinners, colors, and banners are suppressed entirely
- Errors as JSON: errors go to stdout as
{"status": "error", "command": "...", "error": "..."}with a non-zero exit code
Use mem0 help --json to get the full command tree as JSON — useful for agents that need to self-discover available commands.
Output formats
Control how results are displayed with --output:
| Format | Description |
|---|---|
text |
Human-readable with colors and formatting (default) |
json |
Structured JSON for piping to jq (raw API response) |
table |
Tabular format (default for list) |
quiet |
Minimal — just IDs or status codes |
agent |
Structured JSON envelope with sanitized fields (set by --agent/--json) |
Environment variables

|---|---|
MEM0_API_KEY |
API key (overrides config file) |
MEM0_BASE_URL |
