Installation

End Users

npm install -g @memtensor/memos-cloud-cli@beta

The npm package downloads a prebuilt MemOS CLI binary for the current platform during installation, so end users do not need a local Python environment.

Development

pip install -e .

Uninstall

memos uninstall --agent codex --yes
npm uninstall -g @memtensor/memos-cloud-cli

Run memos uninstall --agent <agent> --yes before removing the npm package. It removes the installed MemOS skill and cleans the managed MemOS block from agent guidance files such as AGENTS.md or CLAUDE.md; npm uninstall only removes the global binary.

See skills/memos-memory/references/memos-uninstall.md for the agent-facing uninstall workflow.

Quick Start

1. Initialize

memos init --agent codex

This command installs the bundled MemOS operation skill and writes the matching agent guidance. --agent is required, and installation to a generic global directory is not supported. --memos-plugin defaults to false. Set it to true when the target agent already has the MemOS memory plugin installed and should prefer plugin search/add flows. It also installs shell completion automatically for the current shell when shell detection succeeds.

Supported targets:

• --agent codex → ~/.codex/skills/memos/
• --agent cursor → ~/.cursor/skills/memos/
• --agent claude → ~/.claude/skills/memos/
• --agent openclaw → ~/.openclaw/skills/memos/
• --agent hermes → ~/.hermes/skills/memos/
• --agent trae → ~/.trae/skills/memos/
• --agent trae-cn → ~/.trae-cn/skills/memos/
• --agent opencode → ~/.config/opencode/skills/memos/
• --agent antigravity → ~/.gemini/antigravity/skills/memos/
• --agent workbuddy → ~/.codebuddy/skills/memos/
• --agent cline → ~/.cline/skills/memos/
• --agent copilot → ~/.copilot/skills/memos/

Or with arguments:

memos init --api-key YOUR_API_KEY --agent codex

2. Add Memory

memos add "User likes Python programming"

3. Search Memories

memos search "programming languages"

4. Chat with MemOS

memos chat "What do you know about my preferences?"

5. Get Memories

memos get user_123

6. Delete Memory

memos delete mem_123456

7. Get Memory Origin

memos origin mem_123456

Example output includes:

• API Key
• Base URL
• Source
• Framework
• default User ID and Conversation ID

Get/Set specific values:

memos config get platform.api_key
memos config set defaults.user_id user123

Environment Variables

• MEMOS_API_KEY: Your API key
• MEMOS_BASE_URL: API base URL (default: https://memos.memtensor.cn/api/openmem/v1)
• MEMOS_FRAMEWORK: Override framework attribution (for example codex)

Agent Integration

Use the provided skill to enable memory operations in your agent framework.

Use this skill when:

• you need memory operations such as extract, add, search, chat, get, and delete: skills/memos-memory/SKILL.md
• you need to remove the MemOS skill and managed agent guidance: skills/memos-memory/references/memos-uninstall.md

Recommended entry point:

1. Start with skills/memos-memory/SKILL.md.

Telemetry & Source Tracking

All CLI requests include:

• source=cli-<framework> header when the framework can be identified, for example source=cli-codex
• Framework detection (OpenClaw, Hermes, etc.)

Memory API requests also attach framework metadata when it can be detected from environment variables or the parent process.

This enables usage analytics and framework-specific optimizations.

Framework detection is resolved in this order:

• runtime override
• saved config value from memos init --agent ...
• MEMOS_FRAMEWORK
• shell / parent-process inference

Development

Run from source

python -m memos_cli --help

Add new commands

1. Create command file in src/memos_cli/commands/
