+# mem0 CLI
+
+The official command-line interface for [mem0](https://mem0.ai) — the memory layer for AI agents. Works with the Mem0 Platform API. Available in Python and Node.js.
+
+## Installation
+
+```bash
+npm install -g @mem0/cli
+```
+
+```bash
+pip install mem0-cli
+```
+
+Both packages install a `mem0` binary with identical behavior.
+
+## Quick start
+
+```bash
+# 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>
+```
+
+## Commands
+
+| Command | Description |
+|---------|-------------|
+| `mem0 init` | Setup wizard — login via email or configure API key manually |
+| `mem0 add` | Add a memory from text, JSON messages, a file, or stdin |
+| `mem0 search` | Search memories using natural language |
+| `mem0 list` | List memories with optional filters and pagination |
+| `mem0 get` | Retrieve a specific memory by ID |
+| `mem0 update` | Update the text or metadata of a memory |
+| `mem0 delete` | Delete a memory, all memories for a scope, or an entity |
+| `mem0 import` | Bulk import memories from a JSON file |
+| `mem0 config` | View or modify CLI configuration |
+| `mem0 entities` | List or delete entities (users, agents, apps) |
+| `mem0 status` | Verify API connection and display current project |
+| `mem0 version` | Print the CLI version |
+
+Run `mem0 <command> --help` for detailed usage on any command.
+
+## 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` or agent consumption |
+| `table` | Tabular format (default for `list`) |
+| `quiet` | Minimal — just IDs or status codes |
+
+```bash
+mem0 search "preferences" --user-id alice --output json | jq '.data.results[].memory'
+```
+
+## Environment variables
+
+| Variable | Description |

+
+- Node.js **18+**
+- pnpm (`npm install -g pnpm`)
+
+## Installation
+
+```bash
+npm install -g @mem0/cli
+```
+
+Or from source:
+
+```bash
+cd node
+pnpm install
+pnpm build
+pnpm link --global
+
+# Now use it like a normal CLI
+mem0 --help
+```
+
+## Running during development
+
+```bash
+cd node
+pnpm install
+
+# Development mode (runs TypeScript directly, no build needed)
+pnpm dev --help
+pnpm dev add "test memory" --user-id alice
+pnpm dev search "test" --user-id alice
+
+# Or build first, then run the compiled JS
+pnpm build
+node dist/index.js --help
+node dist/index.js add "test memory" --user-id alice
+```
+
+## Quick Start
+
+```bash
+# Set up your configuration
+mem0 init
+
+# 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
+mem0 list --user-id alice
+```
+
+## Environment Variables

+| `MEM0_API_KEY` | API key (overrides config file) |
+| `MEM0_BASE_URL` | API base URL |
+| `MEM0_USER_ID` | Default user ID |
+| `MEM0_AGENT_ID` | Default agent ID |
+| `MEM0_APP_ID` | Default app ID |
+| `MEM0_RUN_ID` | Default run ID |
+| `MEM0_ENABLE_GRAPH` | Enable graph memory (true/false) |

+# Development
+
+## Prerequisites
+
+- Node.js **18+**
+- pnpm (`npm install -g pnpm`)
+
+## Setup
+
+From the `node/` directory:
+
+```bash
+pnpm install
+```
+
+## Running the CLI
+
+There are two ways to run the CLI during development:
+
+### Option 1: Development mode (no build needed)
+
+Uses `tsx` to run TypeScript directly. Pass CLI arguments after `pnpm dev`:
+
+```bash
+pnpm dev --help
+pnpm dev version
+pnpm dev add "test memory" --user-id alice
+pnpm dev search "test" --user-id alice
+pnpm dev config show
+```
+
+> **Note:** Do NOT use `pnpm dev -- --help`. With pnpm, arguments pass through directly — adding `--` inserts a literal `--` that breaks the CLI parser.
+
+### Option 2: Build and run compiled JS
+
+```bash
+# Build first
+pnpm build
+
+# Run the compiled CLI
+node dist/index.js --help
+node dist/index.js version
+node dist/index.js add "test memory" --user-id alice
+```
+
+### Option 3: Link globally (makes `mem0` available system-wide)
+
+```bash
+pnpm build
+pnpm link --global
+
+# Now use it like a normal CLI
+mem0 --help
+mem0 version
+```
+
+> **Warning:** If you also have the Python CLI installed, both register the `mem0` command. The last one linked/installed wins. Unlink with `pnpm unlink --global`.
+
+## Build
+
+```bash
+pnpm build
+```
+
+The compiled output is in `dist/`.
+
+## Run tests
+
+```bash
+# Run all tests
+pnpm test
+
+# Watch mode
+pnpm test:watch
+```
+
+## Lint
+
+```bash
+# Check
+pnpm lint
+
+# Auto-fix
+pnpm lint:fix
+```
+
+## Type checking
+
+```bash
+pnpm typecheck
+```

+# mem0 CLI
+
+The official command-line interface for [mem0](https://mem0.ai) — the memory layer for AI agents.
+
+## Installation
+
+### Using pipx (recommended)
+
+```bash
+pipx install mem0-cli
+```
+
+### Using pip
+
+```bash
+pip install mem0-cli
+```
+
+> **Note:** On macOS with Homebrew Python, `pip install` outside a virtual environment will fail with an `externally-managed-environment` error ([PEP 668](https://peps.python.org/pep-0668/)). Use `pipx` instead, or install inside a virtual environment.
+
+## Quick Start
+
+```bash
+# Set up your configuration
+mem0 init
+
+# 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
+mem0 list --user-id alice
+```

+# Development
+
+## Prerequisites
+
+- Python **3.10+**
+- `make` (optional — you can use plain Python commands instead)
+
+All commands below should be run from the `python/` directory:
+
+```bash
+cd python
+```
+
+## Setup
+
+### Using Make (recommended)
+
+All `make` targets automatically create a virtual environment (`.venv/`) and install the required dependencies — no manual setup needed.
+
+```bash
+# Install the CLI in editable mode
+make install
+
+# Install with dev tools (tests + linting)
+make dev
+```
+
+### Using Python directly
+
+```bash
+python3 -m venv .venv
+source .venv/bin/activate
+python -m pip install -U pip
+
+# Install in editable mode
+pip install -e .
+
+# With dev tools
+pip install -e ".[dev]"
+```
+
+## Make targets
+
+| Target              | Description                                      |
+| ------------------- | ------------------------------------------------ |
+| `make install`      | Create venv and install the CLI (editable mode)  |
+| `make dev`          | Create venv and install CLI + dev dependencies   |
+| `make test`         | Run all tests (installs dev deps if needed)      |
+| `make lint`         | Run linter and format check                      |
+| `make format`       | Auto-fix lint issues and format code             |
+| `make build`        | Build distribution packages                      |
+| `make clean`        | Remove `dist/`                                   |
+| `make publish`      | Build and publish to PyPI                        |
+| `make publish-test` | Build and publish to Test PyPI                   |
+| `make shell`        | Open a new shell with the venv activated         |
+
+## Run tests
+
+```bash
+# Using Make
+make test
+
+# Using Python directly
+pytest
+
+# Run a specific test file
+pytest tests/test_cli_integration.py
+
+# Run a single test
+pytest -k test_help
+```
+
+## Run the CLI
+
+```bash
+# Using Make — drop into an activated shell
+make shell
+mem0 --help
+
+# Using Python directly (with venv activated)
+source .venv/bin/activate
+mem0 --help
+mem0 version
+
+# Or run without activating
+.venv/bin/mem0 --help
+```
+
+## Lint
+
+```bash
+# Using Make
+make lint      # check only
+make format    # auto-fix
+
+# Using Python directly (with venv activated)
+ruff check .
+ruff format .
+```
+
+## Optional extras
+
+### OSS integration
+
+```bash
+pip install -e ".[oss]"
+```

-2. **Use Examples**: Include examples in your prompt for better model understanding
-3. **Structure Output**: Specify the exact JSON format you want returned
+2. **Use 0.0-1.0 Scale**: The score extractor expects values between 0.0 and 1.0
+3. **Request Only the Score**: Ask for just the numerical score to improve extraction reliability
 4. **Test Iteratively**: Refine your prompt based on actual ranking performance
 5. **Consider Token Limits**: Keep prompts concise while being comprehensive

+<Note>
+**Categories vs Metadata:** The Platform version uses `categories=["email"]` which are AI-assigned by Mem0. In open source, categories are modeled as `metadata` fields (e.g., `memory_category`) that you set on each `add` call and filter on during search.

+### Fetching Memories
+
+You can fetch all the memories at any point in time using the following code:
+
+<Tabs>
+  <Tab title="Platform">
+```python
+meeting_emails = processor.search_emails("meeting schedule", user_id)
+for m in meeting_emails['results']:

+
+The mem0 CLI lets you add, search, list, update, and delete memories directly from the terminal. It works with the Mem0 Platform API and is available as both an npm package and a Python package.
+
+Both implementations provide identical behavior — same commands, same options, same output formats.
+
+## Installation
+
+<CodeGroup>
+```bash npm
+npm install -g @mem0/cli
+```
+
+```bash pip
+pip install mem0-cli
+```
+</CodeGroup>
+
+## Authentication
+
+Run the interactive setup wizard to configure your API key:
+
+```bash
+mem0 init
+```
+
+This prompts for your API key and a default user ID, validates the connection, and saves the configuration locally.
+
+For CI/CD or non-interactive environments, pass both values as flags:
+
+```bash
+mem0 init --api-key m0-xxx --user-id alice
+```
+
+You can also set your API key via environment variable:
+
+```bash
+export MEM0_API_KEY="m0-xxx"
+```
+
+## Quick start
+
+```bash
+# 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
+
+# Get a specific memory
+mem0 get <memory-id>
+
+# Update a memory
+mem0 update <memory-id> "I prefer light mode now"
+
+# Delete a memory
+mem0 delete <memory-id>
+```
+
+## Commands

+Retrieve a specific memory by ID.
+
+```bash
+mem0 get 7b3c1a2e-4d5f-6789-abcd-ef0123456789
+mem0 get 7b3c1a2e-4d5f-6789-abcd-ef0123456789 --output json
+```
+
+### `mem0 update`
+
+Update the text or metadata of an existing memory.
+
+```bash
+mem0 update <memory-id> "Updated preference text"
+mem0 update <memory-id> --metadata '{"priority": "high"}'
+echo "new text" | mem0 update <memory-id>
+```
+
+### `mem0 delete`
+
+Delete a single memory, all memories for a scope, or an entire entity.
+
+```bash
+# Delete a single memory
+mem0 delete <memory-id>
+
+# Delete all memories for a user
+mem0 delete --all --user-id alice --force
+
+# Delete all memories project-wide
+mem0 delete --all --project --force
+
+# Preview what would be deleted
+mem0 delete --all --user-id alice --dry-run
+```
+
+| Flag | Description |
+|------|-------------|
+| `--all` | Delete all memories matching scope filters |
+| `--entity` | Delete the entity and all its memories |
+| `--project` | With `--all`: delete all memories project-wide |
+| `--dry-run` | Preview without deleting |
+| `--force` | Skip confirmation prompt |
+
+### `mem0 import`
+
+Bulk import memories from a JSON file.
+
+```bash
+mem0 import data.json --user-id alice
+```
+
+The file should be a JSON array where each item has a `memory` (or `text` or `content`) field and optional `user_id`, `agent_id`, and `metadata` fields.
+
+### `mem0 config`
+
+View or modify the local CLI configuration.
+
+```bash
+mem0 config show              # Display current config (secrets redacted)
+mem0 config get api_key       # Get a specific value
+mem0 config set user_id bob   # Set a value
+```
+
+### `mem0 entities`
+
+List or delete entities (users, agents, apps).
+
+```bash
+mem0 entities list
+mem0 entities list --type agent --output json
+mem0 entities delete --user-id alice --force
+```
+
+### `mem0 status`
+
+Verify your API connection and display the current project.
+
+```bash
+mem0 status
+```
+
+### `mem0 version`
+
+Print the CLI version.
+
+```bash
+mem0 version
+```
+
+## Output formats
+
+All commands support the `--output` flag to control how results are displayed:
+
+| Format | Description |
+|--------|-------------|
+| `text` | Human-readable output with colors and formatting (default for most commands) |
+| `json` | Structured JSON, suitable for piping to `jq` or consumption by AI agents |
+| `table` | Tabular format (default for `list`) |
+| `quiet` | Minimal output — just IDs or status codes |
+
+Example with JSON output:
+
+```bash
+mem0 search "user preferences" --user-id alice --output json | jq '.data.results[].memory'
+```
+
+## Use with AI agents
+
+The CLI is designed to be used by AI agents and automation tools. Two features make this straightforward:
+
+- **`--output json`** returns structured data that agents can parse directly
+- **`mem0 help --json`** returns the full command tree as JSON, so agents can discover available commands programmatically
+
+```bash
+# Agent adds a memory
+mem0 add "User prefers concise responses" --user-id user-42 --output quiet
+
+# Agent searches memories and parses results
+mem0 search "response preferences" --user-id user-42 --output json
+```
+
+For non-interactive environments (CI, agent runtimes), use `mem0 init --api-key --user-id` or set the `MEM0_API_KEY` environment variable to skip interactive prompts.
+
+## Environment variables
+
+| Variable | Description |
+|----------|-------------|
+| `MEM0_API_KEY` | API key (overrides config file) |
+| `MEM0_BASE_URL` | API base URL |
+| `MEM0_USER_ID` | Default user ID |
+| `MEM0_AGENT_ID` | Default agent ID |
+| `MEM0_APP_ID` | Default app ID |
+| `MEM0_RUN_ID` | Default run ID |
+| `MEM0_ENABLE_GRAPH` | Enable graph memory (`true` / `false`) |
+
+Environment variables take precedence over values in the config file, which take precedence over defaults.
+
+## Global flags
+
+These flags are available on all commands that interact with the API:
+
+| Flag | Description |
+|------|-------------|
+| `--api-key` | Override the configured API key for this request |
+| `--base-url` | Override the configured API base URL for this request |
+| `-o, --output` | Set the output format |

+# Mem0 Plugin for Claude Code, Claude Cowork & Cursor
+
+Add persistent memory to your AI workflows. Store, retrieve, and manage memories across sessions using the Mem0 Platform. Works with **Claude Code** (CLI), **Claude Cowork** (desktop app), and **Cursor**.
+
+## Step 1: Set your API key
+
+> **You must complete this step before installing the plugin.**
+
+1. Sign up at [app.mem0.ai](https://app.mem0.ai) if you haven't already
+2. Go to [app.mem0.ai/dashboard/api-keys](https://app.mem0.ai/dashboard/api-keys)
+3. Click **Create API Key** and copy the key (starts with `m0-`)
+4. Add it to your shell profile:
+
+   ```bash
+   # For zsh (default on macOS)
+   echo 'export MEM0_API_KEY="m0-your-api-key"' >> ~/.zshrc
+   source ~/.zshrc
+
+   # For bash
+   echo 'export MEM0_API_KEY="m0-your-api-key"' >> ~/.bashrc
+   source ~/.bashrc
+   ```
+
+5. Confirm it's set:
+
+   ```bash
+   echo $MEM0_API_KEY
+   # Should print: m0-your-api-key
+   ```
+
+## Step 2: Install the plugin
+
+Choose one of the options below. All require `MEM0_API_KEY` to be set first (see above).
+
+### Claude Code (CLI) / Claude Cowork (Desktop)
+
+Claude Code and Claude Cowork share the same plugin system.
+
+**CLI:**
+
+```
+/plugin marketplace add mem0ai/mem0
+/plugin install mem0@mem0-plugins
+```
+
+**Cowork desktop app:** Open the Cowork tab, click **Customize** in the sidebar, click **Browse plugins**, and install Mem0.
+
+This installs the full plugin including the MCP server, lifecycle hooks (automatic memory capture), and the Mem0 SDK skill.
+
+### Cursor
+
+> **Already have `mem0` configured as an MCP server?** Remove the existing entry from your Cursor MCP settings before installing to avoid duplicate tools.
+
+**Option A — One-click deeplink** (installs MCP server only):
+
+[Install Mem0 MCP in Cursor](cursor://anysphere.cursor-deeplink/mcp/install?name=mem0&config=eyJtY3BTZXJ2ZXJzIjp7Im1lbTAiOnsidXJsIjoiaHR0cHM6Ly9tY3AubWVtMC5haS9tY3AvIiwiaGVhZGVycyI6eyJBdXRob3JpemF0aW9uIjoiVG9rZW4gJHtlbnY6TUVNMF9BUElfS0VZfSJ9fX19)
+
+**Option B — Manual configuration** (MCP server only):
+
+Add the following to your `.cursor/mcp.json`:
+
+```json
+{
+  "mcpServers": {
+    "mem0": {
+      "url": "https://mcp.mem0.ai/mcp/",
+      "headers": {
+        "Authorization": "Token ${env:MEM0_API_KEY}"
+      }
+    }
+  }
+}
+```
+
+**Option C — Cursor Marketplace** (full plugin with hooks and skills):
+
+Install from the [Cursor Marketplace](https://cursor.com/marketplace) for the complete experience including lifecycle hooks and the Mem0 SDK skill.
+
+## Verify it works
+
+After installing, confirm the MCP server is connected:
+
+1. Start a new session (or restart your current one)
+2. Ask: *"List my mem0 entities"* or *"Search my memories for hello"*
+3. If the `mem0` tools appear and respond, you're all set
+
+## What's included
+
+| Component | Claude Code / Cowork | Cursor (Marketplace) | Cursor (Deeplink/Manual) |
+|-----------|:--------------------:|:--------------------:|:------------------------:|
+| MCP Server | Yes | Yes | Yes |
+| Lifecycle Hooks | Yes | Yes | No |
+| Mem0 SDK Skill | Yes | Yes | No |
+
+- **MCP Server** — Connects to the Mem0 remote MCP server (`mcp.mem0.ai`), providing tools to add, search, update, and delete memories. No local dependencies required.
+- **Lifecycle Hooks** — Automatic memory capture at key points: session start, context compaction, task completion, and session end.
+- **Mem0 SDK Skill** — Guides the AI on how to integrate the Mem0 SDK (Python & TypeScript) into your applications.
+
+## MCP Tools
+
+Once installed, the following tools are available:
+
+| Tool | Description |
+|------|-------------|
+| `add_memory` | Save text or conversation history for a user/agent |
+| `search_memories` | Semantic search across memories with filters |
+| `get_memories` | List memories with filters and pagination |
+| `get_memory` | Retrieve a specific memory by ID |
+| `update_memory` | Overwrite a memory's text by ID |
+| `delete_memory` | Delete a single memory by ID |
+| `delete_all_memories` | Bulk delete all memories in scope |
+| `delete_entities` | Delete a user/agent/app/run entity and its memories |
+| `list_entities` | List users/agents/apps/runs stored in Mem0 |
