This mode is different from the headless mode, which is non-interactive and better for scripting.

​
Getting Started

​
Running with Python

Note - OpenHands requires Python version 3.12 or higher (Python 3.14 is not currently supported) and uv for the default fetch MCP server (more details below).

​
Recommended: Using uv

We recommend using uv for the best OpenHands experience. uv provides better isolation from your current project’s virtual environment and is required for OpenHands’ default MCP servers.
  1. Install uv (if you haven’t already): See the uv installation guide for the latest installation instructions for your platform.
  2. Launch OpenHands CLI: 
uvx --python 3.12 --from openhands-ai openhands
If you have cloned the repository, you can also run the CLI directly using Poetry:poetry run openhands
  1. Set your model, API key, and other preferences using the UI (or alternatively environment variables, below).
This command opens an interactive prompt where you can type tasks or commands and get responses from OpenHands. The first time you run the CLI, it will take you through configuring the required LLM settings. These will be saved for future sessions. The conversation history will be saved in ~/.openhands/sessions.

​
Running with Docker

  1. Set the following environment variables in your terminal:
    • SANDBOX_VOLUMES to specify the directory you want OpenHands to access (See using SANDBOX_VOLUMES for more info)
    • LLM_MODEL - the LLM model to use (e.g. export LLM_MODEL="anthropic/claude-sonnet-4-20250514")
    • LLM_API_KEY - your API key (e.g. export LLM_API_KEY="sk_test_12345")
  2. Run the following command: 
docker run -it \
    --pull=always \
    -e SANDBOX_RUNTIME_CONTAINER_IMAGE=docker.all-hands.dev/all-hands-ai/runtime:0.55-nikolaik \
    -e SANDBOX_USER_ID=$(id -u) \
    -e SANDBOX_VOLUMES=$SANDBOX_VOLUMES \
    -e LLM_API_KEY=$LLM_API_KEY \
    -e LLM_MODEL=$LLM_MODEL \
    -v /var/run/docker.sock:/var/run/docker.sock \
    -v ~/.openhands:/.openhands \
    --add-host host.docker.internal:host-gateway \
    --name openhands-app-$(date +%Y%m%d%H%M%S) \
    docker.all-hands.dev/all-hands-ai/openhands:0.55 \
    python -m openhands.cli.entry --override-cli-mode true
If you used OpenHands before version 0.44, you may want to run mv ~/.openhands-state ~/.openhands to migrate your conversation history to the new location.
This launches the CLI in Docker, allowing you to interact with OpenHands. The -e SANDBOX_USER_ID=$(id -u) is passed to the Docker command to ensure the sandbox user matches the host user’s permissions. This prevents the agent from creating root-owned files in the mounted workspace. The conversation history will be saved in ~/.openhands/sessions.

​
Interactive CLI Overview

​
What is CLI Mode?

CLI mode enables real-time interaction with OpenHands agents. You can type natural language tasks, use interactive commands, and receive instant feedback—all inside your terminal.

​
Starting a Conversation

When you start the CLI, you’ll see a welcome message and a prompt (>). Enter your first task or type a command to begin your conversation.

​
Available Commands

You can use the following commands whenever the prompt (>) is displayed:
CommandDescription
/helpShow all available interactive commands and their descriptions
/exitExit the application
/initInitialize a new repository for agent exploration
/statusShow conversation details and usage metrics
/newStart a new conversation
/settingsView and modify current LLM/agent settings
/resumeResume the agent if paused
/mcpManage MCP server configuration and view connection errors

​
Settings and Configuration

You can update your model, API key, agent, and other preferences interactively using the /settings command. Just follow the prompts:
  • Basic settings: Choose a model/provider and enter your API key.
  • Advanced settings: Set custom endpoints, enable or disable confirmation mode, and configure memory condensation.
Settings can also be managed via the config.toml file in the current directory or ~/.openhands/config.toml.

​
Repository Initialization

The /init command helps the agent understand your project by creating a .openhands/microagents/repo.md file with project details and structure. Use this when onboarding the agent to a new codebase.

​
Agent Pause/Resume Feature

You can pause the agent while it is running by pressing Ctrl-P. To continue the conversation after pausing, simply type /resume at the prompt.

​
MCP Server Management

To configure Model Context Protocol (MCP) servers, you can refer to the documentation on MCP servers and use the /mcp command in the CLI. This command provides an interactive interface for managing Model Context Protocol (MCP) servers:
  • List configured servers: View all currently configured MCP servers (SSE, Stdio, and SHTTP)
  • Add new server: Interactively add a new MCP server with guided prompts
  • Remove server: Remove an existing MCP server from your configuration
  • View errors: Display any connection errors that occurred during MCP server startup
This command modifies your ~/.openhands/config.toml file and will prompt you to restart OpenHands for changes to take effect. By default, the Fetch MCP server will be automatically configured for OpenHands. You can also enable search engine via the Tavily MCP server by setting the search_api_key under the [core] section in the ~/.openhands/config.toml file.
Example of the config.toml file with MCP server configuration:
[core]
search_api_key = "tvly-your-api-key-here"

[mcp]
stdio_servers = [
    {name="fetch", command="uvx", args=["mcp-server-fetch"]},
]

sse_servers = [
    # Basic SSE server with just a URL
    "http://example.com:8080/sse",
]

shttp_servers = [
    # Streamable HTTP server with API key authentication
    {url="https://secure-example.com/mcp", api_key="your-api-key"}
]

​
Tips and Troubleshooting

  • Use /help at any time to see the list of available commands.
  • If you encounter permission issues, make sure your workspace directory is trusted and all required environment variables are set correctly.
  • For advanced LLM configuration, use the advanced options in /settings.
  • When confirmation mode is enabled, the CLI will prompt before sensitive operations. You can type a or always at the first confirmation prompt to automatically confirm subsequent actions for the current conversation.
  • If you want to start over, use /new to begin a fresh conversation without restarting the CLI.
