You can also read these from your terminal with `man devin`.

## Subcommands

### devin auth

Authentication related commands.

| Command | Description |
| --- | --- |
| `devin auth login` | Log in to your account |
| `devin auth logout` | Log out and remove stored credentials |
| `devin auth status` | Check authentication status |

**Options for `devin auth login`:**

- `--force-manual-token-flow` — Skip browser-based auth and manually paste a token (useful for remote/SSH sessions)

### devin mcp

Connect and log in to Model Context Protocol servers.

| Command | Description |
| --- | --- |
| `devin mcp add <name>` | Add a new MCP server |
| `devin mcp list` | List all configured MCP servers |
| `devin mcp get <name>` | Show details for a specific MCP server |
| `devin mcp remove <name>` | Remove a configured MCP server |
| `devin mcp login <name>` | Authenticate with an MCP server via OAuth |
| `devin mcp logout <name>` | Remove stored OAuth credentials for an MCP server |

**Options for `devin mcp add`:**

- `-t, --transport <stdio|http>` — Transport type (optional; inferred from URL → http, trailing args → stdio)
- `-s, --scope <local|project|user>` — Configuration scope (default: `local`)
- `--url <URL>` — URL for HTTP transport (can also be passed as a positional argument after the name)
- `--command <CMD>` — Command for stdio transport (optional when trailing args are provided)
- `-e, --env <KEY=VALUE>` — Environment variables (repeatable)
- `-H, --header <HEADER: VALUE>` — HTTP headers (repeatable)
- `--scopes <SCOPE,SCOPE>` — OAuth scopes to request (comma-separated)
- `<URL>` — Positional URL argument for HTTP (alternative to `--url`)
- `-- <COMMAND> [ARGS...]` — Command and arguments for stdio (first arg is the command when `--command` is omitted)

<Note>
  HTTP servers try Streamable HTTP first and fall back to legacy SSE on 4xx errors (per the [MCP spec](https://spec.modelcontextprotocol.io/specification/2025-03-26/basic/transports/#backwards-compatibility)). You can also set `"transport": "sse"` explicitly. See [MCP Configuration → Legacy SSE fallback](/extensibility/mcp/configuration#legacy-sse-fallback).
</Note>

**Examples:**

```bash
# stdio server
devin mcp add my-server -- npx @company/mcp-server --port 3000

# HTTP server (positional URL)
devin mcp add notion https://mcp.notion.com/mcp
devin mcp add --transport http datadog-mcp https://mcp.datadoghq.com/api/unstable/mcp-server/mcp

# HTTP server (--url flag, also works)
devin mcp add notion --url https://mcp.notion.com/mcp

# With environment variables and scope
devin mcp add -e GITHUB_TOKEN=ghp_xxx github -- npx -y @modelcontextprotocol/server-github
devin mcp add -s project sentry https://mcp.sentry.dev/mcp
```

**Options for `devin mcp remove`:**

- `-s, --scope <local|project|user>` — Configuration scope (default: `local`)

### devin list

List sessions in the current directory. Alias: `devin ls`

| Command | Description |

| `devin list` | Interactive session picker (default) |
| `devin list --format json` | Output sessions as JSON |

### devin version

Print the current version and exit.

```bash
devin version
```

This is equivalent to `devin --version`.

### devin acp

Run Devin as an [Agent Client Protocol (ACP)](https://agentclientprotocol.com/) server over stdio. This subcommand is intended to be invoked by an ACP-aware editor or IDE (such as Windsurf or Zed) as a subprocess — it speaks JSON-RPC over stdin/stdout and is not meant to be run interactively.

```bash
devin acp
```

The ACP server reads credentials from `WINDSURF_API_KEY` if set, otherwise from the credentials stored by `devin auth login`. It can also accept credentials at runtime via the ACP `authenticate` request.

### devin update

Check for updates and optionally install them.

```bash
devin update
```

Use `--force` to re-install even if already on the latest version:

```bash
devin update --force
```

### devin shell

[Feature Preview] Shell integration commands. See [Shell Integration](/shell-integration) for full details.

| Command | Description |
| --- | --- |
| `devin shell setup` | Install shell integration into your shell config file |
| `devin shell setup <shell>` | Install for a specific shell (`bash`, `zsh`, or `fish`) |

### devin setup

Interactive setup wizard for authentication and MCP configuration.

```bash
devin setup
devin setup --force-manual-token-flow  # For remote/SSH sessions
```

### devin uninstall

Uninstall Devin CLI and optionally remove all data.

| Option | Description |
| --- | --- |
| `--clean` | Remove all data including configuration, history, and custom data |
| `--force` | Skip confirmation prompt |

---

## Modes

Modes control the agent's autonomy level by combining a permission mode with an agent profile.

<Tabs>
  <Tab title="Normal (default)">
    Full autonomy for complex coding tasks. The agent can read, write, and execute commands with normal permission checks.

    - **Permission mode:** Normal
    - **Profile:** Normal
    - **Use for:** Multi-file refactoring, feature implementation, bug fixes
  </Tab>
  <Tab title="Plan">
    Planning only — the agent proposes changes without making them. Read-only tool access ensures no code is modified.

    - **Permission mode:** Normal
    - **Profile:** Plan (read-only tools)
    - **Use for:** Architecture design, understanding codebases, planning before implementation
  </Tab>
  <Tab title="Bypass">
    All permission prompts are auto-approved. The agent executes freely without asking for confirmation.

    - **Permission mode:** Dangerous
    - **Profile:** Normal
    - **Use for:** Trusted tasks where interruptions slow you down

    <Warning>
      Use Bypass mode only for tasks you fully trust. All tool calls (including destructive commands) are auto-approved.
    </Warning>
  </Tab>
</Tabs>

Cycle between modes with `/mode`, or switch directly with `/normal`, `/accept-edits`, `/plan`, or `/bypass`. Use `/ask <question>` as a oneshot command to ask questions without switching modes.

---

## Profiles

Profiles determine the agent's available tools and behavior. Profiles are automatically set when you switch modes.

| Profile | Description | Tool Access |
| --- | --- | --- |
| `normal` | Full coding assistant (used by Normal, Accept Edits, and Bypass modes) | All tools |
| `plan` | Structured planning workflow (used by Plan mode) | Read-only tools (grep, glob, read, todo, ask\_user\_question, exit\_plan\_mode) |
| `ask` | Question answering (used by the `/ask` command) | Read-only tools (grep, glob, read, todo, ask\_user\_question) |
