hapi/cli

hapi CLI

Run Claude Code, Codex, Cursor Agent, Grok Build, or OpenCode sessions from your terminal and control them remotely through the hapi hub.

What it does

• Starts Claude Code sessions and registers them with hapi-hub.
• Starts Codex mode for OpenAI-based sessions.
• Starts Cursor Agent mode for Cursor CLI sessions.
• Starts Grok Build locally or via ACP for remote sessions.
• Starts OpenCode mode via ACP and its plugin hook system.
• Provides an MCP stdio bridge for external tools.
• Manages a background runner for long-running sessions.
• Includes diagnostics and auth helpers.

Typical flow

1. Start the hub and set env vars (see ../hub/README.md).
2. Set the same CLI_API_TOKEN on this machine or run hapi auth login.
3. Run hapi to start a session.
4. Use the web app or Telegram Mini App to monitor and control.

Commands

Session commands

• hapi - Start a Claude Code session (passes through Claude CLI flags). See src/index.ts.
• hapi codex - Start Codex mode. See src/codex/runCodex.ts.
• hapi codex resume <sessionId> - Resume existing Codex session.
• hapi cursor - Start Cursor Agent mode. See src/cursor/runCursor.ts. Supports hapi cursor resume <chatId>, hapi cursor --continue, --mode plan|ask, --yolo, --model. Local and remote modes supported; remote uses agent -p with stream-json.
• hapi grok - Start Grok Build mode. See src/grok/runGrok.ts.
• hapi opencode - Start OpenCode mode via ACP. See src/opencode/runOpencode.ts. Note: OpenCode supports local and remote modes; local mode streams via OpenCode plugins.
• hapi resume [sessionId] - List resumable sessions for this machine or resume one locally.
• hapi ping-peer <session-id-prefix> <message> - Resume (if needed) and message another session. Prefer this or MCP ping_peer over reinventing JWT+curl. Also --message-file / --list.
• hapi inspect-peer <session-id-or-prefix> - Read-only peer metadata + recent message text (no resume). Prefer this or MCP inspect_peer when a user cites [title](/sessions/<id>). Optional --limit.

Resume a remote session locally

hapi resume
hapi resume <session-id>

hapi resume lists resumable sessions for the current machine. hapi resume <session-id> hands off an active remote session and opens the same HAPI session in the local terminal.

Authentication

• hapi auth status - Show authentication configuration and token source.
• hapi auth login - Interactively enter and save CLI_API_TOKEN.
• hapi auth logout - Clear saved credentials.

See src/commands/auth.ts.

Runner management

• hapi runner start - Start runner as detached process.
• hapi runner stop - Stop runner gracefully.
• hapi runner status - Show runner diagnostics.
• hapi runner list - List active sessions managed by runner.
• hapi runner stop-session <sessionId> - Terminate specific session.
• hapi runner logs - Print path to latest runner log file.

Both start and start-sync accept repeatable --workspace-root <path> (or --workspace-root=<path>). When set:

• The web /browse page surfaces scoped file trees rooted at those paths.
• The runner refuses list-directory and spawn-session requests for paths outside the configured roots.
• ~ and ~/foo are expanded.

Omitting the flag keeps the legacy behavior: no scoping, no /browse feature.

See src/runner/run.ts.

Diagnostics

• hapi doctor - Show full diagnostics (version, runner status, logs, processes).
• hapi doctor clean - Kill runaway HAPI processes.

See src/ui/doctor.ts.

Other

• hapi mcp - Start MCP stdio bridge. See src/codex/happyMcpStdioBridge.ts.
• hapi hub - Start the bundled hub (single binary workflow).
• hapi server - Alias for hapi hub.

Configuration

See src/configuration.ts for all options.

Required

• CLI_API_TOKEN - Shared secret; must match the hub. Can be set via env or ~/.hapi/settings.json (env wins).
• HAPI_API_URL - Hub base URL (default: http://localhost:3006).

Optional

• HAPI_HOME - Config/data directory (default: ~/.hapi).
• HAPI_EXPERIMENTAL - Enable experimental features (true/1/yes).
• HAPI_EXTRA_HEADERS_JSON - JSON object of extra headers to send on CLI → hub requests, e.g. {"Cookie":"CF_Authorization=..."}. Can also be set as the extraHeaders object in ~/.hapi/settings.json (environment variable wins).
• HAPI_CLAUDE_PATH - Path to a specific claude executable.
• HAPI_HTTP_MCP_URL - Default MCP target for hapi mcp.

Runner

• HAPI_RUNNER_HEARTBEAT_INTERVAL - Heartbeat interval in ms (default: 60000).
• HAPI_RUNNER_HTTP_TIMEOUT - HTTP timeout for runner control in ms (default: 10000).

Worktree (set by runner)

• HAPI_WORKTREE_BASE_PATH - Base repository path.
• HAPI_WORKTREE_BRANCH - Current branch name.
• HAPI_WORKTREE_NAME - Worktree name.
• HAPI_WORKTREE_PATH - Full worktree path.
• HAPI_WORKTREE_CREATED_AT - Creation timestamp (ms).

Set for the wrapped agent

• HAPI_SESSION_ID - The hub session id for the current run, exported into the wrapped agent/CLI child environment at spawn for every flavor (claude / codex / copilot / cursor / gemini / opencode / kimi / grok / pi), both runner-spawned and locally started sessions. Agents can read it to self-target "this chat" over the hub REST API or shell helpers without listing /api/sessions. Prefer the MCP display_image tool for inline media when it is available; use HAPI_SESSION_ID for hub REST / shell tooling where MCP is not. To read another session, prefer MCP inspect_peer or hapi inspect-peer. To message another session, prefer MCP ping_peer or hapi ping-peer — do not reinvent JWT+curl. User citations look like [title](/sessions/<id>); pass that <id> as sessionIdPrefix.

  Lazy Codex (terminal) sessions export the id only after the hub row is materialized, which happens when the MCP bridge starts — before the agent process is spawned — so path-only self-targeting does not race a missing hub row.

  Example (shell fallback when MCP is unavailable) — path-only, self-targets the current session:

  bun scripts/tooling/hapi-display-image.mjs /absolute/path/to/image.png "optional title"
  

  Explicit other session (prefix or full uuid) still works; that path may list sessions.

Storage

Data is stored in ~/.hapi/ (or $HAPI_HOME):

• settings.json - User settings (machineId, token, onboarding flag). See src/persistence.ts.
• runner.state.json - Runner state (pid, port, version, heartbeat).
• logs/ - Log files.

Requirements

• Claude CLI installed and logged in (claude on PATH).
• Cursor Agent CLI installed (agent on PATH) for hapi cursor. Install: curl https://cursor.com/install -fsS | bash (macOS/Linux), irm 'https://cursor.com/install?win32=true' | iex (Windows).
• Grok Build CLI installed (grok on PATH) for hapi grok. Authenticate with grok login --device-auth on headless runner machines, or set XAI_API_KEY.
• OpenCode CLI installed (opencode on PATH).
• Bun for building from source.

Build from source

From the repo root:

bun install
bun run build:cli
bun run build:cli:exe

For an all-in-one binary that also embeds the web app:

bun run build:single-exe
