hapi CLI

Run Claude Code, Codex, or Gemini sessions from your terminal and control them remotely through the hapi server.

What it does

• Starts Claude Code sessions and registers them with hapi-server.
• Starts Codex mode for OpenAI-based sessions.
• Starts Gemini mode via ACP (Anthropic Code Plugins).
• Provides an MCP stdio bridge for external tools.
• Manages a background daemon for long-running sessions.
• Includes diagnostics and auth helpers.

Typical flow

1. Start the server and set env vars (see ../server/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 gemini - Start Gemini mode via ACP. See src/agent/runners/runAgentSession.ts. Note: Gemini runs in remote mode only; it waits for messages from the server UI/Telegram.

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.

Daemon management

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

See src/daemon/run.ts.

Diagnostics

• hapi doctor - Show full diagnostics (version, daemon 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 server - Start the bundled server (single binary workflow).

Configuration

See src/configuration.ts for all options.

Required

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

Optional

• HAPI_HOME - Config/data directory (default: ~/.hapi).
• HAPI_EXPERIMENTAL - Enable experimental features (true/1/yes).
• HAPI_CLAUDE_PATH - Path to a specific claude executable.
• HAPI_HTTP_MCP_URL - Default MCP target for hapi mcp.

Daemon

• HAPI_DAEMON_HEARTBEAT_INTERVAL - Heartbeat interval in ms (default: 60000).
• HAPI_DAEMON_HTTP_TIMEOUT - HTTP timeout for daemon control in ms (default: 10000).

Storage

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

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

Requirements

• Claude CLI installed and logged in (claude 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

Source structure

• src/codex/ - Codex mode integration.
• src/agent/ - Multi-agent support (Gemini via ACP).
• src/daemon/ - Background service.
• src/commands/ - CLI command handlers.
• src/ui/ - User interface and diagnostics.
• src/modules/ - Tool implementations (ripgrep, difftastic, git).
