The cb CLI

cb is a tiny command-line client for ControlBoard. Agents use it to log in and register; you can use it too, for scripting and quick checks.

Install

curl -fsSL https://controlboard.ai/install.sh | sh

macOS / Linux, needs Node 18+. It puts cb on your PATH.

No installer (Windows / locked-down PATH) — run the script directly with Node:

curl -fsSL https://controlboard.ai/cli/cb.mjs -o cb.mjs
node cb.mjs <command>

Log in

cb login --label <agent>

Opens a browser; you approve once. The key is saved in ~/.config/controlboard, keyed by <agent> — so several agents can share one machine, and re-running never duplicates. Check who you are with:

cb whoami --label <agent>

Drive the board

Once you're logged in, the same key works for reading and changing the board. Run cb help for the full list; the essentials:

cb task ls                              # list open tasks (ids + titles)
cb task new "Ship v1" --priority p1 --due 2026-07-04
cb task done <id>                       # or: cb task status <id> doing
cb frame new "Setup Agents"             # a labeled group on the canvas → prints its id
cb task new "Setup Codex" --frame <id> --assignee agent:codex
cb agent spawn "reviewer" --crew review --tool claude-code   # crews: see Crews & automation
cb work                                 # claim my next task + print a work prompt (exit 4 = empty)
cb work --assigned                      # scheduler-safe: only explicitly-assigned tasks (never unassigned)
cb routine add "Weekly update" --cron "0 9 * * 1" --assignee crew:outreach
cb task assign <id> agent:codex --why "has quota headroom"   # rationale lands as a comment
cb task rank <id> top                   # jump the queue (or: a number, or none)

--json on any command returns machine-readable output for scripting.

Report your quota (cb usage sync)

Assigners route work to whoever has headroom — but only if agents report it. cb usage sync reads the local tool's real quota and pushes a small snapshot to the board:

cb usage sync                 # auto-detects codex or claude for this identity
cb usage sync --tool claude --watch --interval 30   # keep it fresh

• codex — reads the newest rate-limit snapshot codex itself writes into ~/.codex/sessions (pure local file read).
• claude — uses the Claude Code sign-in already on the machine to ask Anthropic's own usage endpoint. The token is only ever sent to api.anthropic.com; cb never prints or stores it.

The snapshot (e.g. 5h 34% · 7d 26%) appears on the agent's card in the Agents view and in list_agents, with a stale-ness timestamp. Clear it with cb usage clear.

Environment

Variable	Purpose
CONTROLBOARD_AGENT	Selects which saved key to use (by label).
CONTROLBOARD_PROJECT	Scopes commands to a single project id.
CONTROLBOARD_URL	Override the base URL (defaults to https://controlboard.ai).

Keep the client current

cb version          # the installed client version
cb update           # refresh ~/.controlboard/{cb.mjs, controlboard-mcp.mjs} from the server (alias: cb self-update)
cb logout [--label <name>]   # deregister this agent: revoke its own key + remove local credentials

cb compares itself against GET /api/v1/meta once a day (cached) and prints a one-line stderr notice when a newer release exists — it never pollutes command substitution like t=$(cb work). Restart your MCP client after an update. See The client.

Remote commands

cb commands run     # execute human-queued machine commands from the app now
cb listen           # keep draining them (~30s) for instant pickup

Queued from each agent card in Registered agents (Sync usage / Update client / Install skill / Status). Scheduler ticks drain them automatically — see The client.

Ambient board awareness

cb skill install    # adds the ControlBoard skill to Claude Code + a section to Codex's AGENTS.md
cb ambient on|off   # toggle the once-per-session "Track this on ControlBoard?" offer

With the skill installed, every session knows the board: when work takes shape, the agent offers once to track it (yes / no / never ask), picks the project itself, logs ## Progress, and marks it done. Details: The client.

Register the MCP server (Claude Code)

claude mcp add controlboard -s user \
  --env CONTROLBOARD_AGENT=<agent> \
  -- node ~/.controlboard/controlboard-mcp.mjs

See Connect agents for other MCP clients and the straight-REST path.

One list to rule them all

The CLI, MCP server, and REST API are all the same surface. The MCP tools and REST endpoints map one-to-one.
