cua connect setup [OPTIONS]

Flag	Short	Type	Default	Description
`--agents`		string		Agents: `all` (installed), `none`, or ids such as `claude,codex,hermes` (`cua connect detect` lists every supported agent).
`--mcp-command`		string		Command agents launch for the MCP server (default: the `cua` on PATH, else this binary).
`--skills-only`		boolean	`false`	Only install skills. Alias: `--no-mcp`.
`--mcp-only`		boolean	`false`	Only configure the MCP server. Alias: `--no-skills`.
`--yes`	`-y`	boolean	`false`	Answer yes to every prompt.
`--force`		boolean	`false`	Replace skill folders cua did not write (the old one is backed up).
`--cua-driver`		boolean	`false`	Set up background computer-use instead: the cua-driver skill and the cua-driver MCP server (`cua-driver mcp`). --mcp-command then names the cua-driver binary.
`--sign-in`		boolean	`false`	Also make a sign-in for each agent's runs in your Spaces and keep it in Keyvault on This Mac: the sign-in Claude Code already has (read from where Claude Code keeps it, as an access token only; Claude Code's own sign-in is never changed) and Codex's own device sign-in (a link and a code to enter there, in a folder Cua owns); Hermes uses the providers connected in Cua Spaces (Settings, Connections). Only Claude Code's own sign-in is read, and only its access token is kept; Codex's own `auth.json` is never read or changed.
`--sign-in-only`		boolean	`false`	Only the sign-in, as `--sign-in`, and nothing else: no Cua skills and no MCP entry are added to any agent, Claude Code is never run to refresh its own sign-in, and nothing is written outside the Cua home (the access token goes to Keyvault, never printed). For a demo, or a home Space that only needs the credential. On a Mac, macOS asks once to let Cua read the Keychain item "Claude Code-credentials": that prompt is yours to answer.

Examples

# Every installed agent, asking before each change
cua connect setup
 
# Claude Code and Codex, no prompts
cua connect setup --agents claude,codex -y
 
# Hermes Agent (Nous Research): ~/.hermes/skills and ~/.hermes/config.yaml
cua connect setup --agents hermes -y
 
# Only the MCP server entry
cua connect setup --mcp-only
 
# Background computer-use: the cua-driver skill and MCP server
cua connect setup --cua-driver --agents all -y
 
# Also copy each agent's sign-in to Keyvault on This Mac (Codex's ChatGPT sign-in, the sign-in Claude Code already has, Hermes' key)
cua connect setup --agents codex,claude --sign-in -y

`cua connect status`#

Whether each agent is really connected: installed and its version, signed in, Cua's MCP entry present and answering, and its sign-in copied to Keyvault. The same rows as the app and the connect_status MCP tool.

cua connect status [OPTIONS]

Examples

cua connect status
cua connect status --json

`cua connect remove`#

Remove the Cua Spaces skills and MCP entries cua added (nothing else).

cua connect remove [OPTIONS]

Flag	Short	Type	Default	Description
`--agents`		string	`all`	Agents: `all` (default) or ids such as `claude,codex`.
`--skills-only`		boolean	`false`	Only remove skills.
`--mcp-only`		boolean	`false`	Only remove the MCP entry.
`--yes`	`-y`	boolean	`false`	Do not ask for confirmation.
`--include-cua-driver`		boolean	`false`	Also remove Cua Driver's skill and MCP server (`cua-driver`). Without it only Cua Spaces' own entries go: the `cua` server (`cua-local` for Local) and the Cua Spaces skills.
`--dry-run`		boolean	`false`	List exactly what would be removed and change nothing.
`--sign-in`		boolean	`false`	Also delete the sign-ins Connect copied to Keyvault for these agents.

# Cua Driver's skill and MCP server too (they stay otherwise)
cua connect remove --include-cua-driver

`cua connect update`#

Refresh installed cua skills and managed MCP entries to this version.

cua connect update [OPTIONS]

Examples

cua connect update

`cua connections`#

The AI providers connected once for every app that can use them: list, add (a key from stdin), test, remove. What Cua Spaces shows in Settings, Connections. (cua connect connects your coding apps to Cua.).

cua connections [OPTIONS] <COMMAND>

Examples

cua connections list
cua connections add deepseek
cua connections test
cua connections remove deepseek

`cua connections list`#

List the providers with their state (Connected, Needs reconnect, Not connected) and the apps each works with. Never prints a key.

cua connections list [OPTIONS]

Flag	Type	Default	Description
`--all`	boolean	`false`	Also list every provider that is not connected (by default: the ones up front and the ones with something saved).

Examples

cua connections list
cua connections list --all
cua --json connections list

`cua connections add`#

Connect a provider. The key is read from stdin (pipe it in; a terminal is refused so it isn't echoed). Saving never waits on the provider: cua connections test asks it afterwards.

The provider is one of the ids cua connections list --all prints. Pipe the key in: pbpaste | cua connections add deepseek. Sign-ins another app made on this machine are imported with cua connect setup <app> --sign-in.

cua connections add [OPTIONS] <PROVIDER>

Argument	Type	Default	Description
`<PROVIDER>`	string	required	The provider id (`cua connections list --all`).

Flag	Type	Description
`--method`	string	How: `key` (an API key from stdin; the default) or `endpoint` (a custom endpoint: its base URL, model and API style; a key is optional).
`--region`	string	The plan or region, for a provider that has them (Z.AI: global, cn, coding-global, coding-cn).
`--model`	string	The model to use, for a provider with no default model or to choose another.
`--base-url`	string	A custom endpoint's base URL.
`--wire`	string	A custom endpoint's API style: openai-chat (default), openai-responses or anthropic.

Examples

cua connections add deepseek
cua connections add zai --region coding-global
cua connections add deepinfra --model meta-llama/Meta-Llama-3.1-70B-Instruct
cua connections add custom --base-url http://host:1234/v1 --model qwen

`cua connections test`#

Ask each provider whether its saved key still works (a read-only request on the provider's own host, bounded in time; offline is not a failure). A key the provider refuses is listed as Needs reconnect.

cua connections test [OPTIONS] [PROVIDER]

Argument	Type	Default	Description
`<PROVIDER>`	string	optional	Only this provider.

Examples

cua connections test
cua connections test openrouter

`cua connections remove`#

Disconnect a provider: remove what is saved for it.

cua connections remove [OPTIONS] <PROVIDER>

Argument	Type	Default	Description
`<PROVIDER>`	string	required

Examples

cua connections remove deepseek

`cua connections github`#

The GitHub sign-in used for an approved push: what is signed in and a switch per host. An experiment: see cua experiments.

When an agent asks to push a branch and open a pull request, the host does it after you say yes on the card. This shows which account will be used and never prints a token.

Cua tries, in order: a token saved in Settings, Connections; GH_TOKEN or GITHUB_TOKEN in the Cua daemon's environment; the GitHub CLI (gh auth login), read only when an approved push runs; then git's own SSH key or credential helper for a repository with an SSH remote.

cua connections github [OPTIONS] [COMMAND]

cua connections github
cua connections github rescan
cua connections github use bob
