gws doesn't ship a static list of commands. It reads Google's own Discovery Service at runtime and builds its entire command surface dynamically. When Google Workspace adds an API endpoint or method, gws picks it up automatically.
Important
This project is under active development. Expect breaking changes as we march toward v1.0.
npm install (or download a pre-built binary from GitHub Releases)gcloud CLI or with the gws auth setup command.The recommended way to install gws is to download the pre-built binary for your OS and architecture from the GitHub Releases page. Extract the archive and place the gws binary in your $PATH.
For convenience, you can also use npm to automate downloading the appropriate binary from GitHub Releases:
npm install -g @googleworkspace/cli
Or build from source:
cargo install --git https://github.com/googleworkspace/cli --locked
A Nix flake is also available at github:googleworkspace/cli
nix run github:googleworkspace/cli
On macOS and Linux, you can also install via Homebrew:
brew install googleworkspace-cli
gws auth setup # walks you through Google Cloud project config gws auth login # subsequent OAuth login gws drive files list --params '{"pageSize": 5}'
For humans — stop writing curl calls against REST docs. gws gives you --help on every resource, --dry-run to preview requests, and auto‑pagination.
For AI agents — every response is structured JSON. Pair it with the included agent skills and your LLM can manage Workspace without custom tooling.
# List the 10 most recent files gws drive files list --params '{"pageSize": 10}' # Create a spreadsheet gws sheets spreadsheets create --json '{"properties": {"title": "Q1 Budget"}}' # Send a Chat message gws chat spaces messages create \ --params '{"parent": "spaces/xyz"}' \ --json '{"text": "Deploy complete."}' \ --dry-run # Introspect any method's request/response schema gws schema drive.files.list # Stream paginated results as NDJSON gws drive files list --params '{"pageSize": 100}' --page-all | jq -r '.files[].name'
The CLI supports multiple auth workflows so it works on your laptop, in CI, and on a server.
| I have… | Use |
|---|---|
gcloud installed and authenticated |
gws auth setup (fastest) |
A GCP project but no gcloud |
Manual OAuth setup |
| An existing OAuth access token | GOOGLE_WORKSPACE_CLI_TOKEN |
| Existing Credentials | GOOGLE_WORKSPACE_CLI_CREDENTIALS_FILE |
Credentials are encrypted at rest (AES-256-GCM) with the key stored in your OS keyring (or ~/.config/gws/.encryption_key when GOOGLE_WORKSPACE_CLI_KEYRING_BACKEND=file).
gws auth setup # one-time: creates a Cloud project, enables APIs, logs you in gws auth login # subsequent scope selection and login
gws auth setuprequires thegcloudCLI. If you don't havegcloud, use the manual setup below instead.
Warning
Scope limits in testing mode: If your OAuth app is unverified (testing mode),
Google limits consent to ~25 scopes. The recommended scope preset includes 85+
scopes and will fail for unverified apps (especially for @gmail.com accounts).
Choose individual services instead to filter the scope picker:
gws auth login -s drive,gmail,sheets
Use this when gws auth setup cannot automate project/client creation, or when you want explicit control.
https://console.cloud.google.com/apis/credentials/consent?project=<PROJECT_ID>https://console.cloud.google.com/apis/credentials?project=<PROJECT_ID>~/.config/gws/client_secret.jsonImportant
You must add yourself as a test user. In the OAuth consent screen, click Test users → Add users and enter your Google account email. Without this, login will fail with a generic "Access blocked" error.
Then run:
gws auth login
You can complete OAuth either manually or with browser automation.
gws auth login, open the printed URL, approve scopes.If consent shows "Google hasn't verified this app" (testing mode), click Continue. If scope checkboxes appear, select required scopes (or Select all) before continuing.
gws auth export --unmasked > credentials.json
export GOOGLE_WORKSPACE_CLI_CREDENTIALS_FILE=/path/to/credentials.json gws drive files list # just works
Point to your key file; no login needed.
export GOOGLE_WORKSPACE_CLI_CREDENTIALS_FILE=/path/to/service-account.json
gws drive files listUseful when another tool (e.g. gcloud) already mints tokens for your environment.
export GOOGLE_WORKSPACE_CLI_TOKEN=$(gcloud auth print-access-token)
| Priority | Source | Set via |
|---|---|---|
| 1 | Access token | GOOGLE_WORKSPACE_CLI_TOKEN |
| 2 | Credentials file | GOOGLE_WORKSPACE_CLI_CREDENTIALS_FILE |
| 3 | Encrypted credentials | gws auth login |
| 4 | Plaintext credentials | ~/.config/gws/credentials.json |
Environment variables can also live in a .env file.
The repo ships 100+ Agent Skills (SKILL.md files) — one for every supported API, plus higher-level helpers for common workflows and 50 curated recipes for Gmail, Drive, Docs, Calendar, and Sheets. See the full Skills Index for the complete list.
# Install all skills at once npx skills add https://github.com/googleworkspace/cli # Or pick only what you need npx skills add https://github.com/googleworkspace/cli/tree/main/skills/gws-drive npx skills add https://github.com/googleworkspace/cli/tree/main/skills/gws-gmail
# Symlink all skills (stays in sync with repo) ln -s $(pwd)/skills/gws-* ~/.openclaw/skills/ # Or copy specific skills cp -r skills/gws-drive skills/gws-gmail ~/.openclaw/skills/
The gws-shared skill includes an install block so OpenClaw auto-installs the CLI via npm if gws isn't on PATH.
Authenticate the CLI first:
gws auth setup
Install the extension into the Gemini CLI:
gemini extensions install https://github.com/googleworkspace/cli
Installing this extension gives your Gemini CLI agent direct access to all gws commands and Google Workspace agent skills. Because gws handles its own authentication securely, you simply need to authenticate your terminal once prior to using the agent, and the extension will automatically inherit your credentials.
gws drive files create --json '{"name": "report.pdf"}' --upload ./report.pdf| Flag | Description | Default |
|---|---|---|
--page-all |
Auto-paginate, one JSON line per page (NDJSON) | off |
--page-limit <N> |
Max pages to fetch | 10 |
--page-delay <MS> |
Delay between pages | 100 ms |
Sheets ranges use ! which bash interprets as history expansion. Always wrap values in single quotes:
# Read cells A1:C10 from "Sheet1" gws sheets spreadsheets values get \ --params '{"spreadsheetId": "SPREADSHEET_ID", "range": "Sheet1!A1:C10"}' # Append rows gws sheets spreadsheets values append \ --params '{"spreadsheetId": "ID", "range": "Sheet1!A1", "valueInputOption": "USER_ENTERED"}' \ --json '{"values": [["Name", "Score"], ["Alice", 95]]}'
Some services ship hand-crafted helper commands alongside the auto-generated Discovery surface. Helper commands are prefixed with + so they are visually distinct and never collide with Discovery-generated method names.
Time-aware helpers (+agenda, +standup-report, +weekly-digest, +meeting-prep) automatically use your Google account timezone (fetched from Calendar Settings API and cached for 24 hours). Override with --timezone/--tz on +agenda, or set the --timezone flag for explicit control.
Run gws <service> --help to see both Discovery methods and helper commands together.
gws gmail --help # shows +send, +reply, +reply-all, +forward, +triage, +watch … gws calendar --help # shows +insert, +agenda … gws drive --help # shows +upload …

gws uses structured exit codes so scripts can branch on the failure type without parsing error output.
| Code | Meaning | Example cause |
|---|---|---|
0 |
Success | Command completed normally |
1 |
API error | Google returned a 4xx/5xx response |
2 |
Auth error | Credentials missing, expired, or invalid |
3 |
Validation error | Bad arguments, unknown service, invalid flag |
4 |
Discovery error | Could not fetch the API schema document |
5 |
Internal error | Unexpected failure |
gws drive files list --params '{"fileId": "bad"}' echo $? # 1 — API error gws unknown-service files list echo $? # 3 — validation error (unknown service)
gws uses a two-phase parsing strategy:
argv[1] to identify the service (e.g. drive)clap::Command tree from the document's resources and methodsAll output — success, errors, download metadata — is structured JSON.
Your OAuth app is in testing mode and your account is not listed as a test user.
Fix: Open the OAuth consent screen in your GCP project → Test users → Add users → enter your Google account email. Then retry gws auth login.
Expected when your app is in testing mode. Click Advanced → Go to <app name> (unsafe) to proceed. This is safe for personal use; verification is only required to publish the app to other users.
Unverified (testing mode) apps are limited to ~25 OAuth scopes. The recommended scope preset includes many scopes and will exceed this limit.
Fix: Select only the scopes you need:
gws auth login --scopes drive,gmail,calendar
gws auth setup requires the gcloud CLI to automate project creation. You have three options:
gcloud directly.gws auth setup which wraps gcloud calls.gcloud entirely — set up OAuth credentials manually in the Cloud ConsoleThe OAuth client was not created as a Desktop app type. In the Credentials page, delete the existing client, create a new one with type Desktop app, and download the new JSON.
If a required Google API is not enabled for your GCP project, you will see a
403 error with reason accessNotConfigured:
{
"error": {
"code": 403,
"message": "Gmail API has not been used in project 549352339482 ...",
"reason": "accessNotConfigured",
"enable_url": "https://console.developers.google.com/apis/api/gmail.googleapis.com/overview?project=549352339482"
}
}gws also prints an actionable hint to stderr:
💡 API not enabled for your GCP project.
Enable it at: https://console.developers.google.com/apis/api/gmail.googleapis.com/overview?project=549352339482
After enabling, wait a few seconds and retry your command.
Steps to fix:

You can also run gws auth setup which walks you through enabling all required
APIs for your project automatically.
