About mcloud-variables

A skill for using `mcloud variables` to inspect and manage environment variables in Cloud environments. It documents safe handling of secrets and the redeploy or build steps needed for changes to take effect.

Key features

  1. 01List variables by type and scope
  2. 02Retrieve variables by key or ID
  3. 03Create and update variables
  4. 04Delete variables with confirmation safeguards
  5. 05Mark variables as secret, build, or runtime

Use cases

  1. 01Review environment configuration
  2. 02Update API keys or other variables
  3. 03Load variables from a .env file
  4. 04Remove an obsolete variable

Install

Copy the command and run it in a terminal.

$npx skills add https://github.com/medusajs/medusa-agent-skills --skill mcloud-variables

After installing, type/mcloud-variablesin Claude Code to confirm it loaded.

Cloud CLI: Variables Commands

Execute mcloud variables commands to inspect and manage environment variables for Cloud environments.

Constraints

  • Never pass --reveal unless the user explicitly asks. Secret values appear in terminal scrollback, log aggregators, and process listings.
  • Variable changes need a deploy to apply. set/delete don't rebuild or redeploy. Run mcloud environments redeploy <env> for a runtime variable, or mcloud environments trigger-build <env> for a build variable (a redeploy reuses the existing image and won't pick up build-variable changes).
  • System variables can't be deleted, and delete requires --yes in non-interactive mode.
  • Looking up or creating a variable by key requires --project and --environment (or the equivalent in active context). Referencing by ID (var_...) works without project/environment context.
  • set and delete require mcloud CLI v0.1.10+.

Commands

variables list

List all environment variables for a Cloud environment.

mcloud variables list \
  --organization <org-id> \
  --project <project-id-or-handle> \
  --environment <environment-handle> \
  --json

Options:

  • -o/--organization <id> — Organization ID (falls back to active context)
  • -p/--project <id-or-handle> — Project ID or handle (falls back to active context)
  • -e/--environment <handle> — Environment handle (falls back to active context)
  • -t/--type <backend|storefront> — Which variable set to list (default: backend)
  • --scope <build|runtime> — Filter by scope; repeatable (default: both scopes)
  • --include-system — Include system variables Medusa auto-injects (default: false)
  • --reveal — Print secret values in plaintext instead of masking (use only when explicitly asked)
  • --dotenv — Output .env-formatted KEY=VALUE lines instead of a table
  • --json — Output as JSON
variables get

Retrieve a single variable by its ID (var_...) or key.

# By key (requires project + environment context)
mcloud variables get ADMIN_CORS \
  --organization <org-id> \
  --project <project-id-or-handle> \
  --environment <environment-handle> \
  --json

# By ID (works without project/environment context)
mcloud variables get var_01XYZ --json

Arguments:

  • variable — Variable ID (var_...) or key (required)

Options:

  • -o/--organization <id>, -p/--project <id-or-handle>, -e/--environment <handle>
  • -t/--type <backend|storefront> — Which variable set to read (default: backend)
  • --reveal — Print secret value in plaintext (use only when explicitly asked)
  • --json — Output as JSON
variables set

Create or update one or more variables. The CLI updates when you reference an existing key or a var_... ID, and creates otherwise.

# Single variable
mcloud variables set API_KEY pk_123 \
  --organization <org-id> \
  --project <project-id-or-handle> \
  --environment <environment-handle>

# Multiple at once
mcloud variables set -v API_KEY=pk_123 -v CLIENT_ID=my_app

# From a .env file
mcloud variables set --env-file .env

Arguments:

  • variable — Variable ID (var_...) or key to set (omit when using --var/--env-file)
  • value — Value to set (required when a variable argument is passed)

Options:

  • -o/--organization <id>, -p/--project <id-or-handle>, -e/--environment <handle>
  • -t/--type <backend|storefront> — Which variable set to write (default: backend)
  • -v/--var <KEY=VALUE|ID=VALUE> — A variable to set; repeatable
  • --env-file <path> — Set all variables from a .env file
  • --secret, --no-secret — Mark as secret (default: false for new variables)
  • --build, --no-build — Available at build time (default: false for new variables)
  • --runtime, --no-runtime — Available at runtime (default: true for new variables)
  • --json — Output as JSON

Redeploy (runtime) or trigger-build (build) afterward — see Constraints.

variables delete

Delete a variable by its ID (var_...) or key. Irreversible; system variables can't be deleted.

mcloud variables delete API_KEY \
  --organization <org-id> \
  --project <project-id-or-handle> \
  --environment <environment-handle> \
  --yes

Arguments:

  • variable — Variable ID (var_...) or key to delete (required)

Options:

  • -o/--organization <id>, -p/--project <id-or-handle>, -e/--environment <handle>
  • -t/--type <backend|storefront> — Which variable set to delete from (default: backend)
  • -y/--yes — Skip confirmation prompt (required in non-interactive mode)
  • --json — Output as JSON

Variable Fields (JSON)

FieldDescription
idVariable ID (var_...)
keyVariable name (e.g. ADMIN_CORS)
valueVariable value (masked if is_secret and --reveal not passed)
is_secretWhether the variable is treated as a secret
is_buildAvailable at build time
is_runtimeAvailable at runtime
environment_idThe environment ID this variable belongs to
sourceuser for user-set variables, system for auto-injected ones

Examples

# List all variables for the active environment
mcloud variables list --json

# List only runtime variables, including system ones
mcloud variables list --scope runtime --include-system --json

# List storefront variables
mcloud variables list --type storefront --json

# Get a variable by key (with active context)
mcloud variables get DATABASE_URL --json

# Get a variable by ID (no env context needed)
mcloud variables get var_01XYZ --json

# Set a single variable, then redeploy to apply (runtime)
mcloud variables set REDIS_URL redis://cache:6379
mcloud environments redeploy production

# Set a secret build-only variable, then trigger a build to apply
mcloud variables set STRIPE_SECRET_KEY sk_live_123 --secret --build --no-runtime
mcloud environments trigger-build production

# Set multiple variables from a .env file
mcloud variables set --env-file .env

# Delete a variable (irreversible — confirm before running)
mcloud variables delete OLD_FLAG --yes

# Only reveal secrets when user explicitly asks
mcloud variables get STRIPE_SECRET_KEY --reveal --json | jq -r '.value'

# Export all variables to a .env file (user must explicitly request --reveal)
mcloud variables list --reveal --dotenv > .env

# Check if a specific variable exists
mcloud variables list --json | jq '.[] | select(.key == "REDIS_URL")'
