Manage apps with your agent
Your coding agent can manage the full app lifecycle through Kyno’s MCP tools.
HTTP apps sleep automatically after their plan’s inactivity window and wake on the next authenticated visit. Read App sleep and wake for what counts as activity and how this differs from manually stopping an app.
Useful requests
Section titled “Useful requests”List my Kyno apps and show their current status.
Show the recent deployment events for the app named sales-review.
Set
APP_MODE=productionon sales-review and restart it.
Rotate the
OPENAI_API_KEYsecret on sales-review and restart it.
Stop sales-review.
Start sales-review.
Variables and secrets
Section titled “Variables and secrets”get_environment returns variables and secret names. It never returns secret values.
set_variables replaces the app’s non-secret variables. set_secrets adds or replaces encrypted secret values. Restart the app after either change.
Secrets are write-only. If a value is lost, set it again; Kyno cannot show it back through MCP.
Stop, start, and destroy
Section titled “Stop, start, and destroy”Stopping an app removes its active URL but keeps the app record, image, environment, workspace access, and data so it can start again.
A manual stop does not wake automatically when someone visits the app. If you want the app to remain available on demand, let Kyno’s automatic sleep policy manage it instead.
Destroying an app stops it, removes its application image and build cache, deletes its control-plane record, and retires its data disk. The host expires retired data after 30 days, but Kyno does not expose a self-service restore operation.
