How to Use the Heroku (PaaS) MCP in Cline

Q: Can Cline autonomously restart my Heroku (PaaS) dynos?

Yes. Cline uses listdynos to check container states and can run restartalldynos or restartspecificdyno to resolve memory leaks or hung workers.

Q: Is it safe to let Cline access Heroku (PaaS) config variables?

The listconfigvars tool retrieves sensitive keys like database credentials. Cline uses this data strictly within your local editor context to diagnose connection issues, preventing secret leakage to public files.

Q: What happens if Cline tries to delete an app?

The deleteapp tool will instantly remove the app and route traffic to a 404 page. It is highly recommended to keep Cline's approval prompt active for destructive actions to avoid accidental deletions.

Give Cline the power to manage your Heroku PaaS apps, audit config variables, and restart dynos using this MCP Server.

Complete App Lifecycles inside Cline

The `create_app` and `delete_app` tools let Cline handle the entire lifecycle of your Heroku applications. You can instruct the agent to set up a clean testing environment, run your test suite, and then tear the app down once the build passes. Because Cline writes code and runs tasks autonomously, it can verify that the newly created application is fully functional. It pulls the web URL and git repository targets using `list_apps` to verify deployment routing without manual steps.

Real-time Dyno Diagnostics and Reboots

The `list_dynos` tool provides Cline with immediate telemetry on your running containers, including whether processes have crashed or idled. If a background worker hangs, Cline can execute `restart_specific_dyno` to reboot the single broken process without dropping web traffic. For larger issues, Cline uses `restart_all_dynos` to clear memory leaks across the entire web dyno fleet. This MCP Server lets your agent monitor live infrastructure health directly alongside your codebase.

Safe Database Migrations and Maintenance

The `toggle_maintenance_mode` tool allows Cline to safely isolate your application before running complex database updates. It switches the app to maintenance mode, preventing users from corrupting data during structural migrations. While maintenance is active, Cline checks system constraints using `get_app_info` and updates environment variables via `list_config_vars`. Once the migration scripts finish running, the agent toggles maintenance off to restore public access.
