Short answer

How can I change my Railway variables using AI?

Your agent uses the Railway MCP to find your services and modify their configuration. You can add new secrets or remove old ones just by asking. This breakdown shows you how to handle service settings through chat.

Configuration outcomes

What you can do

These are the direct results of your commands.

READ

View current settings

The agent pulls your active service list and variable values. You get a clear view of what's currently running.

WRITE

Update your secrets

The agent pushes new key-value pairs to your service. Your deployment updates with the new data immediately.

DELETE

Remove old variables

The agent clears out specific keys you no longer need. This keeps your environment clean and secure.

HUMAN

Manual verification

You decide when a change is critical enough to check in the Railway dashboard. The agent handles the heavy lifting, but you keep the final say.

The workflow

What your AI does when <the thing arrives>.

The agent follows a specific sequence to ensure your service stays stable.

  1. Identify the service

    The agent looks through your Railway account to find the specific project or service you want to change.

    list_services

  2. Check existing values

    Before making changes, the agent reads the current environment variables to avoid overwriting something important.

    list_variables

  3. Apply the change

    The agent sends the new variable or secret to the Railway API to update your configuration.

    set_variable

  4. Clean up

    If you need to remove a deprecated key, the agent executes the deletion command.

    delete_variable

FAQ

How this task behaves

  • 01

    Can my AI deploy new services?

    No. This MCP is limited to managing variables and listing existing services.

  • 02

    Will the AI delete my whole project?

    No. The agent can only delete specific variables, not entire services or projects.

  • 03

    Does the AI see my actual secret values?

    The agent can list variables, but it only interacts with the keys and values you explicitly tell it to manage.

  • 04

    Can I use this to change my domain settings?

    No. The current tools only allow for service listing and variable management.

  • 05

    Do I need to keep the Railway dashboard open?

    No. Once connected, you can perform all these actions directly through your AI client.
