Grok Build + Railway

Grok Build is xAI's CLI-first coding agent. It plans before it edits — Plan Mode blocks changes until you approve — runs subagents in parallel, and speaks MCP out of the box. Paired with Railway, Grok Build can provision services, set variables, deploy, and read logs without leaving the terminal.

Quick start

1

Install Grok Build

Install the Grok Build CLI and sign in with your SuperGrok or X Premium+ account

curl -fsSL https://x.ai/cli/install.sh | bash
2

Install Railway CLI

Install Railway CLI and authenticate

npm install -g @railway/cli && railway login
3

Open your project

Start Grok Build in your repo. It opens in Plan Mode so you approve changes before they run

4

Deploy a Go API with Redis

Grok Build plans the steps, then on approval deploys with railway.com/template/gin + Redis

Deploy this to Railway with a Redis cache for rate limiting

Example prompts

Find latest information from railway on X and create a video based on them

Add Redis for caching API responses

Check the failing health check and fix it

Set up environment variables from my .env.example file

Configure the service to scale to zero when idle

Add a cron service that sends daily email digests

Deploy Plausible Analytics with Postgres and Clickhouse

Set up a Langchain app with Postgres (pgvector) for RAG

Deploy Grafana connected to my Railway metrics

Create a complete auth system with Keycloak and Postgres

Common workflows

1Plan then deploy

  1. Ask Grok Build to deploy the app to Railway
  2. Review the plan Grok Build proposes in Plan Mode
  3. Approve the plan to let it run railway up
  4. Grok Build reports the deployment URL and status

2Provision a Postgres database

  1. Ask Grok Build to add Postgres to your project
  2. Grok Build runs railway add for the database
  3. It wires DATABASE_URL into your service variables
  4. Grok Build redeploys and confirms the connection

3Parallel service scaffolding

  1. Ask Grok Build to stand up an API and a worker
  2. It fans out subagents to scaffold each service
  3. Each subagent deploys its service to Railway
  4. Grok Build reports both deployments when done

4Headless CI deploy

  1. Run Grok Build in headless mode from CI
  2. It reads railway.toml and deploys non-interactively
  3. Grok Build streams railway logs for the deploy
  4. The job fails fast if the deploy is unhealthy

Tips for success

  • Keep Plan Mode on so you approve edits before they run
  • Use subagents to scaffold multiple services in parallel
  • Grok Build speaks MCP — point it at Railway's MCP server

Frequently asked questions

How do I deploy to Railway with Grok Build?

Ask Grok Build to deploy to Railway. In Plan Mode it shows the steps (railway up, variables, domain) before running. Approve the plan and it executes and reports the deployment URL.

Can Grok Build use Railway's MCP server?

Yes. Grok Build supports MCP out of the box. Point it at Railway's MCP server so it can discover projects, read deployment status, and fetch logs natively.

Do I need a subscription to use Grok Build?

Grok Build is available to SuperGrok and X Premium+ subscribers. Sign in during install to authenticate the CLI.

Troubleshooting

Issue:

Grok Build won't apply edits

Solution:

Plan Mode blocks changes until you approve the plan. Review the proposed steps and approve them to let Grok Build proceed.

Issue:

Railway CLI not found in the Grok Build session

Solution:

Install the Railway CLI globally with npm install -g @railway/cli and restart your shell so railway is on PATH.

Issue:

Railway commands fail with permission denied

Solution:

Run railway login to re-authenticate, then retry the deploy.
