Railway Integration

Manage your Railway infrastructure using the Railway CLI. Deploy services, manage environment variables, check deployment status, and more.

Authentication

First, check if RAILWAY_API_TOKEN is configured:

key_name: RAILWAY_API_TOKEN

If not configured, ask the user to create a token at https://railway.com/account/tokens and add it in Settings > API Keys as RAILWAY_API_TOKEN.

The RAILWAY_API_TOKEN env var is automatically injected into all exec commands.

Prerequisites

Ensure the Railway CLI is installed:

command: railway --version
timeout: 30

Railway CLI is installed by the railway_cli module. If missing, reinstall via manage_modules(action="install", name="railway_cli").

Operations

1. Verify Authentication

Use railway list to verify auth (works with all token types — account, workspace, and project tokens). Do NOT use railway whoami as it only works with account tokens and will fail with workspace/project tokens.

command: railway list
timeout: 30

2. List Projects

command: railway list --json
timeout: 30

3. Get Project Status

After linking to a project (see operation #4), check its status:

command: railway status --json
timeout: 30

4. Link to Existing Project

Link the current workspace to a project so subsequent commands target it. Use --project and --environment flags to avoid interactive prompts:

command: railway link --project PROJECT_ID --environment ENVIRONMENT_ID
timeout: 30

5. Get Deployments / Logs

View recent deployment logs:

command: railway logs -n 50
timeout: 30

View build logs:

command: railway logs --build -n 100
timeout: 30

6. Trigger Redeploy

IMPORTANT: Confirm with the user before triggering a redeploy.

command: railway redeploy -y
timeout: 30

7. Get Environment Variables

command: railway variable list --json
timeout: 30

8. Set Environment Variables

IMPORTANT: Confirm with the user before modifying environment variables.

command: railway variable set KEY=VALUE
timeout: 30

For multiple variables:

command: railway variable set KEY1=VALUE1 KEY2=VALUE2
timeout: 30

9. Create Railway Domain

command: railway domain
timeout: 30

10. Deploy from GitHub Repo

Deploy a GitHub repository to Railway. This is a multi-step workflow.

IMPORTANT: Confirm the repo URL, project name, and branch with the user before proceeding.

Step 1: Define the tasks

Call define_tasks with all steps upfront so progress is tracked:

{"tool": "define_tasks", "tasks": [
  "TASK 1 — Create project: create a new Railway project. See railway skill 'Step 2'.",
  "TASK 2 — Add service from repo: add a service linked to the GitHub repo. See railway skill 'Step 3'.",
  "TASK 3 — Generate domain: assign a public .railway.app domain. See railway skill 'Step 4'.",
  "TASK 4 — Set env vars: configure environment variables if needed. See railway skill 'Step 5'.",
  "TASK 5 — Verify deployment: check logs and confirm service is live. See railway skill 'Step 6'."
]}

Step 2: Create a new project

command: railway init --name PROJECT_NAME
timeout: 60

This creates a project and links the current workspace to it.

Tip: If deploying into an existing project, use operation #4 (link) instead.

Step 3: Add service from GitHub repo

Option A: GitHub repo link (requires Railway GitHub App)

command: railway add --repo OWNER/REPO
timeout: 60

Replace OWNER/REPO with the GitHub repository (e.g. ethereumdegen/x402-gif-machine). Railway will automatically trigger an initial deployment.

If this fails with "repo not found", the Railway GitHub App doesn't have access. Fall back to Option B.

Option B: Clone and deploy (no GitHub App needed)

Clone the repo locally and deploy with railway up:

command: git clone https://github.com/OWNER/REPO.git /tmp/railway-deploy-REPO
timeout: 120

Then link and deploy from the cloned directory:

command: cd /tmp/railway-deploy-REPO && railway link --project PROJECT_ID --environment production && railway up --detach
timeout: 300

Note: Option B deploys a snapshot. It won't auto-deploy on new commits like Option A does. For auto-deploy, the user needs to configure the Railway GitHub App on their repo (GitHub → Settings → Applications → Railway → Configure).

Step 4: Generate a public domain

command: railway domain
timeout: 30

Step 5: Set environment variables (if needed)

Use operation #8 to set any env vars the service needs.

Step 6: Verify deployment

Check the deployment logs to confirm it built and deployed successfully:

command: railway logs --build -n 100
timeout: 60

Then check runtime logs:

command: railway logs -n 50
timeout: 30

11. Deploy from Local Directory

Deploy the current working directory to Railway:

command: railway up --detach
timeout: 300

Use --detach to avoid blocking while the build runs. Check logs separately.

12. Delete Service

IMPORTANT: Confirm with the user before deleting.

command: railway delete -y
timeout: 30

Error Handling

Token Types

• Account tokens (RAILWAY_API_TOKEN) — full access, works with CLI, preferred
• Project tokens — scoped to one environment, limited CLI support

Typical Workflow

1. Verify auth — railway list (NOT whoami — it only works with account tokens)
2. List projects — railway list
3. Link to project — railway link --project ID --environment ID
4. Check status — railway status
5. Take action — redeploy, update env vars, etc. (confirm with user first)

Best Practices

1. Always verify auth first before running other commands
2. Link before acting — use railway link so commands target the right project
3. Confirm mutations — always ask the user before redeploying or changing env vars
4. Use `--json` flag where available for structured output
5. Be careful with env vars — they may contain secrets, don't log values unnecessarily
