Releasesby GlyphRailway Agent, IPv6 Support
If an AI can tell you why your deploy is red, it should be able to make it green. This week, the Railway Agent is live for every workspace. It can create services, connect databases, walk you through a red deploy, and open a pull request with the fix, all from a chat panel in the Railway dashboard.

Undoable volume deletes, standard SSH, auto-deploy toggle
One `curl` shouldn't be enough to wipe a production database, [especially when an agent is the one firing it off](https://blog.railway.com/p/your-ai-wants-to-nuke-your-database). This week, volume deletions over the API soft-delete for 48 hours, matching the safety net the dashboard already had.
Remote MCP, Railway Agent in the CLI, one-command skills install
If your agent can write the code, it should be able to ship it too. So this week, we laid three new tracks for it. The Railway Remote MCP Server is now live at [`mcp.railway.com`](https://mcp.railway.com), ready for any MCP-compatible editor to plug into over OAuth.
Easy agent setup, railway scale TUI, unified template search
If your agent can deploy services, set variables, and read logs, it should also be able to discover templates and scale replicas on its own. This week, one command sets up your CLI, agent skills, and MCP server in one shot. Template search now works the same way everywhere: dashboard, canvas, command palette, and CLI all share one backend.
Railway Goes to the Land of Torii Gates and Cherry Blossoms
This week, the fully remote Railway team descended on Kyoto, Japan for our biannual retreat, a week dedicated to planning, in-person collaboration, and exploring one of the most beautiful cities in the world.
Railway for iOS, CLI metrics, Postgres PITR
This week, the Railway iOS app [landed in TestFlight](https://railway.com/mobile)! You can spin up services, get notified if anything goes wrong, read logs, view metrics, and deploy fixes, all from your pocket. No more keeping a laptop within arm's reach every weekend.
Skip rebuilds, Guardrails, better CLI
The best build is the one that never runs. This week, Railway can detect when identical source code has already been built and skip the build entirely, deploying the cached image in seconds.
Railway Agent sandbox, HA static egress, GitHub org guardrails
We gave the Railway Agent a computer. The chat agent now gets a sandbox VM of its own, so it can clone a repo, run commands, edit files, and open a pull request without you copy-pasting code into the conversation. Static IP egress now supports high-availability with traffic distributed across three gateways and automatic failover.
One-click CDN, Railway x Stripe Projects, HA Postgres
Your users in Tokyo shouldn't wait for bytes to travel from us-west. Starting this week, they don't have to. We're shipping a built-in CDN you can enable in one click, a partnership with Stripe that lets agents provision Railway in one command, and a one-click path to high-availability Postgres for everyone. Let's get into it!
