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.
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!
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.
New dashboard layout, DNS management, queries for all databases, smart diagnosis
*What do we want?* A more sensible dashboard layout! *When do we want it?* Now! *Ok! I mean did you even read the changelog? It’s already available.* How can I have already read the changelog if I’m *currently* reading the changelog? *Oh right. Well, yes. Let’s get into it!* Let’s go!

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.
