Antigravity plugin

The Railway plugin for Google Antigravity packages the use-railway skill with Railway's hosted MCP server. It connects Antigravity to Railway workflows for deployments, configuration, monitoring, and troubleshooting.

Install from the source repository

Clone the Railway skills repository, then install the plugin from its plugins/railway directory.

git clone https://github.com/railwayapp/railway-skills.git
agy plugin install ./railway-skills/plugins/railway

Run agy plugin list to confirm that railway is installed and enabled.

To install from the Antigravity app instead:

Click Customizations in the sidebar, then select Plugins.
Click + Install from URL.
Enter the local path to railway-skills/plugins/railway.

Connect your Railway account when Antigravity prompts you to authenticate the Railway MCP server.

Use Railway in Antigravity

Invoke the skill directly with /use-railway, or ask Antigravity to work with Railway:

Deploy this app to Railway
Check the Railway status for this project
Debug my latest failed Railway deployment

What's included

The Antigravity plugin installs these components:

The use-railway skill provides Railway-specific workflows for setup, deployment, configuration, and operations.
The hosted Railway MCP server provides authenticated access to Railway projects and infrastructure. Antigravity lists it as railway-mcp.

To configure the MCP server without the plugin, run railway mcp install --agent antigravity. See railway mcp.
