Railway MCP Server

Check whether the Railway CLI is installed and if the user is logged in. This tool helps agents verify the Railway CLI setup before attempting to use other Railway tools.

Create a new Railway environment for the currently linked project. Optionally duplicate an existing environment and set service variables.

Create a new Railway project and link it to the current directory

Search and deploy Railway templates. This tool will search for templates using fuzzy search and automatically deploy the selected template to the current Railway project and environment.

Upload and deploy from the current directory. Supports CI mode, environment, and service options.

Generate a domain for the currently linked Railway project. If a domain already exists, it will return the existing domain URL. Optionally specify a service to generate the domain for.

Get build or deployment logs for the currently linked Railway project. This will only pull the latest successful deployment by default, so if you need to inspect a failed build, you'll need to supply a deployment ID. You can optionally specify a deployment ID, service, and environment. If no deployment ID is provided, it will get logs from the latest deployment. The 'lines' and 'filter' parameters require Railway CLI v4.9.0+. Use 'lines' to limit the number of log lines (disables streaming) and 'filter' to search logs by terms or attributes (e.g., '@level:error', 'user', '@level:warn AND rate limit'). For older CLI versions, these parameters will be ignored and logs will stream.

Link to a specific Railway environment. If no environment is specified, it will list available environments for selection.

Link a service to the current Railway project. If no service is specified, it will list available services

List deployments for a Railway service with IDs, statuses and other metadata. Requires Railway CLI v4.10.0+.
