Tool Tokens

check-railway-status Check Railway CLI Status ~43

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.

No output schema declared.

No examples provided.

get-logs Get Railway Logs ~400

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.

Input Output Examples

Name	Type	Req	Description
deploymentId	string	—	Deployment ID to pull logs from. Omit to pull from latest deployment
environment	string	—	Environment to view logs from (defaults to linked environment)
filter	string	—	Filter logs by search terms or attributes. Requires Railway CLI v4.9.0+. Examples: 'error', '@level:error', '@level:warn AND rate limit', 'user login', '@status:500'. See https://docs.railway.com/gui…
json	boolean	—	JSON provides structured log data with more information (e.g. timestamps) but uses more tokens. Defaults to false to save tokens. Set to true for more detailed logs.
lines	number	—	Number of log lines to return (disables streaming). Requires Railway CLI v4.9.0+. Useful for searching through recent logs.
logType	string	yes	Type of logs to retrieve: 'build' for build logs or 'deploy' for deployment logs
service	string	—	Service to view logs from (defaults to linked service)
workspacePath	string	yes	The path to the workspace to get logs from
