The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

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.

| 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) |

| 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 |
