API capability pack for bounded Railway Public API GraphQL operations against https://backboard.railway.app/graphql/v2. Enroll a Railway account, workspace, or OAuth bearer connection named railway, or a project-token connection that injects Project-Access-Token when your enrollment flow supports Railway project tokens. Reads authenticated user/workspace context, projects, project members, environments, services, service instances, deployments, deployment/build logs, domains, volume instances, and volume backups for deployment operations and incident review. Approval-gated writes are limited to creating one project, creating one service, deploying or redeploying one service instance, restarting/rolling back/stopping/canceling/redeploying one deployment, creating one custom or Railway service domain, creating one volume, creating one volume backup, or restoring one selected backup at a time. The pack intentionally excludes arbitrary GraphQL passthrough, variable reads/writes, storage bucket credentials, API token administration, OAuth app administration, workspace/team/project membership and permission mutation, billing/usage mutation, environment change-set mutation, service/domain/project/environment/volume/deployment deletion, deployment approval, private registry credential mutation, and webhook/trigger administration.
