Railway

Get a service's configuration in an environment: source (repo/image), build settings, deploy settings (start command, healthcheck, replicas, cron, restart policy), networking, and volume mounts. Variable names are listed but values are not included — use list-variables for values. If environmentId is omitted, the production environment is used.

get-service-config

Get resource usage metrics (CPU, memory, disk, network) for a service, summarized as current/average/min/max over a time window. Defaults to CPU_USAGE and MEMORY_USAGE_GB over the last hour. If environmentId is omitted, the production environment is used.

get-service-metrics

List recent deployments for a Railway project, optionally filtered by environment, service, or status. Returns the most recent first.

list-deployments

List all domains (Railway-generated service domains and custom domains) for a service in an environment. If environmentId is omitted, the production environment is used.

list-domains

List Railway feature flags (Signals) for a project and optionally the parent workspace. Project flags are editable with admin access; workspace flags are read-only from project context.

list-feature-flags

List all Railway projects accessible to the authenticated user

list-projects

List all services and environments in a Railway project

list-services

List all environment variables for a service, fully rendered (reference variables like ${{Postgres.DATABASE_URL}} are resolved). With a Railway session or API token, values are returned in plaintext and may contain secrets. Connected OAuth apps receive variable names only. If environmentId is omitted, the production environment is used.

list-variables

List the Railway workspaces the current user belongs to. Use a workspace ID with create-project to choose where a project is created.

list-workspaces

Send a message to Railway's AI agent for complex infrastructure operations. The agent can inspect services, diagnose issues, and take actions on your behalf.

railway-agent

Trigger a redeployment of a service in a given environment

redeploy

Search the Railway documentation (docs.railway.com) for features, configuration, guides, and tutorials. Returns matching sections with URLs — use fetch-docs to read a full page.

search-docs

Create a project-scoped feature flag or update its default value. Use list-feature-flags and get-feature-flag to inspect existing flags first.

set-feature-flag

Set one or more environment variables on a service (or environment-wide shared variables when serviceId is omitted). Existing variables with the same name are overwritten; others are left unchanged. Reference syntax like ${{Postgres.DATABASE_URL}} is supported. Affected services are redeployed unless skipDeploys is true.

set-variables

Update a service's configuration: build/start/pre-deploy commands, healthcheck, sleep mode, root directory, cron schedule, Dockerfile path, restart policy, config file path, and watch patterns. Only the fields you pass are changed. Changes apply on the service's next deployment (use redeploy to apply immediately). Scaling (replicas/regions) and source changes are not handled by this tool.

update-service

Get the current authenticated Railway user's profile information
