Connect-service-source
RAILWAY_MCP_CONNECT_SERVICE_SOURCE
Attach a source to an existing service: a GitHub repository (deploys on push, builds immediately) or a Docker image. This is how a service that has never deployed gets its first deployment, and how an existing service's source is switched. Provide exactly one of repo or image. By default it applies to the service in a…

Create-bucket
RAILWAY_MCP_CREATE_BUCKET
Create an S3-compatible object storage bucket in a project and provision it in an environment. Default region is sjc. Pass staged: true to stage the bucket in the environment's pending changes instead of provisioning it live — it then only becomes real when the staged changes are committed with accept-deploy.

Create-deployment
RAILWAY_MCP_CREATE_DEPLOYMENT
Create a new service from a GitHub repository and trigger its first deployment. The repo must be one the authenticated user has connected via GitHub. Returns the new service; use get-status or list-deployments to follow the deploy. Before calling this tool you MUST have a GitHub repo to deploy. If the user has not pro…

Create-service
RAILWAY_MCP_CREATE_SERVICE
Create a new service in a project from a Docker image, or an empty service to configure later (e.g. before setting variables and attaching a source). Pass staged: true to stage the service in one environment instead of applying it live — it then only becomes real when the staged changes are committed with accept-deplo…

Create-tcp-proxy
RAILWAY_MCP_CREATE_TCP_PROXY
Expose a service on the public internet over a raw TCP port (e.g. make a database reachable externally). Creates a TCP proxy forwarding a public endpoint to the given application port, applied through the environment config so the service redeploys with it active. Pass staged: true to stage the proxy in the environmen…
Untrusted display-only summary
Create-volume
RAILWAY_MCP_CREATE_VOLUME
Create a persistent volume in a project and optionally attach it to a service at a mount path. The attach and redeploy are committed together so the service comes up with the mount applied. Pass staged: true to stage the volume in one environment instead of provisioning it live.
Untrusted display-only summary
Delete-bucket
RAILWAY_MCP_DELETE_BUCKET
Permanently delete an object storage bucket and its contents. By default it is removed from every environment it is provisioned in; pass an environmentId to remove it from that one environment only. Pass staged: true to stage the removal in one environment instead of applying it live. Deleting from every environment i…

Delete-feature-flag
RAILWAY_MCP_DELETE_FEATURE_FLAG
Delete a project-scoped feature flag. Workspace-scoped flags cannot be deleted from project context.
Untrusted display-only summary
Delete-service
RAILWAY_MCP_DELETE_SERVICE
Permanently delete a service: its deployments stop and are removed, along with its domains, variables and deployment triggers. Any volume attached to it is detached and kept — delete-volume removes a volume and its data. By default the service is deleted in every environment that is not a fork; pass an environmentId t…
Untrusted display-only summary
Delete-tcp-proxy
RAILWAY_MCP_DELETE_TCP_PROXY
Remove a service's TCP proxy, taking its public endpoint offline. Anything connecting through that endpoint (e.g. external database clients) loses access. Pass staged: true to stage the removal in the environment's pending changes instead — that is also how a proxy that is itself only staged gets dropped again.
Untrusted display-only summary
Delete-volume
RAILWAY_MCP_DELETE_VOLUME
Permanently delete a volume and its data. The volume is unmounted from any service it is attached to (redeploying that service). By default it is removed from every environment; pass an environmentId to remove it from that one environment only. Pass staged: true to stage the removal in one environment instead of apply…

Describe-environment
RAILWAY_MCP_DESCRIBE_ENVIRONMENT
Inventory of everything in a Railway environment — services, volumes, buckets, shared variable names — with staged changes applied. Each resource carries a `state`: live, staged-create (exists only in the pending patch), staged-delete, or live-with-staged-changes. Includes each service's source, regions, replicas, cro…

Describe-service
RAILWAY_MCP_DESCRIBE_SERVICE
Everything about one service in an environment: its config with staged changes applied (source, build, deploy, networking, volume mounts), the per-field staged changes pending on it, mounted volumes, live domains and TCP proxies, and the latest deployment. `state` says whether the service is live, staged-create, stage…

Domain-status
RAILWAY_MCP_DOMAIN_STATUS
Get detailed status for one domain on a service, by hostname, URL, or domain ID: required DNS records and whether they currently match, ownership verification, certificate status, and any certificate error. Use list-domains first if you do not know which domains exist. If environmentId is omitted, the production envir…

Environment-status
RAILWAY_MCP_ENVIRONMENT_STATUS
Health overview of every service in an environment in one call: current LIVE (settled) deployment state, replica status, recent failures, unresolved warnings/criticals, and cron execution results. Does not include uncommitted staged patch work. By default only services with issues are returned — pass includeSuccessful…

Fetch-docs
RAILWAY_MCP_FETCH_DOCS
Fetch the full markdown content of a Railway documentation page by URL or slug (e.g. 'https://docs.railway.com/quick-start' or 'reference/variables'). Use search-docs first to find the right page.

Generate-domain
RAILWAY_MCP_GENERATE_DOMAIN
Expose a service publicly. Without `domain`, generates a Railway *.up.railway.app service domain (if the service already has domains, they are returned instead of creating another). With `domain`, attaches a custom domain you own and returns the DNS records the user must create for it to verify. If environmentId is om…

Get-deployment-diagnosis
RAILWAY_MCP_GET_DEPLOYMENT_DIAGNOSIS
Get the AI-generated diagnosis for a failed deployment: root cause category, analysis, and suggested fixes, along with deployment context (service config, source repo, branch, commit, PR, failure stage and error). Diagnoses run automatically when a deployment fails — if one isn't available yet, fall back to get-logs t…

Get-logs
RAILWAY_MCP_GET_LOGS
Get logs from Railway for a deployment — covers deploy (runtime), build, and http (proxy request) contexts. Pass a specific deploymentId, or pass serviceId + environmentId to resolve the latest deployment. Use `types` to choose which streams to return (default: ['deploy']).

Get-service-config
RAILWAY_MCP_GET_SERVICE_CONFIG
Prefer describe-service: it applies the staged diff onto the live config for you and adds mounted volumes, domains, TCP proxies and the latest deployment. Get a service's configuration in an environment: source (repo/image), build settings, deploy settings (start command, healthcheck, replicas, cron, restart policy),…

Get-service-metrics
RAILWAY_MCP_GET_SERVICE_METRICS
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.
Untrusted display-only summary
Get-staged-changes
RAILWAY_MCP_GET_STAGED_CHANGES
Show the changes staged in a Railway environment that accept-deploy would commit: per resource (service, volume, bucket, group) the action — create, delete, update — and each changed field with its live and staged value. Variable values and registry credentials are redacted to names. Also reports whether the patch is…

Get-status
RAILWAY_MCP_GET_STATUS
Prefer describe-environment: it also lists services that exist only in the staged patch, unattached volumes, and each resource's staged state. Get the deployment status of a Railway project environment. Returns project + environment metadata, whether the environment has undeployed staged changes, the environment's buc…

Http-error-rate
RAILWAY_MCP_HTTP_ERROR_RATE
Get the HTTP error rate for a service over time — the share of requests answered with a 5xx. Use this for reliability and to locate error spikes. 4xx responses are reported separately and are not counted in the rate, since a 404 or a rejected payload is usually the caller's doing. Defaults to the last hour. If environ…

Http-requests
RAILWAY_MCP_HTTP_REQUESTS
Get HTTP request counts for a service, bucketed over time and split by response status class (2xx/3xx/4xx/5xx). Use this for traffic volume and the mix of successful versus failing responses. Defaults to the last hour. If environmentId is omitted, the production environment is used.

Http-response-time
RAILWAY_MCP_HTTP_RESPONSE_TIME
Get HTTP latency percentiles (p50, p90, p95, p99) for a service, bucketed over time, in milliseconds. Use this for performance and to find slow requests. Defaults to the last hour. If environmentId is omitted, the production environment is used.
