Railway MCP connector

• Action Whoami Get the current authenticated Railway user's profile information
• List List workspaces List the Railway workspaces the current user belongs to. Use a workspace ID with create-project to choose where a project is created.
• List List projects List all Railway projects accessible to the authenticated user
• Create Create project Create a new Railway project
• Create 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…
• Create 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). Public images only: credentials for a private registry are not accepted here — the user sets them on the service in the Railway…
• Update Update service Update a service's configuration: build/start/pre-deploy commands and pre-deploy timeout, builder, healthcheck, sleep mode, root directory, cron schedule, Dockerfile path, restart policy, config file path, watch patterns, replicas per region, resource limits, deployment…
• Delete 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…
• Create Create function Create a Railway Function: a service that runs one file of TypeScript on the Bun runtime, with no repository, Dockerfile or build step. Use this for webhook receivers, small HTTP APIs, cron jobs and scripts. Pass the complete code — a function with no code deploys nothing.…
• Update Update function source code Replace a Railway Function's source code. Send the complete file — this overwrites the function's code, it does not patch it, so anything you leave out is gone. Read the current code with get-function-source-code first if you are modifying rather than rewriting. Applies live…
• Get Get function source code Get a Railway Function's source code and runtime in an environment. Works for a function that is deployed and for one that exists only as a staged change — `code` is whichever is current, `deployedCode` is what is actually running, and `staged` says whether a commit is…
• List List services List the ids and names of all services and environments in a Railway project. Prefer describe-environment for what is actually in an environment: it includes volumes, buckets, deployments and staged changes.
• Describe 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…
• Describe 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, the latest deployment, and its tracing state.…
• Get 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…
• Get Get service config Prefer describe-service: it applies the staged changes 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,…
• Get 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.
• List List variables 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.…
• Set Set variables 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 ${{Postgres.DATABASE_URL}} is supported. Affected…
• Create Create volume Create a persistent volume in a project and optionally attach it to a service at a mount path. The attach and redeploy are committed together so the service comes up with the mount applied. Pass staged: true to stage the volume in one environment instead of provisioning it live.
• Update Update volume Update a volume's name, mount path, or which service it is attached to. Pass serviceId with mountPath to attach or move the volume; pass serviceId: null to detach it from its service, keeping the data. Every mount change redeploys the affected service so it takes effect. Only…
• Delete Delete volume Permanently delete a volume and its data. The volume is unmounted from any service it is attached to (redeploying that service). By default it is removed from every environment; pass an environmentId to remove it from that one environment only. Pass staged: true to stage the…
• Create Create bucket Create an S3-compatible object storage bucket in a project and provision it in an environment. Default region is sjc. Pass staged: true to stage the bucket in the environment's pending changes instead of provisioning it live — it then only becomes real when the staged changes…
• Update Update bucket Rename a bucket. The name is project-wide (not per environment) and takes effect immediately. Reference variables address the bucket by name (${{BucketName.ACCESS_KEY_ID}} and so on), so after a rename update any service variables that reference the old name and redeploy those…
• Delete 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…
• Get Get bucket credentials Get the S3-compatible connection details for a bucket in an environment: endpoint, bucket name, region, URL style, access key and secret. With a Railway session or API token the access key and secret are returned in plaintext; connected OAuth apps receive the connection…
• Action Reset bucket credentials Regenerate the S3-compatible credentials for a bucket in an environment and return the new ones. The current access key stops working immediately; bucket data is not affected. Every client using the old key needs the new values, and services that reference the bucket through…
• List List domains 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.
• Action 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…
• Generate 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…
• Update Update domain Repoint or rename an existing domain on a service. targetPort changes which container port the domain routes to (for a service listening on several ports). subdomain renames a Railway-generated service domain to <subdomain>.up.railway.app; custom domains cannot be renamed —…
• Delete Delete domain Remove a domain from a service: a Railway-generated *.up.railway.app service domain or a custom domain. Requests to that hostname stop being routed to the service as soon as the removal applies. Pass staged: true to stage the removal of a service domain in the environment's…
• Action Retry domain certificate Request a new TLS certificate for a custom domain whose issuance failed. Use domain-status first: it reports the certificate error and whether a retry can help (certificate.retryable). A retry cannot succeed until the domain's DNS records point at Railway. Railway-generated…
• Search Search docs 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.
• Action 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.
• Search Search templates Search the Railway template marketplace by name, description or keyword — databases (postgres, mysql, mongo, redis, clickhouse), their high-availability variants, and application templates. Returns published templates ranked by relevance. Use describe-template to read a…
• Describe Describe template Read one Railway template: its name, description, README, the services it creates, every env-var input it takes (which are required and which are optional), and — for clustered database templates like postgres-ha — the HA topology counts deploy-template can size. Call this…
• Action Deploy template Deploy a Railway template into a project — a database (postgres, mysql, redis, mongo), a clustered high-availability database, or an application template. Creates every service the template declares, wired together, and deploys them. Pass staged: true to stage them for the…
• List List feature flags 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.
• Get Get feature flag Get a Railway feature flag (Signal) by name for a project or its parent workspace scope.
• Set Set feature flag Create a project-scoped feature flag or update its default value, optionally replacing its targeting rules. Use list-feature-flags and get-feature-flag to inspect existing flags first.
• Delete Delete feature flag Delete a project-scoped feature flag. Workspace-scoped flags cannot be deleted from project context.
• List List deployments List recent deployments for a Railway project, optionally filtered by environment, service, or status. Returns the most recent first, with who triggered each one, its regions, and whether it can be redeployed or rolled back.
• Get 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…
• Get Get logs Get logs from Railway — deploy (runtime), build, http (proxy request), network-flow (per-connection egress/ingress) and dns (name lookups) streams. Pass a deploymentId to read one deployment, or serviceId (+ optional environmentId) to read the service's logs across its recent…
• List List traces List distributed traces of an environment, newest first — one row per request that has at least one span matching the filter. Use it to find slow or failing requests across services, then call get-trace with a traceId for the spans. Defaults to the last hour. If environmentId…
• Get Get trace Get the spans of one distributed trace, as a tree from the edge down through every service that handled the request. Find trace IDs with list-traces. Only spans belonging to the environment are returned. If environmentId is omitted, the production environment is used.
• Get Get tracing Read the tracing settings of an environment's services: whether each is traced and its auto-instrumentation switch. Pass serviceId for one service, omit it for every service in the environment. Tracing is set per service and environment; if environmentId is omitted, the…
• Get Get tracing coverage Report what one service's own instrumentation covers: the spans its app exported in the window, by span kind, by the remote system they name (database, cache, queue, RPC or HTTP client) and by the instrumentation library that emitted them. Use it after instrumenting a service…
• Set Set service tracing Enable or disable tracing and auto-instrumentation for one service in one environment, each independently. tracingEnabled switches whether the edge traces requests to the service and whether its next deploy gets the OpenTelemetry exporter variables. autoInstrumentationEnabled…
• Action 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…
• Action 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…
• Action 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.
• Action Redeploy Re-run the most recent deployment of a service in a given environment, reusing that deployment's existing build. Pass deploymentId to redeploy an earlier deployment's build instead (list-deployments has the ids). Only works on a service that has already deployed in that…
• Restart Restart service Restart a service's running deployment in place — the containers restart without rebuilding the image, and no new deployment is created (use redeploy for a fresh build copy). Restarting causes brief downtime; do NOT restart database services (Postgres, MySQL, Redis, MongoDB)…
• Get 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…
• Action 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. Also includes `pendingWork`: the environment's pending (staged/applying) work…
• List List tcp proxies List the TCP proxies exposing a service over the public internet on a raw TCP port (e.g. a database's public endpoint). Returns the public endpoint (host:port) and the application port each proxy forwards to.
• Create 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:…
• Delete 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…
• Action 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.…
• List List webhooks List a project's webhooks: for each, the URL Railway POSTs to, the deployment, monitor and volume-alert events that trigger it, whether it covers preview (PR) environments, the names of its custom headers (values are write-only), and its ID for update-webhook and delete-webhook.
• Create Create webhook Create a project webhook: Railway POSTs a JSON payload to the URL whenever one of the chosen deployment, monitor or volume-alert events happens in the project. Defaults to the deployment failure events (failed, crashed, out of memory) across regular and preview environments.…
• Update Update webhook Change a project webhook's URL, the events that trigger it, or whether it covers preview (PR) environments. Only the fields passed change; eventTypes replaces the whole set. Custom headers the user set in the Railway dashboard are kept as they are — this tool does not take…
• Delete Delete webhook Delete a project webhook so Railway stops POSTing to its URL. Get the webhook ID from list-webhooks. This cannot be undone; create-webhook makes a new one.
• Test Test webhook POST a sample event payload to a URL and report the HTTP status it answered with, to check a webhook endpoint before creating or after updating a webhook. Pass a URL to try a new endpoint, or a webhookId to send to an existing webhook with its stored URL and any custom headers…
• Accept Accept deploy DESTRUCTIVE: Commits all staged changes in a Railway environment and triggers a deploy. Only use this when the user has explicitly confirmed they want to deploy.
• Action Railway agent Hand a multi-step task in one project environment to Railway's own AI agent, for work too open-ended for the direct tools: investigating a failing deploy across services, or planning and making a set of related changes. The agent reads the environment's config, logs, metrics…
