Railway MCP

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.

Untrusted display-only summary

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.

Untrusted display-only summary

List all Railway projects accessible to the authenticated user

Untrusted display-only summary

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.

Untrusted display-only summary

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.

Untrusted display-only summary

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. Sealed variables are always listed by name wi…

Untrusted display-only summary

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

Untrusted display-only summary

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.

Untrusted display-only summary

Re-run the most recent deployment of a service in a given environment, reusing that deployment's existing build. Only works on a service that has already deployed in that environment — check with list-deployments if you are unsure. This does NOT give a service its first deployment: if it has never deployed, nothing he…

Untrusted display-only summary

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) or services with attached volumes unless th…

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.

Untrusted display-only summary

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

Untrusted display-only summary

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 tr…

Untrusted display-only summary

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). Pas…

Untrusted display-only summary

Update a volume's name and/or mount path. A mount path change redeploys the affected service so the new mount takes effect. Only the fields you pass are changed. Pass staged: true with an environmentId to stage the mount change in that environment's pending changes instead of applying it live; the volume's name is not…
