name: railway description: Manage Railway projects, services, deployments, environments, variables, and deployment logs via Railway's public GraphQL API — one endpoint, relay-style pagination, two token flavors (account vs project), typed mutations for deploys and env vars. Use when the user wants to deploy, check service status, manage env vars, or read deployment logs programmatically without the Railway MCP installed. license: MIT (skill wrapper; Railway API terms apply)

Railway

Operates Railway via its public GraphQL API. Covers projects, environments, services, deployments, variables, logs. Prefer over railway CLI for typed, filterable reads pipeable through jq.

Usage

• Use for: Listing projects/services/deploy status, tailing deployment logs, upserting env vars, triggering redeploys from scripts.
• Skip for: New-account setup, billing/plan changes, first-time GitHub OAuth, short interactive sessions where railway CLI is faster.

Credentials check

[ -n "$RAILWAY_TOKEN" ] && echo "RAILWAY_TOKEN: PRESENT" || echo "RAILWAY_TOKEN: MISSING"

Never echo the variable directly.

If MISSING, respond to the user with EXACTLY this message (do NOT paraphrase, do NOT suggest manual JSON edits):

I need your railway credential. Run this in another terminal — it'll open the signup page, validate format, and save it safely with masked input:

teleport-setup add-key railway

Then restart Claude Code (/exit, then claude) and ask me again.

Do NOT suggest editing ~/.claude/settings.local.json manually. The teleport-setup add-key command handles it with backup, validation, and masked input. Stop execution until the user has run the command and restarted.

API

• Endpoint: https://backboard.railway.com/graphql/v2 — single endpoint, POST only, Content-Type: application/json.
• Auth: Authorization: Bearer $RAILWAY_TOKEN (account/workspace/OAuth tokens).
• Token flavors: account/workspace/OAuth use Authorization: Bearer; project tokens use Project-Access-Token: <TOKEN> (NOT Bearer) and see only one project+env. This skill assumes $RAILWAY_TOKEN is an account token.
• Rate limits: 100/1000/10000 RPH (Free/Hobby/Pro), 10/50 RPS (Hobby/Pro). Inspect X-RateLimit-Remaining, Retry-After.
• GraphQL envelope: { "data":{...}, "errors":[...] }. HTTP 200 even on failure — always check .errors. Variables go in top-level variables, not interpolated. Relay-style { edges:[{node}], pageInfo } on lists.
• Introspection enabled; GraphiQL at https://railway.com/graphiql.

Entity hierarchy

Workspace → Project → Environment + Service → Deployment. Variables scoped by triple (projectId, environmentId, serviceId); omit serviceId for project-shared.

Queries & mutations

Primary workflows

All calls: POST to $URL=https://backboard.railway.com/graphql/v2 with $H = -H "Authorization: Bearer $RAILWAY_TOKEN" -H "Content-Type: application/json".

1. List projects, environments, services

curl -sL -X POST $H "$URL" \
  -d '{"query":"query Me { me { projects(first:20){ edges{ node{ id name environments{ edges{ node{ id name } } } services{ edges{ node{ id name } } } } } } } }"}' \
  | jq '.data.me.projects.edges[].node | {id, name, envs:[.environments.edges[].node.name], services:[.services.edges[].node.name]}'

Save each environment.id / service.id — every mutation needs them; IDs are opaque UUIDs.

2. Upsert env vars (bulk)

curl -sL -X POST $H "$URL" \
  -d '{"query":"mutation($input:VariableCollectionUpsertInput!){ variableCollectionUpsert(input:$input) }","variables":{"input":{"projectId":"proj_xxx","environmentId":"env_xxx","serviceId":"svc_xxx","variables":{"LOG_LEVEL":"debug"},"replace":false,"skipDeploys":false}}}'

replace:true wipes vars not in payload; skipDeploys:true upserts without redeploying.

3. Trigger a deploy

curl -sL -X POST $H "$URL" \
  -d '{"query":"mutation($s:String!,$e:String!){ serviceInstanceDeploy(serviceId:$s, environmentId:$e) }","variables":{"s":"svc_xxx","e":"env_xxx"}}'

Confirm via deployments(input:{serviceId:$s}, first:1). Status: Initializing → Building → Deploying → Active/Completed (or Failed/Crashed). Poll ≥5s.

Gotchas

• GraphQL errors return HTTP 200. Always check .errors before trusting .data; curl -f won't save you.
• Account vs project tokens silently mismatch. Different header names and different scopes. A project token used as Bearer, or cross-project queries on a project token, fail with opaque auth errors.
• Variable scope is a triple (projectId, environmentId, serviceId). Omitting serviceId creates a project-shared var; per-service inheritance depends on settings — don't assume propagation.
• Mutation names drift. Railway has renamed deployment mutations (older deploymentTriggerCreate → current serviceInstanceDeploy). "Field not found" → re-check the cookbook. <!-- unverified -->
• Log rate limits are tight. Don't poll deploymentLogs in a tight loop; one read per 5–10s, increase limit instead.
• Relay cursor pagination. List fields return { edges:[{node}], pageInfo:{endCursor, hasNextPage} }. Use first:N, after:"<cursor>"; always pass first explicitly.
• Use introspection. Point GraphiQL at the endpoint with your token and auto-complete the schema instead of guessing.
