Railway MCP servers: which one to use
Use Railway's own server. You sign in through the Railway CLI or OAuth with no token to paste. Pick a community server only if you want an API token.

Railway runs its own MCP server at mcp.railway.com, and it is the right default. It lets an AI assistant create projects, deploy templates, manage environments, pull variables and redeploy services. You connect through the Railway CLI, which reuses your railway login, or with OAuth in editors that support it. The old Railway server on GitHub is archived, so ignore search results that point to it.
Good for
- Developers who want Claude Code or Cursor to deploy and redeploy services
- Teams who need to pull environment variables or debug a failing deploy from chat
- Anyone who prefers a project-scoped token over signing in
- People on locked-down networks who need a server that runs on their own machine
Which Railway MCP server to use
Use Railway's own server: it signs in with your Railway account and lets you choose which workspaces and projects it can reach. Choose crisog's for more tools on a workspace or project token, or jason-tan-swe's, the most starred community server.

Questions
Is there an official Railway MCP server?
Yes. Railway runs it at mcp.railway.com. You connect through the Railway CLI, which needs version 5.44.0 or later, or with OAuth in editors that support it.
Is the old railway-mcp-server repo still the official one?
No. The railwayapp/railway-mcp-server repository is archived on GitHub, and Railway's docs now describe the hosted server. Use the docs, not the old repo.
Does it work in Claude?
Yes. Railway is in Claude's connector directory, and that listing names 16 tools. Railway's docs name Cursor, VS Code, Claude Code and Windsurf as hosts, and railway mcp install writes the setup for supported editors.
Do I need a Railway API token?
Not for the official server. With OAuth you choose which workspaces and projects the client can reach, and the tokens are short-lived and revocable. The docs say project tokens are not accepted. The community servers use a Railway API token.
Can it delete or break my deployments?
Yes. It can redeploy services and deploy staged changes, and the hosted tools include deleting a feature flag. Railway marks destructive tools so clients ask before running them, and its docs advise limiting use to non-critical environments.
Can I run the official server on my own machine?
Yes. Railway's docs say the CLI ships a local server for networks that cannot reach mcp.railway.com. The local server exposes a different set of tools than the hosted one, including removing services and deleting domains.
Which community server has the most tools?
crisog's, with 51 tools in its README. It takes an account, workspace or project token, and its README advises the narrowest scope. jason-tan-swe's README lists 24 tools and says not all features are available yet.
Are the community servers still maintained?
Check the repos before relying on them. jason-tan-swe's is the most starred at 72, but its last commit is June 2025. crisog's has 2 stars and its last commit is November 2025.
