Introduction

Claude is Anthropic's AI assistant, available on the web, in the desktop app, and on mobile. Cowork is its agent for knowledge work, and it runs on all of those surfaces too. Connected to your apps, Claude can work with your files and services to accomplish complex tasks on your behalf.

This guide walks you through the easiest and most secure way to connect your Railway account to Claude via Composio Connect, enabling it to list recent failed Railway deployments, redeploy production service on Railway, check Railway project environment variables, and more such actions on your behalf without compromising your account security.

Setup is the same on Claude Web, Desktop, and Cowork, and you only need to do it once. The connector is tied to your account, so it's available in all three.

Two ways to add the Composio connector. Pick whichever you prefer.

1. Add with one click

Click the button. Claude opens with the Composio connector filled in. Click Add, then go to step 2.

Add to Claude

Add manually

In Claude Desktop, click Customize in the left sidebar, then select Connectors and click the + icon at the top.

Click Add custom connector and paste in the Composio MCP server URL:

bash
https://connect.composio.dev/mcp
Add custom connector dialog with Composio MCP server URL

2. Authorize in your browser

Click Connect. You'll be redirected to a browser window where you can authorize Composio to continue.

3. Connect your Railway account

Back in Claude, ask it to connect to Railway or give it any Railway-related task.

For example, ask Claude to:

  • "List recent failed Railway deployments"
  • "Redeploy production service on Railway"
  • "Check Railway project environment variables"

It will prompt you to authenticate and authorize access.

That's it. Composio's tools are now available in Claude, and your Railway account is ready to use.

What is the Railway Claude Connector, and what's possible with it?

The Railway MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Railway account. It provides structured and secure access to your projects, environments, services, deployments, logs, metrics, domains, and storage, so your agent can create infrastructure, deploy services, monitor performance, troubleshoot failures, and manage resources on your behalf.

  • Project and environment setup: Have your agent create projects, build or clone environments, review staged changes, and commit approved environment updates.
  • Service and deployment management: Let the agent create services from repositories, images, or templates, start deployments, check their status, cancel builds in progress, or remove completed deployments.
  • Logs and troubleshooting: Direct your agent to inspect build, runtime, and HTTP logs, collect deployment evidence, and review deployment details when something goes wrong.
  • Performance monitoring: Instruct your agent to examine HTTP traffic, response times, CPU, memory, disk, network, backup, and volume metrics for your Railway services.
  • Domains, networking, and storage: Have your agent create or remove domains, configure buckets and private networking, and create, attach, or delete persistent volumes.

Troubleshooting

1. Why does Claude not use the Composio connector for Railway?

The connector can show as connected, but Claude must use it in each Railway conversation.

  • Click + at the lower left of the chat, or type /.
  • Hover Connectors.
  • Turn on Composio.
  • Ask Claude to connect to Railway again.

2. Why does Claude show an MCP server error before Railway connects?

Claude can show Couldn't reach the MCP server or Authorization with the MCP server failed when you add the connector for Railway.

  • Check that the connector URL is https://connect.composio.dev/mcp.
  • Connectors run from Anthropic's cloud, so your device network is usually not the problem.
  • Add the connector again from Customize > Connectors, then ask Claude to connect Railway.
  • If it fails again, send the error and the ofid_ reference id to support@composio.dev.

3. Why does the Railway authorization link not work?

The Composio connector is one server. Your Railway account connects separately when Claude asks for it.

  • If the browser does not open, or the link expires, ask Claude to retry the Railway connection.
  • Composio creates a fresh Railway authorization link.
  • Open that link in your browser and finish the Railway sign-in.

4. Why do Railway actions fail after they worked before?

The Railway connection can expire or lose permission.

  • Ask Claude to inspect the Railway connection.
  • If the connection is unhealthy, disconnect it when Claude prompts you.
  • Reconnect the Railway account and retry the action.
  • If Claude shows a permission prompt, approve it before Claude changes data in Railway.
  • If the action still fails with a permission error, check that the connected account has that permission in Railway itself.

5. How do I switch to a different Railway account?

Claude can manage the Railway connection for you.

  • Ask Claude to disconnect or delete the current Railway account.
  • Ask Claude to connect Railway again.
  • Open the new Composio authorization link for Railway.
  • Sign in with the other Railway account in the browser.
  • After the account connects, ask Claude to retry the Railway task.

6. Why is my Railway connection missing in Claude Desktop or on a Team plan?

The connector belongs to your Claude account, so your Railway connection works in Claude Web, Desktop, and Cowork.

  • In Claude Desktop, open Customize > Connectors.
  • Next to Composio, click ⋮ and click Clear cache.
  • If Railway tools still do not appear, click ⋮, disconnect, remove the connector, and add it again.
  • On Team or Enterprise, an Owner or Primary Owner must enable the connector before you can connect Railway.

FAQ

Frequently asked questions

With a standalone Railway MCP server, the agents and LLMs can only access a fixed set of Railway tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Railway and many other apps based on the task at hand, all through a single MCP endpoint.

Yes, you can. Claude Cowork fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Railway tools.

Yes, absolutely. You can configure which Railway scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Railway data and credentials are handled as safely as possible.
