Railway MCP Server

What Railway MCP Server does

Railway MCP Server gives AI agents an MCP interface to Railway projects and deployments. Its supported scope covers deploying services, managing Railway environments, updating variables, and reading logs. These capabilities make it relevant for development and operational workflows where an agent needs to inspect or change a Railway-hosted application.

The server is focused on Railway rather than providing a general cloud-management interface. Reach for it when Railway is the platform being used and the agent needs access to service or environment operations.

How it works

Two connection paths are available. The hosted server uses OAuth, allowing an MCP client to connect through Railway's hosted service. Alternatively, the Railway CLI can start the server locally with the railway mcp command.

The choice depends on how the client is managed. A hosted connection avoids running the MCP process locally, while the CLI-based option keeps the server in the local development environment. In both cases, an MCP-compatible AI agent can use the exposed Railway operations through its normal tool interface.

Setup and configuration

For the hosted option, connect the MCP client to Railway's hosted server and complete the OAuth flow. Authentication is handled through OAuth rather than a manually configured variable listed for the server.

For local use, install and configure the Railway CLI, then launch the MCP server with:

railway mcp

The local command provides the MCP process that the client connects to. The hosted and local approaches are alternatives; choose the one that matches the client's connection model and the desired authentication workflow.

Tools and capabilities

The available operations cover four main areas:

• Deploy Railway services.
• Manage Railway services.
• Manage Railway environments.
• Create or update Railway variables.
• Read service logs.

Together, these tools support an agent-assisted loop of inspecting logs, changing configuration, managing environments, and deploying services on Railway.

Limitations and notes

This server is specific to Railway resources and workflows. Its documented capabilities center on services, environments, variables, deployments, and logs, so it is best suited to tasks within a Railway project rather than cross-provider infrastructure management. Authentication differs by connection method: the hosted endpoint uses OAuth, while the local option runs through the Railway CLI.
