railway mcp adds an experimental local MCP server
Introduced 2026-03-18 · score 0.98
HOW TO USE IT
If the repository coding task requires managing Railway projects, start the experimental local MCP server with `railway mcp`; it serves MCP over stdio. Use the tools exposed by that server for supported Railway operations.

Determine whether the experimental Railway MCP server applies to a repository coding task that requires managing Railway projects.
REQUIREMENTS AND LIMITATIONS
- Version: v4.32.0
- Availability: Experimental and subject to change.
- Prerequisite: The command initializes Railway CLI configuration and an authorized GraphQL client; authenticate the CLI before starting the server. The v4.32.0 command has no command-line arguments.
- MCP server runs locally over stdio.
- Docs conflict: Current Railway CLI docs describe bare `railway mcp` as a hosted MCP proxy and use `railway mcp local` for the GraphQL-backed local server. That differs from v4.32.0, whose command starts a local stdio server; current behavior must not be substituted for the card's version.
