SSH Rails Runner

Example Use Cases

• 1

  Run read-only Rails console queries on a remote deployment to inspect production data without risking changes.

• 2

  Prepare, store, and present Ruby code snippets (mutations or queries) for human review before executing changes in a Rails app.

• 3

  Integrate remote Rails execution into automated workflows (via SSH) while keeping a clear separation between dry-run review and final destructive execution.

Description

This MCP server connects to a remote Rails app over SSH and runs Ruby code (Rails console commands) from prepared code snippets. It supports safe read-only execution, a dry-run/prepare step for mutations, and an explicit, dangerous mutate execution tool that requires user review. Snippets are saved locally (configurable directory) and the server is designed to integrate with agents and tools like Cursor and Claude Desktop for developer workflows.
