概览

What is SSH Rails Runner?

An MCP server that enables secure remote execution of Rails console commands over SSH. It provides tools for read-only operations and carefully managed mutations in a deployed Rails environment, and works well with Cursor for data wrangling and analysis.

How to use SSH Rails Runner?

Install via npm install and npm run build, then set the environment variables SSH_HOST, SSH_USER, SSH_PRIVATE_KEY_PATH, and RAILS_WORKING_DIR. Integrate with MCP clients like Claude Desktop by adding the server to its mcpServers configuration, or use directly with Cursor Composer.

Key features of SSH Rails Runner

Remote Rails console execution over SSH
Safe read‑only operations
Dry‑run capability for mutations
Execution of approved mutation code snippets
Resource management for code snippets
Works with Cursor and Claude Desktop

Use cases of SSH Rails Runner

Run read‑only Rails console commands on a remote server
Plan and validate database mutations without side effects
Execute approved mutations after explicit review
Perform data analysis and wrangling without a complicated Admin UI

常见问题

What security considerations should I be aware of?

Only use the server with trusted SSH endpoints from your own local machine that is temporarily provided access to the remote environment. Always review all mutations before execution.

What environment variables are required?

You need to set `SSH_HOST`, `SSH_USER`, `SSH_PRIVATE_KEY_PATH`, and `RAILS_WORKING_DIR`.

How do I use SSH Rails Runner with Cursor?

In Cursor Composer, pull in your Rails model files as context, then use the `execute_read_only`, `dry_run_mutate`, and `execute_mutate` tools to query and modify the database.

What tools does the server provide?

Three tools: `run_read_only` for read-only operations, `dry_run_mutate` to plan and validate mutations without executing them, and `execute_mutate` to execute previously approved code snippets.

Does SSH Rails Runner support mutations?

Yes, but only through a two‑step process: first create a dry‑run snippet, then explicitly approve and execute it with `execute_mutate`.
