An MCP server that enables local execution of Rails console commands, providing tools for read-only operations and managed mutations in a local Rails environment.
The MCP Server: Local Rails Runner is designed to facilitate the execution of Rails console commands locally. It is particularly useful for developers who need to perform data wrangling and analysis without navigating complex Admin UIs. The server supports both read-only operations and controlled mutations, ensuring that changes to the database are carefully managed. It integrates seamlessly with tools like Cursor Composer, allowing users to pull in Rails model files as context and execute commands using tools like `execute_read_only`, `dry_run_mutate`, and `execute_mutate`. This setup is ideal for developers looking to streamline their workflow and manage their Rails environment efficiently.
