What is the Rails MCP Server?

An MCP server for Rails projects, allowing LLMs to interact with your application.

What the server does

A Ruby implementation of a Model Context Protocol (MCP) server for Rails projects. This server allows LLMs (Large Language Models) to interact with Rails projects through the Model Context Protocol, providing capabilities for code analysis, exploration, and development assistance.

The Model Context Protocol (MCP) is a standardized way for AI models to interact with their environment. It defines a structured method for models to request and use tools, access resources, and maintain context during interactions.

  • Manage multiple Rails projects
  • Browse project files and structures
  • View Rails routes with filtering options
  • Inspect model information and relationships (with Prism static analysis)
  • Get database schema information
  • Analyze controller-view relationships
