Rails
The Rails MCP Server is a Ruby implementation that enables Large Language Models to interact with Rails projects through the Model Context Protocol, providing code analysis, exploration, and development assistance. It offers tools for browsing project structures, viewing routes, inspecting models and database schemas, analyzing controller-view relationships, executing sandboxed code, and accessing Rails documentation. The server solves the problem of giving AI models structured, programmatic access to Rails project information for intelligent code assistance and analysis.

Rails MCP Server
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.
What is MCP?
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.
This Rails MCP Server implements the MCP specification to give AI models access to Rails projects for code analysis, exploration, and assistance.
