Can I use this skill to find documentation for specific gems?

Yes, using the Context7 integration, you can resolve library IDs for gems like Devise or RSpec and query their official documentation and code examples.

How does this skill help with code navigation?

By leveraging Ruby LSP tools, Claude can find all references to a specific method or jump directly to the definition of a class across your entire workspace.

What is the Rails MCP Server used for?

The Rails MCP Server allows Claude to interact directly with your Rails application's internal structure to list routes, analyze models, and inspect the database schema faster than manual file reading.

Is the Ruby execution feature safe?

Yes, the mcp__rails__execute_ruby tool is intended for read-only analysis and introspection of your codebase to prevent accidental data mutation.

API Development

Empowers Claude to programmatically analyze Rails codebases, query documentation, and navigate Ruby projects using MCP servers.

The mcp-tools-guide skill transforms Claude into a specialized Rails assistant by integrating three essential MCP servers: Rails MCP for deep codebase analysis, Context7 for real-time documentation retrieval, and Ruby LSP for intelligent code navigation. It enables Claude to skip manual file reading by directly querying models, routes, and controllers, and even allows for read-only Ruby execution to perform complex architectural audits. Whether you are refactoring legacy code or looking up current gem documentation, this skill provides the context-aware intelligence needed for professional Ruby on Rails development.
