Rails development skills and workflows for AI agents via MCP.
What is the Rails Agent Skills MCP server?
The Rails Agent Skills MCP server exposes Rails-specific development procedures and expertise through the Model Context Protocol. It provides specialized workflows for feature implementation, code review, maintenance tasks, and domain-specific Rails work like migrations, background jobs, GraphQL, and engine development.
This server gives AI agents access to structured Rails development knowledge and best practices. It organizes work into three main entry points (feature implementation, code review, and maintenance) and provides specialist cards for common Rails tasks like authorization, performance optimization, security review, and testing. Useful for automating Rails development workflows and ensuring consistent application of Rails conventions.
