Rails Agent Skills — Claude Code MCP server: features and setup
This MCP server gives coding agents procedures for Rails implementation, review, and maintenance. Use it to route a task to a relevant Rails specialist.
claude mcp add mcp_server -- docker run -i --rm docker.io/igmarin/rails-agent-skills-mcp:5.1.7What Rails Agent Skills does
The server exposes procedures for Rails work. rails-feature handles changes to application behavior, rails-review checks diffs, and rails-maintenance covers project setup, conventions, refactoring, and engine upkeep. A shared work-router chooses an entry; when the task is clear, you can call a specialist directly.
There are also specialist cards for Rails APIs, authorization, background jobs, GraphQL, Hotwire, migrations, performance, security, engines, setup, and tests. Ruby language patterns are handled by ruby-core-skills. The MCP connection starts a Docker container over stdio, so the docker command must be available.
What it helps with
- change behavior in a Rails application
- review a diff for security or migration risks
- set up Rails project conventions
- handle a GraphQL or background-job task
- assess a migration before production
Example prompts for the agent
- Add an access check to this Rails operation.
- Review this diff for production migration risks.
- Set up this Rails project and check its conventions.
