"Ruby" matching MCP servers:

Enables comparing Ruby hash literals and converting Ruby hashes to JSON with deterministic diff reports, running locally for privacy.

The IDE for agents — read by symbol, edit against a revision, validate with your own build, revert. It is a local stdio MCP server for coding agents. It reads code by symbol with tree-sitter and real language servers (Go, Java, Scala, TypeScript, Python, Rust, Ruby), edits against a known revision and returns compiler diagnostics with each edit, runs the repository's own build, test etc.

Indexes Ruby on Rails codebases into a queryable graph of associations, routes, callbacks, jobs, and mailers, providing a token-efficient alternative to grep for navigating Rails code via Claude Code.

Automatically reads Sentry issues, investigates them by analyzing your Ruby codebase, explains why issues happened, and provides fix suggestions.

An MCP server that exposes Ruby on Rails implicit dependencies like callbacks, associations, and concerns to AI coding tools.

Provides RuboCop and Rails linting capabilities to AI assistants like Claude and Cursor, allowing them to lint, auto-correct, and manage Ruby code style violations.

Enables agents to query information about gems in a Ruby project's Gemfile, including source code and metadata.

Enables Claude to directly access and analyze Ruby SimpleCov coverage reports for Rails projects. It allows users to retrieve coverage summaries, filter files by coverage rates, and identify specific uncovered lines to streamline test development.
